General deployment of air bag
In general, the air bag unit transmits the ignition current to the ignition device of the corresponding air bag
inflator when a collision signal from the impact sensor is sent to the air bag unit
When the ignition device of the inflator is ignited, the gas generator generates nitrogen gas by being
burned, and this gas inflates the air bag cushion through the filter. The nitrogen gas used to inflate the air
bag exhausts through the vent hole immediately.
