ABSTRACT:
A motor-vehicle seat displaceable relative to a fixed support in a motor vehicle between a pair of end positions is powered by a motor whose output shaft may be rotatable in only a single predetermined rotational sense. Mechanism is provided having an input rotatable in one direction for displacing the seat on the support of the motor-vehicle from one end position into the other end position and rotatable in the other opposite direction for displacing the seat on the support from the other end position into the one end position. A motion-converting transmission is connected between the output shaft of the motor and the input of the displacement mechanism for automatically driving this input alternately in the one direction and in the other direction on continuous rotation of the motor output shaft in only the one sense. This motion-converting transmission may comprise a crank so that the motor-vehicle seat is automatically displaced from the one end position into the other and then back into the one position without the actuating motor having to stop.
