Abstract

A motor vehicle, a vehicle seat for a motor vehicle, and a drive device are provided for swiveling-in and swiveling-out a vehicle seat that is swivelable about a substantially vertical axis, in particular for a front motor vehicle seat which is connected to a motor vehicle by means of a rotary frame. The drive device includes, but is not limited to a first drive unit that applies a driving force for causing a swiveling movement of the seat in at least one swiveling direction. A second drive unit is provided which acts against the first drive unit to provide a second driving force which acts simultaneously against the driving force of the first drive unit, which second driving force causes a second swiveling movement of the vehicle seat.

Claims

1. A drive device for swiveling-in and swiveling-out a vehicle seat that is swivelable about a substantially vertical axis, the drive device comprising:

a first drive unit adapted to apply a first driving force for causing a swiveling movement of the vehicle seat in a swiveling direction; and

a second drive unit adapted to act against the first drive unit and provide a second driving force which acts substantially simultaneously against the first driving force such that the second driving force causes a second swiveling movement of the vehicle seat, wherein the first drive unit and the second drive unit are coupled in such a manner to substantially cancel each other out in a neutral position between a first end position and a second end position.

2. The drive device according to claim 1, wherein the first drive unit is adapted to causes a swiveling from the first end position to the neutral position.

3. The drive device according to claim 1, wherein the second drive unit causes a swiveling from the second end position to the neutral position.

4. The drive device according to claim 1, wherein at least one of the first drive unit and the second drive unit is configured as a spring-storage-unit.

5. The drive device according to claim 4, wherein the spring-storage-unit releases energy during the swiveling from a first end position into a neutral position, and releases energy during the swiveling from the neutral position into a second end position.

6. The drive device according to claim 1, wherein the first drive unit comprises a latching device for locking the vehicle seat.

7. The drive device according to claim 6, wherein the latching device is coupled with a motor vehicle so that the latching device locks depending on a state of the motor vehicle.

8. A vehicle seat of a motor vehicle that is swivelable about a substantially vertical axis, comprising:

a rotary frame;

a seat device connected to the motor vehicle with the rotary frame;

a first drive unit adapted to apply a first driving force for causing a swiveling movement of the vehicle seat in a swiveling direction; and

a second drive unit adapted to act against the first drive unit and provide a second driving force which acts substantially simultaneously against the first driving force such that the second driving force causes a second swiveling movement of the vehicle seat, wherein the first drive unit and the second drive unit are coupled in such a manner to substantially cancel each other out in a neutral position between a first end position and a second end position.

9. The vehicle seat according to claim 8, wherein the first drive unit is adapted to causes a swiveling from the first end position to the neutral position.

10. The vehicle seat according to claim 8, wherein the second drive unit causes a swiveling from the second end position to the neutral position.

11. The vehicle seat according to claim 8, wherein at least one of the first drive unit and the second drive unit is configured as a spring-storage-unit.

12. The vehicle seat according to claim 11, wherein the spring-storage-unit releases energy during the swiveling from a first end position into a neutral position, and releases energy during the swiveling from the neutral position into a second end position.

13. The vehicle seat according to claim 8, wherein the first drive unit comprises a latching device for locking the vehicle seat.

14. The vehicle seat according to claim 13, wherein the latching device is coupled with the motor vehicle so that the latching device locks depending on a state of the motor vehicle.
