Abstract: A drive system (2) tilt adjusts a back rest (10) of a vehicle seat (1). The back rest (10) is held on a seat base (11) by a fitting (12). An output pinion (24), drivable by a drive motor (20), is provided on the seat back side and interacts with a tooth segment (18) arranged rotationally fixed on the base (11). A pivot movement of the back rest (10) can be carried out by the drive motor (20) while the fitting (12) is unlocked. The output pinion (24) can be uncoupled from the drive motor (20) by a coupling (22). A compensation spring (14) acting between the back rest (10) and the base (11) pre-tensions the back rest (10) in the direction of the non-use position. A vehicle seat (1) with the drive system and a method for operating a drive system (2) are also provided.

Abstract: An adjustment unit for a vehicle seat in a vehicle is disclosed. Said adjustment unit comprises a longitudinal adjustment mechanism for adjusting the vehicle seat along a direction of travel of the vehicle, said longitudinal adjustment mechanism comprising a first rocker that is mounted in such a way as to be rotatable about a transverse direction extending perpendicular to the direction of travel of the vehicle.

Abstract: An adjustment unit for a vehicle seat is disclosed. Said adjustment unit comprises an inclination adjustment mechanism for the backrest of the vehicle seat. The inclination adjustment mechanism comprises a first rocker which is mounted in such a way as to be rotatable about a transverse direction extending perpendicular to a direction of travel of the vehicle.

Abstract: A foot support (30) for a vehicle seat (1) includes a footrest (32) which is movable from an out-of-use position into a use position. The footrest (32) is guided by a linear guide during the movement from the out-of-use position into the use position. A drive unit (34) is provided for driving the footrest (32). The drive unit (34) includes at least one spindle (40) with at least one spindle nut (42, 44), which is arranged on the spindle (40) and is rotatable relative to the spindle (40). The spindle (40) runs in the transverse direction and includes two threaded regions (46, 48) with threads oriented in opposed directions. A vehicle seat (1) is provided with the foot support (30).
