Drive device for a motor vehicle swivel seat
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.
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.
