Abstract
A load displacement device for a motor vehicle has a servomotor drivable in two directions of rotation and driving a coupling gear wheel which is guided by a coupling lever. An electromagnet swings the coupling lever against the force of a spring in order to bring the coupling gear wheel into engagement with the teeth of a second gear wheel. The teeth of the coupling gear wheel and/or of the second gear wheel are asymmetrically developed in order to produce a flat engagement angle between teeth of the gear wheels. The flat engagement occurs in both directions of rotation of the second gear wheel and the coupling gear wheel. No tooth displacement forces which cause a swinging of the coupling lever into a disengaged position occur due to the engagement of the teeth.
