  • Publication number: 20220072829
    Abstract: Laminated glass for a vehicle front window includes a curved first glass plate having a trapezoidal or rectangular shape; a second glass plate having the same shape as the first glass plate; and an intermediate film disposed between the first and second glass plates. An imaging section of an image projected from an imaging device incorporated in a dash board on a driver's seat side is included in an indoor side surface of the laminated glass in a state in which the laminated glass is incorporated in a vehicle body. The intermediate film is provided with a wedge angle profile in a longitudinal direction and a horizontal direction of the laminated glass, and a thickness based on the wedge angle profile of the intermediate film based on the wedge angle profile continuously decreases from an upper side to a lower side and continuously decreases in a direction from a driver's seat side to a passenger seat side.

The laminated glass includes an imaging section of an image projected from an imaging device incorporated in a dash board on a driver's seat side in an indoor side surface of the laminated glass. The intermediate film has a wedge angle profile with a thickness continuously changing in all 360° directions in observation when an upper longitudinal direction from the imaging section is set to 0°, and has a thickness of the intermediate film based on the wedge angle profile continuously decreasing from an upper side to a lower side and continuously decreasing in the horizontal direction from the driver's seat side to the passenger seat side.

  • Patent number: 10696582
    Abstract: To provide a vehicle window glass which is not susceptible to cracks, and a method for manufacturing the vehicle window glass. A vehicle window glass 1 of the present invention is provided with: a glass plate 11; a color ceramic layer 12, which is formed on the surface of the glass plate 11, and has a thickness more than 10 ?m but equal to or less than 25 ?m; and an electrically conductive layer 13, which is formed on the surface of the color ceramic layer 12, and has silver as a main component. The electrically conductive layer 13 and a terminal electrically connected to the electrically conductive layer 13 are connected to each other using a lead-free solder 14. In the vehicle window glass 1 of the present invention, since the thickness of the color ceramic layer 12 is more than 10 ?m, the glass plate 1 is not susceptible to cracks.
