Air Bag: Description and Operation
Side Curtain Airbag
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 on the headliner over the roof side rail (club cab) or near the top of each upper B-pillar trim panel (quad cab). This
system is designed to reduce injuries to the vehicle occupants in the event of a side impact collision.
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 (9)
that extends along the roof rail from the A-pillar at the front of the vehicle to the pillar at the rear of the vehicle. The channel is initially secured during
installation with two plastic push-in fasteners (8) to the roof rail.
A long tether (2) 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 (10)
and it is secured to the base of the A-pillar near the belt line with a metal clip (1). A short tether (6) is secured by a second metal clip to the header over
the glass at the back of the cab.
The hybrid-type inflator (4) for each airbag is secured to the roof rail at the front of the airbag unit above the front door opening, and is connected to the
airbag cushion by a long tubular manifold (5). The entire assembly is secured to six U-nuts spaced along the inside of the roof rail with six screws (7).
A two-wire takeout and connector of the body wire harness is connected directly to the connector receptacle of the initiator (3) near the front of the
airbag inflator. The body wire harness connects each curtain airbag unit to the Occupant Restraint Controller (ORC).
The side curtain airbag unit cannot be adjusted or repaired and must be replaced if deployed, ineffective, or in any way damaged. Once a side curtain
airbag has been deployed, the complete airbag unit, the headliner, the upper A, B, and C-pillar trim, and all other visibly damaged components must be
replaced.
