Abstract
The present invention is a windshield on which an information acquisition device that acquires information from outside of a vehicle by emitting and/or receiving light can be arranged, the windshield including: an outer glass plate; an inner glass plate; an interlayer film arranged between the outer glass plate and the inner glass plate; and a mask layer laminated on at least one of a surface on a vehicle interior side of the outer glass plate and a surface on a vehicle exterior side of the inner glass plate, in which the interlayer film includes a colored shade region, a transparent non-shade region, and a transparent sheet member that is fitted into at least one through hole formed over the shade region and the non-shade region.
Claims22
A laminated glass on which an information acquisition device for acquiring information from outside of a vehicle by emitting and/or receiving light is arrangeable, the laminated glass comprising:
- an outer glass plate;
- an inner glass plate;
- an interlayer film arranged between the outer glass plate and the inner glass plate;
- and
- a mask layer laminated on at least one of a surface on a vehicle interior side of the outer glass plate or a surface on a vehicle interior side of the inner glass plate,
- wherein the interlayer film includes:
- a colored shade region;
- a transparent non-shade region;
- and
- a transparent sheet member fitted into at least one through hole formed over the shade region and the non-shade region,
- the mask layer includes at least one opening that is formed on an inner side relative to an edge portion of the sheet member at a position corresponding to the sheet member,
- the light of the information acquisition device passes through the opening,
- when a thickness between an outer surface of the outer glass plate and an inner surface of the inner glass plate at a central point of the sheet member is defined as H1, a thickness between the outer surface of the outer glass plate and the inner surface of the inner glass plate at a point that is 400 mm away from the edge portion of the sheet member on a virtual line extending in a horizontal direction through the central point is defined as H2, and
- any point A on an inner edge of the opening, a point B that is the shortest distance from the point A on an outer edge of the sheet member, and a point C at which a virtual line extending from the point A through the point B and an outer edge of the mask layer intersect each other,
- a distance between the point A and the point B is defined as S1, and a distance between the point B and the point C is defined as S2,
- when H1 is greater than H2, S1 is smaller than S2 at a location where S1+S2 is minimized,
- when H1 is less than H2, S1 is greater than S2 at a location where S1+S2 is minimized, and
- |H1-H2|≥120 μm.
