ABSTRACT:
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.
