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, the at least one connecting means constructed as at least one screw connecting means and the at least one screw connecting means has a thread-free shaft for the formation of at least one rotation axis; and

at least one actuating arrangement rotatable about the at least one rotation axis for actuating the detent fitting arrangement, the at least one actuating arrangement having a gear which is rotatable about the at least one rotation axis, the gear having a lever unit, which is mounted by a first end rotatably about the at least one rotation axis, the lever unit having a second end with a grip part and the gear having a cam, which is connected at a first end in a torque-proof manner with the lever unit,

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

2. The adjusting device according to claim 1, wherein the cam has a rolling part, in order to roll along the detent fitting lever.

3. The adjusting device according to claim 2, wherein the detent fitting lever has a rolling surface corresponding to the rolling part.

4. The adjusting device according to claim 3, wherein the detent fitting lever is pre-stressed, so that it is able to be moved back into an initial position.

5. The adjusting device according to claim 4, wherein the at least one actuating arrangement has a movement limitation, in order to limit its movement.

6. 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, the at least one connecting means constructed as at least one screw connecting means and the at least one screw connecting means has a thread-free shaft for the formation of at least one rotation axis; and

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

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

7. The motor vehicle seat according to claim 6, wherein the gear has a lever unit, which is mounted by a first end rotatably about the at least one rotation axis.

8. 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, the at least one connecting means constructed as at least one screw connecting means and the at least one screw connecting means has a thread-free shaft for the formation of at least one rotation axis; and

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

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

9. The motor vehicle according to claim 8, wherein the gear has a lever unit, which is mounted by a first end rotatably about the at least one rotation axis.

10. 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, the connecting means constructed as a screw connecting means and the screw connecting means has a thread-free shaft for the formation of a rotation axis;

forming the rotation axis for the rotatable arranging of an actuating arrangement for actuating the detent fitting arrangement about the rotation axis, the actuating arrangement having a gear which is rotatable about the rotation axis and 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,

wherein the rotation axis is constructed in an integrated manner with the connecting means.
