Abstract
A motor-vehicle window comprises a glass pane having an outer edge and a peripheral black obscuration band extending around the pane edge and leaving a central portion of the pane clear and unobstructed. This band is at least partially formed of a coating-deposited black conductor capable of generating heat when an electric current is passed through it. Thus an electrical current can be passed through the conductor to heat at least a portion of the pane at the obscuration band. The conductor may be positioned side-by-side with the band, disposed in a recess in the band or overlie the band. The conductor may define a heated wiper rest zone on the window.
