Air Bag, Seat: Description

GC0145819Courtesy of CHRYSLER GROUP, LLC

Seat AirBags (SAB) are standard equipment on this model. 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 (2). Both studs are installed on a stamped metal bracket located within the SAB case (1) and exit through the inboard side of the housing.

The folded SAB cushion is contained within and protected by the molded plastic clamshell-type SAB case. The cushion is constructed of a coated nylon fabric. The SAB housing also contains the SAB inflator and a high pressure cylinder filled with inert gas. The SAB inflator is a single-initiator, hybrid-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 (3). 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.
