Abstract

A wiper blade is proposed, which is used to clean windows, in particular of motor vehicles. The wiper blade is arranged with a rubber elastic wiper strip (24) on the one band surface (22) of a band-like, long-stretched-out, elastic supporting element (12) and can be placed on the to-be-wiped window (14). The other band surface (16) of the supporting element is covered by another component (40) of the wiper blade (10), at least in sections, and this covering part is provided with claw-like projections (54) arranged in the longitudinal direction of the wiper blade, which grip under holding edges (38) of the supporting element. A particularly tension-neutral and easily mountable wiper blade is achieved if the covering part (40), manufactured of an elastic plastic, is provided with an armoring (60) in the area of its projections (54) whose strength is greater than the strength of the plastic used for the covering part.
