  • Publication number: 20220418050
    Abstract: Laminated glass includes: an outer glass plate having a first side and a second side; an inner glass plate that is arranged opposing the outer glass plate and has substantially the same shape as a shape of the outer glass plate; and an intermediate layer arranged between the outer and the inner glass, wherein the intermediate layer has a heat-generating layer including: a first bus bar that extends along an end portion closer to the first side; a second bus bar that extends along an end portion closer to the second side; and a plurality of heating lines arranged so as to connect the first bus bar and the second bus bar to each other, and when a predetermined voltage is applied between the first and second bus bars, an amount of heat generated per unit length of each of the heating lines is 2.0 W/m or less.

  • Patent number: 10336163
    Abstract: A windshield according to the present invention is a windshield to which an information acquisition device that emits and/or receives light to acquire information from an outside of a vehicle can be attached, and that includes a glass sheet, and a mask layer that is formed on the glass sheet and blocks a visual field from the outside of the vehicle, and at least one opening is formed in the mask layer. The glass sheet and the mask layer have different heat shrinkage percentages and are molded together by being heated. The information acquisition device is configured to be capable of using the information while reducing an influence of distortion that occurs in a predetermined range from an inner peripheral edge of the opening toward a center of the opening due to the molding.
