ABSTRACT:
A windshield for automotive vehicles is disclosed wherein one or more scraping edges are disposed on its external side in the area wiped by the wiper blades. The scraping edges are an enamel-type material which is formed into strip-shaped profiles and bonded in in raised form to the surface of the glass plate. Varying amounts of metal particles may be added to the enamel material to make it conductive, and, when connected to the vehicle's electrical system, able to thaw ice and snow which accumulates on the lower part of the windshield immobilizing the wiper blade arm. The scraping edges or profiles are positioned at appropriate angles on the windshield to permit water scraped from the windshield wiper blades to run off easily to both sides.
