ABSTRACT:
A T-shaped scraper for curved windshield and windows of a newer aerodynamically designed automobile comprises an elongated handle at the stem and a blade with an arc-shaped scraping edge which provides various scraping curvatures by varying the angle of attack. For more intimate contact between a wider portion of the scraping edge and the glass surface, a combination of the scraping induced normal force on the edge, elastic deformations of the edge and the custom profiled blade are used.
