Automobile windshield wiper blade
DCFirst Claim
1. A wiper blade (10) for an automobile windshield (14), with an elongated belt-shaped, flexible resilient support element (12) having a longitudinal axis, on a lower belt surface (22) of which that faces the windshield is located an elastic rubber wiper strip (24) sitting against the windshield that extends parallel to the longitudinal axis, and on an upper belt surface (16) of which a wind deflection strip (42 or 112) is located that has an incident surface (54 or 140) facing a main flow direction of a driving wind (arrow 52), said deflection strip extending in the longitudinal direction of the support element, characterized in that the wind deflection strip has two sides (48, 50 or 136, 138) that diverge from a common base point (46 or 134) as seen in a cross section, and that the incident surface (54 or 140) is located at the exterior of one side (50 or 138), wherein the support element has outer edges, wherein the sides of the wind deflection strip have respective free ends having thereon respective claw-shaped extensions that fittingly grip around the outer edges of the support element at least in sections and engage at least one of the upper belt surface (24) and the lower belt surface (22), so that the wind deflection strip can be snapped onto the outer edges or slid onto the outer edges in a longitudinal direction, wherein the wind deflection strip has a height extending from the base point to ends of the sides farthest from the base point, wherein a substantial majority of the height is above the upper belt surface in a direction facing away from the windshield, and characterized in that the wind deflection strip is designed as a binary component whose longitudinal area provided with the claw-shaped extensions is made of a harder material than a longitudinal area lying closer to the base point.

Abstract
An automobile windshield wiper blade has an elongated belt-shaped, flexible resilient support element, on the lower belt surface which faces the windshield and has an elastic rubber wiper strip extending along the windshield parallel to the longitudinal axis. A wind deflection strip on the upper belt surface has an incident surface facing the direction of driving wind. The deflection strip extends longitudinally, and has two sides that diverge from a common base point as seen in cross section, such that the incident surface is located at one exterior side 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.
