Air Bag: Description and Operation
Side Curtain Air Bag - Description
DESCRIPTION
Optional side curtain airbags are available for this vehicle when it is also equipped with dual front airbags. These airbags are passive, inflatable,
Supplemental Restraint System (SRS) components, and vehicles with this equipment can be readily identified by a molded identification trim button with
the SRS - AIRBAG logo located near the top of each upper B-pillar trim panel. This system is designed to reduce injuries to the vehicle occupants in the
event of a side impact collision or a vehicle rollover incident.
Vehicles equipped with side curtain airbags have two individually controlled curtain airbag units. These airbag units are concealed and mounted above
the headliner where they are each secured to one of the roof side rails. Each folded airbag cushion is contained within a fabric wrap (5) that extends
along the roof rail from the A-pillar at the front of the vehicle to the D-pillar at the rear of the vehicle. The airbag unit is initially secured during
installation with metal clips and plastic push-in fasteners to the roof rail.
A long tether (3) extends down the A-pillar from the front of the airbag cushion, where it is retained to the pillar with plastic push-in routing clips and it
is secured to the base of the A-pillar near the belt line with a screw and a rivet nut. A short tether (6) at the rear of the cushion is secured by a screw to a
U-nut located near the top of the D-pillar.
The hybrid-type inflator (1) for each airbag is secured to the roof rail at the front of the airbag unit between the A-pillar and the B-pillar, and is
connected to the airbag cushion by a long tubular manifold (2). The entire assembly is secured to U-nuts spaced along the inside of the roof rail with
screws; however, the mounting provisions between the right and left curtain airbag units is asymmetrical by design.
A two-wire pigtail harness (4) is routed from the rear of the airbag inflator and down the B-pillar, where it is retained by routing clips. The pigtail
harness is connected to a take out and connector of the body wire harness on the B-pillar, which connects the airbag unit to the Occupant Restraint
Controller (ORC).
