Actuator

A vehicle seat having an actuating device, comprising:

• a drive part coupled to a rotatable seat back of the vehicle seat, the drive part having an axis of rotation aligned with the axis of rotation of the seat back;
• an output part having an axis of rotation aligned parallel with and located distal from the axis of rotation of the drive part, the output part being movable by the drive part from an initial position and toward a final position, wherein one of the output part and the drive part has a first region and a second region, and the other of drive part and the output part interacts with the first and second regions, the position of the output part changing upon interaction of the drive part with the first region and the position of the output part not changing upon interaction of the drive part with the second region of the output part and wherein the drive part prevents the output part from moving back toward the initial position when the drive part is interacting with the second region.
