no. 1 Embodiment approach 〉
[0029] figure 1 Shown is a diagram illustrating a windshield for a vehicle according to the first embodiment, figure 1 (a) is a diagram schematically showing how the windshield can be recognized from the inside of the vehicle to the outside of the vehicle (the windshield 20 is attached to the vehicle with the Z direction upward). figure 1 (b) shows the figure 1 (a) is a cross-sectional view of the windshield 20 taken along the XZ direction and viewed from the Y direction. in addition, figure 1 In (b), the device 300 is shown together with the windshield 20 for convenience, but the device 300 is not a constituent element of the windshield 20 .
[0030] Such as figure 1 As shown, the windshield 20 is a vehicle glass having a glass plate 21 , a shielding layer 24 , and a film 25 .
[0031] In the windshield 20, the surface 21a (inner surface of the windshield 20) on the inner side of the glass plate 21 and the outer surface 21b (outer surface of the windshield 20) of the gla...
no. 2 Embodiment approach 〉
[0073] The second embodiment shows an example in which the method of dividing the heating region is different from that of the first embodiment. In addition, in the second embodiment, the description of the same components as those in the already described embodiment will be omitted.
[0074] Figure 4 Shown is a diagram illustrating the film of the second embodiment, and is a plan view schematically showing the form of the recognition film from the interior of the vehicle to the exterior of the vehicle. Cutaway view of the membrane with figure 2 (b) is the same, so illustration is omitted.
[0075]In the film 25A of the second embodiment, as an example, the heating element 252 is provided with four slits S1, S2, S3 and S4. And the heating element 252 is divided into five heating regions 252a1, 252a2, 252a3, 252a4, and 252a5 by the slits S1, S2, S3, and S4.
[0076] In the heating element 252, a bus bar 253d1 is connected along one end of the heating region 252a1, and a ...
no. 3 Embodiment approach 〉
[0084] The third embodiment shows an example in which the slits for dividing the heating regions are curved lines. In addition, in the third embodiment, the description of the same components as those in the already described embodiment will be omitted.
[0085] Figure 5 Shown is a diagram illustrating a film according to the third embodiment, and is a plan view schematically showing the form of the recognition film from the interior of the vehicle to the exterior of the vehicle. Cutaway view of the membrane with figure 2 (b) is the same, so illustration is omitted.
[0086] The film 25B of the third embodiment is different from the film 25 of the first embodiment in that the linear slits S1 and S2 are replaced by the curved (arc-shaped) slits C1 and C2. The upper end of the heating region 252a1 and the lower end of the heating region 252b are formed in a curved shape curved in the same direction as the slits C1 and C2.
[0087] In this way, even when the curved (arc-sha...
