Fig. 3 is a schematic perspective view of a further embodiment of the side cheek according to the invention.

In the drawings, the outer components of the side cheek, in particular a corresponding upholstery part with reference, are omitted for the sake of simplicity. The relevant component of the adjustable side cheek is a bracket 10 , which is arranged to be movable and / or pivotable in a suitable manner.

The bracket 10 can be in the form of a rod, a tube or another elongated profile part and has the shape of an elongated loop with an outer, arcuate region 18 and an inner rectilinear region 16 , the latter being pivotably mounted in one or more pivot bearings 14 ,

This pivoting movement is indicated in Fig. 1 with a double arrow A, the pivoting movement about an axis of rotation 12 which follows it, which extends through the rectilinear region 16 of the bracket 10 .

In the embodiment according to FIGS. 1 and 2, the rotary bearing 14 is located on a bearing block 34 which is carried by a slide 20 . The carriage 20 is formed as a carrier plate, as indicated schematically in FIGS. 1 and 2. The carriage 20 is on opposite sides in profile 28 , conveniently stored U-profiles and moved bar. In Fig. 1 and 2, this displacement of the carriage 20 is indicated with a double arrow B.

In the embodiment according to FIG. 1, eyes 32 are easily seen in the rectilinear region 16 of the bracket 10 at a distance from one another, through which retaining bracket 30 pass. The holding brackets 30 represent additional guides and bearings for the bracket 10 when it is moved upwards with the aid of the slide 20 relative to the position in FIG. 1. The eyes 32 have a sufficient play around the bracket 30 , such that the pivoting movement of the bracket 10 in the direction of the double arrow A is not affected.

In the embodiment according to FIG. 1, the bracket 10 has an arcuate region 26 , on which a spring 42 engages, which in turn is fastened to the slide 20 . The spring 42 is formed in this case as a tension spring, which strikes the bracket 10 with a bias in the direction of the viewer.

At the arcuate portion 18 of the bracket 10 attacks a schematically shown first pulling device 40 , which is guided around a deflection roller 36 in the embodiment shown. The actuation of this first pulling device 40 is indicated by the double arrow C and works against the spring 42 .

If no force is exerted with the first pulling device 40 , the bracket 10 is pivoted out in the maximum direction in the direction of the viewer. Depending on the tractive force exerted by the first traction device 40 , the bow 10 with its arcuate region 18 can then be pivoted away from the viewer.

On the carriage 20 or its bearing block 34 engages a white spring 52 which is attached at its other end to the frame 60 . In this case, the spring 52 is designed as a tension spring, for example as a coil spring.

In another embodiment, not shown, it is also possible to use a compression spring 52 , which then engages on the other side of the frame 20 or the bearing block 34 and is supported on an upper part of the frame 60, not shown.

In Fig. 1 can also be seen schematically shown second pulling devices 50 , which engage in the rectilinear region 16 of the bracket 10 and are guided outwards with the aid of deflection rollers 38 in a manner not shown in detail. The movements of the second traction device 50 are indicated by double arrows D on.

The second pulling devices 50 work against the spring 52 . If no force is exerted with the second pulling devices 50 , the bracket 10 is retracted to the maximum extent, since the spring 52 acts on the straight region 16 of the bracket 10 via the carriage 20 and pulls it downwards in the illustration according to FIG. 1.

Depending on the force exerted by the pulling devices 50 , the bracket 10 can then be pulled upwards out of its illustrated lower position.

Of course, it is not necessary to use two such second pulling devices 50 . It is also sufficient to have a second pulling device 50 , which can act either on the rectilinear region 16 of the bracket 10 or on the slide 20 or its bearing block 34 .

In the embodiment according to FIG. 1, the outer ends of the bracket 10 are bent several times in the manner shown, as is indicated by the reference number 25 . So that the arcuate portion 18 of the bracket 10 can be positioned in a suitable manner opposite the cushion part of the corresponding side cheek. In addition, the stability of the bracket 10 is thus improved ver.

