Windshield Wiper Blade    

Developed to effectively remove frost, ice, liquid from a vehicle windshield.


Traditional vehicle windshield wipers have a single flexible windshield wiper blade, typically the blade is made of rubber, and housed an elongate frame. They are primarily designed to remove water from a windshield. They may also be capable of brushing away the loose buildup of light snow, but these wiper blades are not sufficiently rigid enough to remove frost and ice accumulating on the windshield.

The patented technology provides a multi-blade ice removing windshield wiper assembly having multiple spaced apart windshield engaging blades. The blades have sufficient rigidity to "bite" into and remove frost and ice collected on a vehicle windshield. The invention has a replaceable flexible windshield wiper blade for removing liquids from the windshield.

A toothed blade "scores" the amassed frost and ice while the windshield wiper arm moves in a first direction. A shaving blade removes the scored frost and ice from the windshield as the windshield wiper arm moves in a second opposite direction. A third flexible liquid removing wiper blade may be optionally engaged to remove liquids from the windshield after the frost and ice have been removed; or in a situation where there is no frost or ice.

Primary Application of the Technology

Automotive - windshield wiper market.
