DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

Overview

An aspect of some embodiments of the invention relates to causing a user to use his pelvis and/or his core muscles for balancing his body while being supported by a movable seat. Optionally, the seat has a saddle shape. Optionally, the seat is sized and shaped to support the user’s pelvis region while the user straddling the seat.

In some embodiments, the movable seat may be adjusted, for example with regard to size and its shape to change the engagement of the seat with the user. Optionally, such change is used to change the location and/or force of contact between the seat and the user’s body, for example according to the size of the user’s body and/or according to a therapeutic or a training program.

In some embodiments, the movement of the seat includes inclination and/or rotation. Optionally, the movement is caused by the user which applies force using his pelvis, thighs and/or core muscles on a selected portion of the seat. Optionally or alternatively, the movement is caused or otherwise meditated by one or more actuators positioned externally or integral with portions of the pelvic training device (PTD).

In some embodiments of the invention, the seat inclines and/or rotates without significant translational movement. For example, the saddle point of the seat moves less than 30 cm, less than 20 cm or intermediate amounts during an inclination of 60 degrees and/or during a rotation of 90 degrees. Optionally, a hinge point for the seat is located within 30 cm, 20 cm, 10 cm or intermediate distances of the saddle point of the seat.

Optionally or alternatively, the seat inclines and/or rotates along with an additional translational movement component. For example, the saddle point of the seat may move laterally to a distance between 0 and 30 cm, optionally, to a distance between 0 and 20 cm, optionally, to a distance between 0 and 10 cm or intermediate distances in relation to a resting position thereof.

In some embodiments, the movable seat has a low profile, which is defined by a low frontal and rear walls and optionally selected to avoid interfering with flexing of the user’s trunk. Optionally, the highest edge of the seat (in relation to the ground) does not exceed the height of the pelvis bones, such that the abdomen and lower back of the mounted user are free to be bend in relation to a sagittal and/or in relation to a frontal plane of the user’s body.

In some embodiments, the user is supported by the seat and his feet are not supported by or rested on any surface. In some embodiments, the user is supported above the ground at a height which is between 60 cm to 140 cm.

In some embodiments, the user is supported at a height which is between, for example, 60 to 80cm, 80 to 90 cm, 90 to 100 cm, 100 to 110 cm, 110 to 120 cm, 120 to 130 cm, 130 to 140 cm, and/or 100 to 150 cm and/or intermediate or greater heights above the ground.

In some embodiments of the invention, restriction of contact between feet and the ground is by supporting the seat on a vertical supporter, which extends from a base or from the floor and having a length which is longer than the length of the user’s legs.

In some embodiments, the vertical supporter supports the seat above the ground at a height which is at least higher than 60 cm.

A potential advantage of restricting the user’s feet from touching the ground is preventing user posture control by applying force to the ground (e.g., as in regular, standing, posture). Such preventing may force the user to use mainly his thighs, pelvis and/or other core muscles to stabilize himself while being seated on the seat.

In some embodiments, the user is supported at various body inclinations in relation to the ground, which are followed by inclination of the movable seat. Optionally, the inclinations include a lateral tilt (e.g., to the left or to the right) and/or a frontal/rear tilt.

In some embodiments, the seat is supported at an inclined position using a flexible connector, for example a spring, optionally positioned underneath the movable seat and which interconnects the seat and the vertical support. Optionally, the spring is configured to bend in any direction in relation to the ground.

In some embodiments, rotation of the movable seat includes a clockwise and/or a counterclockwise rotation. Optionally, the rotation is by rotation of the vertical supporter, which optionally may rotate about its longitudinal axis. Optionally, rotation of the seat is by rotation of the flexible connector (e.g., a spring and/or a joint) and/or by a combined rotation of the flexible connector and the vertical supporter. In some embodiments, the movements are preformed according to a training and/or according to a therapeutic protocol.

An aspect of some embodiments of the invention relates to exercising a user’s skeletal and/or core muscles, by supporting his body above the ground by one or more support means. In some embodiments, the support means are positioned at one or more locations around the user’s body. In some embodiments, the support means include a movable seat which is positioned underneath the user and additional one or more tensile elements (e.g., straps).

In some embodiments, one or more straps are mounted on (e.g., tied around) one or more portions of the user’s body and are further connected to one or more peripheral anchoring point(s). Optionally, the anchoring points are located at different locations on a peripheral frame which surrounds the mounted user. In some embodiments of the invention, one or more straps are held by the user.

In some embodiments, the user may voluntary incline his body to a desired inclination angle by pulling a desired strap in a desired pulling direction. Optionally or alternatively, the body of the user may be inclined involuntary, e.g., following movements of components in the pelvic training device (PTD). In some embodiments of the invention, movement is due to seat movement. Optionally or additionally, movement is due to a change in length or elasticity of a tensile element (e.g., shortened by a motorized actuator or allowed to extend by releasing a blocking actuator). In some embodiments, inclination of the user’s body may be beneficial for training the user and/or strengthening at least some muscles of his body.

In some embodiments, the mounted user may be rotated following rotation of a vertical supporter and may be pulled to one or more directions, following pulling of a selected strap, such that the user is enforced to stabilize himself on the movable seat at various movement patterns.

In some embodiments, supporting a user by the additional tensile elements may be advantageous in allowing a large inclination angles and/or along fast rotational movement which may enable training different muscles at different training difficulties. Optionally or alternatively, supporting a user by the additional tensile elements may be advantageous in allowing inclining at precise inclination angles and/or along slow rotational movement which may enable training different muscles at different training difficulties.

