Abstract
The invention relates to miniature drives for use in automobile locks. A return of the mechanism once the lock is opened and the motor is shut down is prevented completely mechanically. For this purpose, the worm wheel is associated with a mechanically active locking element which allows first to slightly turn back the wheel to unlock and reduce the load on the mechanism, but then prevents any further rotation against the direction of drive.
Claims10
Microdrive for the activation of motor vehicle latches with a gear assigned to the latch housing with a worm drive wheel and a motor which has a lock which prevents the gear from rolling back, characterized in that the lock is a mechanically effective locking part and the gear with a wormgear wheel is a locking part enabling slight rolling back which is then designed to prevent further rotation opposite to the drive direction.
