What Is a Head Crash?
The head airbag, also known as the curtain airbag CAB, is installed on the top of the car to protect the head of the occupant from the side. It usually consists of an air bag, an air bag cloth, a gas generator, a gas generator support, and a catheter.

- The head airbag, also known as the curtain airbag CAB, is installed on the top of the car to protect the head of the occupant from the side. It usually consists of an air bag, an air bag cloth, a gas generator, a gas generator support, and a catheter.
- The head airbag, also called a side air curtain, pops up to cover the window during a collision, preventing the front passenger's head from directly hitting nearby hard parts, buffering the lateral displacement of the head and inertia, and protecting the cervical spine and head safety. The front head airbags are usually located on the steel beams (inside) on both sides of the windshield. It should be noted that only when the airbag is matched with the seat belt can the passenger be best protected in a major accident.
- The curtain airbag (CAB) is used to protect the head of the occupant in a side collision. The CAB component assembly is composed of an air bag, an air bag cloth, a gas generator, a gas generator bracket and a catheter. When the car has a side collision and meets the conditions that the airbag should be deployed, the CAB module is designed to be deployed above the occupant's head. The air belt inside the module is deployed due to internal pressure. The air belt is deployed at a fixed position to protect the occupant's head. unit.
- Car airbags contain substances such as sodium azide (NaN3) or ammonium nitrate (NH4NO3). When a car is hit violently at high speeds, these substances will quickly decompose and generate a large amount of gas, which will fill the airbag.
- As a passive safety device, airbags have been widely recognized for their protective effects. The first patent on airbags began in 1958. In 1970, manufacturers began to develop airbags that could reduce the degree of occupant injury in collision accidents. In the 1980s, automobile manufacturers began to gradually install airbags. In the 1990s, the use of airbags increased sharply; and into the new century In the future, airbags will generally be installed on cars. Since the introduction of the airbag, many lives have been saved. Studies have shown that cars with airbags have a frontal collision, and the death rate of drivers has been reduced by 30% for large cars, 11% for medium cars and 20% for small cars. [1]
