Abstract
A heated windshield wiper having a heating element for melting ice formations on both the wiper and an associated windshield. The wiper includes an elongated cylindrical body having a hollow interior and three wiping surfaces which project from the body and extend longitudinally along the wiper. A helical heating element is concentrically positioned within the hollow interior of the wiper and is connectable to the vehicle battery to heat the entire outer circumference of the wiper body and the wiping surfaces to melt ice surrounding the wiper and present on the windshield. Alternate embodiments of the present invention include a fluid dispensing arrangement for dispensing fluid over the heating coil and through apertures in the wiping surfaces, as well as an air expansion assembly for expanding the cylindrical body and the wiping surfaces to fracture ice formations surrounding the wiper.
