A window formed of a glass sheet having a combined electrical heating circuit and bending circuit imprinted thereon. The heating circuit comprises a series of longitudinally extending conducting lines interconnecting spaced bus bars. The bending circuit includes resistance elements in the form of electrically conducting paths extending transversely of the sheet along the lines about which the sheet is to be sharply bent and which intersect the longitudinal conducting lines of the heating circuit. Interruptions are formed along the bus bars of the heating circuit in a manner isolating the latter from the bending circuit during the formation of sharp bends in the glass sheet.

An electrically heated window system having at least two independently heatable zones wherein each zone includes its own independent resistance heating element which provides a path for the flow of electric current. A selected region in one of the zones includes a secondary heating component which produces a relatively high temperature in this region of the zone which controls a thermostat in thermal contact therewith. The thermostat initially connects an electrical potential to the one zone and then automatically cycles the electrical potential between the two zones in accordance with the rise and fall of the temperature in said selected region.
