ABSTRACT:
A wiper blade assembly (A) for wiping and cleaning an automobile windshield includes a pair of spaced wiper blade elements (42, 44) having thin resilient wiping edges (42a, 44a). A scrubbing block (50) occupies the entire space between the wiping blade elements and includes a protrusion (52) of the scrubbing block which extends past the wiping edges (42a, 44a) a length, .DELTA.X, to absorb a fraction of the normal force against the windshield and provide a light scrubbing action against the windshield. The mass of the scrubbing block is concentrated between the wiping edges (42a, 44a) to provide rigidity. The scrubbing material accumulates liquid for providing a reservoir which flushes out dirt during to and fro motion of the wiping action.
