Abstract

A motor vehicle includes a vehicle body, a drive motor, particularly an electric motor and/or a combustion engine, a seat with a frame, and a mechanism for adjusting the height of the seat. The mechanism includes a front lever and a rear lever, each fixed in articulated manner to the frame via an upper articulated joint and to a retaining structure via a lower articulated joint so that swiveling of the front and rear levers causes a height adjustment of the seat. An actuator affects motorized adjustment of the seat height. An auxiliary mechanism supplements the front and rear levers such that a force, particularly a turning moment, applied to the auxiliary mechanism by the actuator adjust the height of the seat.

Claims

1. -15. (canceled)

16. A motor vehicle comprising:

a vehicle body;

a seat with a frame supported within the vehicle body;

a first mechanism operably coupled between the seat and the vehicle body, the first mechanism including a front lever and a rear lever, each fixed in articulated manner via an upper articulated joint to the frame and via a lower articulated joint to a retaining structure,

a second mechanism operably coupled between the seat and the vehicle body;

an actuator configured to apply a turning moment to at least one of the first and second mechanisms for adjusting a height of the seat relative to the vehicle body.

17. The motor vehicle according to claim 16, wherein the actuator is configured to apply the turning moment for adjusting the height of the seat exclusively to the second mechanism.

18. The motor vehicle according to claim 16, further comprising a gearbox mechanically connected to the actuator, wherein the turning moment is transmitted from the actuator to the second mechanism via the gearbox.

19. The motor vehicle according to claim 18, wherein the actuator and the gearbox are fixed on the second mechanism.

20. The motor vehicle according to claim 16, wherein the second mechanism comprises a first lever fixed to the frame via a second upper articulated joint, and a second lever is fixed to the retaining structure via a second lower articulated joint, wherein the first and second levers are connected in articulated manner to each other via a connecting articulated joint.

21. The motor vehicle according to claim 20, further comprising a gearbox mechanically connected to the actuator, wherein the turning moment is transmitted from the actuator to the second mechanism via the gearbox.

22. The motor vehicle according to claim 21, wherein the actuator and the gearbox are fixed on at least one of the first or second levers.

23. The motor vehicle according to claims 21, wherein the actuator and the gearbox are fixed on the first lever, and a toothed rack is fixed on the second lever, and a gearwheel on the gearbox meshes with the toothed rack to transmit the turning moment.

24. The motor vehicle according to claim 23, wherein the toothed rack comprises a curved toothed rack having a center point that is coaxial with a swivel axis of the connecting articulated joint.

25. The motor vehicle according to claim 16, wherein the seat further comprises an upholstery element and the kinematics of the second mechanism is configured such that a distance between the actuators and the upholstery element is substantially constant.

26. The motor vehicle according to claim 16, wherein the actuator is arranged in the area of an inner side of the frame.

27. The motor vehicle according to claim 26, wherein the frame comprises two side members and the actuator is arranged therebetween.

28. The motor vehicle according to claim 16, wherein the actuator comprises an electric motor.

29. The motor vehicle according to claim 16, wherein the seat further comprises two rails and the retaining structure is supported on a carriage to be movable in a longitudinal direction in the rails.

30. The motor vehicle according to claim 16, further comprising a seatbelt for the seat and a belt buckle for the seatbelt releasably secured to the frame.

31. The motor vehicle according to claim 16, wherein the first mechanism comprises two front levers and two rear levers.
