What is the principle of the airbag inflator?

[MaryRose]

Working principle of the airbag inflator: After a vehicle collision, the sensor detects the deceleration signal and transmits it to the ECU. The ECU calculates and determines whether ignition is required. If ignition is necessary, the ECU sends an electrical signal command to the generator. The generator ignites and releases gas, which rapidly fills the airbag. The airbag then deploys to protect the occupants. Airbag: An airbag is a device that inflates to protect occupants before they experience a secondary collision during a crash. It consists of an integrated airbag module comprising the airbag and the inflator (gas generator), a collision sensor system that detects the collision and sends a deployment command to the airbag module, and wiring harnesses that transmit signals from the sensors. Precautions: Airbags must be used in conjunction with seat belts; maintain an appropriate distance from the airbag while seated; do not place items in front of, above, or near the airbag.
