The air bag includes a bag body, a mouth portion for introducing gas supplied from an inflator into the bag body, and a fixture portion for fixing the air bag to a case. The mouth portion is disposed in a central portion of the case. A vehicle front side portion of the bag body located on the front side of the vehicle relative to the mouth portion and a vehicle rear side portion of the bag body located on the rear side of the vehicle relative to the mouth portion are folded to be accommodated between the mouth portion and front and rear inner faces of the case respectively. Upon activation of the inflator, a passenger facing portion of the bag body that faces the passenger in an ultimate deployment state of the air bag is first deployed to a predetermined extent. Thereafter, due to application of tension forces acting in such a direction as to deploy the air bag, the other portions of the bag body that are in their folded states are deployed toward the vehicle front and rear sides respectively.

[ What is claimed is:] [1.]1. An air bag apparatus for protecting, a passenger, comprising:an air bag disposed in a vehicle compartment on a passenger side of an instrument panel;an inflator supplying gas to the air bag for causing it to deploy; anda case disposed on a vehicle front side of the instrument panel so as to accommodate the air bag,wherein the air bag is folded such that when the air bag is deployed due to activation of the inflator, a passenger facing portion of the air bag that faces a passenger when the air bags is fully deployed, deploys earlier than other portions of the air bag,wherein the air bag is folded such that the portions of the air bag other than the passenger facing portion are deployed due to application of tension forces acting substantially in such a direction as to deploy the air bag,wherein upper and lower portions of the air bag are pushed against front and rear inner faces, respectively, of the case during deployment,wherein the air bag includes a bag body that is deployed due to activation of the inflator, a mouth portion for introducing gas supplied from the inflator into the bag body, and a fixture portion for fixing the air bag to the case, the fixture portion being wound around the inflator,wherein the mouth portion is disposed in a central portion of the case and substantially parallel with front and rear inner faces of the case,wherein the upper portion of the bag body located on a vehicle front side of the case relative to the mouth portion and the lower portion of the bag body located on a vehicle rear side of the case relative to the mouth portion are folded to be accommodated between the mouth portion and the front and the rear inner faces of the case, respectively, the upper portion and the lower portion being on opposite sides of the mouth portion, andwherein, regarding the upper portion of the bag body and the lower portion of the bag body, at least the lower portion of the bag body is folded in a bellows and roll-bent such that an end thereof is initially bent downward and drawn toward the mouth portion.
