Spoilerless flat wiper blade assembly
First Claim
1. A wiper blade assembly, comprising:
- a resilient wiper element having a crown with longitudinally extending grooves therein, and a neck extending from said crown to a body having a tip for engaging a window;
an elongate flat metal flexor having a predetermined curvature, said flexor having inwardly facing edges and outwardly facing edges, with said inwardly facing edges being releasably disposed in each of said grooves of said wiper element crown;
an elongate polymeric cover having a substantially flat elongate upper wall extending between opposite ends and a pair of flanges curled inwardly toward one another in spaced relation from said upper wall to provide elongate channels between said flanges and said upper wall, said upper wall having one of an opening or a protrusion between said opposite ends with said outwardly facing edges of said flexor being releasably disposed in said channels; and
a connector adapted for attachment to a wiper arm, said connector having a lower surface for engagement with said upper wall of said cover and a pair of flanges curled toward one another in spaced relation from said lower surface to provide opposite facing pockets slidingly receiving at least a portion of said flanges of said cover therein, said lower surface having the other of said opening or protrusion, said opening and protrusion being configured to engage one another to lock said connector to said cover.

Abstract
A wiper blade assembly has a resilient wiper element with a crown having lengthwise grooves and a tip for wiping a window. An arcuate metal flexor has inner edges disposed in the grooves of the crown and outer edges. An elongate cover has an upper wall and a pair of flanges curled inwardly in spaced relation from the upper wall to provide elongate channels. The outer edges of the flexor are disposed in the channels. The connector is configured for attachment to a wiper arm, and has a lower surface with a pair of flanges curled in spaced relation from the lower surface to provide opposite facing pockets that slidingly receive the cover flanges therein. A projection on one of the connector or the cover is received in an opening of the other of the connector or the cover to lock the connector to the cover.

11. A wiper blade assembly, comprising:
-
a resilient elongate wiper element having a crown with longitudinally extending grooves facing opposite one another and a tip for wipingly engaging a window; a pair of elongate, arcuate metal flexors, said flexors having inwardly facing edges and outwardly facing edges extending along the length of said flexors, said inwardly facing edges being disposed in each of said grooves of said wiper element crown; an elongate polymeric cover having a substantially flat elongate upper wall extending between opposite ends with an opening extending through said upper wall and a pair of flanges curled inwardly toward one another in spaced relation from said upper wall providing channels between said flanges and said upper wall, said channels receiving said outwardly facing edges of said flexors; and a connector adapted for attachment to a wiper arm, said connector having a lower surface for engagement with said upper wall of said cover and a pair of flanges curled inwardly toward one another in spaced relation from said lower surface to provide opposite facing pockets slidingly receiving at least a portion of said flanges of said cover therein, said lower surface having a protrusion depending therefrom and being disposed through said opening to lock said connector to said cover. - View Dependent Claims (12, 13)
