Wiper blade coupler with shim
First Claim
1. A shim for a wiper arm for a windshield wiper blade assembly, said shim comprising:
- a base including a deck and an arcuate extension extending from said deck, said base defining a hook shaped upper bearing surface and a hook shaped lower bearing surface;
first and second side walls extending from said base and spaced from one another to define a channel; and
a first pair of opposed tabs extending from said side walls into said channel for coupling said shim to a wiper arm.

Abstract
The present invention is directed to a shim for a wiper arm in a windshield wiper blade assembly. The shim includes a base having a deck and an arcuate extension extending from the deck. The base defines a hook-shaped upper bearing surface and a hook-shaped lower bearing surface. The shim also includes first and second side walls as well as a pair of opposed tabs. The first and second side walls extend from the base and are spaced from one another to define a channel. The opposed tabs extend from the side walls into the channel for coupling the shim to the wiper arm. The present invention is also directed to a wiper arm assembly with a hook-shaped wiper arm and a shim such as that described above.

10. A wiper arm assembly for connecting a wiper blade to a wiper drive motor, said wiper arm assembly comprising:
-
a wiper arm having a hook defining a body segment, a curve, and a tail, said tail being spaced a first distance from the body segment to define an inner diameter of said curve;
a shim having a base and first and second side walls spaced from one another and fixed to the base, said base having a first bearing surface and a second bearing surface parallel to and spaced from said first bearing surface, said base further including an arcuate extension partially defining said first and second bearing surfaces, said first bearing surface being recessed from a top face of the side walls to define a channel between said side walls, said channel having a width defined by the side wall spacing, said shim being attached to the second end of the wiper arm so that said second bearing surface is spaced from the lower body surface, said second bearing surface and said upper tail surface defining a coupling profile that approximates the configuration of a smaller hook arm to permit coupling of the larger hook arm to the wiper blade. - View Dependent Claims (11, 12, 13, 14)
