1. An airbag apparatus to be applied to a vehicle, the airbag apparatus comprising:
a far-side airbag to be disposed on a center console side of a seat backrest of a front seat of the vehicle, the far-side airbag comprising a single cylindrical base fabric member, the far-side airbag having an annular outer periphery, the far-side airbag having, in an inner periphery:
a shoulder protection air chamber having a back shoulder air chamber, a side shoulder air chamber, and a front shoulder air chamber that are each to be expanded into a longitudinal cylindrical shape configured to protect a shoulder of an occupant in the vehicle;
a head protection air chamber to be expanded into a semicircular shape and configured to fall against the occupant seated in the front seat of the vehicle to protect a head portion of the occupant; and
a non-inflating unit disposed adjacent to the back shoulder air chamber; and
an expansion control processor configured to control expansion of the far-side airbag,
wherein the non-inflating unit comprises an inflator therein, the inflator being covered with a cylinder,
wherein the far-side airbag has a gas passage through which high-pressure gas is discharged from:
an upper discharge port of the cylinder and is fed into the head protection air chamber; and
a lower discharge port of the cylinder and is fed into the front shoulder air chamber,
wherein the high-pressure gas discharged from the lower discharge port and the high-pressure gas discharged from the upper discharge port merge with each other at a first aperture provided between the head protection air chamber and the shoulder protection air chamber, thereby creating a merged high-pressure gas,
wherein the merged high-pressure gas flows through the first aperture into the back shoulder air chamber to expand the back shoulder air chamber, and
wherein the merged high-pressure gas subsequently flows into the side shoulder air chamber through a second aperture to expand the side shoulder air chamber.
