"Triangle is the most stable shape." This should be the basic knowledge for everyone. Triangles have the characteristics of stability, firmness and pressure resistance, and triangles are all around our daily life.

There is an indispensable triangular design on the car, which is the triangular window. However, many car owners don't know the real function, they only know that it is a component of the car. What is the function of the triangular window on the car? At the beginning of the design, the triangular window was not for the consideration of drivers vision, but mainly for ventilation. In the 1840s, even household air conditioners were not popular, so triangular windows were developed. At that time, triangular windows were able to be opened, which is why it had the charactersitic a window. After the 1960s, with the applications of vehicle air conditioners and sunroofs, the ventilation problem was better resolved, and the functional triangular windows were gradually eliminated and given new functions.

1. The triangular window on the A-pillar:

When driving a vehicle, a wide field of vision is very important, to ensure driving safety. The triangle window in front of the car is designed to increase the visual field and effectively reduce the blind spot area of visual field. Without this triangular window design, there will be more blind spots, ultimately obstructing the drivers view.

2. The triangular window on the back door:

Aesthetically, the triangular window on rear doors can make the overall shape more beautiful and harmonious. Some rear doors are too long. If the rear doors and windows are made into a whole piece, the windows can't descend into the door panel. Therefore, a part of the glass is removed from the triangular window, which makes it easier and smoother for the glass to rise and fall. Meanwhile, the vision of passengers and the light transmittance in the car are increased.

3. The triangular window on the C-pillar:

The lighting in the back row is not as good as that in the front row. The triangular windows on the C-pillar allow the passengers in the back row to feel more spacious, and increase their vision. At the same time, the triangular structure can also increase the strength and stabilize the C-pillar structure.

The triangular window is actually the most expensive window glass due to its production difficulty. When the car keys are left in the car and need to be uinlocked by breaking a window, never choose triangular windows. Additionally, to ensure vision and driving safety, try not to choose dark window tinting film for the front triangular windows and the front doors and windows.
