Title
(EN) HEATED WINDSHIELD
(FR) PARE-BRISE CHAUFFANT
Abstract
(EN) The invention relates to a heated laminated windshield formed by two sheets of glass joined by an intermediate thermoplastic sheet. The windshield comprises: a conductive layer system which covers the majority of the surface of one glass sheet of the windshield and which is powered by busbars; and a network of heating wires, which is in contact with the layer system and not insulated electrically therefrom, said network being located in the wiper rest area. The two heating means, the layer system and the wire network are all located on the same side of the intermediate thermoplastic sheet. In addition, lines are provided in the area corresponding to the wiper rest area in order locally to break the electrical continuity of the conductive layer system, said lines and the heating wire network being disposed such that the current being supplied to the heating wires flows along the entire length of the wires, electrically insulating the heating wires from the busbars and the wire loops from one another.
(FR) L'invention concerne un pare-brise feuilleté chauffant constitué de deux feuilles de verre réunies par une feuille intercalaire thermoplastique, comprenant d'une part un système de couches conducteur couvrant l'essentiel de la surface d'une feuille de verre du pare-brise alimenté électriquement par des busbars, et d'autre part un réseau de fils chauffants en contact avec le système de couches, électriquement non isolé de celui-ci, réseau situé dans la zone de repos des essuie- glace, les deux moyens de chauffage, système de couches et réseau de fils,étant situés du même côté de la feuille intercalaire, des lignes rompant la continuité électrique localement du système de couches conducteur étant pratiquées à l'emplacement correspondant à la zone de repos des essuie-glaces, ces lignes et le réseau de fils chauffant étant disposés respectivement de telle sorte que le courant alimentant les fils chauffant passe sur toute la longueur de ceux-ci, en isolant électriquement les fils chauffants des busbars, et des boucles des fils entre elles.
