What is the principle of airbag deployment?

[OMiranda]

The working principle of an airbag is that during vehicle movement, if the acceleration, rate of velocity change, or other indicators measured by the sensor system exceed predetermined values (indicating an actual collision), the control device sends an ignition command to the gas generator, or the sensor directly controls ignition. Upon ignition, an explosive reaction occurs, generating N2 or releasing compressed nitrogen from a storage tank to inflate the collision airbag. Note: Airbags distribute the impact force evenly across the head and chest, preventing fragile passengers from direct contact with the vehicle body and significantly reducing the likelihood of injury. Airbags are indeed effective in protecting passengers during frontal collisions, and even without seat belts, the anti-collision airbag is sufficient to effectively reduce injuries.
