Abstract

Provided are a vehicle windshield equipped with a transparent film at a visual field area, where a negative effect on a driving visibility due to a boundary line between a forming area and a non-forming area of the transparent film is improved, and a vehicle component having the vehicle windshield. The vehicle windshield includes: a window plate; and a transparent film provided at a surface on a vehicle-interior side of the window plate, wherein the vehicle windshield includes a first area where the transparent film is not provided and a second area where the transparent film is provided, at a central area when viewed from a front side, and a boundary between the first area and the second area has no perspective distortion and is constituted by a boundary line having line width visually recognized by scattering of irradiated light of 10 μm to 200 μm.

Claims

1. A vehicle windshield, comprising:

a window plate; and

a transparent film provided at a surface on a vehicle-interior side of the window plate,

wherein the vehicle windshield includes a first area where the transparent film is not provided and a second area where the transparent film is provided, at a central area when viewed from a front side, and

a boundary between the first area and the second area has no perspective distortion and is constituted by a boundary line having line width visually recognized by scattering of irradiated light of 10 μ

m to 200 μ

m.

2. The vehicle windshield according to claim 1,

wherein the first area of the vehicle windshield is located diagonally above when viewed from a driver when the vehicle windshield is mounted on a vehicle.

3. The vehicle windshield according to claim 1,

wherein at least a part of the boundary line is provided along at least a part of an upper side of the window plate of the vehicle windshield.

4. The vehicle windshield according to claim 1,

wherein a whole of the boundary line is provided along the upper side of the window plate of the vehicle windshield.

5. The vehicle windshield according to claim 3,

wherein the line width of the boundary line differs according to a position in a vehicle width direction.

6. The vehicle windshield according to claim 1,

wherein the transparent film is an antifogging film containing at least one kind selected from the group consisting of an epoxy resin, a urethane resin, and an acrylic resin.

7. The vehicle windshield according to claim 1,

wherein a film thickness of the transparent film becomes thicker toward a lower part.

8. The vehicle windshield according to claim 1,

wherein the window plate includes a light-shielding area at a peripheral part.

9. The vehicle windshield according to claim 8,

wherein a part of an end part of the transparent film is formed to overlap with the light-shielding area.

10. The vehicle windshield according to claim 1,

wherein the window plate includes a first light transmissive substrate, a second light transmissive substrate facing the first light transmissive substrate, and an interlayer sandwiched between the first light transmissive substrate and the second light transmissive substrate.

11. The vehicle windshield according to claim 1,

wherein the boundary between the first area and the second area is constituted by a boundary line whose line width visually recognized by scattering of irradiated light is 10 μ

m to 150 μ

m.

12. A vehicle component, comprising:

a vehicle windshield including a window plate and a transparent film provided at a surface on a vehicle-interior side of the window plate; and

a sensor acquiring information from a vehicle front side through the vehicle windshield,

wherein the vehicle windshield includes a first area where the transparent film is not provided and a second area where the transparent film is provided, at a central area when viewed from a front side,

a boundary between the first area and the second area has no perspective distortion and is constituted by a boundary line having line width visually recognized by scattering of irradiated light of 10 μ

m to 200 μ

m, and

the sensor is attached to the vehicle-interior side of the second area of the vehicle windshield.

13. A vehicle windshield, comprising:

a window plate;

a light-shielding area provided at a peripheral part of the window plate; and

a transparent film provided at a surface on a vehicle-interior side of the window plate,

wherein the light-shielding area includes a sensor light transmission area which is cut out into a shape whose periphery is surrounded by the light-shielding area, at least a part of the transparent film is provided such that a whole outer periphery is located in the sensor light transmission area, and an end part of the transparent film provided at the sensor light transmission area has no perspective distortion and is constituted by a boundary line having line width visually recognized by scattering of irradiated light of 10 μ

m to 200 μ

m.
