Description

This invention relates to a motorized active chair mechanism.

In office chairs, train / plane chairs and some other chairs, it is possible to adjust the backrest and seat height manually.

Current office chairs or train / airplane chairs are ergonomically either too low or too short for the seat in terms of seat base depth. Their height adjustment is not enough for the required height. They cause unwanted extra muscle tension that has effects on the well-being of the entire body.

With regard to active chairs, it is known that there is a seat that indicates when the weight of the occupant is at a certain point in the body. The occupant is thus instructed to change his position. The position of the seat base of the chair does not change, so that the muscles of the seater also remain in a static load state at all times.

With the help of the motorized active chair mechanism and by increasing the seat height with the help of the adjustable support leg, a seat position that activates several individual muscles / muscle groups, but at the same time consumes less body, is achieved.

Based on my test, it has been found that by using a motorized active chair mechanism as well as designing the chair higher, the sitting position of the occupant becomes substantially less muscular. At the same time, more muscles and muscle groups are activated, so that the load caused by weight is more evenly distributed to the muscles. The use of deep muscles, ie previously unused muscles, as well as entire muscle groups, is diversifying. This is due to a change in the center of gravity of the body. By loading more muscles and groups of muscles more evenly as the movement of the seat changes, better blood circulation is achieved for the occupant, posture is improved, back loosening and muscle numbness is prevented. As a result, the posture of the occupant also improves and the work becomes more efficient. The structure of the chair is designed to activate the muscles of the occupant both during sitting and to maintain the body's natural physical performance after sitting.

The active chair mechanism can also be used to help patients in need of physical treatment, the functionality of which has been verified by a Finnish physiotherapist.

The invention will now be described in more detail with reference to the accompanying drawings, which show the functionality of the active chair mechanism as a whole.

Seat assembly

The structure of the motorized active chair mechanism consists of a steel support leg (7) fixed to the mounting base, the upper end of which has a cup-shaped part into which a ball head (3) enabling rotational movement is integrated. As a whole, the cup part and the ball head are made of hard plastic, aluminum or stainless steel. The upper part of the ball head is attached to the seat part (8).

The support leg (7) has 2-3 spindle motors (1,2) attached. The upper ends of the motors are attached to small ball heads (4) which are attached to the seat part (8). By applying the electrically generated movement of the spindle motors to the seat part (8), the seat can be moved either forward or backward, to the right or to the left, controlled by another person or controlled by the occupant himself.

Ball head mounting base (Figures 3 and 4)

The ball head mounting base consists of three subassemblies that are attached to each other. The ball head (3) is placed in a two-part bracket (10) which is attached to the mounting plates (11). The two mounting plates are attached to the support leg (7).

LIST OF IMAGES

The invention will now be described in detail with reference to the accompanying drawings, in which Figure 1 shows parts of a motorized active chair mechanism with a motorized active chair mechanism according to the invention. Figure 2 shows a single direction of movement of the motors of Figure 1. Figure 4 shows the attachment points of the support base

Seated Manual

The mechanism built into the motorized active chair is based on motorized units, a transformer and a remote control, which allow the user to change the position of the seat himself at certain intervals by means of a control unit (5).

Programmed Programmed

The operation of the motorized active chair mechanism can also be operated by means of a programmed Arduino control (6), in which the chair moves automatically at certain intervals.

Alternative embodiments of the invention

All directions of movement at 360 degrees allow for more versatile seating positions. This can be done by means of a slide rail mechanism which can be connected under the ball head (3) and the seat part (8).

Programmed APP

Through the phone, a notice of too long the same sitting time, when the chair changes position or tells you to move. The phone summarizes the activity of the muscles and creates a so-called an exercise program that needs to be changed while sitting in the future. In this way, through a more concrete way, a person learns to take more care of the time spent sitting.

Connection: via Bluetooth or WLAN or USB via phone and remote control in the seat.

Seated APP

You can use your phone to create an active program while sitting. Change of direction of movement, massage cushions placed in the chair, which are activated when the position changes -> massage.
