Abstract

The invention relates to a seat device, which similarly to a rocking chair allows the user to be actively or semi-actively moved in a rocking manner in the resting position. By suspending or supporting a seat pan according to the invention in a movable manner such that in this way a movement of the seat pan about a substantially invariant point of the center of the user's body, which typically is found in the abdominal region, is achieved, it is ensured that also the user is moved substantially about the center of the body thereof, which is to say that the extremities oscillate or swing about said center of the body. In this way, a particularly relaxed and pleasant effect for the user is achieved.

Description

S I T Z V O R R I C H T U N G

The invention relates to a seat device with a seat surface and a backrest, which complement each other to a seat shell, which is movably mounted and / or suspended.

Such a seat device is previously known from Japanese Laid-Open Publication 7-275073. There, a chair is proposed, which has a recessed surface portion in a base member, in which a projecting ball ^¬ shaped surface with the interposition of bearing balls engaged such that the attached seat shell for exporting ^¬ tion spherical movement is displaceably mounted.

Another, rotatably mounted seat device is previously known for example from US 696,239. This is a more or less conventionally-shaped chair with a backrest and a seat surface, and two on both sides being ^¬ arranged armrest, wherein the seat is associated with a sub-structure, as it is not known when a shop ^¬ kelstuhl usually. It is deliberately dispensed with the curved rocker elements and instead uses a specially ge ^¬ led handlebar assembly to achieve improved mobility of ^¬ mobility of the chair.

Alternatively, a complex support structure for a seat device from WO 00/40121 Al is already known, wherein the support structure consists of four spaced-apart vertical supports which span a square and connected to each other and held by a holding device arranged below the actual seat device. At the four support ears thus arranged, a seat surface with its respective four corners corresponding tethers auf- hangs, wherein two adjacent tethers are additionally connected to a serving as a backrest further plate, which are arranged at least approximately perpendicular to the horizontally suspended seat surface.

Based on the correct finding that the human body is not created to sit still and it is therefore advantageous to provide movement even during rest and recovery phases of the musculature, with the previously known from WO 00/40121 Al seat device is a relative moderately unstable seat device created in which the mobility is undoubtedly made safe by the seat ^¬ construction is flexible and unstable. This also illustrates the disadvantage, since thereby the seat comfort appears clearly limited and it appears also not excluded that the backrest knocking down at unge ^¬ schickter movement and the user falls through the far open space between the seat and backrest downward. The sitting pleasure seems to be very limited here.

Also, from WO 98/15382 Al is starting from the same

Awareness that it would be useful to put the body in motion to stimulate the senses and muscles, a device for the spatial movement of bodies, preferably human bodies known. This is a Vorrich- tung, wherein the body can be pivoted about three axes X, Y and Z in the space, wherein the extent denote ^¬ th axes of rotation intersect each other in the body center. Here, however, the "moving" person standing in front of ^¬ direction to take, so that the device has to realize a substantial chen space requirement and mechanical effort to provide the appropriate body movement. The in described international application appears at best suitable for the medical field.

Finally, from WO 86/06597 a special pendulum is known, which can be used for holding seat devices, but at least for holding a backrest, the pendulum is doing with a variety of bead-like, relatively rigid bodies, with only a small distance from each other bead-like distributed over the length of the pendulum ^¬ are arranged, designed. It is therefore a spine-like arrangement that is to be used for sitting or rest furniture.

This is the dormant or sleeper each a piece of furniture with mobile momentum to be offered.

Based on this prior art, the present invention seeks to provide a chair in which the body can rest in a gentle motion, this being to be realized by a spherical or rocking movement of the seat, in which the body to the, about located in the abdominal region, swinging around the body center, so this body center is essentially resting, while the forte extending limbs are moved by the dynamic piece of furniture.

Such movement around the body center is apt to induce particularly pleasant relaxation and comfort for the particular user of the respective seating device.

The object underlying the invention is achieved with a seat device according to the main claim. Advantageous ^{embodiments of} this seat device can be taken from the dependent claims. The solution of the problem is achieved in that a seat is mounted so movable that it is ensured due to the special storage or suspension of the seat that the fulcrum mediated by the movable storage or suspension movement is always in the body center of a person intended in the seat resumed ^{¬ is} orders.

