Abstract

A wiper blade for a windshield wiper system of motor vehicles is described, in which wiper blade a reinforcing rail is secured against longitudinal movement in its central area on the wiper lip. The securement is performed by a cam pressed from the blade and received in a recess of the reinforcing rail. The relative movement between the reinforcing rail and the rubber wiper strip, which cannot be prevented when bent windshields are being wiped, is thereby evenly distributed over the two ends of the wiper strip. This improves the wiping effect of the wiper blade in comparison to known models, where the reinforcing rail is coupled to one end of the wiper strip.
