Seat Air Bag - Description

DESCRIPTION





Seat AirBags (SAB) (also known as pelvic and thoracic airbags) are standard equipment in all markets except Mexico. Vehicles with this equipment can be readily identified by a sewn tag with the SRS - AIRBAG logo located on the outboard side of the front seat back trim cover. These airbags are completely concealed beneath the seat back trim cover on the upper outboard sides of both front seat backs. Each SAB is inserted into a sewn pouch called an intensifier on the inside of the trim cover, then secured to the seat back frame by nuts on two studs (1). Both studs are installed on a stamped metal bracket. The stud on one end of the bracket exits through the SAB housing (2), while the second stud is located on the opposite end of the bracket that extends from the lower end of the housing.

The folded SAB cushion is contained within and protected by a molded plastic cover (3) secured to the outer edges of the housing. The SAB cushion is constructed of a coated nylon fabric.

The SAB housing contains the airbag inflator and a heat shield. The SAB inflator is a single-initiator, pyrotechnic-type unit that is secured to and sealed within the SAB housing. The SAB is connected to the vehicle electrical system through a dedicated jumper wire harness with a connector insulator that connects directly to the inflator initiator (4). The connector insulators are uniquely keyed and color-coded to ensure they can only be connected to the initiator.

The SAB cannot be repaired, and must be replaced if deployed, ineffective, or in any way damaged. If the SAB is deployed, the seat back frame, the seat back foam cushion, the seat back trim cover and the SAB jumper wire harness must also be replaced.
