The effect of the triangular rear glass window of the car that many people do not know?
Most car models have triangular rear windows, so what is their function?
If you pay close attention, you can easily see that all car models have fixed triangular glass windows at the back. Fixed glass windows are the glass windows that cannot be adjusted to open/close or up/down. Depending on the model and design, each car can have 1 or 2 types of fixed glass windows.
According to car engineers, the small triangular fixed rear window has many little-known uses.
Increased visibility for drivers
Car manufacturers often install a small triangular window next to the A-pillar to avoid blind spots caused by the front windshield being tilted too much.
Although the triangular window is small, the driver can still observe the outside of the car through the glass and avoid collisions with obstacles in the blind spot of the viewing angle. If the triangular glass is removed from the car, the size of the A-pillar will be larger. At that time, the opaque A-pillar will block the driver's vision, making it difficult to observe the blind spots on the left and right through the front windshield.
Help ventilate
The triangular window dates back to 1950. At that time, the triangular window acted as a small window to let air in and out of the cabin. This type of window was very popular until air conditioning came along.
However, with the need to save gas, the purpose of using triangular glass for ventilation in cars is almost gone.
Reduce vibration
The design of the additional triangular frame next to the A-pillar is to increase stability and support. Thanks to the triangular window, the rigidity of the A-pillar is stronger, the structure of the car is also more reasonable.
The addition of the triangular window also increases the interior lighting area. However, because it has to fit inside the rear door, the window cannot open to its full size.
