1.3 series airbags are mainly composed of sensors, microprocessors, gas generators and airbags.

2. Sensors and microprocessors are used to judge the collision degree and send signals.

3. The gas generator generates ignition action according to the signal indication, ignites the solid fuel and generates gas to inflate the airbag, so that the airbag expands rapidly, and the airbag volume is about (50-90) L. ..

4. The airbag is equipped with a safety valve. When it is inflated excessively or the pressure in the airbag exceeds a certain value, it will automatically release some gas to avoid squeezing passengers.

5. The gas used in the airbag is mainly nitrogen or carbon monoxide.

6. The gas used in the airbag is the gas produced by azide explosion, which does not contain carbon monoxide, mainly N2.

7. The sensor measures the acceleration. 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 is filled into the airbag.