An aspect of some embodiments of the invention relates to exercising a user’s skeletal and/or core muscles using real-time guidance. Optionally, the real time guidance includes directing the user to perform selected movements, for example by inclining his body while sitting on a movable seat. In some embodiments, the real-time guidance comprises acquiring body motion data by one or more sensors. Optionally, the sensors detect usage data from the user’s body. Optionally, usage data includes movement patterns such as inclinations and/or rotations of the movable seat. Optionally or alternatively, usage data includes pressure applied by portions of the user’s body on the seat. Optionally, usage data is detected by sensing motions of components of the pelvic training device (PTD). In some embodiments, the detected data is analyzed. Optionally, the data is displayed.

In some embodiments, the acquired data includes movement parameters (applied by the mounted user) such as directions and/or distances (such as centimeters or millimeters) and/or velocities (e.g. centimeters per second) and/or inclination angles (e.g. from 0 to 180 degrees) detected by motion sensors. Optionally, the acquired data includes pressure parameters (applied by the mounted user) such as pressure intensity, frequency by one or more pressure sensors. Optionally, the acquired data includes physiological parameters such as blood pressure, body temperature, and/or neural activity level.

Optionally, the acquired data is detected by an image sensor (e.g., a camera), which monitors the motions of the user.

In some embodiments, the acquired data is transmitted to a processing unit, which processes the acquired data and transmits signals to a displaying unit, such analysis may be performed by an embedded control software.

In some embodiments, the data (e.g., acquired, processed and/or guidance) is displayed by a graphical user interface (GUI) on a screen. Optionally or alternatively, data is transmitted to the user by a visual and /or by an audial and/or by a vibrational signaling, and/or by combination thereof.

An aspect of some embodiments of the invention relates to traction of one or more joints within the user’s body. Optionally, traction is provided by modifying the posture of the mounted user when sitting on a movable seat. In some embodiments of the invention, the traction includes modifying the relative orientation and/or the gap between corresponding bones within one or more joints of the user’s body in relation to each other. Optionally, such modification includes coupling one or more straps to one or more portions of the user’s body. Optionally, the body of the user is pulled to one or more directions.

In some embodiments of the invention, traction is provided by the forces on two sides of a joint being in different amounts and or directions, for example, gravity acting in one direction and a strap in another. Optionally, the method of support of the user (not by his feet) allows part of the weight of the user to apply such a force.

Optionally, pulling is initiated and/or controlled by the user which pulls a strap to a desired direction, and move his body towards the pulling direction. Optionally or alternatively, pulling is by one or more actuators (such actuators may be motorized), which are connected to the straps that may pull the user by the straps to a desired directions.

Potential benefits of joint traction includes promoting blood circulation within the joints, rehabilitation of defective joints and/or improving neural activity within the joints and/or in tissues near the joint (e.g., within 10 cm of the joint).

In some embodiments, the pelvic training device (PTD) and/or system described herein is used for therapeutic applications such as physiotherapy and/or rehabilitation and/or bone fractures and/or joints injuries and/or ligaments/tendon injuries.

In some embodiments, the pelvic training device (PTD) and/or system described herein is used for non-therapeutic applications such sport and/or fitness exercises.

In some embodiments, the pelvic training device (PTD) and/or system described herein is used for cosmetic applications which involve re-shaping of one or more areas of the user’s body.

An aspect of some embodiments of the invention relates to a seat which is configured to move side-to-side and/or front-to-back and/or rotate, relative to a base of the seat.

Such movement potentially causes a user to exercise abdominal muscles and/or core muscles to find a stable seating position.

In some embodiments degrees of freedom of movement of the seat relative to the base of the seat include one or more of:

Side-to-side swaying;

Forward-and-backward swaying;

Side-to-side or clockwise-and-counterclockwise rotation; and

Up-and-down-bouncing.

In some embodiments, the movement in any one or more of the degrees of movement is optionally against resistance, for example movement against resistance of a spring.

Such movement potentially causes a user to balance on the potentially shifting seat, and find a healthy seating position.

In some embodiments, the seat can optionally bounce up-and-down, potentially adding to the exercise aspect. In some embodiments, the seat can be locked from movement relative to the base of the seat, providing stability when needed.

In some embodiments, the seat can be locked by the user leaning back against a back cushion.

In some embodiments, controls are provided to enable each one of the degrees of freedom of movement described above.

In some embodiments, a separate control is provided to enable locking and unlocking each one of the degrees of freedom of movement described above separately.

In some embodiments, a control is provided to optionally enable locking and unlocking more than one of the degrees of freedom of movement described above together.

In some embodiments, one or more sensors are provided to enable measuring movement at one or more of the degrees of freedom of movement described above.

In some embodiments the seat enables a user to sit with the pelvic joints straight, or bent at an angle.

An aspect of some embodiments of the invention relates to a seat which is configured to move side-to-side and/or front-to-back relative to a base of the seat.

In some embodiments, the seat performs a swaying or wobbling movement atop a stiff support. The swaying movement optionally occurs nearer the seat bottom than the floor. In some embodiments the movement is a movement of a seat swaying atop a post, rather than a seat rigidly connected to a post which sways at its bottom, near the floor.

In some embodiments, a flexible connector or spring is attached to a seat, extending down, and connected to a vertical support or post. In some embodiments, the flexible connector surrounds a top portion of the vertical support. The portion of the flexible connector surrounding the top portion of the vertical support cannot sway much, if at all. A portion of the flexible connector extending above the top portion of the vertical support can sway flexibly.

In some embodiments, an amount by which the flexible connector extends above the top portion of the vertical support can be adjusted. The adjustment potentially adjust a stiffness of the swaying, and/or potentially adjusts a range of motion of the swaying, as expressed in degrees from a central position, or as expressed in centimeters from the central position.

