ABSTRACT:
A windshield wiper assembly providing improved wiping characteristics. The wiper assembly includes a wiper arm, a superstructure, and a flexible wiper insert received within the superstructure. The wiper insert includes a flexible elongate beam received within the superstructure at both ends and which serves to uniformly distribute the force transmitted by the superstructure from the wiper arm along the length of a flexible wiper strip which forms a part for the wiper insert. In its unflexed configuration, the elongate beam is characterized by a first surface which is elliptically curved convexly along the length of the beam and a second oppositely disposed surface which is flat. When the elliptically curved surface is flexed due to the application of a force from the superstructure at each end of the beam the force is equally distributed along the length of the beam.
