Patent for Sale:Windshield Wiper Blade
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.
