  • Patent number: 4754517
    Abstract: An improved windshield wiper assembly comprising at least one first wiping means, in the form of a rubber wiper blade, a second wiping means in the form of a scrubbing or scouring pad and a deformable bladder therebetween. The bladder can be engorged with windshield washer fluid, which causes the scrubbing pad to deform outwardly, or toward the windshield to be cleaned. As washer fluid leaks from the bladder through perforations and into the scrubbing pad, the windshield wiper is activated in a to-and-fro motion so that the scrubbing pad means scrubs dried insect debris from the windshield.