An aspect of some embodiments of the invention relates to using sensors to measure movement of the seat along one or more of the degrees of freedom which the seat can move, and using values thus measured in a computer application. Re-enumerating the degrees of freedom listed above, the degrees of freedom of movement of a seat according to some embodiments include one or more of:

Side-to-side;

Forward-and-backward;

Side-to-side or clockwise-and-counterclockwise rotation; and

Up-and-down.

It is noted that 4 degrees of freedom are listed above.

In some embodiments, the sensors send values measured for movement along one or more of the degrees of freedom to a processor, and the processor optionally uses one or more of the values.

Some uses for the sensor values include:

a) Controlling movement of a cursor on a display.

b) Controlling movement of a game control on a display, potentially enabling playing a game.

It is noted that the above-mentioned four degrees of freedom potentially enable controlling a display in one, two, three or four dimensions (by way of a non-limiting example including time as a dimension).

By way of a non-limiting example, playing Pong, which requires controlling movement of a paddle along one dimension, can be done by associating side-to-side movement, or forward and backward movement, to movement of a paddle used in the game.

By way of a non-limiting example, controlling a kayak simulation game, for example by rotating the seat to control the direction of the simulated kayak, and leaning sideways to control a weight of a simulated paddler in the simulated kayak

By way of another non-limiting example, controlling a snow ski simulation game, for example by rotating the seat to control the direction of the simulated skis; leaning sideways to control a sideways leaning of a simulated skier on the simulated skis; leaning forward or backward to control forward and backward lean, and moving, or bouncing, up and down on the seat to simulate jumping or skiing over moguls.

c) Controlling movement of a device movement in at least one, two, three or four degrees of freedom.

d) Tracking a user’s movement on the seat. Such tracking can sense changes in a user’s posture. In some embodiments, a display displays one or more measures of the user’s posture to the user. In some embodiments, the user is additionally displayed desired values, and asked to perform exercise on the seat so as to reach the desired values. Exemplary Embodiments

Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways.

The following exemplary embodiments describe, inter alia, a pelvic training device (PTD) comprising a movable seat which is sized and shaped to house a pelvis region of a mounted user. In some embodiments, the seat is elevated above the ground to a height which is at least longer than the length of the mounted user’s leg.

In some embodiments, the device defines a sagittal plane and a frontal plane. Optionally, the seat can incline in a sagittal and/or in a frontal direction. Optionally, the seat may rotate about its longitudinal axis, for example by rotation of a vertical supporter which supports the seat and which is further operable to rotate clockwise and counterclockwise in relation to the seat’s longitudinal axis. In some embodiments, the seat is connected to the vertical supporter by a spring. Optionally, the spring is bendable at any direction. Optionally, the spring may twist about its longitudinal axis (which is parallel to the seat’s longitudinal axis).

In some embodiments, movements are transmitted from the mounted user’s body, through the seat to the vertical supporter and to the bendable spring. For example, when the user voluntary and/or involuntary applies pressure or moves his body towards a certain direction.

Optionally, movements are transmitted through the vertical supporter and through the spring to the seat, for example following rotation of the vertical supporter and/or following bending/ twirling of the spring.

In some embodiments, because a contact between the mounted user’s feet and the ground is restricted, the user is forced to stabilize himself on the seat by his pelvis and/or by his core/skeletal muscles. In addition, and while said seat moves, said self- stabilization is required at various inclinations of the user’s body in relation to the ground which further leads to pelvis and core/skeletal muscles training.

In some embodiments, the user may use one or more tensile elements, e.g., supporting straps, which are connectable to his body, which are further connected to external anchoring locations around his body, to stabilize himself on the seat. Such supporting straps may enable inclinations of the user at a wide range of angles while not slipping off the seat (comparing to an inclinations without such additional straps), which may help to train the user at a wide range of movements as part of a training/therapeutic protocol. Referring to the drawings, Figures 1A-B show a schematic front illustration of a pelvic training device (PTD) 100, according to some embodiments of the invention. The system comprises an interface (e.g., a seat 101) on which a user 111 (figure IB) is mounted. Optionally, the interface supports a portion of the user’s body such as the area between the lower abdomen and the bottom of the pelvis. Optionally, the interface supports the user also by his thighs.

Optionally, seat 101 is mounted by a flexible connector 102, for example a spring (or by more than one spring) on a vertical supporter 103. Optionally, spring 102 supports movement of seat 101 relative to other parts of system or relative to the ground. Optionally, spring 102 connects seat 101 to a vertical supporter 103.

In some embodiments, pelvic training device (PTD) 100 includes one or more anchoring locations 112 (e.g., barbs and/or hooks), optionally surrounding seat 101. In some embodiments, anchors 112 are mounted to or integral with a peripheral ring 114. In some embodiments, device (PTD) 100 includes one or more straps 113 connectable to anchoring locations 112 which are further connectable to the user’s body.

In some embodiments, pelvic training device (PTD) is made for adult users. Optionally, each part of the device can bear a weight of, for example, 0 -350 kg, 0-150 kg, 150- 200 kg, 200- 300 kg and 300-350 kg static or dynamic, without breaking and/or plastically deforming.

In some embodiments, each part of pelvic training device (PTD) 100 can bear loads for example of between 0 to 3500 N, 0-1500 N, 1500- 2000 N, 2000-3000 N and 3000-3500 N without breaking and/or plastically deforming.

