Removable heated cover for a windshield wiper blade assembly

Abstract

An electrically heated cover for wiper blade assemblies includes a cover body having front, rear, right-hand and left-hand end walls and a top wall having a longitudinal access opening for allowing ready connection of the wiper blade assembly to a wiper arm. Electrical resistance heating elements are attached to the inner surface of the cover body and are electrically connected to the vehicle electrical system to provide heat that prevents formation of ice on the wiper blade assembly, the wiper blades and the windshield during severely cold snowy weather. The cover is held in place by a plurality of thumb or set screws through the cover that bear against the wiper blade assembly and are kept from slipping by rubber bushings that contact the wiper blade assembly. The cover can be easily removed and installed and allows completely normal operation of the windshield wipers, and requires no alteration of pre-existing equipment.
