Abstract
A control device for an electric motor which drives a motor vehicle part which is displaceable between reference positions, which is provided with a switch unit ( ) for controlling the motor, there being a ratchet wheel ( ) which, when the motor vehicle part is displaced, is forced to rotate less than 360 degrees between its end positions via an eccentric gearing ( ) and actuates the switch unit depending on the rotational position of the ratchet wheel, the eccentric gearing having an externally toothed internal wheel and an internally toothed external wheel ( ) which is interdigitally engaged to it, the ratchet wheel being supported for wobble motion with reference to a motor-driven shaft ( ) which coupled to move with the motion of the displaceable motor vehicle part and which is pivotally mounted in a gearing housing ( ), the ratchet wheel forming either the internal wheel or the external wheel of the eccentric gearing, the ratchet wheel and the switch unit being located within the gearing housing. The ratchet wheel ( ) and the switch unit ( ) are made for contactless actuation of the switch unit.
