Transparent glazing (1) provided with a resistive heating coating (2) that extends over a substantial portion of one surface of the glazing, especially over the main field of view (A), and is electrically connected, at least indirectly, to at least two busbars (4, 5) in such a way that, upon applying a supply voltage between the two busbars, a current flows between them, heating a heating field in said heating coating (2), said heating field comprising at least one semiresistive zone (6) in direct contact with at least one busbar (4) and including conductive strands (46) produced in the form of thin longitudinal wires, the ohmic resistance of which is lower than that of the heating coating (2), characterized in that at least one conductive strand (46) includes a transverse conductive structure (49) in electrical contact with said semiresistive zone (6).
Vitrage (1) transparent muni d'un revêtement chauffant (2), résistif, qui s'étend sur une partie importante d'une surface du vitrage, notamment sur un champ de vision principal (A) et qui est relié électriquement au moins indirectement avec au mois deux barres conductrices (4, 5) de telle sorte que lors de l'application d'une tension d'alimentation électrique entre les deux barres conductrices, un courant circule entre les barres conductrices en chauffant un champ de chauffage dans ledit revêtement chauffant (2) , ledit champ de chauffage comportant au moins une zone semi-résistive (6) en contact direct avec au moins une barre conductrice (4) et comportant des brins conducteurs (46) réalisés sous la forme de minces fils longitudinaux dont la résistance ohmique est inférieure à celle du revêtement chauffant (2) é, caractérisé en ce que au moins un brin conducteur (46) comporte une structure conductrice transversale (49) en contact électrique avec ladite zone semi- résistive (6) .
