A power door lock actuator includes a one piece molded and centrifugally expandable brake ring that is held on a drive ring to a motor shaft within a lock lift arm driving cup that is freely pivoted to the shaft. A camming member on the drive ring fits within the brake ring so as to retain it to the shaft, to maintain it in a ready position spaced from the cup when stationary, and so as to jam it into the wall of the cup when turning.

Clutch for power door lock actuator

An energy absorbing coupling for use with an electric motor-driven window regulator mechanism, including a torsion spring arrangement between an input gear and an output pinion which provides (1) a driving connection in either direction, and (2) a relative movement or lost-motion connection for absorbing the energy generated by the inertia of the electric motor armature when the window reaches its limit of movement in one direction of the other.
