Abstract
The motor of an electric window or sunroof operating mechanism for a motorcar has a rotor axially movable on a normally fixed base against the restraint of compression springs. A nut on the tubular motor shaft threadedly engages a cable partly received in the shaft. The cable is longitudinally guided on the base and secured against rotation so that it moves longitudinally to open or close the associated window or sunroof when the motor is energized. When the window or sunroof reaches one of its terminal positions, longitudinal movement of the cable is suddenly brought to a halt, and the motor is deenergized. The shock that would be caused by continued inertial motor rotation at arrested cable is absorbed by the compression springs, thereby significantly increasing the useful life of the mechanism.
