Laminated glazing comprising a transparent substrate with a heating layer having flow lines which altogether are of variable width

A laminated glazing comprising several rigid transparent substrates adhesively bonded to one another in pairs via an interlayer adhesive layer, at least one transparent substrate of the several rigid transparent substrates being coated with an electrically conductive layer, a zone of the transparent substrate exhibiting four opposite edges in pairs, a first and a second busbar being positioned along two opposite edges, the electrically conductive layer exhibiting a set of flow lines for guiding an electric current between the first and second busbars, wherein the set of the flow lines for guiding the electric current between the first and second busbars consists of ablation lines formed within a thickness of the electrically conductive layer that is coated on the at least one transparent substrate, said ablation lines being of variable width, and wherein at least one of the ablation lines has a width that varies along a length of said at least one of the ablation lines.
