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.
Cette invention concerne une lame d'essuie-glace chauffante s'adaptant aux balais existants ou nouveaux. Elle comprend un élément chauffant par résistance spiralé, en nickel-chrome par exemple, logé dans un évidement faisant sensiblement toute sa longueur. Un conducteur d'alimentation torsadé en cuivre et un fil de mise à la masse insérés dans la lame sont connectés respectivement au premier et au second bouts de l'élément chauffant spiralé servant à empêcher l'accumulation de glace, de verglas ou de neige sur celle-ci. Les bouts de la lame sont alors scellés au moyen d'un produit d'obturation étanche qui sert également à consolider la connexion.
