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.