Movable seat:

In some embodiments, seat 101 is saddle shaped. Optionally the seat comprises one or more convex portions (e.g., portions 440 and 450 at figure 4A), optionally positioned at a front portion of seat 101 (in front of the mounted user) and at a rear portion of seat 101 (behind the mounted user). In some embodiments, seat 101 includes one or more concave portions (e.g., portions 460 at figure 4A). In some embodiments, the concaved portions are positioned between the front portion and the rear portions, in vicinity of the thighs of the mounted user 111 (e.g., lateral portions).

In some embodiments, seat 101 includes a central arch (e.g., portion 410 at figure 4A) positioned between the convex portions and the concave portions. In some embodiments, the central arch comprises a saddle point. In some embodiments, each of the convex portions extends upwardly away from the arch. In some embodiments, each of the concave portions extends downwardly away from the arch. In some embodiments, the height of each of the convex portions, which is defined as the height above the central arch, does not exceed the height of the user’s ilia bones.

In some embodiments, the distance between the front and rear convex portions is long enough to house the pelvis of the user. Optionally, the distance is at most 40 cm. optionally or alternatively, the distance is at most 35cm, 30cm.

Optionally, the distance is between 20 cm to 40 cm. optionally, the distance is between 20 cm to 35 cm. optionally, the distance is between 20 cm to 30 cm.

In some embodiments, user 111 is mounted on a top portion of the seat (which faces upwards) with his legs spread apart from each other.

In some embodiments, the height of seat 101 above the ground is defined by the length of vertical supporter 103, said seat 101 is mounted on a distal end (in relation to the ground) of the vertical supporter 103.

In some embodiments of the invention, user 111 (shown for example, at figure IB) is forced to stabilize himself on seat 101 by activating the muscles of his pelvis and thighs and/or his inner core-muscles; this activation may be advantageous in training these body areas.

In some embodiments, seat 101 has a fixed size and/or shape. Optionally or alternatively, as shown for example at figure 15, seat 1500 may comprise one or more portions (for example one or more frontal 1501 portions, one or more rear 1501 portions, and one or more lateral 1502 portions). In some embodiments, the portions of the seat may move in relation to each other, thereby to adjust the size and/or shape of the seat. Potential benefits of adjusting the location and/or extent of contact area between the seat and the user’s is forcing the user to apply modified amount of force on parts of the seat to maintain his stability.

In some embodiments, flexible connector (e.g., spring) 102 may be bent in relation to the ground and/or in relation to vertical supporter 103 following force which is applied on seat 101. In some embodiments, the inclination of spring 102 may be at any positive or negative inclination angle in relation to a sagittal/frontal plane of pelvic training device (PTD) 100 and/or in relation to a sagittal/frontal plane of the user’s body. In some embodiments, inclination is between 0 to 180 degrees. In some embodiments, inclination to about 180 degrees may be advantageous in forcing the user to activate additional muscles as part of the wide range movement. In some embodiments, such a wide range of movement is by supporting portions of his body (e.g., legs and/or hands) to additional straps.

Optionally, said inclination is between 0 to 150 degrees. Optionally or alternatively, said inclination is between 0 to 90 degrees. In some embodiments, inclination between 0 to 90 degrees may be advantageous in training the user to perform small range movements (e.g., movements that requires pelvis movements within 10, 15, 20 degrees while being inclined) to increase precise and control of his muscle. Optionally or alternatively, the inclination is between 0 to 75 degrees. Optionally or alternatively, the inclination is between 0 to 50 degrees. In some embodiments, inclination is between 0 to 25 degrees, or at any angle between 0 to 180 degrees.

Here are definitions of coordinate systems, which may be used to explain some embodiments of the invention:

In some embodiments, pelvic training device (PTD) 100 is divided into a frontal part (which supports the front portion of the user’s pelvis), lateral parts (which supports the pelvis and thighs of the user) and a rear part (which supports the rear portion of the user’s pelvis).

Optionally, pelvic training device (PTD) 100 is divided by a frontal plane, which divides pelvic training device (PTD) 100 to the frontal and the rear parts. Optionally, pelvic training device (PTD) 100 is divided by a sagittal plane that divides pelvic training device (PTD) 100 to the lateral (left and right) parts.

In some embodiments, the frontal and the sagittal planes are perpendicular in relation to each other.

In some embodiments, said frontal and sagittal plans divide the user’s body at the same manner, namely the sagittal plane divides the user’s body to a left and right parts and the frontal plane divides the user’s body to a frontal part and to a rear part.

Movement of an exemplary seat 101:

In some embodiments, movements of seat 101 include inclination and/or rotation or combination of such movements. Optionally, movements are initiated by user 111, or by activation of one or more actuators 117 (for example by an electric motor). In some embodiments, the actuators may be mounted to or integral with one or more parts of pelvic training device (PTD)

100, for example, with vertical supporter 103, peripheral frame 114, spring 102 and/or with seat

101. In some embodiments, the actuators are operable to cause movements of one or more parts of pelvic training device (PTD) 100 in relation to the rest of device 100. In some embodiments, actuators 117 are powered by one or more of electricity and/or pneumatic and/or hydraulic pressure.

In some embodiments, seat 101 may rotate following rotation of vertical supporter 103 which may rotate about a bearing, for example bearing 104. Optionally, vertical supporter 103 may rotate following activation of actuator 117.

Optionally, bearing 104 is positioned at a lower portion of vertical supporter 103, and is further connected to base 115 of pelvic training device (PTD). Optionally, bearing 104 is positioned at an upper portion of vertical supporter 103, and is further coupled to spring 102 or directly to seat

101 itself (as illustrated for example at figure 3B).

