Abstract
A transparent window pane including an electrically heating coating that extends over a large part of the surface of the window pane, or over its field of vision, and which is electrically connected to at least two busbars of low electrical resistance, such that, after an electrical supply voltage has been applied to the busbars, an electrical current flows in a heating field formed by the coating. Further, a heating element includes conducting elements of low electrical resistance, or printed conducting tracks and/or wires, in a zone of the surface not heated by the coating, which preferably lies on the edge of the transparent window pane and on the same face as the coating.
Claims23
A transparent window pane comprising:
- an electrically heating coating that extends over a large part of a surface of the window pane, or over its field of vision, and which is electrically connected to at least two busbars of low electrical resistance, such that, after an electrical supply voltage has been applied to the busbars, an electrical current flows in a heating field formed by the coating, the electrically heating coating extending over an area between the at least two busbars;
- and
- a heating element including conducting elements of low electrical resistance that extend between a first heating element bus bar and a second heating element bus bar, the conducting elements being printed conducting tracks and/or wires, an entirety of the heating element being provided in a zone of the surface that is not heated by the coating and on the same face as the coating, the entire zone being located outside the area between the at least two busbars and positioned between an edge of the electrically heating coating and a lower edge of the window pane, the heating element including the first heating element bus bar and second heating element bus bar are electrically isolated from the at least two busbars and electrically isolated from the coating.
