Abstract

The invention relates to a wiper lever (10) with a driven wiper arm (12) and a wiper blade (16) linked to it to clean windows, in particular of motor vehicles, which is provided with a band-like, long-stretched-out, elastic supporting element (30) that is curved over its band surfaces, which features a long-stretched-out, rubber elastic wiper strip (24) on its concave curved band surface (31), on whose upper, convex curved band surface (29), in particular in the longitudinal mid-range of the supporting element, a coupling part (32) sits to connect the wiper blade (16) to the wiper arm (12) and wind deflector strip sections (52) extending towards the ends of the supporting element are arranged in particular on both sides of the coupling part and a cap (60) to cover the connecting area between the wiper blade and the wiper arm belongs to the wiper lever, which cap can be locked on the supporting element (30) of the wiper blade and is provided with elastically deflectable locking means (74). Assembly of the cap on the wiper blade in its correct position on the wiper blade is achieved in a simple manner if the supporting element is provided with at least two limit stops (82) each pointing in opposite longitudinal directions of the wiper blade (16) to which corresponding counter limit stops (84) of the cap (60) are assigned.