In some embodiments, actuator 117 is controlled by a control signal, provided, for example, by a controller (e.g., control unit) 118.

In some embodiments, the control signal is a wireless signal, which is optionally transmitted from a remote control unit (e.g., units 121, and/or 122, and/or 123, shown for example, at figure IB). In some embodiments, remote control unit may include a mobile device 122 or remote control 121 having an embedded control software and a communication circuitry, which may transmit a wireless signal according to the embedded control software therein. Optionally, signal is transmitted from an external server, such as 123 and delivered to actuator 117 (and/or controller 118) via, for example, an Internet, with a last step optionally being wireless, for example, using WiFi or Bluetooth standards.

In some embodiments of the invention, control software may be used to control one or more movement of seat 101, rotation of vertical supporter 103, elongation and/or shortening of straps 113 and/or bending of spring 102.

In some embodiments, the control software is optionally software which runs on a user’s personal computer and/or on a user’s mobile device, such as a smart phone or tablet.

In some embodiments, connector 102 comprises two or more segments having a degree of movement freedom in relation to each other.

Figure 2A shows a schematic illustration of a user 111 mounted at an upright posture, namely a“starting/ native position” on a seat 101. The figure shows an exemplary two straps 113 wound around the user’s body, by which the user is secured above the ground to peripheral ring

114.

In some embodiments, the location of the pelvis of the user is restricted for example due to the shape of seat 101 which comprises a rear and a front elevated protrusions which blocks slipping off of the user forward or backwards from the seat. In some embodiments, the pelvis is restricted for example to a desired height above the ground. Optionally, the height is defined by the height of seat 101.

Optionally, user 111 can incline his body to any desired direction, thereby to incline seat 101 as well. As user 111 inclines, the location of his center of gravity typically changes. In some embodiments, the displacement of the location of the user’s center of gravity relative to its location at the starting position following different body inclinations and postures involves activation of different muscles groups. Optionally, such activation may be advantageous in training different muscles in the thighs and/or in the pelvis of the user.

Lateral tilt:

In some embodiments, user 111 may incline a portion of his body either to the left side or to the right side. During lateral inclination, the user is typically required to apply pressure by his inner thighs and pelvis on the lateral portions of seat 101 by bringing his thighs towards the seat to grip the seat, in order to maintain his stability.

In some embodiments, seat 101 may be inclined both laterally and/or to the front/rear.

Frontal and rear tilt:

In some embodiments, user 111 may incline the seat in relation to the ground, for example by movements of his pelvis to a frontal and/or in to a rear inclinations.

In some embodiments, user 111 is secured by strap 113 to peripheral frame 114. Optionally, as the user tilts his body and/or as seat 101 inclines in relation to the starting position, the movement may be restricted according to the location and/or length of strap 113 in relation to the movement direction.

In some embodiments, strap 113 may be fastened to the body of the user firmly. Optionally, the strap may be fastened loosely, thereby restricting the movement at a lager inclination angles.

Optionally, strap 113 may be elastic and can be stretched when pulled. In some embodiments, a stretchable strap may be advantages by causing gradual pulling resistance, which may allow different training difficulties. Straps’ connectivity with the user’s body

In some embodiments, strap 113 is anchored to a selected one or more points at peripheral frame 114.

Referring now to figure 2C that shows a schematic illustration of a surface area of an exemplary a strap 113. In some embodiments, the strap may include a smooth surface area (for example at a side that doesn’t faces the user’s body). Optionally or alternatively, the strap may include a rough (e.g., bumpy) surface over at least a portion thereof. Optionally, the bumpy surface includes for example a series of knobs.

Optionally, the strap may include both smooth and bumpy surface areas at the same side. A potential advantage of a bumpy surface may include increasing of the friction as the strap encounters the body of the user such that an enhanced grip of the body may be achieved.

Strap’s connection with the peripheral frame:

In some embodiments, as straps 113 being connected to different hooks 112, the user’s body may be supported from various directions. In some embodiments, supporting the user from various directions may be advantageous in training his body muscles at various difficulty levels.

Figure 2E shows an exemplary connector assembly 1120 of strap 113 to frame 114, for example in a form of a spindle 1122. In some embodiments, assembly 1120 divides strap 113 into at least two edges. In some embodiments, assembly 1120 includes a shaft 1124 portion by which the assembly is connected to frame 114.

In some embodiments, spindle 1122 rotates freely about shaft 1124. In some embodiments, strap 113 is wrapped around spindle 1122. Optionally, by pulling a first edge 1135 of strap 113, optionally by the user, the length of a portion of strap 113 which is un- wrapped around spindle 1122 becomes longer and a second edge 1137 of strap 113 becomes shorter, and to the opposite, according to the straps pulling direction.

In some embodiments, spindle 1122 rotates upon activation of an actuator, such as an electric motor. In some embodiments, the actuator may be activated following a control signal(e.g., an electric signal, pneumatic signal and/or mechanical signal) received for example from control unit 118 as shown for example at figure IB.

Movement directions of the movable seat

In some embodiments, moveable seat 101 is inclined in relation to the ground at an inclination angle which is between 0° to 180°, wherein 0° inclination is when the longitudinal axis of seat 101 is perpendicular to the ground and 90° inclination is when the longitudinal axis is parallel to the ground. Optionally or alternatively, the inclination angle is between 0° to 150°. Optionally or alternatively, the inclination angle is between 0° to 90°. Optionally or alternatively, the inclination angle is between 0° to 45°.

Optionally, the user may apply pressure on seat 101 towards a desired direction, for example by his pelvis. Optionally, the location of the user’s center of gravity changes the inclination of the seat. In some embodiments, the location of the center of gravity is modified by the posture of the user while being mounted on the set, which causes inclination of the seat.

