Abstract
In a windshield wiper, which includes a wiper arm carrying a wiper blade and driven by a wiper shaft to oscillate against a windshield pane being wiped, a lever mechanism is provided, which imparts to the wiper arm additionally a straight-line shifting movement in the direction of elongation of the wiper arm. The lever mechanism includes two four-joint guides, each of which includes two rocking levers positioned at two sides relative to the axis of the wiper arm, and a coupling rod which is connected by joints to each of the rocking levers and to the wiper arm.
