  • Window lift mechanism
    Patent number: 10385603
    Abstract: A window positioning apparatus for a vehicle comprising a window panel, a frame in which the window panel is guided between a closed position closing a window opening in the frame and an open position opening the window opening, and a multi-stage telescoping screw actuator mechanism connected between the window panel and the frame, the actuator mechanism being extendible to move the window panel from its open position to its closed position and collapsible to move the window panel from its closed position to its open position. The multi-stage telescoping screw actuator mechanism includes a plurality of screw members of progressively decreasing diameter respectively telescopically disposed within a next adjacent screw member of larger diameter.
