PASSENGER AIRBAG
DESCRIPTION
The surface of the instrument panel top pad above the glove box is the most visible part of the passenger airbag.
The passenger airbag door is concealed behind the instrument panel top pad and above the glove box opening on
the instrument panel in front of the front seat passenger seating position.
The passenger airbag unit used in this model is a mul-
tistage,
Next
Generation-type
that
complies
with
revised federal airbag standards to deploy with less
force than those used in some prior models. The pas-
senger airbag unit consists of an extruded aluminum
housing, two stamped steel end brackets, a molded
plastic inner airbag cushion cover, the rectangular fab-
ric airbag cushion, and the airbag inflator. The airbag
housing contains the airbag inflator, while the inner
cover contains the folded airbag cushion. The inner
cover completely encloses the airbag cushion and is
permanently retained to the housing. The airbag cush-
ion is constructed of a coated nylon fabric. The airbag
inflator is a dual-initiator, hybrid-type unit that is
secured to and sealed within the airbag housing.
Note: The passenger airbag cannot be repaired,
and must be replaced if deployed, faulty, or in any
way damaged. The passenger airbag door is ser-
viced only as a unit with the instrument panel top
pad. If the passenger airbag is deployed, the instrument panel top pad must also be replaced. If inspection
reveals that the passenger airbag mounting points on the instrument panel structural duct have been
cracked or damaged by the deployment event, the instrument panel structural duct assembly must also be
replaced.
OPERATION
The multistage passenger airbag is deployed by electrical signals generated by the Occupant Restraint Controller
(ORC) through the passenger airbag squib 1 and squib 2 circuits to the two initiators in the airbag inflator. By using
two initiators, the airbag can be deployed at multiple levels of force. The force level is controlled by the ORC to suit
the monitored impact conditions by providing one of four delay intervals between the electrical signals provided to
the two initiators. The longer the delay between these signals, the less forcefully the airbag will deploy.
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 instru-
ment 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.
