Air Bag: Description and Operation
Side Curtain Air Bag - Description
DESCRIPTION
Vehicles equipped with the Side Impact Airbag System utilize two Curtain Airbags mounted in each respective side of the headliner, stretching from the
middle of the A-pillar at the instrument panel along the roof line to the C-pillar at the rear shelf panel. This system is designed to provide supplemental
restraint to driver or outboard passengers in the event of a side impact collision.
Side Curtain Air Bag - Operation
OPERATION
The Occupant Restraint Controller (ORC) controls the curtain airbags. For side impacts, the ORC senses the impact severity through two side impact
sensors on each side of the vehicle). If the ORC determines the impact is severe enough, it will send an electrical signal to inflate the appropriate curtain
airbag. The airbag will inflate, dropping down from the ceiling between the headliner and windows/pillars, to provide supplemental restraint to driver or
outboard passengers in the event of a side impact collision. Once a curtain airbag has been deployed, the complete curtain airbag, headliner, upper A, B,
and C-pillar trim panel, and all damaged parts must be replaced on the deployed side.
Driver Air Bag - Description
DESCRIPTION
The driver airbag protective trim cover is the most visible part of the driver airbag system. The driver airbag trim cover is held in place by a latch and
hook system (1). The driver airbag is mounted directly to the steering wheel by two bolts on either side of the airbag (3). Located under the airbag cover
are the folded airbag cushion, the igniter and two squib connectors (2), the inflator, and the airbag cushion supporting components. The driver airbag is a
multistage-type that is designed to deploy with less force than those used in some prior models. A radial deploying fabric airbag cushion with internal
tethers is used. The airbag inflator is a dual-initiator, non-azide, pyrotechnic-type unit. Two keyed and color-coded connector receptacles on the driver
airbag inflator connect the two inflator initiators to the vehicle electrical system through two yellow-jacketed, two-wire pigtail harnesses of the
clockspring.
The driver airbag cannot be repaired, and must be replaced if deployed or in any way damaged. The driver airbag trim cover may be disassembled from
