Abstract

In a deflector for a windshield wiper including an arm on which a blade is pivoted, the deflector is carried by at least one of the elements comprising the arm and blade of the wiper, in such a way as to divert the air streams. In accordance with the invention, the deflector comprises a main section which is carried by at least one of the said elements of the windshield wiper, together with at least one lateral end portion which is movable with respect to the main section.

Claims

1. A windshield wiper comprising a driving wiper arm, a carrier yoke pivotally connected to said wiper arm to be driven thereby, said carrier yoke comprising an inverted U-shaped channel, a wiping strip joined to a support bar and resiliently suspended within said U-shaped channel, an air deflector mounted on said U-shaped channel, said air deflector comprising a main deflector section coextensive with said carrier yoke, said main section having two ends, a deflector end portion pivotally mounted on each end of said main deflector section, said main deflector section and pivotally mounted end deflector portions having a profiled portion extending to one side thereof in the direction of air movement to cause said air deflector to move in the direction of the windshield upon air movement over said profiled portions;

and means movably linking said end deflector portions with said support bar whereby flexing of said support bar causes pivotal movement of said deflector portions with respect to the main deflector section.

2. An air deflector according to claim 1 wherein said means movably linking said end deflector portions with said support bar comprise at least one finger projecting from each end deflector portion and slidably retained in an opening in the support bar.
