An electrically conductive contact wire, which is different from the at least one heating wire, is arranged between the substrate and the intermediate layer or between the cover pane and the intermediate layer. At least one region of the electrically conductive contact wire forms a capacitive switching region. The capacitive switching region has at least one contact region and one connection region.

A glass laminate article having high efficiency heat transfer characteristics and related systems and methods are provided. The glass laminate article has a thin, high heat conductive inner glass layer that efficiently transfers heat from a heating system throughout the glass article. The glass laminate article may be used as a vehicle window and used as part of a heating system and method for defogging or defrosting the vehicle window. The glass laminate article may include a heating coating adjacent an outer glass layer which further improves heating efficiency.

A window glass for a vehicle includes a glass plate for window of the vehicle, a defogger on the glass plate, and an antenna on the glass plate. The defogger includes a pair of bus bars extending in a height direction of the glass plate, a first defogging area formed by a plurality of first heating wires connected between the pair of bus bars and extending in a widthwise direction of the glass plate, and a second defogging area formed by at least a second heating wire connected to the pair of bus bars or to the first defogging area and extending in a protruding manner to one side in the height direction to surround a wiring-prohibited area. The antenna is provided in at least one of areas that are an area on left of the second defogging area and an area on right of the second defogging area.

The present disclosure relates to a method of manufacturing a curved laminated glass and the curved laminated glass. The method comprises preparing a curved soda lime glass, providing a functional layer on one surface of an alkali-free glass, disposing a lamination film or a bonding agent between the curved soda lime glass and the functional layer, and elastically deforming the alkali-free glass, and laminating the alkali-free glass with the curved soda lime glass.

A polyvinyl acetal resin film for laminated glass, a viscosity of toluene/ethanol=1/1 (by mass ratio) solution of a polyvinyl acetal resin in a resin composition constituting the polyvinyl acetal resin film with a concentration of 10% by mass, measured at 30 rpm and 20 C. by using a Brookfield-type (B-type) viscometer, being more than 200 mPa.Math.s, the polyvinyl acetal resin film comprising a plasticizer in an amount of 0 to 20% by mass based on a total mass of the resin composition constituting the polyvinyl acetal resin film, and the polyvinyl acetal resin film having a thickness of 10 to 350 m.

A laminated glazing of a vehicle includes a first extra clear glass sheet (exterior glazing), a lamination interlayer and a second glass sheet (interior glazing) with two through-holes in this second sheet.

Laminated glass includes: a first glass plate having a rectangular shape, and including a first side and a second side opposing the first side; a second glass plate arranged opposing the first glass plate, and having substantially the same shape as the shape of the first glass plate; and an intermediate film arranged between the first glass plate and the second glass plate, the intermediate film including: a first bus bar extending along an end portion closer to the first side; a second bus bar extending along an end portion closer to the second side; and a plurality of heating lines arranged parallel to each other so as to connect the first bus bar and the second bus bar to each other.

A laminated glass comprising an outer glass sheet, an inner glass sheet, and an intermediate layer between the outer and inner glass sheets. The intermediate layer has a first busbar, a second busbar, and heating wires connecting the first and second busbars, and a sheet-like substrate supporting the heating wires. The intermediate layer further comprises an adhesive layer. A distance from a centre of the wires to a surface the outer glass sheet and a distance from the centre of the wires to a surface the inner glass sheet being different; and a distance from the centre of the wires to the inside surface of the outer glass sheet and a distance from the centre of the wires to the outside surface of the inner glass sheet being different, and the adhesive layer thickness or the substrate thickness, whichever is smaller, is not more than 400 micrometres.

A composite pane includes an outer pane and an inner pane which are joined to one another via a first thermoplastic intermediate layer arranged directly adjacent the outer pane and a second thermoplastic intermediate layer arranged directly adjacent the inner pane, and an inlay element which is arranged in a region of the composite pane between the first thermoplastic intermediate layer and the second thermoplastic intermediate layer. The inner pane has a cutout and the second thermoplastic intermediate layer has a cutout. The cutout of the second thermoplastic intermediate layer is, when looked through, arranged completely within the region in which the inlay element is arranged, and the cutout of the inner pane is, when looked through, arranged completely within the cutout of the second thermoplastic intermediate layer.

The present invention relates to glass for vehicles including a glass plate; an information transmitting/receiving area, defined in the glass, via which a device mounted in a vehicle transmits or receives information; and a film that heats the information transmitting/receiving area, the film being attached to an area overlapping the information transmitting/receiving area in an interior side of the glass plate in a vehicle in a planar view; wherein the film includes a substrate, a heating element formed on the substrate, and a busbar connected to the heating element; the film has a heating zone divided into two or more heating areas; and the two or more of the heating areas share at least one busbar and are connected in series.
