Air deflector for a windshield wiper with a resilient buffer to prevent abrasion
First Claim
1. An air deflector for a windshield wiper assembly operating over the windshield of a vehicle including a wiper arm and a wiper blade carried by said arm, the deflector comprising a profiled portion (7) and attachment means (8) for selectively attaching the deflector to said windshield wiper assembly, the profiled portion is formed with an inner convex surface (11) opposed to an outer concave surface (15), said inner convex surface facing said windshield and being provided with at least one groove, said deflector formed of rigid material and extending substantially parallel with said wiper blade over a major portion thereof to intercept the flow of air across the windshield, said deflector having a free edge (18) and an outer edge (13) spaced from the windshield, and a soft resilient flexible band serving as a buffer between the deflector and windshield looped around said deflector in at least one zone of said deflector parallel to said wiper blade which zone is a small fraction of the overall parallel extent of said deflector, said flexible band being supported in part by said free edge (18) and said outer edge (13) and received in said at least one groove.
