Claim of US Patent No. 10,694,586

1. A transparent pane comprising:at least one heatable, electrically conductive coating connected to at least two collecting electrodes configured to establish an electrical connection to two terminals of a voltage source, so that an applied supply voltage of the voltage source causes a heating current to flow via a heating field formed between the at least two collecting electrodes, wherein the heating field contains at least one coating-free zone bordered by a zone edge that is formed at least in sections by the electrically conductive coating,
wherein at least one collecting electrode of the at least two collecting electrodes is electrically connected via at least two electrical supply lines to at least one additional electrode,
wherein at least one electrical supply line of the at least two electrical supply lines runs, at least in sections, in the heating field
wherein the at least one additional electrode electrically connects the at least two electrical supply lines to one another, and/or
wherein the at least one additional electrode is subdivided into at least two subregions separated from one another, wherein each of the at least two subregions is electrically connected to at least one of the electrical supply lines, and
wherein in the heating field, at least one coating-free line runs at least in sections along at least one of the electrical supply lines, on a side facing away from the at least one coating-free zone,
wherein the at least one coating-free line runs out from one collecting electrode through the heating field all the way to a level of the additional electrode or all the way to a level of the subregions of the additional electrode, or
the at least one coating-free line runs out from one collecting electrode of the at least two collecting electrodes through the heating field all the way to the level of the additional electrode or to the level of the subregions of the additional electrode and from there out in sections through the heating field section along the additional electrode or longest subregions of the additional electrode, or
the at least one coating-free line begins in the heating field at a certain distance from the collecting electrode,
wherein at least one collecting electrode of the at least two collecting electrodes is subdivided into at least two subregions separated from one another,
wherein each of the at least two subregions of the at least two collecting electrodes is electrically connected via at least one of the electrical supply lines to the at least one additional electrode or to at least one of the subregions of the at least one additional electrode, and
wherein each of the at least two subregions of the at least one collecting electrode is electrically conductively connected to one of at least two flat conductors, wherein the at least two flat conductors are electrically conductively connected to one of the two terminals of the voltage source, or
wherein the at least two subregions of the at least one collecting electrode are electrically conductively connected to a common flat conductor via a common connecting part or via one of two connecting parts, wherein the common flat conductor and the common connecting part or the two connecting parts are arranged electrically isolated from the at least two electrical supply lines.
