Embodiment Construction

[0056] figure 1 is a schematic plan view of a wire heated window with wire-free regions. The wire heating window 1 is generally trapezoidal in shape and comprises an array 2 of thin, closely spaced tungsten wires. For clarity, only a small portion of the metal lines of array 2 are shown. Not all metal lines in array 2 are shown, and variations in the pitch of the metal lines are not shown. The array 2 of metal lines is delimited by a first electrical connection means or first upper busbar 3 and a second electrical connection means or second lower busbar 4 . The upper and lower refer to the figure 1 (and image 3 ), the orientation of the window when the window is installed in the vehicle. Metal lines within the array 2 extend between the upper busbar 3 and the lower busbar 4 .

[0057] The bus bars 3, 4 electrically connect the array to a power source (not shown) through electrical connectors 5, 6, 7, 8, which may be plug connectors or other suitable connectors.

Abstract

An electrically heatable window comprising two layers of glazing material, a layer of interlayer material between the layers of glazing material, a first bus bar and a second bus bar, and between the first bus bar and the second bus bar An array of spaced metal lines extending between them. The window includes a metal line-free region aligned with a first portion, and the array of spaced apart metal lines includes a first portion and a second portion. In order to reduce the non-uniformity of heating, the pitch of the metal lines of the first part is larger than the pitch of the metal lines of the second part. A method for forming the electrically heatable window and a vehicle including the electrically heatable window are also disclosed.

Description

technical field [0001] The present invention relates to a laminated window with metal wires, more particularly, the present invention relates to an electrically heatable laminated window with metal wires, and a method for manufacturing a laminated window with metal wires , In particular a method of electrically heatable laminated wire-lined windows. Background technique [0002] Windows are known which comprise two or more sheets of glazing material, especially glass, which are passed through an interlayer material, usually made of polyvinyl butyral (PVB ) made) laminated together. Such windows may be mounted as windshields, rear windows or other windows of automobiles or other vehicles, or as windows (especially windshields) of commercial vehicles, motor vehicles or aircraft, or may be mounted on boats or ships. [0003] Laminated windows, especially for vehicles, may have electrically heatable regions. The electrically heatable region can be used to reduce condensation ...
