Abstract:
1. Wiper blade to clean windows, in particular of motor vehicles, with a rubber elastic wiper strip, which can be placed on one band surface of a band-like, elongated, elastic supporting element arranged on the window, whereby the other band surface of the supporting element is covered by a covering part of the wiper blade at least in sections and the covering part grips under holding edges of the supporting element with claw-like projections arranged in the longitudinal direction of the wiper blade, characterized in that the covering part, manufactured of an elastic plastic, is provided with an armoring in the area of its projections whose strength is greater than the strength of the plastic used for the covering part, and characterized in that the holding edges of the supporting element are formed on its two outside longitudinal edges, that two rows of L-shaped holding claws aligned in the longitudinal direction of the supporting element are situated at a distance from one another on the underside of the covering part facing the supporting element, whose one L-leg crosses the plane of the supporting element on its longitudinal edges and whose other L-leg grips under the supporting element in such a way that these holding claws extend from their one L-legs towards one another, whereby the L-legs are provided with the armoring, in that the armoring of the holding claws is embodied to be U-shaped, whereby the U-base reinforces the one L-leg and the U-shape always grips around the longitudinal edge of the supporting element, and in that a plurality of U-shaped metal reinforcements that are a part of the covering part's armoring and are situated at a distance from one another are arranged in the longitudinal direction of the covering part, whose one U-leg is always anchored in the covering part.
