Abstract

An object of the present disclosure is to provide a window glass for vehicle that prevents intensity of light to be used in optical equipment attached to a vehicle from being attenuated, and that is easier to handle while having a component unit. A window glass for vehicle comprises: a laminated glass including a vehicle inner glass plate, a vehicle outer glass plate and an interlayer film; and a component unit. A vehicle inner glass plate is cut-out at a portion of the periphery of the laminated glass, and in the portion, the component unit is arranged. A vehicle inner surface of the laminated glass fits on the flush with a vehicle inner surface of the component unit, at least in a region, on a boundary between the laminated glass and the component unit.

First claim

What is claimed is:

1. A window glass for a vehicle, comprising:
a laminated glass comprising (a) an inner glass plate located on an inner side of the vehicle when the laminated glass is attached to the vehicle, (b) an outer glass plate located on an outer side of the vehicle when the laminated glass is attached to the vehicle, and (c) an interlayer film between the inner glass plate and the outer glass plate, the inner glass plate and the outer glass plate being bonded via the interlayer film; and
a component unit comprising an optical component and a plate-shape member, wherein
the laminated glass comprises a cut-out region, where the inner glass plate has a cut-out portion at the periphery of the laminated glass and the outer glass plate is not cut out in the cut-out region of the laminated glass, the component unit is arranged on the inner side of the vehicle when the laminated glass is attached to the vehicle, the plate-shape member covers the cut-out portion of the laminated glass, an optical path of the optical component passes through the cut-region of the laminated glass and the plate-shape member, and
the plate-shape member has a shape at least in a region such that an inner surface of the laminated glass on the inner side of the vehicle when the laminated glass is attached to the vehicle fits flush with an inner surface of the plate-shape member on the inner side of the vehicle when the laminated glass is attached to the vehicle at least in a boundary region on a boundary between the laminated glass and the plate-shape member, the boundary region being a region where an adhesive is applied for attaching the window glass for vehicle to the vehicle.

2. The window glass according to claim 1 , wherein the laminated glass comprises a wiper wiping region of the window glass and the cut-out region of the laminated glass is within the wiper wiping region.

3. The window glass according to claim 1 , wherein
the plate-shaped member comprises a first portion comprising a resin capable of transmitting infrared rays, the first portion corresponding to the optical path of the optical component.

4. The window glass according to claim 3 , wherein the plate-shaped member further comprises a second portion comprising a colored resin, the second portion being other than the first portion.

5. The window glass for vehicle according to claim 3 , wherein the plate-shaped member further comprises a second portion comprising a metal, the second portion being other than the first portion.

6. The window glass for vehicle according to claim 5 , wherein the first portion has a shape at a boundary with the second portion being such that a vehicle-outer surface of the first portion fits flush with a vehicle outer surface of the second portion.
