Abstract:
1. A transparent windowpane comprising: at least two busbars; a resistive heating coating that extends over a substantial part of a surface of the windowpane and over a main field of view, the resistive coating being electrically connected, at least indirectly, with the at least two busbars; a heating field including at least one semiresistive region in direct contact with at least one of the at least two busbars, the at least one semiresistive region including wire conducting strands extending away from the at least one of the at least two busbars; and a transverse conducting structure in electrical contact with the semiresistive region, the transverse conducting structure being disposed so as to extend in a direction that is transverse with respect to a direction of extension of the wire conducting strands, wherein an ohmic resistance of the wire conducting strands is less than an ohmic resistance of the heating coating, wherein when a power supply voltage is applied between the at least two busbars, a current flows between the busbars, heating the heating field in the heating coating, and wherein at least one of the wire conducting strands intersects the transverse conducting structure in the semiresistive region.
