Description And Operation: Description
Side curtain airbags (also known as Side AirBag Inflatable Curtains/SABIC) are standard equipment for this vehicle on all models of this vehicle in North America except Mexico and export markets in which some models are not equipped with SABIC. These airbags are passive, inflatable Supplemental Restraint System (SRS) components. The side curtain airbag system is designed to reduce injuries to the vehicle occupants in the event of a side impact collision. Each side curtain airbag cushion provides coverage of the side glass adjacent to all seating positions on the same side of the vehicle as the monitored impact.
Each vehicle is equipped with two individually controlled side curtain airbag units (1). These side curtain 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 and several miniature plastic wrappers (3) that extend along the roof rail from the A-pillar at the front of the vehicle to the D-pillar. A tether (4) extends from the front and the rear of the side curtain airbag cushion. The end of each tether is secured to the A-pillar (front tether) or D-pillar (rear tether) sheet metal.
The inflator bracket and the plastic wrappers are secured with nuts to weld studs on the roof rail. The airbag inflator is connected to the vehicle electrical system through a dedicated take out and connector (2) of the body wire harness near the top of the C-pillar. The body wire harness connects the side curtain airbag unit to the Occupant Restraint Controller (ORC).
The side curtain airbag units 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 side curtain airbag unit, the headliner, the upper A, B, C and D-pillar trim, as well as all other visibly damaged components must be replaced.
