Abstract: A window-regulating assembly selectively moves a window of a vehicle door between an open position and a closed position. The window-regulating assembly includes a rail that is fixedly secured to the vehicle door. The rail extends through a radius of curvature. A lift plate is slidably engaged with the rail. The lift plate is also secured to the window. The lift plate moves the window between the open and closed positions. A lead screw is secured to the rail. The lift plate travels along the lead screw to move the window between the open and closed positions. A drive motor is secured to lift plate. The drive motor receives electrical energy and converts the electrical energy into a selectively bidirectional rotational force to drive the lift plate over the lead screw. A pivot mount extends between the drive motor and the lift plate allowing the drive motor to move through the radius of curvature as the lift plate slides along the rail.

Abstract: A window regulator (10) for operating a window pane of vehicle comprises a base plate (12) having a guide rail (20). A lifter plate (26) is slidably coupled to the guide rail (20) and adapted for supporting the window pane. A motor assembly (32) is secured to the base plate (12) and includes a drive housing and a power motor. A drive shaft, rotatably journaled to the drive housing, has a disc flange supporting a cylindrical shaft and a key shaft spaced from and parallel to the cylindrical shaft. The top and bottom cable drums (34, 36) are supported on the drive shaft, with each of the cable drums including a key slot for aligning with and receiving the key shaft therethrough. The lifter plate is secured to a cable (38) between first and second pulleys (22, 24). At least one compression spring is coupled to one of the cable drums to maintain tension on the cable.
