Classification: CPC B  H | IPC B  H

Claim 16:
17. A laminated glazing comprising:
a plurality of rigid transparent substrates that are bonded to one another pairwise via an intercalary adhesive layer, at least one of the plurality of rigid transparent substrates being coated with an electrically conductive layer that is substantially uniform in nature and thickness, a zone of said least one rigid transparent substrate having four edges opposing one another in pairs, and
first and second busbars arranged along two opposite edges of said least one rigid transparent substrate,
wherein the electrically conductive layer comprises ablation lines,
wherein the ablation lines of the electrically conductive layer close in on themselves while forming non-conductive strips, each of the non-conductive strips occupying a major portion of a distance between the first and second busbars, a shape of the non-conductive strips being capable of providing a temperature of heating by the electrically conductive layer that is virtually constant over the entire area of the zone, and
wherein none of the one or more ablation lines that form at least one of the non-conductive strips extend to the first or the second busbar such that said at least one of the non-conductive strips is surrounded on all sides by a conductive region of the electrically conductive layer.
