The airbag is mainly composed of sensor, microprocessor, gas generator and airbag. The sensor and the microprocessor are used for judging the collision degree and sending signals; The gas generator generates an ignition action according to the signal indication, ignites the solid fuel and generates gas to inflate the airbag, so that the airbag expands rapidly.
In addition, the sensor detects the acceleration, and when the acceleration reaches a certain value, the microprocessor sends out an ignition signal to ignite the azide, so that the gas generated by the explosion fills the airbag. The airbag is just an auxiliary protective device. The airbag is made of special fabric nylon with rubber lining, and it is filled with harmless helium when working. The system is started by a sensor to monitor the deceleration of the car in the collision. At the beginning of the collision, the airbag began to inflate, and it took about 0.03 seconds to inflate safely.
