There are three main types of SABs: chest (torso) SABs, head SABs, and head/chest combination (combo) SABs.
- Chest (torso) SABs are mounted in the side of the seat back or in the door and are designed to help protect an adult's chest in a serious side-impact crash.
- Head SABs are usually mounted in the roof rail above the side windows and are designed to help protect an adult's head in a side-impact crash. There are two types of head SABs: curtain SABs and tubular SABs. Curtain SABs can provide protection to both front and rear occupants in a side-impact crash; some may also stay inflated longer to provide protection from ejection if your vehicle rolls over after being struck on the side. Some new convertibles include head SABs that deploy upwards from the window sill.
- Head/chest combination ("combo") SABs are usually mounted in the side of the seat and are typically larger than chest (torso) SABs. Combo SABs are designed to help protect both the head and chest of an adult.
Consult your owner's manual or vehicle manufacturer for specific information on your vehicle's side air bag system.
