Abstract

A window-actuator drive unit includes a driving disk, which is rotatably supported on an axle of the gear housing. The driving disk is placed in a rotational-slave relationship with the worm gear of a reduction gearing which is connected on the load side to an electric drive motor. The driving disk is connected to the worm gear by way of a damping separator and on its unattached end is a shaft collar which has outer teeth used for an interlocking, rotational-slave relationship either with a cable pulley of a cable window actuator or the driving pinion of an arm or scissors-type window-actuator. The inner teeth of both the cable pulley and the driving pinion correspond to the outer teeth of the shaft collar.
