An air bag device includes an air bag which is accommodated in a folded state along sides of a seat back and a seat cushion of a seat for an occupant. Upon side collision of a vehicle, the air bag is expanded by a gas generated by an inflator and deployed between an inner surface of a side of a vehicle compartment and an occupant. The air bag is disposed outside a lap belt of a seat belt device, and hence is deployed from the sides of the seat back and the seat cushion, so that a shock-absorbing effect can be effectively exhibited.
An inflatable airbag system for a vehicle seat assembly of a vehicle. The inflatable airbag system includes a cover member adapted for mounting to the vehicle seat assembly. The inflatable airbag system also includes an inflatable airbag adapted to inflate outward from the cover member and outward from the vehicle seat assembly to thereby act as a protective barrier between an occupant of the vehicle seat assembly and an interior surface of the vehicle.
