example 1

[0040] image 3 It is the result of measuring the attenuation of radio waves when the height and lateral width of the electromagnetic wave transmitting part of the window glass for automobiles are changed during the transmission and reception process after the mobile phone for PCS is installed on the center console . Three types of window glass having the heights of the electromagnetic wave transmitting portion of 190 mm, 170 mm, and 130 mm were prepared, and the width of the electromagnetic wave transmitting portion was changed for measurement. The lateral width of the electromagnetic wave transmitting portion refers to the distance L along the glass surface between the longitudinal inner side of the inside of the window glass 101 of the electromagnetic wave transmitting portion 105 and the front end portion 121a of the vehicle body flange 121 located on the side (see figure 1 ). The height of the electromagnetic wave transmitting portion refers to the distance H along the ...

example 2

[0044] Such as Figure 4 As shown, an automobile window glass with an infrared shielding part on the automobile window glass was prepared, and the receiving performance of the receiver of the TPMS tire pressure sensor built in the rear pillar of the vehicle was tested. The lower end portion of 101 is not formed with an infrared shielding portion, but is provided with an electromagnetic wave transmitting communication portion 106 that communicates with the electromagnetic wave transmitting portions 105 on both sides in the vehicle width direction.

[0045] For a plurality of window glasses for automobiles in which the height of the electromagnetic wave transmission communication portion is changed, the reception rate when the tire is rotated once is calculated and measured, respectively. The height of the electromagnetic wave transmission communicating portion refers to the distance T between the upper edge of the electromagnetic wave transmitting communicating portion 106 and ...

Abstract

The present invention relates to a window glass for a vehicle, attached to a body flange of the vehicle at a circumferential edge portion thereof, including: an infrared ray shielding portion which reflects or absorbs infrared rays on a large part of the window; and electromagnetic wave transmitting portions having a substantially rectangular shape, which transmit at least a predetermined electromagnetic wave, at each of lower end portions on both sides in a width direction of the vehicle.

Description

technical field [0001] The present invention relates to a window glass for automobiles, in particular to a window glass for automobiles with infrared shielding performance. Background technique [0002] In recent years, in order to reduce the cooling load by suppressing the temperature rise in the automobile, the use of glass having infrared shielding performance (hereinafter sometimes referred to as infrared shielding glass) for vehicle window glasses has become popular. As a conventional infrared shielding glass, a glass plate with a film is used, in which a conductive film of various metals or metal oxides is laminated on the surface of the glass plate. The function of these films can greatly reduce the radiation incident into the car interior. Solar radiant energy. [0003] However, it is known that this infrared shielding glass not only shields infrared rays, but also acts as a factor that blocks radio waves of mobile phones. Furthermore, in the United States, it is o...
