Abstract: A replacement assembly for a wiper blade for cleaning the windshield of a motor vehicle includes an elastic wiper blade assembly that has a top part and a wiper lip, with one respective elastic rail inserted into two lateral longitudinal grooves in the top part and retained therein by a retaining clip. An end piece on the end and the retaining clip both hold the elastic rails in the longitudinal grooves. The end piece is attached to one end of the wiper blade assembly, with said end piece securing the wiper blade assembly on the wiper blade frame in the longitudinal direction with the end to insure simple and safe handling of the replacement assembly.

Abstract: The invention relates to a four-joint wiper arm for a windshield wiper system of a motor vehicle, with the so-called four-joint consisting of a primary lever that can be connected to the primary shaft, a control lever arranged lateral to the former, that can be connected to a supporting arbor and a coupling link connected by means of one joint respectively to the free ends of primary lever and control lever. At the end at which the control lever is coupled, the joint section of the wiper arm is pivoted to the coupling link in a conventional way. In order to preclude distortion in the four-joint assembly and thereby improve the wiping quality, one of the two joints is in the form of a ball-and-socket joint between the coupling link and primary lever or control lever and the other is in the form of a universal joint.

Abstract: A wiper which may be enhanced with a wind guide device in which the wiper has a support bracket system to accommodate and guide a wiper strip. Two subordinated brackets are positioned in a swivel bearing via a joint pin or joint bolt, resp., such that they may be rotated. The ends of the joint pin or the joint bolt, resp., project from the outside of the side walls of the primary bracket and form stop bars. The wind guide device is equipped with two mounting brackets which overreach the primary bracket in the range of the swivel bearing and may be attached reversibly on the stop bars while correspondingly designed recesses in the side walls of the mounting brackets accommodate the stop bars.