In some embodiments, flexible connector (e.g., spring) 102 which supports seat 101 may oppose the inclination of seat. In some embodiments, flexible connector 102 may resist inclination of seat 101. Optionally or alternatively, spring 102 may resist inclination of seat 101. In some embodiments, the flexible connector can be as flexible as the spring. Optionally, flexible connector (e.g., spring) 102 is operable to bend in relation to the ground and/or in relation to the longitudinal axis of vertical supporter 103 following load (N) which is applied on the spring.

In some embodiments, flexible connector (e.g., spring) 102 is operable to bend to an angle between 10 to 120 degrees in relation to the longitudinal axis of the vertical supporter upon a load of between 300 to 1200 (N) which may be applied on said seat.

In some embodiments, flexible connector (e.g., spring) 102 bends to an angle between 10 to 120 degrees upon a load of between 300 to 400 (N), 400 to 500 (N), 500 to 600 (N), 600 to 700 (N), 700 to 800 (N), 800 to 900 (N), 900 to 1000 (N), 1000 to 1200 (N) and/or 1200 to 1300 (N) and/or 1300 to 1400 (N) and/or 1400 to 1500 (N) and/or 1500 to 1600 (N) and/or intermediate or greater loads.

Movement directions of the vertical supporter

In some embodiments, vertical supporter 103 rotates about its longitudinal axis. In some embodiments, seat 101 rotates along rotation of vertical supporter 103.

In some embodiments, the rotation is clockwise or counterclockwise.

In some embodiments, vertical supporter 103 is mounted on base 115 by a pivotal bearing which is further connected to a first end of at least two retrieval springs 105. In some embodiments, each of retrieval spring 105 is connected by its second end to base 115. In some embodiments, each of the retrieval springs 105 may extend following rotation of vertical supporter 103. In some embodiments, each of the retrieval springs 105 may resist rotation of vertical supporter 103 according to a spring’s constant, for example by contracting back to the spring’s resting length (namely an un-stretched length).

In some embodiments, rotation of vertical supporter 103 is modified by the amount of force (N) which is applied by the user, (e.g., by his pelvis) on seat 101 towards a desired rotation direction. In some embodiments, as the user’s pushes the seat to a desired direction, rotation of vertical supporter 103 in relation to a resting position which is connected to seat 101, for example by flexible connector 102 occurs.

In some embodiments, rotation of seat 101 and vertical supporter 103 is modified for example by the location the user’s center of gravity, said location may move according to the posture of the user while being mounted on seat 101.

In some embodiments, rotation of seat 101 and vertical supporter 103 is modified both by the amount of force (N) which is applied by the user on the seat and by the user’s center of gravity.

In some embodiments of the invention, force of 10 to 350 N causes rotation of vertical supporter 103 of between 10 to 210 degrees clockwise and/or counterclockwise in relation to the resting position. In some embodiments, force of 10 to 350 N causes rotation of vertical supporter 103 of between for example 10 to 40 degrees, 40 to 10 degrees, 100 to 140 degrees, 140 to 180 degrees, 180 to 210 degrees and/or intermediate or greater rotation angels.

In some embodiments, extension of retrieval spring 105 between 5 and 25cm requires force which is between 10N to 350N. Optionally, extension of retrieval spring 105 between 5 to 25cm requires force which is between 50N to 100N, 100 to 150N, 150 to 200N, 200 to 250N, 250 to 300N and/or 300 to 350N and/or intermediate or greater loads.

Optionally, the second end of retrieval spring 105 is connected for example via a carabiner 1051, as shown for example at figure 3A (i). Optionally or alternatively, retrieval spring 105 is connected to base 115 via a threaded screw 1053, as shown for example at figure 3A(ii). Optionally, the tension of retrieval spring 105 can be modified, for example by threading screw 1053 deeper into the wall of base 115.

In some embodiments, pivoting of vertical supporter 103 about its longitudinal axis is by a retrieval spring 302, which is mounted at a top end of vertical supporter 103, as shown for example, at figure 3B. Optionally, retrieval spring 302 connects seat 101 with vertical supporter 103. In some embodiments, retrieval spring 302 is disposed inside a housing (II) which is positioned on a top end of vertical supporter 103. According to some embodiments, rotation of vertical supporter 103, for example by the user, stretches retrieval spring 302. Optionally, retrieval spring 302 opposes rotation of vertical supporter 103 and restores vertical supporter to its starting position. Optionally or alternatively, retrieval spring 302 opposes rotation of seat 101 and restores seat 101 to its starting position.

Referring now to figure 4A that shows a perspective view of a seat 101 and to figure 4B that shows a front view of a seat 101, according to some embodiments of the invention.

In some embodiments, seat 101 comprises a front and rear portions having a low profile. In some embodiments, the front and rear portions supports the pelvis region and restricts its location to a region between the frontal and rear portions.

According to some embodiments, seat 101 comprises a central arch 410 extending in the medial region of seat 101 between the front and rear portions. In some embodiments, central arch 410 connects lateral left wall and lateral right wall 460 of seat 101 (as shown for example, at figure 4A). Optionally, central arch 410 has a width (shown for example, at figure 4B) which is in a range of 1 -25 cm, for example between 1-12 cm, 12-25 cm, 5-15 cm, 7-20 cm or any intermediate, smaller or larger widths. In some embodiments, the width of central arch 410 defines the extent of straddle between the user’s legs when sitting on seat 101 and may be advantageous in modifying the extent of traction for example of the user’s hips joint and/or the traction between vertebrates within the user’s spinal.

