Abstract

An electrically heated rear screen including a window formed of laminated glass layers separated by a thermoplastic interlayer and having electrical connection elements provided at opposed lateral edges of the window. Plural parallel connected horizontally extending resistive heating wires are embedded in the thermoplastic interlayer. The resistive heating wires are formed as meandering loops having an odd number of loop segments extending across the width of the window. At the opposed lateral edges of the window, the resistive heating wires have opposed end segments which follow a path along the corresponding lateral edges of the rear screen a short distance apart to a respective common electrical connection element.
