SIDE CURTAIN AIRBAG
Optional side curtain airbags are available for this model 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 on the headliner above each B-pillar. This system is designed to reduce injuries to the vehicle occupants in the
event of a side impact collision.
Fig. 46 Side Curtain Airbag
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 long extruded plastic channel
that extends along the roof rail from the A-pillar at the front of the vehicle to just behind the C-pillar at the rear of the vehicle. One tether extends
down the A-pillar from the front of the airbag cushion, and a second tether extends to the roof rail above the D-pillar. The ends of these tethers are
secured to slots in the sheet metal with metal hooks retained by plastic anchor clips.
The hybrid-type inflator for each airbag is secured to the roof rail at the rear of the airbag unit between the C-pillar and the D-pillar, and is connected
to the airbag cushion by a long tubular manifold. The inflator bracket and the extruded airbag cushion channel are secured with both plastic push-in
fasteners and screws to the roof rail. A short pigtail wire and connector connect the airbag inflator to a dedicated take out and connector of the body
wire harness near the top of the D-pillar.
