Abstract
A shock absorbing ice scraper for scraping ice, snow and frost from windows of a vehicle includes a head portion and a shaft portion, where head portion has a scraper blade. The handgrip has a bore, where the insert is press-fitted within the bore of the handgrip and a pair of opposite protruding tabs extending outward for preventing transverse movement of the shaft portion of the scraper within the bore of the handgrip. The coil spring is located between the head portion and the handgrip for absorbing the impact force of the reciprocation movement of the head portion of the scraper. The O-ring is located between the head portion and the coil spring to further absorbs the impact force of the head portion of the scraper.
