ABSTRACT:
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.
