Abstract

A proposed wiper blade serves to clean the windshields of motor vehicles. The wiper blade (10) has an elongated rubber-elastic wiping strip which can be placed in contact against the windshield to be wiped and which is held substantially parallel to the longitudinal axis at an elongated, springing-elastic carrying element (12). A connection device (16) for complementing connection means of a driven wiper arm (18) which are loaded toward the windshield is arranged at the center portion of the carrying element (12). The connection device has two stop surfaces (36) which are located at a distance from one another, extend transverse to the driving direction, are parallel to one another and oriented in planes extending vertical to the windshield, and cooperate with counter-stops of the wiper arm. A problem-free and economical arrangement of the connection device at the carrying element is carried out in that one of the two structural component parts (12 or 16) which are connected with one another is provided with elastically deflectable catch means which cooperate with the complementing catch means of the other structural component part (16 or 12) in such a way that the two structural c…
