Patent ID: 8022334

Claim:
A heatable glass pane having a base edge and a side edge, said heatable glass pane consisting essentially of two contact bus bars for connection to voltage source poles of different polarity, and a set of heating wires which are in electrical contact and in physical contact with said two contact bus bars, wherein said heating wires have essentially the same lengths, wherein said heating wires are laid without any points of overlap in relation to one another, wherein said heating wires comprise an outermost heating wire which makes contacts with said contact bus bars at their outer ends, facing away from one another, wherein said heating wires further comprise a plurality of inner heating wires, wherein said inner heating wires are laid out so that they have at least one compensation loop, the compensation loop creates essentially same length of the heating wire, and wherein said bus bars are located parallel to and adjacent to said base edge of the heatable glass pane and said bus bars are arranged essentially in a line in their axial directions, spaced apart a short distance from one another.
