Seat Air Bag - Description

DESCRIPTION





The seat airbags (also known as thorax airbags) are completely concealed beneath the seat back trim cover on the upper outboard sides of both front seat backs. These airbags are inserted into a sewn pouch on the inside of the trim cover, then secured to the seat back frame by nuts on two studs (3). One stud is located on the stamped metal airbag housing (2), while the second stud is located on the stamped metal airbag lower bracket (4).

The folded seat airbag cushions are contained within a retainer wrap (1) constructed of the same material as the airbag cushion. The retainer wrap completely encloses the airbag cushion and is engaged over the stud on the housing for retention. The airbag cushion is constructed of a coated nylon fabric.

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

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