Problems solved by technology

Tungsten-filament-type products have the disadvantage of visible wires, which can distract the vehicle driver, especially if some parts of the window (for example, the part of the windshield adjacent to the A-pillar of the car) do not contain Tungsten wire, and therefore some OEMs don't like existing wire-type products

Embodiment Construction

[0062] figure 1 is a schematic plan view of a wire-heated window according to the prior art. The wire heated window 1 is generally trapezoidal in shape and comprises an array of thin, closely spaced wires 2, only a small portion of which is shown for clarity. The wire array 2 is delimited by first 3 and second 4 electrical connection means (or bus bars). The wires in the array 2 extend between the first and second electrical connection means 3 , 4 . These electrical connections 3, 4 connect the array to a power source (not shown) via connectors 5, 6, 7, 8 which may be plug connectors or other connectors. The dotted line 9 indicates the extent of the window's periphery covered by the masking band. The masking band is typically provided by a printed, sintered black ceramic ink positioned on the interior surface of the window. The function of the masking tape is twofold: firstly, it is aesthetically pleasing, as it has the effect of hiding the window edges and covering the a...

Abstract

An electrically heated window comprising at least two layers of glazing material; at least one layer of interlayer material; a grid attached to at least one conductive path of the film; and electrical connection means for supplying electrical current to the grid to heat the window; wherein The at least one layer of interlayer material, grid and film is laminated between the at least two layers of glazing material.

Description

technical field [0001] The present invention relates to electrically heated windows, in particular laminated electrically heated windows comprising a grid attached to at least one conductive path of a film, their method of manufacture and their use. The invention also relates to vehicles incorporating said electrically heated windows. Background technique [0002] Electrically heated windows are commonly used as windshields or rear lights in vehicles to enable defogging or defrosting of the windows during cold and / or wet weather conditions. For windows used as vehicle windshields, the electric heating device is typically provided as an array of thin (with a diameter of less than 30 microns), closely spaced (1 mm-3 mm wire-to-wire distance) wire arrays. Although the wires in the array are generally parallel, each wire is usually arranged in a wave shape, for example, a sinusoidal corrugation, spiral, zigzag, or random pattern, so that when the vehicle driver passes through t...
