Title (EN) DE-ICING DEVICE FOR WINDSHIELD WIPERS
(FR) DEGIVREUR POUR ESSUIE-GLACES
Abstract: front page image
(EN)A device for de-icing windshield wipers and the like, and takes the form of an electric heating element (10) shaped as an elongate strip with substantially the same outside dimensions, and also to advantage with the same resiliency characteristics, as one of the spring strips normally inserted in longitudinal grooves on either side of a wiper blade to give it the necessary lateral stiffness and vertical springiness. This strip-like electrical heating element is intended for inserting in one of said grooves in the blade instead of the normal spring strip. The heating element is built up from an outer metal casing (13) having said strip shape and resiliency characteristics, and being provided with an internal axial duct in which an insulated (12) electric resistance wire (11) is disposed. At its one end, this resistance wire is connected to an electric supply lead at one end of the casing, while at its other end the wire is electrically connected to the casing in the vicinity of the other end of the latter, so that the casing can function as ground or return lead for the heating element. The outer metal casing can to advantage consist of a metal tube flattened to the rectangular shape of a normal strip.
(FR)Degivreur pour essuie-glaces et analogues constitue d"un element chauffant electrique (10) sous forme d"une bande ayant essentiellement les memes dimensions exterieures et avantageusement la meme elasticite qu"un des ressorts a lame qui sont usuellement disposes dans des rainures longitudinales de chaque cote d"une lame d"essuie-glace pour lui conferer la rigidite laterale souhaitee et l"elasticite verticale voulue. Cet element chauffant electrique sous forme de bande est prevu pour etre introduit dans l"une desdites rainures a la place d"un ressort a lame metallique exterieur (13) ayant ladite forme de bande et ladite elasticite et comportant interieurement un conduit axial dans lequel est loge un fil de resistance electrique (11) pourvu d"une isolation (12). Une extremite de ce fil de resistance est reliee a une source d"electricite tandis que l"autre extremite est connectee electriquement au manchon pres de son extremite de telle facon que le manchon puisse agir comme terre ou conduite de retour. Le manchon metallique est forme avantageusement a partir d"un tube metallique qui a ete aplati pour obtenir la forme rectangulaire d"une bande normale.