In some embodiments, as shown for example at figure 4B, the lateral portions (e.g. left wall 408 and the right wall 406) are long enough to support the user’s thighs. Optionally, each of the walls comprises a maximal length, defined by the distance between the central arch 410 and the lowest edge of each wall. In some embodiments, the length is at most the length of an adult’s thigh. In some embodiments, the length is between 5-40cm. optionally, the length is between 5-30cm. optionally or alternatively, the length is between 5-20cm, or any intermediate, smaller or larger value.

Optionally, inclination between the walls is by an actuator 412 which is operable to move at least one of the walls in relation to the other.

In some embodiments, modification of the inclination between the lateral walls may be advantageous in modifying the extent of traction for example of the user’s hips joint.

In some embodiments, the front portion and rear portion of seat 101 protrude in a direction away from central arch 410. Optionally, the distance between at least a portion of front portion 440 and at least a portion of rear portion 450 can be modified, for example by inclining front portion 440 and rear portion 450 in relation to each other.

Optionally, inclination between the front and rear portions is by an actuator 470 which is operable to move at least one of the portions in relation to the other.

In some embodiments, modification of the inclination between the front and rear portions may be advantageous in modifying the amount of pressure, which is applied, on the user’s pelvis, for example according to a desired training and/or therapeutic program.

In some embodiments, the front portion has inward notch, for example, notch 420 which is shaped to fit the junctional area between the lower abdomen and the thighs. In some embodiments, the rear portion has an inward notch, for example notch 430 which is shaped to fit the junctional area between the lower back and the thighs.

In some embodiments, frontal and rear portions are made of a rigid composition which is strong enough to support the weight of the user, when mounted on seat 101. For example, the portions may bear a weight of up to 350kg without break.

The figure displays data which is acquired by sensors which are embedded in the pelvic training device (PTD).

In some embodiments, the GUI may include a table. Optionally, the GUI may include a graph or combination thereof. In some embodiments, the table may be divided into one or more columns, each represents a portion of seat 101 (e.g., a left / right/ frontal/rear side of the seat.)

In some embodiments, the table may include one or more rows, in which usage parameters, such as applied pressure and/or movement parameters per seat’s portion may be presented.

Optionally, the data may include pressure which is applied by portions of the user’s pelvis on portions of the seat, for example on seat-body contact area (as shown for example, at figure 5). In some embodiments, the data may include representation of movements of the seat while it moves in certain directions.

In some embodiments, the representation includes a color gradient. Optionally, the representation is represented by a graph that shows for example a measured pressure vs. time. In some embodiments, the representation includes a surface map.

In some embodiments, the GUI may include a planned usage vs. actual usage parameter’s representation. For example, a planned pressure on a certain portion of the seat (for example on the front portion) may be presented as dashed surface map which is being filled by color as the deviation of pressure which is applied by the user on the selected seat portion becomes smaller or larger.

In some embodiments, representation may be advantageous in providing real time data, regarding the manner by which a certain posture of the user’s body produces a pressure pattern on portions of the seat.

Optionally, the representation may be indicative for example for detection of some physiologic deformities (e.g., pelvis and/or core muscles inferior function) and/or muscles reduced/ enhanced activation level.

Figures 14-19 show perspective views of an exemplary design of a segmented seat, according to some embodiments of the invention.

The figures show exemplary configurations of a segmented seat, for example a folded or an un-folded configuration. In some embodiments, the figures show means for altering the orientation (e.g., the inclination and/or the position) of portions of the segmented seat in relation to each other.

Referring now to Figure 14 (I-IV) that show a perspective views of an exemplary design of a segmented seat 1400, according to some embodiments of the invention. In some embodiments, seat 1400 comprises one or more frontal and rear portions 1401. Optionally, each of the frontal and rear portions 1401 contacts the frontal and rear portions of the user’s pelvis respectively.

Referring now to Figure 15(I-IV) that shows a movable segmented seat 1500, comprising one or more separated movable lateral portions 1502. Optionally, each of lateral portions 1502 contacts the external sides of the left and right thighs of a user respectively.

In some embodiments, lateral portions 1502 are connected to each other or to another portion of seat 1500 by a joint (not shown) disposed between lateral portions 1502 and a portion of seat 1500. Optionally, lateral portions 1502 may be folded downwards (e.g., folded configuration) and/or may be un-folded (e.g., un-folded configuration). In some embodiments, a folded configuration may force the user to spread his legs apart from each other to a smaller straddle.

Optionally, an un-folded configuration may force the user to widen his straddle which may affect traction of his hip joint.

Optionally, lateral portions 1502 may be partially folded. In some embodiments, movement of lateral portions 1502 may be modified by an actuator, for example actuator 1506, (e.g., an electric motor) which is connected to the lateral portions and to at least another portion of seat 1500, and inclines each lateral portion 1502 to a desired inclination. Optionally, actuator 1506 may be operable according to a control signals which may be transmitted from/to a control unit (e.g., control unit 118, shown at figure 1A).

In some embodiments, lateral portions 1502 may move in relation to each other for example by a ratchet assembly (illustrated as a dashed line 1506) which allows a linear movement which may result of inclination of lateral portion 1502 in only one direction. Optionally, ratchet assembly 1506 may prevent motion (e.g., inclination) in the opposite direction.

In some embodiments, inclination of lateral portions 1502 causes traction of the hip joint, for example in accordance with an inclination of lateral portions 1502 in relation to the longitudinal axis of pelvic training device (PTD) 100. In some embodiments of the invention, a modified inclination of lateral portions 1502 forces the user to apply a modified amount of pressure with his legs laterally, in a direction towards or away lateral portions 1502 of seat 1500 in order to maintain his stability.

