Abstract

An automobile windshield wiper blade (10) having an elongated belt-shaped, flexible resilient support element (12), on the lower belt surface (22) which faces the windshield and has an elastic rubber wiper strip (24) extending along the windshield parallel to the longitudinal axis. A wind deflection strip (42 or 112) on the upper belt surface (16) has an incident surface (54 or 140) facing the direction of driving wind (arrow 52). The deflection strip extends longitudinally, and has two sides (48, 50 or 136, 138) that diverge from a common base point (46 or 134) as seen in cross section, such that the incident surface (54 or 140) is located at one exterior side (50 or 138) and the wind deflection strip has a constant cross section along its entire length. The support element has outer edges, and the sides of the wind deflection strip have respective free ends that have respective claw-like extensions that grip the outer edges of the support element, wherein the wind deflection strip can be snapped or slid longitudinally onto the outer edges.
