Abstract: A cable window lifter with a driving unit includes a drive housing having an internal cavity therein. A cable drum is disposed within the internal cavity and has an internal gear provided along an internal portion of the drum. A pinion gear is disposed within the internal portion of the cable drum and includes teeth that engage the internal gear of the cable drum. The pinion gear is driven manually or by a motor. A support core is disposed between a portion of the internal gear of the cable drum and a portion of the pinion gear teeth.

Abstract: A thin window regulator which can be assembled easily and which requires less installation space inside a door panel is disclosed. Both longitudinal ends of a belt are connected to a pair of sliders and the belt is made into a ring shape. Sliders are movable along a guide rail and are biased closer to each other by springs. Thus, since the ring-shaped belt is wound around a sprocket and the sliding portion, tension is not reduced by a creep phenomenon and the belt does not loosen. One end of the ring shaped belt is formed to be wound around the sliding portion. Thus, the window regulator can be made thinner compared with prior art systems in which both ends of a belt are wound around pulleys and a required installation space inside the door at the upper portion of the guide rail can be made thinner.

Abstract: The invention concerns an electric-motor drive system for a bowden-cable window lifter. The system includes a braking spring in the form of a helical spring in the manner known from manual bowden cable window lifters. This is made possible by the inclusion on the worm wheel of an arcuate slot crossed by a tab affixed to the cable reel and extending to the other side of the worm wheel into the clearance of a ring affixed to the worm wheel. The ring and the tab are enclosed by the helical spring of which the bent-off ends each enter the gap between the tab and ring.

Abstract: A manual window regulator in which a pinion rotatably carried by a window glass and driven by a manual handle is held in engagement with a rack which is fixed to extend in the direction of movement of the window glass, so that a manual rotation of the handle causes the pinion to roll along the rack in meshing engagement therewith so as to drive the window glass thereby opening and closing a window.
