Abstract

A motor vehicle including a motor vehicle seat with an adjusting device for the multiple adjusting of a motor vehicle seat is provided. In one example, a backrest adjusting device with a discontinuous detent fitting arrangement for adjusting a backrest part relative to a sitting part, including a detent fitting arrangement connected in a stationary manner with the sitting part via connecting means, and at least one actuating arrangement rotatable about at least one rotation axis for actuating the detent fitting arrangement is provided. The at least one rotation axis is constructed in an integrated manner with at least one of the connecting means, and a method for this is provided.

Claims

1. An adjusting device for multiple adjusting of a backrest part relative to a sitting part of a motor vehicle seat, comprising:

a discontinuous detent fitting arrangement connected in a stationary manner with the sitting part via at least one connecting means; and

at least one actuating arrangement rotatable about at least one rotation axis for actuating the detent fitting arrangement,

wherein the at least one rotation axis is constructed in an integrated manner with at least one of the connecting means.

2. The adjusting device according to claim 1, wherein the at least one connecting means is constructed as at least one screw connecting means.

3. The adjusting device according to claim 2, wherein the at least one screw connecting means has a thread-free shaft for the formation of the at least one rotation axis.

4. The adjusting device according to claim 3, wherein the at least one actuating arrangement has a gear which is rotatable about the at least one rotation axis.

5. The adjusting device according to claim 4, wherein the gear has a lever unit, which is mounted by a first end rotatably about the at least one rotation axis.

6. The adjusting device according to claim 5, wherein the lever unit has a second end with a grip part.

7. The adjusting device according to claim 6, wherein the gear has a cam, which is connected at a first end in a torque-proof manner with the lever unit.

8. The adjusting device according to claim 7, wherein the gear has a detent fitting lever, rotatable about a detent fitting axis, in order to rotate the detent fitting axis via the detent fitting lever and to release or to lock the detent fitting arrangement.

9. The adjusting device according to claim 8, wherein the cam has a rolling part, in order to roll along the detent fitting lever.

10. The adjusting device according to claim 9, wherein the detent fitting lever has a rolling surface corresponding to the rolling part.

11. The adjusting device according to claim 10, wherein the detent fitting lever is pre-stressed, so that it is able to be moved back into an initial position.

12. The adjusting device according to claim 11, wherein the at least one actuating arrangement has a movement limitation, in order to limit its movement.

13. A motor vehicle seat, comprising:

an adjustable sitting part; and

a backrest part which is adjustable with respect to the sitting part, including at least one adjusting arrangement for adjusting at least one of the backrest part and the sitting part, the adjusting arrangement including;

a discontinuous detent fitting arrangement connected in a stationary manner with the sitting part via at least one connecting means; and

at least one actuating arrangement rotatable about at least one rotation axis for actuating the detent fitting arrangement, the at least one actuating arrangement having a movement limitation to limit its movement,

wherein the at least one rotation axis is constructed in an integrated manner with at least one of the connecting means.

14. The motor vehicle seat according to claim 13, wherein the at least one connecting means is constructed as at least one screw connecting means.

15. The motor vehicle seat according to claim 14, wherein the at least one screw connecting means has a thread-free shaft for the formation of the at least one rotation axis.

16. The motor vehicle seat according to claim 15, wherein the at least one actuating arrangement has a gear which is rotatable about the at least one rotation axis.

17. The motor vehicle seat according to claim 16, wherein the gear has a lever unit, which is mounted by a first end rotatably about the at least one rotation axis.

18. A motor vehicle, comprising:

a motor vehicle seat having an adjustable sitting part, a backrest part which is adjustable with respect to the sitting part, and at least one adjusting arrangement for adjusting at least one of the backrest part and the sitting part, the adjusting arrangement including;

a discontinuous detent fitting arrangement connected in a stationary manner with the sitting part via at least one connecting means; and

at least one actuating arrangement including a gear which is rotatable about at least one rotation axis for actuating the detent fitting arrangement,

wherein the at least one rotation axis is constructed in an integrated manner with at least one of the connecting means

19. The motor vehicle according to claim 18, wherein the gear has a lever unit, which is mounted by a first end rotatably about the at least one rotation axis.

20. A method for mounting a motor vehicle seat with a backrest adjusting device with a discontinuous detent fitting arrangement for the multiple adjusting of a backrest part relative to a sitting part of the motor vehicle seat, comprising:

connecting the detent fitting arrangement with the sitting part via connecting means, so that the detent fitting arrangement is connected in a stationary manner with the sitting part;

forming a rotation axis for the rotatable arranging of an actuating arrangement for actuating the detent fitting arrangement about the rotation axis,

wherein the rotation axis is constructed in an integrated manner with at least one of the connecting means.
