Abstract: A motor vehicle window regulator includes a helically wound wire coil on a flexible lubricating core to form a flexible cable, and the cable is confined within an elongated guide tube having a longitudinally extending slot. The coil is moved longitudinally within the tube by a helical drive gear, and a lower end portion of the cable carries a window lifting bracket or T-bracket having laterally projecting wings. A clamp unit is mounted on each wing and includes a U-shaped clamp body defining a recess which receives a pressure block and a U-shaped gasket for receiving an edge portion of a glass window panel. Set screws thread through the clamp bodies and extend through holes in the wings for engaging the pressure blocks to clamp the edge portion of the window panel to the clamp bodies. Each clamp body comprises a short section of an aluminum extrusion and defines slots or grooves receiving edge portions of the gasket and the T-bracket wing.
