Abstract

A drive bearing for a windscreen wiper system wherein two actuator rods for actuating two wiper arms are driven by a motor crank. The two bearings are concentrically nested one within the other thereby allowing the driving forces of the two rods to extend in one plane. Other features include the association of the individual bearing elements to the actuator elements, and the design of the bearing faces.
