ABSTRACT:
A windshield wiper device, in particular for a motor vehicle, includes a wiper arm (10) that is drivable by a drive, the wiper arm (10) being foldable onto the windshield and able to be folded away from the windshield. The wiper arm is associated with a wiper blade, whereby the wiper arm (10) has a region (11) that faces toward the drive and a region (12) that faces toward the wiper blade. Both regions are connected to two torsion spring elements (13, 14). The torsion spring element (13, 14) are provided with two opposite torsion angles. The torsion spring elements (13, 14) have a square cross section, whose width is greater than its thickness, so that the torsion spring elements (13, 14) are curved in a longitudinal direction toward the windshield or curved away from the windshield.
