Rear window wiper mechanism for a motor vehicle

A vehicle body having an opening rear window hinged along one edge for opening movement, a window wiper drive unit mounted on the inner side of the window adjacent said one edge part-way along the edge, the drive unit having an output shaft extending through an opening in the window with the shaft axis normal to the plane of the window, a wiper secured to the shaft on the outer side of the window, a motor unit for the wiper drive unit mounted on the inner side of the vehicle body, a drive transmission comprising a rigid tube extending from the motor unit to the drive unit through which a flexible transmission element extends and means to guide the transmission along the inner side of the window generally parallel to said edge to the wiper unit so that the transmission can accommodate opening and closing of the window, the rigid tube being rotatably connected to the wiper drive unit to permit the drive unit to turn with respect to the tube as the window is opened and closed.
