Abstract
Actuator for vehicle door locks provides powered shifting of a mechanism component while permitting manual operation thereof. A motor powers a driver annulus having internal teeth and notches in respective axial zones with each tooth being diametrically opposite a notch. A spring-loaded index across the annulus interior has a tail co-acting with the notches and a head co-acting with the teeth and is guided by fixed structure that it can only move angularly to displace the component to which it is linked, by indexing past a tooth when its tail is in a notch. Powered movement of the annulus causes the teeth to selectively shift the index, but manual displacement of the component causes the index to spring past the relevant tooth.
