Abstract
An adjustment drive of a motor vehicle seat is provided, the adjustment drive, having a control pinion. The control pinion, in the event of a collision, is subjected to a torque which acts from the structure of the motor vehicle seat. Overload protection is provided for an adjustment drive of a motor vehicle seat against forces which act in the event of a collision, using a simple device. This is achieved by the control pinion being rigidly connected to a torsion bar, and the control pinion is situated in an extension of the rotational axis of the control pinion, and free end of the torsion bar being integrated into a drive of the control pinion in a rotationally fixed manner.
