  • Patent number: 4967437
    Abstract: A heated wiper blade assembly for windshields is provided, in which a plastic blade holder has an upper longitudinal groove for receiving a flat electric heating element enclosed in a ribbon of dielectric. The plastic blade holder also has at its lower portion, a longitudinal slot for receiving a wiper blade therein. A metal cap is positioned over the heating element and crimped around the plastic holder to form a wiper blade subassembly. Such subassembly is then mounted in an enclosing wiper housing such that the upper portion of the blade holder with heating element and metal cap or radiator, are positioned within the housing cavity and the lower portion of the blade holder and the wiper blade, face away from the housing, so that upon application of electricity to the heating element, heat is directed into the housing and also applied to the holder and indirectly to the wiper blade.
