Driver Airbag: Description
The injection molded, thermoplastic driver airbag protective trim cover (2) is the most visible part of the driver airbag. The driver airbag is located in the center of the steering wheel (1), where it is secured with two screws to the two horizontal spokes of the four-spoke steering wheel armature. An injection molded, bright emblem with the Jeep® logo is applied to the center of the trim cover.
Concealed beneath the driver air bag trim cover are the horn switch, the folded airbag cushion, the airbag housing, the airbag inflator and the retainers that secure the inflator to the housing. The airbag cushion (1), housing (5), and inflator (4) are secured within an integral receptacle molded into the back of the trim cover. The four vertical walls of this receptacle have numerous small windows with blocking tabs that are engaged by numerous hook formations around the perimeter of the airbag housing. Each hook is inserted through one of the windows and the blocking tab in each window keeps the hook properly engaged with the trim cover, locking the trim cover securely into place on the airbag housing.
The resistive membrane-type horn switch is secured within a plastic tray that is inserted in a pocket or pouch sewn onto the airbag cushion retainer strap, between the trim cover and the folded airbag cushion. The horn switch ground and feed pigtail wires have a molded plastic connector insulator (3) that is secured by an integral retainer in a locator hole near the upper left corner of the airbag housing and is connected to the vehicle electrical system through a dedicated take out and connector of the steering wheel wire harness.
The airbag used in this vehicle is a multistage-type that complies with revised federal airbag standards to deploy with less force than those used in some prior vehicles. A radial deploying fabric airbag cushion with internal tethers is used. The airbag inflator is a dual-initiator, non-azide, pyrotechnic-type unit with four mounting studs and is secured to the stamped metal airbag housing using four flanged hex nuts. Two keyed and color-coded connector receptacles on the driver airbag inflator connect the two inflator initiators to the vehicle electrical system through two yellow-jacketed, two-wire pigtail harnesses of the clockspring.
The driver airbag cannot be repaired, and must be replaced if deployed, ineffective, or in any way damaged. The driver airbag trim cover, the horn switch and the cruise control switches may be disassembled from the driver airbag unit, and are available for individual service replacement.
