Abstract
A wiper blade is suggested for cleaning window panes in motor vehicles. The wiper blade (10) has an elongated rubber-elastic wiping strip (20) which can contact the window pane (18) and is provided at both of its longitudinal sides (30) with open-edged longitudinal receiving grooves which are arranged in a plane approximately parallel to the window pane and in which a strip-like, elongated, resilient carrying rail (12) is accommodated in each instance. The inner edges of the carrying rail (12) which face one another contact a longitudinal web (36) of the wiping strip remaining between the grooves (32) and the two carrying rails (12) are secured in their receiving grooves transverse to their longitudinal extension by a holder which is arranged at the upper strip surface (13) of the carrying rails remote of the window pane. The holder is provided with L-shaped claws (46), the first L-leg (48) traversing the outer edges (52) of the carrying rails and the second L-leg (50) engaging under the respective carrying rail (12). A wiper blade (10) which can be mounted in a particularly advantageous manner is provided when the distance (60) measured transverse to the longitudinal extension of the wiper blade (10) between the inner edges of the first L-leg (48) which face one another is less than the sum of the width (62) of the two carrying rails (12) plus the width (46) of the longitudinal web (36) of the wiping strip (20).
