Abstract

A front quarter glass includes a window plate, a frame-like black ceramic layer on a peripheral portion of an interior side surface, and an anti-fogging film provided in a region excluding an entire peripheral portion of the window plate. A boundary is between the regions where the anti-fogging film is provided and not provided, has no perspective distortion, and has a boundary line of 10-200 μm that is visually recognized by scattering of incoming light. An outer periphery of the anti-fogging film is located is located 8 mm (0.31 inch) inside from an inner periphery of the black ceramic layer in a first region. The first region is to less than 50% of an entire inner periphery including a lower front portion. The outer periphery of the anti-fogging film is located 8-35 mm (0.31-1.38 inches) inside the inner periphery of the black ceramic layer in a second region excluding the first region.

Claims

1. A vehicle front quarter glass, comprising:

a window plate;

a frame-shaped black ceramic layer provided in a peripheral portion of a vehicle interior side surface of the window plate as viewed in a front view; and

an anti-fogging film provided in a region excluding an entirety of the peripheral portion of the window plate as viewed in the front view, wherein

a boundary between the region where the anti-fogging film is provided and a region where the anti-fogging film is not provided has no perspective distortion and is formed by a boundary line having a linewidth of 10-200 μ

m (0.000393701-0.00787402 inches), the boundary line being visually recognized by scattering of incoming light,

an outer periphery of the anti-fogging film is located on an outer side of a position that is located 8 mm (0.31 inch) inside from an inner periphery of the black ceramic layer in a first region, the first region including an area of the inner periphery of the black ceramic layer that is located in a lower front portion thereof when the vehicle front quarter glass is installed in a vehicle, the first region corresponding to less than 50% of an entire inner periphery of the black ceramic layer, and

the outer periphery of the anti-fogging film is located 8-35 mm (0.31-1.38 inches) inside from the inner periphery of the black ceramic layer in a second region, the second region being the entire inner periphery of the black ceramic layer excluding the first region.

2. The vehicle front quarter glass according to claim 1, wherein the outer periphery of the anti-fogging film includes no corner portion having an interior angle of no more than 90 degrees.

3. The vehicle front quarter glass according to claim 1, wherein the outer periphery of the anti-fogging film includes a corner portion having an interior angle of no more than 90 degrees.

4. The vehicle front quarter glass according to claim 1, wherein the outer periphery of the anti-fogging film is located 8-20 mm (0.31-0.79 inches) inside from the inner periphery of the black ceramic layer in the second region.

5. The vehicle front quarter glass according to claim 1, wherein the first region is a region corresponding to no less than 1% of the entire inner periphery of the black ceramic layer.

6. The vehicle front quarter glass according to claim 1, wherein a region including a region corresponding to the lower front portion of the inner periphery of the black ceramic layer includes an overlapping region of the anti-fogging film and the black ceramic layer in which the outer periphery of the anti-fogging film coincides with the inner periphery of the black ceramic layer or the outer periphery of the anti-fogging film is located on an inner side of an outer periphery of the black ceramic layer and on an outer side of the inner periphery of the black ceramic layer.

7. The vehicle front quarter glass according to claim 6, wherein the overlapping region corresponds to 5-20% of the entire inner periphery of the black ceramic layer.
