Air Bag: Description and Operation
Passenger Airbag
Description
DESCRIPTION
The passenger airbag is located behind the passenger airbag cover (3), between the glove box (5) and instrument panel top cover.
The passenger airbag includes a stamped steel housing within which the cushion and inflator are mounted and sealed. Two stamped metal brackets, one
on each end of the housing, enclose the cushion and inflator. The mounting scheme consists of two weld studs and a bracket with two tabs off the bottom
of the housing.
Following a passenger airbag deployment, the passenger airbag and the passenger airbag cover must be replaced. If inspection reveals that the passenger
airbag mounting points on the instrument panel structural duct have been cracked or damaged, the instrument panel assembly must also be replaced. The
passenger airbag cannot be repaired, and must be replaced if deployed or in any way damaged.
Operation
OPERATION
The hybrid-type inflator assembly includes a small canister of highly compressed argon gas. The inflator seals the hole in the airbag cushion so it can
discharge the gas it produces directly into the cushion when supplied with the proper electrical signal. Following an airbag deployment, the airbag
cushion quickly deflates by venting this gas through the porous fabric material used on each end panel of the airbag cushion.
The passenger airbag is secured with screws to the instrument panel structural duct beneath the instrument panel top pad and above the glove box
opening.
