Abstract
The invention provides a retainer clip for holding the backing member of a windshield wiper assembly against longitudinal movement in the claws of a superstructure in which it is mounted. In a first embodiment a claw-like body has a resilient tongue formed on its upper wall by two parallel slots, the tongue having on its underface a projection that cooperates with a recess in the backing member to retain them against relative movement. A longitudinally-extending transverse flexible integral arm has a hook portion at its end that can embrace a superstructure mounting claw, so that the claw is trapped between the clip body and the hook portion against longitudinal movement, and the backing member is thereby retained in the superstructure. A preferred backing member is provided with a number of the above-mentioned cooperating recesses spaced longitudinally from one another, each of which is designated to make the combination suitable for a replacement wiper blade assembly of a different size and/or a different manufacturer. In an alternative clip structure two opposed hook portions are provided for claw embracement by a thin metal U-shaped member that is interposed between the clip bo…
