Abstract
A wiper blade (10) is proposed that serves to clean windows (30) of motor vehicles. The wiper blade has a bandlike, elongated, spring-elastic support element (12) for an elongated rubber-elastic wiper element (32) that can be pressed against the window and is disposed on the lower band face oriented toward the window and is oriented longitudinally parallel to the support element, and having a coupling part (16) toward the wiper blade, positioned on the upper band face of the support element remote from the window, for pivotably connecting the wiper blade (10) to a counterpart coupling part (18) belonging to a reciprocatingly driven wiper arm (20), in which the pivot axis (40) located in the longitudinal center portion of the support element is disposed substantially transversely to the longitudinal extent of the wiper blade (10), and the coupling part (16) with its flat underside is oriented toward the upper band face of the support element. This particularly effective wiping is achieved even with problematic window curvatures, if support element (12) is curved over its entire length such that the center portion of the support element (12), resting unstressed on the window (30), is…
