Electrically heated window, process and apparatus for the manufacture thereof

A window (20,50) is provided which includes an array (21,51) of fine, closely spaced wires (22) through which electric current is passed to heat the window. Such windows are useful as vehicle windows, e.g. windscreens, because the heating disperses ice or condensation on the surface of the window, t...

Beschreibung
Zusammenfassung:	A window (20,50) is provided which includes an array (21,51) of fine, closely spaced wires (22) through which electric current is passed to heat the window. Such windows are useful as vehicle windows, e.g. windscreens, because the heating disperses ice or condensation on the surface of the window, thereby improving visibility. According to the invention, at least some of the wires extend along diverging lines, so that the heated area extends over substantially the whole of the transparent portion (49) of the window. It is also described how to achieve a sufficiently uniform heating effect over the extended heated area. A method of manufacturing such windows, and an apparatus (90) for forming such arrays of wires, are also provided.
