AIRBAG APPARATUS

An airbag apparatus includes a far-side airbag and an expansion control processor controlling expansion of the far-side airbag. The far-side airbag is a cylindrical base fabric member, has an annular outer periphery, and has a shoulder protection air chamber, a head protection air chamber, and a non-inflating unit in an inner periphery. The shoulder protection air chamber is expanded into a longitudinal cylindrical shape to protect a shoulder of an occupant seated in a vehicle front seat. The head protection air chamber is expanded into a semicircular shape and falls against the occupant to protect the occupant's head. The non-inflating unit is disposed adjacent to the back shoulder air chamber and includes an inflator covered with a cylinder. The far-side airbag has a gas passage through which high-pressure gas discharged from discharge ports of the cylinder are fed to the shoulder protection air chamber and the head protection air chamber.
