TRANSPARENT PANE WITH AN ELECTRICAL HEATING LAYER AND PRODUCTION PROCESS THEREFOR

摘要

The invention relates to a transparent pane with an electrical heating layer, which extends at least over part of the pane face and can be electrically connected to a voltage source by connection means, wherein the connection means comprise a strip-shaped first busbar and a strip-shaped second busbar, which are each electrically conductively connected directly to the heating layer over the entire strip length in such a way that, once a feed voltage has been applied, a heating current flows over a heating field formed by the heating layer, wherein the first busbar is electrically conductively connected directly to at least one first flat ribbon cable and the second busbar is electrically conductively connected directly to at least one second flat ribbon cable, and wherein the pane has at least one pane zone which is free of heating field, in which pane zone at least one electrical zone heating element is arranged, which has such a nonreactive resistance that the pane zone which is free of heating field is heatable by virtue of the application of the feed voltage, wherein the zone heating element is electrically conductively connected directly to the at least one first flat ribbon cable and the at least one second flat ribbon cable in an electrical parallel circuit with respect to the heating field. The invention furthermore extends to a method for producing such a transparent pane, in which the zone heating element is electrically conductively connected directly to at least one first flat ribbon cable and at least one second flat ribbon cable in an electrical parallel circuit with respect to the heating field.
