Transparent pane with an electrical heating layer, method for its production and its use

Transparent moon (1) with at least one heated electrical conductor coating (8) that is connected with at least two collecting electrodes (11, 11 ') provided for the electrical connection with the two poles of a voltage source such that, by applying a supply voltage, a heating current flows through a heating area (12) formed between the at least two collecting electrodes, wherein - the heating area (12) has at least one communication window (14) without a heated electrical conductor (8), - the heated electrical conductor jacket (8) is delimited by a circumferential covering edge (10) and an electrically conductive unlined circumferential fringe (9), extending to the circumferential moon edge (5), presenting the transparent window (1) - at least one coating (8 'or 8' '') that can be heated electrically outside the heating area (12) and spatially separated from it by a collecting electrode (11 or 11 '), along length of a first side (6 or 6 ') of the moon edge (5), - being provided in the area of ​​the two second sides (7, 7') of the moon edge (5) in each case at least one electrode additional (18, 18 '), - which is connected to a collector electrode (11 or 11 ') in each case through at least one current supply line (15, 15'), - which extends along the assigned coating edge (10) in each case and along the two second sides (7, 7 ') of the moon edge (5) at least in some sections - in the assigned marginal strip (9), - on the assigned section of the edge (10) of circumferential lining electrically decoupled from the heating area (12) in each case through at least one line (16 or 16 ') without assigned lining and / or - on and / or on the assigned electrical conductor liner (8 '') in each case outside the heating area (12) electrically decoupled from the heating area (12) in each case through at least one line (16 or 16 ') without assigned lining, and - in the electrical conductor (8 'or 8' '') - includes at least one connecting conductor (19) electrically assigned to the at least one additional additional electrode (18, 18 ') and electrically connected to the electrode collector (11 or 11 ') of opposite polarity through the electrically conductive coating (8' or 8 '' '), characterized in that the transparent window includes in the covering (8 or 8`` ') an electrical conductor - at least two systems (16' ') located opposite each other symmetrically with respect to the vertical center line and axis of symmetry (M ) of the transparent moon (1), formed in each case by at least four unlined lines that are arranged in such a way that, when a supply voltage is applied, they direct the heating current flowing from the at least two additional electrodes (18, 18 ') to the at least one collector electrode (11 or 11') of the opposite polarity in each case through at least two current paths ( a1, a2 to an) in each case through the at least two connection conductors (19) assigned to them in each case, - being applicable for current routes (a1, a2 to an) in a system (16 '') equation I: VH1 = h1: bn = 0.5 to 2.0 (I), where n represents an integer from 2 to 30, (a1) designates the current path from the additional electrode (18) to the section of the connecting conductor ( 19) closest opposite, (h1) represents the height of the current path a1, (a2 ... an) designates the other current paths, bn represents the width of another current path an and (VH1) represents the relationship mathematics (h1: bn).
