In a window lifting mechanism 10 for motor vehicles, with an engagement member 16 which engages at a window pane, a slide member 24 which is connected with the engagement member and is supported to be slidable at a guide rail 26, and a cable drive 12 to move the engagement member 16 along the guide rail 26, the engagement member 16 is supported at the slide member 24 so as to be slidable in the longitudinal direction X of the guide rail 26, i.e. simply by attaching the engagement member 16 at a bearing part which in turn is supported to be slidable at the slide member 24 in the longitudinal direction X. With this simple arrangement an increase in the lift of the window lifting mechanism at a specified length c of the guide rail 26 is achieved, while maintaining the mechanical stability of the window lifting mechanism with respect to tilting motions of the window pane which lie in the plane of the window pane. Preferably a steel band loop 44 is used as the bearing part. In an additional embodiment, the steel band is slidably supported directly at the guide rail which is constructed as a C-rail, wherein at least one end of the guide rail a deflection for the band is provided.

Window lifting mechanism, particularly for motor vehicles

A window driving assembly particularly for a motor vehicle having an elongated guide rail upon which a driven member having a windowpane supported thereon is mounted for sliding guided movement between two terminal positions. A cable extends from a cable drive mechanism over a pair of deflection pulleys located at opposite ends of the guided path of the driven member into engagement with opposite ends of the driven member. In order to extend the length of the path of movement of the driven member or to shorten the distance between the deflection pulleys, the cable is connected at runoff points at opposite ends of the drive member which, when the drive member is at a midway point in its path of travel, are farthest away from the deflection pulley to which they are connected.
