Motor vehicle window or sliding roof drive - has coupling half linked to axially movable drive shaft displaceable against elastic element to engage coupling

摘要

The device provides a drive for the windows or sliding roof of a motor vehicle. It includes a worm-type transmission coupled to a pinion-type structural element acting on the movable element. The halves of the coupling work together in form-locking connection. One half is firmly connected to the axially displaceable drive shaft, and this displacement causes the coupling to be activated. The shaft may be displaceable from one operative position against the force of an elastic element (46), and releasable against its return force.
