Windshield wiper
First Claim
1. A windshield wiper insert suitably arranged for receipt by a windshield wiper superstructure, said windshield wiper insert comprising:
- a wiper retainer member suitably designed and arranged for retained receipt by said superstructure; and
a unitary, part-cylindrical wiping element assembled to said wiper retainer member, said wiping element having a substantially flat surface and a convex curved surface wherein said curved surface being arranged with a plurality of substantially parallel wiping flaps which are defined by substantially parallel slits, said slits beginning at said curved surface and extending toward said substantially flat surface.

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.

4. A windshield wiper insert suitably arranged for receipt by a windshield wiper superstructure, said windshield wiper insert comprising:
-
a wiper retainer member suitably designed and arranged for retained receipt by said superstructure; and a semi-cylindrical wiping element assembled to said wiper retainer member, said wiping element having a substantially flat surface and a curved surface wherein said curved surface being arranged with a plurality of substantially parallel wiping flaps which are defined by substantially parallel slits, said slits beginning at said curved surface and extending toward said substantially flat surface, and wherein said substantially flat surface is coincident with a diameter of said semi-cylindrical wiping element wherein said substantially parallel slits are arranged substantially normal to said flat surface. - View Dependent Claims (5)
