The full airbag is used as a key component of an occupant restraint system and is matched with a seat belt for use, so that effective anti-collision protection can be provided for an occupant, and the full airbag is widely arranged on a passenger car. Plays an extremely critical role in protecting passengers in the event of a collision of automobiles. When the automobile collides, the safety airbag is ensured to be capable of instantly receiving an ignition signal transmitted by the safety airbag controller and being instantly unfolded, and the safety airbag is ensured to be correct in form in the unfolding process of the safety airbag, so that a good passenger protection effect is achieved. Curtain airbags, also known as side curtains or head airbags, are generally installed in the roof on both sides of a vehicle, mainly for protecting the head of an occupant in the vehicle from the side, and are particularly effective in the event of a vehicle crash and rollover.
The airbag system is composed of an integral airbag module composed of an airbag and an inflation mechanism (gas generator), a collision sensor and an airbag control unit system which sense collision and send out a deployment instruction to the airbag module, and a wire harness which transmits a collision ignition signal.

3. the firing of existing curtain airbags is typically commanded by an airbag control controller located under the vehicle's fascia. The wiring harness from the ceiling to the auxiliary instrument panel is long in connection distance and is subjected to multiple switching, and after the vehicle is used for a long time, faults such as short circuit, open circuit, poor contact and the like can possibly occur in the ignition circuit connection wiring harness. Once the safety airbag fails, the safety airbag can not detonate, and potential safety hazards are brought to passengers.
