Abstract
A colliding object is suppressed from reaching a driver's seat, and an occupant and an object in a vehicle compartment are suppressed from being thrown out of a vehicle. In a vehicle glass 1, a far-infrared transmitting region in which an opening portion and a far-infrared transmissive member 20 arranged in the opening portion are provided is formed in a light shielding region. The vehicle glass 1 includes a protective member 40 that is provided on a vehicle interior side of the far-infrared transmissive member 20 and overlaps with at least a part of the far-infrared transmissive member 20 when viewed from a direction orthogonal to a vehicle exterior side surface 20a of the far-infrared transmissive member 20.
Claims20
A vehicle glass comprising:
- a light shielding region,
- wherein a far-infrared transmitting region in which an opening portion and a far-infrared transmissive member arranged in the opening portion are provided is formed in the light shielding region, and
- the vehicle glass further comprises a protective member that is provided on a vehicle interior side of the far-infrared transmissive member and overlaps with at least a part of the far-infrared transmissive member when viewed from a direction orthogonal to a vehicle exterior side surface of the far-infrared transmissive member,
- wherein the far-infrared transmissive member comprises a base material comprising at least one selected from the group consisting of Si, Ge, ZnS, and chalcogenide glass;
- and
- wherein the protective member comprises a material having a higher breaking strength than the far-infrared transmissive member.
A vehicle glass manufacturing method comprising:
- boring an opening portion that penetrates through each of a first glass substrate and a second glass substrate in a thickness direction;
- chamfering a boundary portion between the opening portion and a vehicle interior side surface of the first glass substrate, a boundary portion between the opening portion and a vehicle exterior side surface of the first glass substrate, a boundary portion between the opening portion and a vehicle interior side surface of the second glass substrate, and a boundary portion between the opening portion and a vehicle exterior side surface of the second glass substrate;
- positioning the opening portion of the first glass substrate and the opening portion of the second glass substrate, and then bonding the first glass substrate and the second glass substrate with an intermediate layer interposed therebetween to obtain a laminated glass;
- installing a far-infrared transmissive member in the opening portion;
- and
- installing a protective member overlapping with at least a part of the far-infrared transmissive member when viewed from a direction orthogonal to a vehicle exterior side surface of the far-infrared transmissive member on a vehicle interior side of the far-infrared transmissive member,
- wherein the far-infrared transmissive member comprises a base material comprises at least one selected from the group consisting of Si, Ge, ZnS, and chalcogenide glass, and
- wherein the protective member comprises a material having a higher breaking strength than the far-infrared transmissive member.
A vehicle glass comprising:
- a light shielding region,
- wherein a far-infrared transmitting region in which an opening portion and a far-infrared transmissive member arranged in the opening portion are provided is formed in the light shielding region, and
- the vehicle glass further comprises a protective member that is provided on a vehicle interior side of the far-infrared transmissive member and overlaps with at least a part of the far-infrared transmissive member when viewed from a direction orthogonal to a vehicle exterior side surface of the far-infrared transmissive member, wherein:
- the far-infrared transmissive member comprises a base material comprises at least one selected from the group consisting of Si, Ge, ZnS, and chalcogenide glass;
- and
- the protective member comprises a surface portion overlapping with the far-infrared transmissive member, a protruding portion, and a fixing portion, and is fixed, via the fixing portion, to a vehicle interior side surface of the vehicle glass via an adhesive layer.
