A heated wiper system including at least one frameless, heated wiper assembly is provided. Each wiper assembly includes a flexible squeegee blade and a pair of spaced flexible backing members. The assembly includes at least one and, preferably, a pair of flexible heaters disposed between the blade and their respective backing member to convert electrical energy from a source of electrical energy (i.e., a battery) into heat. Each heater includes a heating element sufficiently dimensioned to travel substantially the entire length of its respective backing member. Wiring connects the battery to the heaters by extending through a sealed center support apparatus which connects the blade, the heaters and elongated resilient spines together between the backing members.

L'invention concerne un système d'essuie-glace chauffé comprenant au moins un ensemble essuie-glace chauffé sans arceau. Chaque ensemble essuie-glace comprend une lame à raclette flexible et une paire d'éléments de renfort flexibles espacés. L'ensemble comprend au moins un dispositif chauffant flexible, de préférence une paire de dispositifs chauffants flexibles, agencés entre la lame et leur élément de renfort respectif, afin de convertir l'énergie électrique provenant d'une source d'énergie électrique (par ex. une batterie) en chaleur. Chaque dispositif chauffant comprend un élément chauffant présentant des dimensions suffisantes pour traverser sensiblement toute la longueur de son élément de renfort respectif. La batterie est reliée aux dispositifs chauffants au moyen d'un câblage qui s'étend dans un appareil de support central hermétique reliant ensemble la lame, les dispositifs chauffants et des supports élastiques allongés entre les éléments de renfort.
