ABSTRACT:
A displacement device for use with windows and sliding roof for motor vehicles includes a toothed rack disposed within the vehicle in a direction parallel to the displacement direction. A motor-gear housing is positioned adjacent the toothed rack and includes an electrical driver, a central shaft positioned perpendicular to the rack, and a pinion gear on the shaft that is engaged with the toothed portion of the rack. The rack and housing include guide surfaces that are positioned to correspond with one another. A guidance element is attached to the housing and the rack is interposed between the guide surfaces of the housing and the guidance element to control and guide the movement of the housing vis-a-vis the rack during activation of the electrical drive. Attachments extend from the housing and are configured to accommodate placement of an edge portion of a window therein. A flexible ribbon-like electrical power cable extends from the housing in a direction parallel with the window and rack and is configured in a loop to minimize the space required within the vehicle for displacement operation of the housing and window.