In this case, according to a first embodiment, the seat shell via at least two, the backrest U-shaped orbiting side supports to be held while the seat of the seat is suspended via two each arranged on both sides tethers pendulum on the side supports. The Seitstützen as such are in turn connected by its apex from rotating ^¬ articulated manner to a holding tube, which ensures that the suspension of the seat shell approximately at the level of the body centering ^¬ rums of the person intended received in the seat shell is arranged.

In order to enable a better adaptation of the seat device to the respective user, it has proved to be advantageous if the pivot connection of the side supports with the holding tube is arranged to be longitudinally movable along the holding tube. In this way it can be ensured that the side supports are fastened to the holding tube in each case in the individual height of the respective body center of the respective user.

In order to store the seat stable, it has proven useful if the holding tube, at least approximately, is bent in an S-shape, so that the holding tube opens below the seat in a center of gravity of the seat assembly arranged Aufstellpunkt. However, a second embodiment may provide that a central supporting arm is used instead of a structure with two Seitstützen on which the seat pan Example ^¬ as received with its seat area centers. Also, such a support arm is pivotally connected to the holding tube, so that a lateral rocking is possible.

In this embodiment, advantageously, the holding tube can also describe a circular arc, so that a lower seating position is possible than with an S-shaped bend of the ear tube. Then, the support arm may have a fitted circular arc shape, which should however have a smaller radius than the bending of the holding tube.

Such a support arm carries the seat surface, which in turn is advantageously arranged longitudinally displaceably on the support arm, so that there is also a degree of freedom in this regard. By appropriate movements of the person sitting on the seat apparatus then the seat can be pushed up or down on the support arm, wherein the inclination of the same changes due to the circular arc shape of the support arm depending on the position.

A third variant then provides that the seat shell has under its seat at least one, preferably two, arcuate skids, which are each slidably received in a guide. These guides can then be connected to a further arcuate skid, which is arranged transversely to the first skids. As a result, an arcuate sliding of the seat shell can take place around the center of the arc, and this in the direction of the first skids and / or in the direction of the second skids. A swing around the center of the arc, which advantageously is arranged in the body's center of gravity of a seated in the seat ^¬ nen person is thus made possible.

In a further embodiment of these variants of the seat device is conventional swivel chair constructions in which the holding tube is received in a Aufstellpunkt verbrei ^¬ ternden foot construction. By appropriate side arms with wheels, the foot construction is radially widened and realized by means of the wheels a swivel chair function of the seat device.

In a further embodiment of this swivel chair solution, the holding tube is rotatably received about its longitudinal axis in the foot construction, so that it is possible, as in a swivel chair, for the respective user to rotate the seat relative to the set-up.

In a further embodiment, the holding tube can also be designed to be height-adjustable. This is another Mög ^¬ friendliness, adjust the seat device to the body size of the user.

In order to allow the pendulum of the seat relative to the side supports, it has proved useful if the

Side supports are pivotally connected to the tethers. Here, too, the pivot of the pivotal movements remains in each case, at least approximately, in the center of the body received in the seat ^¬ cup user.

In a final alternative embodiment, which is significantly more complex but design-technically demanding, the seat can also be connected to two each arranged on both sides Trag ^¬ foot pairs in the region of the backrest and the seat, wherein all Tragfußpaare are each connected to Laufrä- countries, the in each case on both sides of the rail arranged parallel and spherically curved rails run. By the movement of the wheels in the spherically curved rails a conventional rocking motion is first realized. In addition, however, this rail construction is connected by means of other wheels with a fixedly arranged floor rail construction by the rails of the first rail construction are in turn connected to other wheels which are movable in the fixed, each arranged in parallel and also spherically curved rails of the ground rail construction. The rails of the floor slide ^¬ nenkonstruktion are also spherically curved, each arranged orthogonal to the rails of the movable first rail construction.

This elaborate design allows the result dreidi ^¬ dimensional movements of the person sitting in the seat each to the body center of this person.

