Heatable Glass Pane

Abstract

Disclosed is a heated window pane (1), particularly for side windows of vehicles, comprising two differently polarized contact busbars (6, 7) which extend essentially parallel to each other in the longitudinal direction thereof as well as parallel to a bottom edge (2) of the heated window pane (1), and a bunch of heating filaments (9) that electrically contact the contact busbars (6, 7). The inventive window pane (1) is characterized in that the contact busbars (6, 7) are arranged substantially along one line in the longitudinal direction thereof while the heating filaments (9) have essentially the same length such that uniform heating of the entire window pane (1) can be ensured. The heating filaments (9) can be made to have the same length by configuring compensation loops (11) and/or varying the amplitude of a heating filament (9) that is disposed in a wavy shape.
