Detailed ways

Figure 1 shows an embodiment of a bracket 1 for a motor vehicle according to the invention. The bracket 1 has a height adjustment device 6 by which the height position of the placement device 2 can be adjusted. The stowage device 2 can form, for example, an arm support 8 for a vehicle occupant or for the driver.

The height adjustment device 6 here includes four supporting legs 7 which, as can be seen in FIG. 1 , are arranged offset from each other in two structurally identical pairs. The supporting legs 7 are respectively connected to the placing device 2 via the hanging portion 4 . Furthermore, the support legs 7 carry the placement device 4 on the base element 10 in that the support legs 7 are each connected to the base element 10 via a support point.

In addition, the suspensions 4 of the bracket 1 shown here each simultaneously form the axis of rotation of the gear wheel 12 . In particular, the two gearwheels 12 are each engaged into each other and form a transmission. Therefore, according to the invention, the coupling of the supporting legs 7 is achieved, so that the rotational movement of the first supporting leg 7 can be transmitted to the further supporting legs 7 by means of the transmission mechanism or gear 12 .

As can also be seen from FIG. 1 , one pair of structurally identical pairs of support legs 7 can be guided movably along the guide rail 16 . Here, in this embodiment, the other pair of support legs 7 is arranged only pivotably and immovably at corresponding support points on the base element 10 .

Furthermore, two operating elements 15 can be seen in FIG. 1 . In this case, the actuating element 15 is mechanically coupled to a locking device which is designed to releasably lock the rotational movement of at least one support leg 7 and thereby secure the setting of the distance between the suspension 4 and the base element 10 , so that the bracket 1 is fixed in its position. Actuating at least one actuating element 15 , in particular by a vehicle occupant, can cause the set locking or release the locking, so that the position of the carrier 1 can be adjusted again.

Furthermore, FIG. 1 shows a mobile unit 14 which, in this embodiment, is arranged below the base element 10 and allows the base element 10 to be parallel to the resting device 2 or bracket 1 relative to the mobile unit 14 . Move in the longitudinal extension direction. Thus, in addition to the high degree of mobility according to the invention, the carriage 1 allows in particular a longitudinal movement of the carriage 1 by means of the movement unit 14 .

In addition, a first storage element 31 and a further storage element 3 can be seen in FIG. 1 , which can be used by the vehicle occupant or the driver to store or use objects. . The first resting element 31 is here directly connected to the resting device 2 . The barrier element 9 projects from this first rest element 31 , the rest element 3 being received in the recess 18 of the barrier element 9 , and the barrier element 9 being configured as a further rest element 3 . In this embodiment, the first resting element 31 simultaneously forms a rotary support arrangement 5 , via which the blocking element 9 and the resting element 3 accommodated therein can be moved around a vertical axis extending through the first resting element 31 . Direct axis A pivots.

This embodiment is shown in side view in FIG. 2 . In this view, an exemplary substantially horizontal orientation in the drawing plane of the resting device 2 , the first resting element 31 as well as the lining element 9 and the resting element 3 accommodated therein becomes apparent.

FIG. 3 shows the same side view as in FIG. 2 , wherein the resting device 2 is shown inclined about the axis of rotation B compared to the horizontal orientation in FIG. 2 . This exemplary tilting can be achieved by elastic elements 13 respectively arranged at the individual support legs 7 . In this embodiment, the support leg 7 on the left as viewed in the drawing plane has an elastic element 13 . The support leg 7 with the elastic element 13 is configured in such a way that a force directed vertically downwards in the drawing plane acts on the resting device 2 , for example when a vehicle occupant supports his or her forearm on the resting device 2 or on the arm support. 8, these supporting legs 7 shorten under the elastic action of the elastic element 13, wherein the inclination of the resting device 2 is set by the rotation of the gear 13 and the pivoting movement of the supporting legs 7. In this exemplary embodiment, the axis of rotation B of the resting device 2 is located approximately in the engagement region of the pairs of gear wheels 12 that engage one another.

At the same time, the support leg 7 , which is guided or guideable on the guide rail 16 , can be moved along its guide rail 16 . By means of such a displacement movement, the angle between the pairs of supporting legs 7 can be changed, which advantageously means further adjustment possibilities for the inclination and height position of the resting device 2 .

When the resting device 2 in FIG. 2 is tilted relative to the horizontal, the first resting element 31 directly connected to the resting device 2 and the blocking element 9 continue to be oriented horizontally with the resting element 3 accommodated therein. For this purpose, the storage device 2 and the first storage element 31 are connected in an articulated manner.

FIG. 3 also schematically shows the position of the storage device 2 which is displaced longitudinally by means of the displacement device 10 relative to the position in FIG. 2 .

FIG. 4 shows a perspective view of the carrier 1 according to this embodiment, in which the lining element 9 and the resting element 3 that can be accommodated in the receptacle 18 of the lining element 9 are shown in an exemplary embodiment similar to FIG. 1 is shown in a position pivoted about the vertical axis A of the first resting element 31 . By pivoting, the resting element 3 or the lining element 9 can advantageously be pivoted independently of each other towards or away from the vehicle occupant when required for the use of the vehicle occupant. This pivoting is achieved here by the pivoting support device 5 formed by the first resting element 31 . In this exemplary embodiment, the barrier element 9 is furthermore designed to be tiltable such that the upper region of the barrier element 9 is tilted out to release the two surface elements 21 , 22 which are in this way. The folded-out position advantageously provides an increased support area for placing or using objects compared to the folded-in position shown in FIG. 1 . If the surface elements 21 , 22 are not required, these can be folded back in and thus stored with an advantageously small space requirement.

FIG. 5 shows a side view of the carriage 1 from FIGS. 2 and 3 , in which the first resting element 31 is tilted about the tilt axis C compared to the position shown in FIGS. 2 and 3 . In order to achieve this tilting movement independently of the tilt of the resting device 2 , the first resting element 31 and the resting device 2 can be connected in an articulated manner. At the same time, the first resting element 31 furthermore enables pivoting of the lining element 9 and the resting element 3 accommodated therein, which are shown here in an exemplary position. In this position, since the first resting element 31 is tilted, the lining element 9 and the resting element 3 accommodated therein are accordingly tilted about the tilt axis C. In particular, by tilting the first resting element 31 , the lining element 9 or the resting element accommodated therein can also be tilted. This is advantageous in particular for an orientation of reading material such as magazines, books or by means of a screen on the lining element 9 or the storage element 3 in relation to the vehicle occupants, which is perceived as pleasant by the vehicle occupants.
