Airbag Deployment Sequence

  1. When the impact threshold for the passenger airbag is exceeded an electric pulse (firing pulse) is sent from the ORC to the squib in the initiator.
  2. The squib ignites the solid propellant in the initiator. The solid propellant burns, developing a gas which flows explosively under high pressure into the airbag.
  3. Under the pressure of the gas, the airbag rips open the airbag housing, blows the airbag flap out of the instrument panel and inflates in the passenger compartment.
  4. After approximately 50 ms. the airbag reaches its maximum volume.
  5. After reaching the maximum volume, the pressure in the airbag starts decreasing. The gas escapes from the airbag through a filter and the airbag deflates.
NOTE: Typically, both initiators are used during an airbag deployment event. However, it is possible for only one initiator to be used during a deployment due to an airbag system fault; therefore, it is necessary to always confirm that both initiators have been used in order to avoid the improper disposal of potentially live pyrotechnic materials.
