Definitions

  • thin conductive metallic wires may be embedded in the laminate, in contact with the interlayer and more particularly at least partially embedded in the interlayer, and contacting one of the inner face of one of the glass sheets.
  • Such wires are used to heat the windshield (resistance heating by Joules effect) for defrosting and defogging.
  • These wires may be made very thin, so as to minimize intrusion into the driver's field of view, and run from side to side or vertically along the windshield, following usually sinusoid-like paths such as described in EP3191303B1. They can also follow a snake path.
  • Heatable wired glazings are well known from skilled man in the art.
  • a laminated glazing is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by a thermoplastic interlayer, typically of polyvinyl butyral (PVB), ethylene-vinyl acetate (EVA) or polyurethane (PU), between its two or more layers of glass.
  • PVB polyvinyl butyral
  • EVA ethylene-vinyl acetate
  • PU polyurethane
  • the flat connector comprises, on its part covering partially the external face of the internal glass sheet, a control circuit configured to control the embedded conductive wires.
  • the flat connector further comprises, on its part covering partially the external face of the internal glass sheet, an active regulation system configured to be connected to a battery of the vehicle.
  • the flat connector further comprises, on its part at least partially embedded between the interlayer and the external glass sheet or the internal glass sheet, at least one thermistor. The thermistor is connected to the control circuit through the flat connector.
  • Fig.lb, Fig.lc, Fig.ld and Fig.le illustrate alternative embodiments of a heatable wired laminated glazing according to the invention, viewed from the side.
  • the glazing is configured to be placed in front of an optical sensor.
  • An optical sensor is understood as a sensor which has at least a receiver active in the ultraviolet, visible or infrared wavelength, such as a camera or a rain sensor. It can also further comprise an emitter active in the ultraviolet, visible or infrared wavelength, such as a lidar.
  • the glazing is a part of an exterior trim element.
  • An exterior trim element includes bumper, window/door seal, wheel well, fender, headlight, mirror body and roof cover. Vehicle manufacturers use these exterior trim elements to add aesthetics, increase function, and add flexibility to the vehicle design.
  • the flat connector (3) further comprises, on its part covering partially the external face (13e) of the internal glass sheet (13), an active regulation system (5), such as a DC-DC converter.
  • the active regulation system (5) is connected to a battery of the vehicle (not shown).
