Windshield wiper air deflector movable in a single plane to compensate for windshield curvature
First Claim
1. A windshield wiper assembly comprising a driving wiper arm (1'"'"'), an elongated main stirrup (3) driven by said wiper arm, an elongated wiping strip (2) having a longitudinal plane of symmetry (M) which defines two sides of said strip, support means connecting said wiper strip to said main stirrup, an air deflector (47) spaced from and extending substantially coextensively with said wiping strip to one side thereof, portions of said air deflector defining a longitudinal plane (P) which extends at an angle with respect to the plane of symmetry (M) of said wiper strip, means (59) for mounting said air deflector on said main stirrup, said means for mounting comprising plural spaced pivotal connection means between said main stirrup and said air deflector to enable motion between said air deflector relative to said main stirrup in said longitudinal plane (P).

7. A windshield wiper assembly comprising a driving wiper arm, an elongated main stirrup connected to and driven by said wiper arm, said stirrup having front and rear sides, a wiping strip operative over a windshield surface, support means connecting said wiper strip to said main stirrup, an air deflector mounted on said main stirrup and extending substantially coextensively therewith and to one said side thereof, said air deflector comprising a profiled portion convex in shape facing said wiping strip and a planar connecting means, said planar connecting means abutting said main stirrup and secured thereto by pivot means, said pivot means retaining said planar connecting means in abutting relation with said main stirrup while permitting planar sliding motion of said deflector toward and away from said windshield;
- and means coupling said air deflector to said wiping strip to effect said planar sliding motion.
