Airbags (SRS)
This system is a common passive safety device on domestic and foreign automobiles. When the vehicle collides, the nitriding material in the airbag placed in the center of the steering wheel (some on the dashboard, behind the glove box) is detonated by the electric control element with electric current, and it burns rapidly to generate nitrogen, which fills the airbag instantly. The function of the airbag is to form a cushioning cushion between the driver and the steering wheel, and between the front seat occupant and the instrument panel, so as to avoid injury due to hard impact. This device must be used in conjunction with the seat belt, otherwise the effect will be greatly reduced.
