ABSTRACT OF THE DISCLOSURE A window formed of a glass sheet having a combined electrical heating circuit and bending circuit imprinted there- on. 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 elec- trically 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 heat- ing circuit in a manner isolating the latter from the bending circuit during the formation of sharp bends in the glass sheet.
