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.
