A method of manufacturing a wiper blade for a windshield wiper system of a motor vehicle is described, in which wiper blade a pivot pin, that is cylindrical all along its length, is non-rotatably fixed onto a secondary yoke and engages into bearing bushes by way of its ends, which bearing bushes are non-rotatably fixed into the side walls of a primary yoke. This articulated connection is advantageous with respect to corrosional behaviour and thus with respect to the lifetime in comparison to known articulated connections with an articulated rivet that is non-rotatably connected with the primary yoke.

Press fit pivot pin for a wiper blade assembly

A connection and two step method of manufacturing is disclosed for a drive unit for a wiper arm system which consists of a wiper shaft mounted in a bore through a crank arm. The wiper shaft is formed with a groove disposed within the thickness of the crank arm and material from one surface of the crank arm is displaced to form an annular recess which causes crank arm material adjacent the groove to be radially displaced into a groove formed in the wiper shaft to form an axial holding element. The radial distance R1 of the recess from the crank arm bore is substantially equal to the axial distance A1 of the groove below the one crank arm surface to facilitate the extruding process. Knurled areas on the shaft on either side of the groove are press fit into the crank arm bore as a first step in assembling the shaft to the crank arm, bringing a flange into abutment against the other surface of the crank arm.

Drive unit for a wiper system of motor vehicles and method of

A windshield wiper arm including a tension spring which acts upon a holding pin of a swivellable rocker which, upon tilting of the wiper link from its operating position to a tilted position, is abruptly changed from a first end position to a second end position. The swivelling angle of the link between the operating position and a stable tilted position is reduced.

Windshield wiper arm

A windshield wiper yoke and a method for producing same is described. The wiper yoke is formed from a single strip of sheet metal which is bent to have a U-shaped cross-section. The web of the yoke includes a plurality of slots each of which extends in width to or beyond the imaginary bending lines. With slots provided in accordance with the invention, the wiper yoke exhibits relatively good aerodynamic behavior at high vehicle speeds.

Windshield wiper yoke

A windshield wiper arm is described wherein a press fit connection is provided between the wiper rod and a link. The rod carries projections which bite into the softer material of the link.
