Side Curtain Air Bag - Description

DESCRIPTION





Side curtain air bags are standard equipment on this vehicle. These air bags 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 upper B-pillar trim. This system is designed to reduce injuries to the vehicle occupants in the event of a side impact collision.





Vehicles equipped with side curtain air bags have two individually controlled curtain airbag units (8). These airbag units are concealed and mounted above the headliner where they are each secured to one of the roof side rails (5). Each folded airbag cushion is contained within a fabric wrap and extruded plastic channels that extend along the roof rail from the A-pillar (6) at the front of the vehicle to the rearmost pillar of the vehicle. A long tether (7) extends down the A-pillar toward the belt line from the front of the airbag cushion, where it is retained to the inside of the pillar with plastic push-in fasteners.

The hybrid-type inflator (3) for each airbag is initially secured by a bracket with a T-tab at the front into a keyed slot in the roof rail above the B-pillar (standard cab) or above the rear door opening (quad or crew cab and mega cab), and is connected to the airbag cushion by a long tubular manifold (4). The airbag is then secured during installation with a single plastic push-in fastener to the roof rail. The entire assembly is then secured along the inside of the roof rail with screws.

The initiator of the airbag inflator is connected to the vehicle electrical system by a dedicated two-wire take out and connector of the body wire harness routed up the B-pillar (standard cab) or C-pillar (quad or crew cab and mega cab). A keyed and latched connector insulator (1) is connected directly to the connector receptacle of the initiator near the rear of the 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.
