Abstract
A windshield wiper blade assembly has a blade arm to which a blade subassembly is pivotally coupled. The blade subassembly includes a first blade, a second blade, and a third blade located side-by-side. The first and third blades are formed of a scrubbing material for debris and the second blade is formed of a rubber-like material. Movement in a first direction causes engagement with the windshield to exert a force that pivots the blade subassembly into a first position in which the first and second blades contact the windshield and the third blade is spaced from the windshield. Movement in an opposite second direction causes engagement with the windshield to exert another force which pivots the blade subassembly into a second position in which the second and third blades are in contact with the windshield and the first blade is spaced from the windshield.
