Abstract: The window in a door of an automotive vehicle is lifted by an operating lever pivotally mounted on a supporting structure in the door which includes a releasably mounted carrier member of sheet metal. The weight of the window is partly balanced by a spiral spring one of whose ends is attached to the lever. The other end is secured in a gap between two integral lugs of the carrier member which are offset at right angles from the major face of the carrier member.

Abstract: The sliding window in the door of an automotive vehicle is movably guided between a longer and a shorter glass run channel and in a guide groove of a guide member spacedly aligned in the direction of window movement with the channel shortened to accomodate a lock element on the door. Movement of the pane into and out of the groove is facilitated by a flaring orifice of the groove.

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.
