Abstract

A heated windshield wiper blade unit suitable for incorporating into existing or new windshield wiper assembly. The blade comprises a spiral coiled heating element of resistance wire, such as Nichrome, disposed in the blade substantially along its entire length within a passageway. A stranded copper live wire and a ground wire enter the blade to establish electrical contact with the respective first and second ends of spiral coiled heating element which serves to conduct heat to entire wiper blade assembly so as to prevent accumulation of ice, sleet or snow on the wiper blade. The ends are then sealed with a moisture proof sealant which also serves to maintain end connectors and wires intact.