Fig. 3 shows a further embodiment of the side cheek of the invention. In this case, the bracket 10 is formed as a elongated component with an outer arcuate region 18 and an inner rectilinear region 16 , which is rotatably supported by pivot bearings 14 .

The pivot bearings 14 are in this case attached to the carriage 20 itself, which is designed as a carrier plate and has bearing blocks 22 with a U-profile, which lie opposite one another and which encompass a stationary base plate 24 , on which they are displaceably guided.

For reasons of stability, the base plate 24 is profiled out, as is indicated schematically in FIG. 3. In the lower region, the base plate 24 is provided with schematically indicated fastening parts 27 , which are used to mount a corresponding side cheek.

One can also see springs 52 which, on the one hand, engage the frame 60 and, on the other hand, are attached to the slide 20 . These springs 52 are expediently ausgebil det as tension springs which pull the carriage 20 into its maximum retracted position.

A second pulling device 50 , shown schematically in FIG. 3, works against these springs 52 and can pull the bracket 10 mounted on the slide 20 upwards. This shifting movement of the carriage 20 is indicated in Fig. 3 with the double arrow B.

In the embodiment according to FIG. 3, the bracket 10 is provided in the area of the slide 20 with an arcuate or cranked area 26 which detects a crank on the bracket 10 . A spring 42 , which is supported on the slide 20 on the opposite side, acts on this arcuate or cranked region 26 .

In this way, the spring 42 presses the lower region of the bracket 10 away from the viewer, so that the bracket 10 with its arcuate region 18 is pivoted toward the viewer. Thus, the bracket 10 is biased in its initial position, in which it is at a maximum distance from an adjacent seat.

In the embodiment according to FIG. 3, a first pulling device 40 can be seen which engages via a deflection roller 36 on the arcuate or bent portion 26 of the bracket 10 . The movement of this pulling device 40 is indicated in FIG. 3 by the double arrow C and causes the bracket 10 to pivot about its axis of rotation 12 . This pivoting movement is indicated in FIG. 3 by the double arrow A.

Furthermore, a second pulling device 50 can be seen in FIG. 3, which acts on the slide 20 via a deflection roller 38 . The actuation of this second pull device 50 is indicated by the double arrow D. It causes a displacement of the slide 20 in the manner indicated by the double arrow B in FIG. 3.

The pulling devices 40 and 50 are expediently designed as Bowden cables with which the movements of the bracket 10 can be controlled in both directions. If a train is exercised with the Bowden cables, this works against the respective springs 42 and 52 . If the Bowden cable is actuated in the opposite direction, the movement is supported by the respective springs 42 and 52 .

Such Bowden cables are expediently actuated by drives not shown, in particular servomotors, in order to bring the bracket 10 into its desired position.

In a seat which is equipped with a symmetrically designed pair of side cheeks, the side cheeks or their brackets 10 are expediently controlled synchronously, such that such a pair of side cheeks are extended or retracted synchronously and / or synchronously with one another or from one another is moved away.

As already indicated, both in a vehicle seat the seat part as well as the backrest with a pair of Sei be equipped with the respective pairs of Sidewalls can then be controlled synchronously independently of one another are.  

In the above-described embodiments, the lateral movement of the side cheek as a swivel movement provided, however, the invention is not on such construction shape limited. Rather, the respective bracket in The transverse direction of a seat can also be moved linearly for example in appropriate slide guides. It is also possible Lich, another slide for each side cheek use, the two slides then in two vertically working with each other.

In the illustrated embodiments, the springs 42 and 52 are provided so that they pivot the bracket into its wide open position or pull the carriage into its retracted position. Alternatively, it is also possible to provide the preloads in such a way that the starting positions of the bracket are a pivoted-in position or a maximum-extended position, the pulling devices then working in the corresponding opposite direction. The number of setting options is retained in both cases.
