Abstract

In a wiper blade for a vehicular windshield wiper system, the main yoke is equipped with a spoiler constructed such that the overall height of the wiper blade is not enlarged and nevertheless the spoiler is prevented from touching the window pane to be cleaned. The spoiler is formed in such a way that the wiping pattern does not deteriorate at low or higher driving speeds.
