Abstract

A window glass with a seal member mounted to an opening of a vehicle includes a laminated glass including a vehicle outside glass plate, a vehicle inside glass plate, and an intermediate film; and a seal member arranged in a peripheral portion of the laminated glass. A plate thickness of the vehicle inside glass plate is less than that of the vehicle outside glass plate, and 1.0 mm or less. The vehicle outside glass plate has a shielding layer in a peripheral portion of a vehicle inside surface. In a cross section of the laminated glass perpendicular to an outer peripheral edge, an end of the vehicle inside glass plate is located inward in an in-plane direction with respect to an end of the vehicle outside glass plate. The seal member has a first fixing part that is bonded to the vehicle outside glass plate via the shielding layer.

Claims

1. A window glass with a seal member mounted to an opening of a vehicle comprising:

a laminated glass including a vehicle outside glass plate, a vehicle inside glass plate, and an intermediate film interposed between the vehicle outside glass plate and the vehicle inside glass plate; and

a seal member arranged in at least a part of a peripheral portion of the laminated glass,

wherein a plate thickness of the vehicle inside glass plate is less than a plate thickness of the vehicle outside glass plate, and 1.0 mm or less,

wherein the vehicle outside glass plate has a shielding 1.5 layer in a peripheral portion of a vehicle inside surface of the vehicle outside glass plate,

wherein in a cross section of the laminated glass perpendicular to an outer peripheral edge of the laminated glass, within at least a part of the outer peripheral edge of the laminated glass, an end of the vehicle inside glass plate is located inward in an in-plane direction with respect to an end of the vehicle outside glass plate, and

wherein the seal member has a first fixing part that is bonded to the vehicle outside glass plate via the shielding layer.

2. The window glass with a seal member according to claim 1,

wherein the vehicle inside glass plate contacts an interior member of the vehicle on a vehicle inside surface of the vehicle inside glass plate, and

wherein an end of the vehicle outside glass plate, an inner end of the first fixing part, an end of the vehicle inside glass plate, an inner end of the interior member, and an inner end of the shielding layer are arranged in this order inward in the in-plane direction with respect to the outer peripheral edge.

3. The window glass with a seal member according to claim 1,

wherein the seal member has a second fixing part bonded to the peripheral portion of the vehicle inside surface of the vehicle inside glass plate.

4. The window glass with a seal member according to claim 3,

wherein an area of a region where the second fixing part is bonded to the vehicle inside glass plate is smaller than an area of a region where the first fixing part is bonded to the vehicle outside glass plate on the shielding layer.

5. The window glass with a seal member according to claim 3,

wherein the vehicle inside glass plate contacts the interior member of the vehicle on the vehicle inside surface of the vehicle inside glass plate, and

wherein the end of the vehicle outside glass plate, the end of the vehicle inside glass plate, an inner end of the second fixing part, the inner end of the interior member, and the inner end of the shielding layer are arranged in this order inward in the in-plane direction with respect to the outer peripheral edge.

6. The window glass with a seal member according to claim 1,

wherein the plate thickness of the vehicle outside glass plate is 2.2 mm or less.

7. The window glass with a seal member according to claim 1,

wherein the vehicle inside glass plate is chemically tempered.
