Windshield wiper construction

Claim 1

A windshield wiper blade construction fabricated in part of a molded polymeric material and comprising, an elongated flexor section adapted to operatively support a wiper element, said flexor member comprising a generally hollow tubular-shaped body of varying wall thickness, with the exterior of said body being of a semi-cylindrical cross-sectional shape for providing an anti-windlift surface and the interior of said body defining an elongated cavity adapted to receive the mounting portion of said wiper element in a manner such that the wiping lip portion thereof projects outwardly away from said anti-windlift surface on said body, a one-piece bridge member having opposed end portions secured to longitudinally spaced portions of said flexor section and an intermediate portion adapted to be operatively secured to an associated wiper arm or the like, the major portions of said bridge member between said intermediate and end portions being of a substantially circular cross-sectional shape for reducing the effect of air passing thereover to lift the assembly away from an associated windshield, said intermediate portion of said bridge member defining a cavity adapted to removably receive the outer end of an associated wiper arm, means extending between the interior of said cavity and said wiper arm outer end for connecting said bridge member to said wiper arm and providing for relative pivotal movement therebetween, and means connecting at least one end of said bridge member to said flexor member, whereby to permit said flexor member and wiper element supported thereon to shift longitudinally of said bridge member to accommodate for windshields of varying configurations.
