Laminated glazing comprising a transparent substrate with a heating layer having ablation lines each closing on itself

Abstract

A laminated glazing has a plurality of rigid transparent substrates that are bonded to one another pairwise via an intercalary adhesive layer, at least one of these transparent substrates being coated with an electrically conductive layer that is substantially uniform in nature and thickness, a zone of which has four edges opposing one another in pairs, first and second busbars being arranged along two opposite edges, ablation lines of the electrically conductive layer closing in on themselves while forming non-conductive strips, each occupying a major portion of the distance between the busbars, the 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.
