Abstract
A universal window-actuator drive unit capable of use with either a cable pulley window-actuator or an arm-scissors type window-actuator. A worm shaft extends from a driving motor and is rotatably coupled to a worm gear. The worm gear is coupled in a rotational-slave relationship to a driving disk, and both the worm gear and the driving disk are rotatably supported on a gear housing shaft. At its end opposite the driving disk, the gear housing shaft includes an actuator shaft collar concentrically surrounding the gear housing shaft and having a grooved toothing about its inner circumference. This inner grooved toothing enables the window-actuator drive unit to be coupled to either a drive pinion of an arm-scissor type window actuator or a cable pulley of a cable pulley window actuator, each of which include couplings having an outer grooved toothing corresponding to the inner grooved toothing of the actuator shaft collar.
