AI Technical Summary
Conventional sun visors only provide protection against backlight from the front, failing to address side illumination from the left and right, and require adjustments in car manufacturing to accommodate rearview mirror positioning.
A foldable three-sided backlight prevention board is attached to the driver's seat, incorporating protection plates on both sides and a rearview mirror adjustment for comprehensive backlight shielding.
The device effectively blocks backlight from all directions, enhancing driving comfort by minimizing glare from multiple angles, and can be easily installed in new and existing vehicles with model-specific adjustments.

Abstract
Description
[Technical Field]
[0001] This device is a sun visor that has foldable protection plates attached to both ends of a conventional ordinary sun visor, so that it can block backlight not only in front of the driver's seat but also on the left and right sides. [Technical Field]
[0002] To improve protection from backlight in front and on both sides, lower the rearview mirror located in the center of the ceiling in front of the driver's seat as far back as possible. [Technical Field]
[0003] When backlight protection is not required while driving, the mask can be attached to the ceiling. TIFF0003252493000002.tif12143This is a sun visor that can be easily operated and temporarily stopped. [Technical Field]
[0004] Conventional sun visors only had one location (one surface) at the top front of the driver's seat, so they could only protect against backlight from the front. Therefore, this device is a foldable three-sided backlight prevention board that is designed to prevent backlight not only from the front but also from the left and right.
[0005] With conventional sun visors that only cover the front of the vehicle, the surrounding scenery changes while driving, and the sunlight filtering through the trees, as well as the angle of the vehicle and backlighting, such as sunlight and street lighting, change. This is a device that was devised to solve these problems.
[0006] In the new car manufacturing process, depending on the model, it is necessary to lower the mounting position of the rearview mirror as far back as possible, and this needs to be incorporated into the new car manufacturing process. Used cars, etc. When installing the proposed sun visor on an existing car, care must be taken depending on the car model, whether large or small, type, and shape. [Brief explanation of the drawings]

Claims
1. This backlight prevention board has folding plates attached to both sides, making it possible to protect against backlight from both the left and right sides. This backlight prevention plate has been designed to be compatible with both right-hand drive and left-hand drive vehicles, and by contrasting left-hand drive vehicles with right-hand drive vehicles, it can be used with both left- and right-hand drive vehicles.
2. The backlight prevention plate previously only prevented backlight from the front, but the plate of this invention has been devised so that it can also prevent backlight from both the left and right directions. To achieve this, in order to improve the backlight prevention effect, it is necessary to move the position of the rearview mirror in the center of the ceiling in front of the driver's seat backward and lower it as far back as possible like the backlight prevention plate (attached diagram: A, B, C). In the case of a right-hand drive vehicle, backlighting can be prevented by making A, B, and C symmetrical in the same way as in the case of a left-hand drive vehicle.
3. This backlight prevention plate must be installed during the new car manufacturing process, and it is desirable that it be incorporated into the new car manufacturing process. (This applies to both left- and right-hand drive vehicles.) When installing it on an existing car, the installation position must be lowered backward compared to the conventional backlight prevention plate.
