2. The ignition of the initiator causes the ignition of the gas-generating agent. The section of the wall from which the air bag deploys is broken by this impact wave.
3. The charged gas and the gas generated by the gas-generating agent mix and pass through the orifice.
4. The combined gas, which passed though the orifice, is sprayed into the air bag through the diffuser (diffusion devise).
5. When the curtain air bag module operates (deploys), the air bag operates (deploys) while breaking open the A-pillar trim and headliner by the force of the combined gas sprayed out of the inflator.