In some embodiments, the frontal/rear portions 1501 are connected to each other or to another portion of seat 1500 by a joint (e.g., joint 1504). Optionally, frontal/rear portions 1501 may move in relation to each other. Optionally, frontal/rear portions 1501 may be inclined in relation to the longitudinal axis of pelvic training device (PTD) 100. Optionally, frontal/rear portions 1501 may be folded downwards (for example as shown at figure 15 (II)) and/or may be un-folded (for example as shown at figure 15 (I)). In some embodiments, movement of frontal/rear portions 1501 may be by one or more actuators, e.g., an electric motor. In some embodiments, the actuator may be connected to the frontal/rear portions 1501 and incline each of frontal/rear portions 1501 at a desired inclination angle.

Referring now to Figure 16 that shows a perspective view of an exemplary segmented seat 1600, according to some embodiments of the invention. In some embodiments, a gap between portions (e.g., portions 1602) of seat 1600 can be modified. Optionally, such modification includes adjustment of the size and/or the shape of the seat in accordance with the user’s size. Optionally, such adjustment can be in accordance with a desired training protocol. For example, if a loose attachment between the pelvis and portions of seat 1600 (e.g., rear or front portions 1601) is required, the gap between the portions (e.g., 1601 and 1602) of seat 1600 can be enlarged and vice versa.

In some embodiments, the gap between portions of seat 1600 as exemplified for example at figure 16 can be modified by inclination of parts of the seat 1600 in relation to each other, as exemplified for example at figure 15.

Referring now to Figure 17, which shows a perspective top view of an exemplary segmented seat 1700, according to some embodiments of the invention. The figure exemplifies the location of portions (e.g., portions 1701 and 1702) of seat 1700 in relation to each other. In some embodiments, portions 1701 and 1702 may be positioned apart from each other. Optionally or alternatively, portions 1701 may be positioned adjacent to each other. Optionally, modification of the distance between two or more portions of seat 1700 is by a joint/ assembly 1703 (illustrated as a cross-hatched cross), poisoned between two or more pars.

Referring now to FIGs. 24A-E show schematic illustrations of a pelvis training system, according to some embodiments of the invention.

Figs. 24A-E show schematic illustrations of portions of a pelvis training system, with more details of a locking mechanism and how an example embodiment locking mechanism works.

Fig. 24A is a cross sectional view from a left side of the pelvis training system, showing: a seat 2401; a flexible connector 2414, connected at one end to the seat 2401, and another end optionally shaped as a ring 2418 surrounding a vertical supporter 2416 2420; and a back stmt 2408, optionally connected to a locking prong 2412. In some embodiments, the vertical supporter 2416 2420 is adjustable in height, with a top portion 2416 of the vertical supporter 2416 2420 extending from a bottom portion 2420 of the vertical supporter.

In some embodiments, the height that the top portion 2416 of the vertical supporter 2416 2420 extends from a bottom portion 2420 of the vertical supporter into the flexible connector 2414, or spring 2414, enables setting a stiffness of the side-to-side and/or the forward-backward swaying of the seat 2401. The more the top portion 2416 of the vertical supporter 2416 2420 extends into the flexible connector 2414, the less length of the flexible connector 2414 is available for bending, the stiffer the resistance to swaying and/or the smaller the angular range available for the seat 2401 to bend from a central position.

In some embodiments, movement of the seat relative to a rest position is against resistance, optionally as provided by the flexible connector described herein, and the springs described herein.

In some embodiments, movement of the seat relative to a base of the seat is against resistance, as provided by the flexible connector described herein, and the springs described herein.

In some embodiments, the resistance is provided by an elastic component, such as a spring. Additional components which are optionally used for resistance to movement optionally include rubber bands, rubber bushings, flat springs, coil springs, and additional elastic components.

In some embodiments, the vertical supporter 2416 2420 comprises several components, such as a top portion 2416 movable up and down relative to a bottom portion 2420, and an optional control, such as the control 2305 shown in FIG. 23A for adjusting an amount by which the top portion 2416 extends from the bottom portion 2420.

In some embodiments, a control such as the control 2305 shown, for example, in Fig. 23A, can serve to set a height that the top portion of the vertical supporter 2416 extends from a bottom portion 2420 of the vertical supporter into the flexible connector 2414, or spring 2414.

Optionally, the flexible connector 2414, or spring 2414, enables the seat 2401 to change angle, relative to the floor or to the device base, so the seat 2401 can move side-to-side and/or forward and back. In some embodiments a range of movement of the seat 2401 is optionally in a range from +10 degrees to -10 degrees. In some embodiments a range of movement of the seat 2401 is optionally in a range from +30 degrees to -30 degrees. In some embodiments a range of movement of the seat 2401 is optionally in a range from +45 degrees to -45 degrees. In some embodiments a range of movement of the seat 2401 is optionally in a range from +60 degrees to - 60 degrees.

In some embodiments, not shown here but which can be understood based on the example described here, the vertical supporter 2416, or at least the top portion of the vertical supporter 2416, is a tube which surrounds the flexible connector 2414. An amount by which the flexible connector 2414 extends from the surrounding vertical supporter 2416 optionally serves to adjust stiffness and/or the range of angular motion of the seat 2401.

The above explanation referring to setting stiffness and/or angular range of swaying is provided here, with reference to Figure 24A, where the relevant components are clearly visible. However, the explanation is intended to apply to embodiments a shown in Figures 20A-C, 21A-C, 22A-C, 23A-C and 24A-E.