This is ensured, in particular, by the fact that the imaginary extensions of the longitudinal axes of the support foot pairs connected to the seat shell intersect, at least approximately, in the body center of a person intentionally seated in the seat shell.

The invention will be explained in more detail below with reference to two exemplary embodiments shown only schematically in the drawing.

Show it:

1 shows a swivel-like design Sitzvorrich ^¬ tung in a side view; FIG. 2 shows an alternative embodiment of a chair-type seat device in a perspective view, and FIG

Figure 3 shows a further alternative embodiment of a chair-like chair device in a perspective view.

As shown in Fig. 1, the seat apparatus essentially consists of a seat pan 1 with a backrest 2 and 3. a seat The seat 3 is via two tethers 4,4 ', each with a Seitstütze 5 rotating ^¬ hingedly connected. The side supports 5 are, not visible from Fig. 1, formed such that they surround the backrest 2 U-shaped and the apex of the U-shape of the side supports 5 on its side facing away from the seat 1 side are connected to a holding tube 6 of the seat device. The articulated connection of the side supports 5 with the holding tube 6 via a longitudinally displaceable sleeve 7, which surrounds the Hal ^¬ terohr 6 in the connection point of the side support 5. The side supports 5 are each pivotally connected to the holding tube 6.

The holding tube 6 is at least substantially S-shaped bent such that it opens at the end facing away from the seat 3 end in a base construction 10 as intended, which represents a conventional Drehstuhlfußanordnung here. It consists essentially of several star-shaped

Side arms 11, which, not shown here, by means of wheels 15 of the side arms 11 in turn could be moved. The holding tube 6 is rotatably received in a receiving socket 12. In the receiving socket 12, in addition to the height adjustment of the holding tube 6 and thus also the seat 1 may be arranged a gas spring, to disengage the holding tube 6 upwards accordingly.

The pivotal suspension of the seat 3 over the Hal ^¬ teseile 4,4 'and the pivotal connection of Sitzscha- Ie 1 with the holding tube 6 allows rotation of the body of the intended purpose in the seat 1 person to two mutually orthogonal axes of rotation, each both, at least approximately intersect at the body center of each ^¬ weiligen person, so allowing a pivoting of the person to the body center of gravity.

Figure 2 shows a variant of this seat device, which instead of a U-shaped, the seat pan 1 embracing side support 5 a single, the seat shell 1 and also connected drehgelenkig verbunde with the holding tube 6 nen support arm 9, on which the seat 1 with egg ^¬ ner is secured by punctiform connection means not shown here almost punctiform. The connecting means las ^¬ sen while a displacement of the seat 1 on the support arm 9 to, in which the mounting bracket is always kept constant and hence the seat 1 9 executes a tilting motion due to the arcuate configuration of the support arm 9 in its movement along said support arm. However, in order to obtain a defined seating position, the seat pan 1 can also be fixed in relation to its position relative to the support arm 9.

By this construction, a swinging movement is also possible in the lateral direction and a tilting movement forward and backward, the latter being superimposed with a height adjustment. The other swivel chair elements in the foot construction correspond to the embodiment of FIG. 1. Figure 3 shows a further variant in which each is ^¬ but dispensed rotation about an ending in the region of the backrest holding tube 2. 6 Rather, an oscillating movement is made possible by arcuate skids 13, 14, wherein two first arcuate skids 13 are arranged directly below the seating surface 3 and a second arcuate skid blade is arranged transversely thereto. In the arch region of these runners 13,14 are positioned ^¬ taken respectively in guides 15,16, so nen this to slide along its arc portions kön-. First guides 15 are connected to the ends of the second skid and a second guide receives the second skid while being centrally located below the seat 3 with the support tube. Thus, on the first skids 13 a swinging movement in the forward direction, on the second skid 14 a swinging movement in lateral

Direction allows. Again, a common foot construction is provided under the seat.

Thus, different versions of it ^¬ invention are described above, without the solution of the invention is limited to those precise embodiments. Alleli ^¬ chen versions have in common that they each represent a seating device that allows the respective user to be actively or half actively moved around a point arranged substantially in the body center of the respective user of the seat device point by dimensioning the corresponding moving device parts and arranged so that the movement made possible so far essentially takes place around the body center.
