Side Curtain Air Bag - Description

DESCRIPTION





Side AirBag Inflatable Curtains (SABIC) (1) are standard factory-installed equipment for this vehicle. These airbags are passive, inflatable, Supplemental Restraint System (SRS) components. The SABIC system is designed to reduce injuries to the vehicle occupants in the event of a side impact collision. Each SABIC cushion provides full coverage of the side glass on the same side of the vehicle as the monitored impact.

Each vehicle is equipped with two individually controlled SABIC units. These SABIC 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 and several miniature plastic wrappers that extend along the roof rail from the A-pillar at the front of the vehicle to the C-pillar at the rear of the vehicle. A tether extends down the A-pillar from the front of the SABIC cushion, while a shorter tether extends back to over the C-pillar. The end of each tether (3) is secured to the sheet metal with a threaded fastener.

The hybrid-type inflator (2) for each SABIC is secured to the roof rail above the B-pillar and the rear window opening, and is connected to the airbag cushion by a long tubular manifold. The inflator bracket and the plastic wrappers are secured with both plastic push-in fasteners and screws to the roof rail. The inflator is initially hung from the roof rail by stamped metal hooks, then with screws. Color-coded labeling and tape on the SABIC unit identify the right side (red) from the left side (blue). In addition, a black line imprinted on the inboard side of the folded cushion is only visible if the cushion is twisted during installation.

The airbag inflator is connected to the vehicle electrical system through a dedicated take out and connector of the body wire harness near the top of the B-pillar. The body wire harness connects the SABIC unit to the Occupant Restraint Controller (ORC).

The SABIC units cannot be adjusted or repaired and must be replaced if deployed, ineffective, or in any way damaged. Once a SABIC has been deployed, the complete SABIC unit, the headliner, the upper A, B, and C-pillar trim as well as all other visibly damaged components must be replaced.
