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: A cross-arm window regulator for moving a window between raised, intermediate and lowered positions in a vehicle door, includes a resilient stop cushion housed in the lift channel mounted on the glass. Sliders mounted on the ends of the lift and cross arms engage the ends of the cushion as the window nears raised position, gradually compressing it to cushion window movement to raised position. If the geometry is the same for raised and lowered positions, the same cushioning will also occur in the window lowered position. The spring rate increases as compression occurs. The cushion can be a foam butyl rubber strip or a metal spring of various types. The spring rate can be tailored by making the cushion a dual density foam strip, a foam strip with holes of varying sizes to provide a variable cross-section, or a coated foam strip. An integral stop can be included in the form of a hard plastic shell for the foam strip or spring.

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.
