Problems solved by technology

[0003]However, in laminated glass with linear components, light may be diffracted by linear components, and optical effects such as iridescence or light may occur
These optical effects can be uncomfortable for the driver of the vehicle and are undesirable from a safety point of view

no. 1 Embodiment approach 〉

[0030] figure 1 Shown is a figure (part 1) illustrating a windshield for a vehicle according to the first embodiment, figure 1 (a) is a diagram schematically showing how the windshield is recognized from the interior of the vehicle to the exterior of the vehicle. figure 1 (b) is shown along the figure 1 Partially enlarged cross-sectional view of line A-A in (a).

[0031] figure 1 In the figure, for convenience of description, the actual curved shape is omitted and the windshield 20 is shown as a plane. In addition, in the following description, the symbol 20 1 Referred to as the upper edge of the windshield 20, the symbol 20 2 called the lower edge part, the symbol 20 3 called the left edge portion, the symbol 20 4 called the right edge. Here, when the windshield 20 is attached to a right-hand drive vehicle (the steering wheel is placed on the right), the upper edge portion refers to the edge portion on the roof side of the vehicle, the lower edge portion refers to the...

[0110] In the second embodiment, an example is shown in which electric power is supplied to the linear member of the conductive heating element from the vertical direction. In addition, in the second embodiment, the description of the same components as those in the already described embodiment may be omitted.

[0111] Figure 6 Shown is a diagram illustrating a windshield for a vehicle according to the second embodiment, and is a diagram schematically showing how the windshield is recognized from the interior of the vehicle to the exterior of the vehicle.

[0112] Such as Figure 6 As shown, in the windshield 20A, the first bus bar 31 runs along the right edge portion 20 of the windshield 20 4 , upper edge portion 20 1 and left edge part 20 3 Arranged continuously, the second bus bar 32 runs along the lower edge portion 20 of the windshield 20 2 configuration.

[0113] The first bus bar 31 and the second bus bar 32 are connected to each linear member of the conductive h...

Abstract

A laminated glass of the present invention is provided with a pair of glass plates which face each other, an intermediate film arranged between the pair of glass plates, and a plurality of linear members which can heat transparent regions in the pair of glass plates and are arranged in parallel, wherein the width of each of the linear members is 2 to 30 um inclusive, and the line width is not constant in at least a part of the plurality of linear members.

Description

technical field [0001] This invention relates to laminated glass. Background technique [0002] It is known that a laminated glass in which a conductive heating element including a plurality of linear members is sandwiched between a pair of glass plates can be used as a window glass for automobiles or railway vehicles. This laminated glass can remove the fog of the window glass by heating the conductive heating element, and prevent the freezing of moisture attached to the window glass in winter. [0003] However, in laminated glass with linear members, light may be diffracted by the linear members, and optical effects such as iridescence or light may occur. These optical effects can be uncomfortable for the driver of the vehicle and are undesirable from a safety point of view. Then, in order to suppress the optical effect by the diffracted light by a linear member, various proposals are made (for example, refer patent document 1). [0004] prior art literature [0005] p...
