Abstract
Abstract An attachment for fitting over a standard vehicular windshield wiper which scrapes snow and ice from the windshield. The scraper takes the form of a multiplicity of scraper blocks which are interconnected by chains or hinges so that the scraper blocks articulate over the outer surface of the windshield. Because of the swivel action of the scraper block segments, the curvature of any windshield is followed and effective scraping action is achieved.
