## Abstract

An airbag device includes an airbag stored in a storage part provided in front of an occupant seated on a seat, wherein: the airbag has an occupant protecting section configured to protect the occupant on a rear surface at the time of completion of inflation; the occupant protecting section includes: an upper half body restraining surface configured to receive the upper half body of the occupant; and a head receiving section formed in a left region and a right region of a center in a left-right direction of the occupant protecting section to protrude rearward from the upper half body restraining surface, in a region above the upper half body restraining surface; and the head receiving section is configured so that a part between a left restraining surface and a right restraining surface upon completion of inflation is continued from the upper half body restraining surface.

## Claims

### Claim 1

An airbag device comprising
an airbag stored in a storage part provided in front of an occupant seated on a seat, the airbag configured to deploy and inflate to protrude toward a rear side of a vehicle by flowing of an inflation gas therein, to protect the occupant, wherein:
the airbag has an occupant protecting section configured to protect the occupant on a rear surface at the time of completion of inflation;
the occupant protecting section includes:
an upper half body restraining surface, disposed in front of the occupant at the time of completion of inflation, configured to receive the upper half body of the occupant; and
a head receiving section formed in a left region and a right region of a center in a left-right direction of the occupant protecting section to protrude rearward from the upper half body restraining surface, in a region above the upper half body restraining surface, the head receiving section having a left restraining surface and a right restraining surface configured to receive a side surface of a head; and
the head receiving section is configured so that a part between the left restraining surface and the right restraining surface upon completion of inflation is continued from the upper half body restraining surface.

### Claim 2 (depends on 1)

The airbag device according to claim 1, wherein:
the airbag includes:
an airbag main body in which a lower side of the rear surface upon completion of inflation is set as the upper half body restraining surface; and
the head receiving section formed to partially protrude from an upper side on the rear surface of the airbag main body upon completion of inflation;
the head receiving section includes a left restraining section having the left restraining surface, and a right restraining section having the right restraining surface; and
the left restraining section and the right restraining section are arranged such that base portions thereof upon completion of inflation are positioned on the center side in the left-right direction relative to a left edge and a right edge on the rear surface of the airbag main body and protrude rearward from the upper half body restraining surface, in a state in which the airbag upon completion of inflation is viewed from above.

### Claim 3 (depends on 2)

The airbag device according to claim 2, wherein
the left restraining surface and the right restraining surface are inclined with respect to a front-rear direction so as to be expanded toward the front end side when the inflation of the airbag is completed.

### Claim 4 (depends on 3)

The airbag device according to claim 3, wherein
the left restraining surface and the right restraining surface are configured such that the base portions are brought into contact with each other when the inflation of the airbag is completed.

### Claim 5 (depends on 1)

The airbag device according to according to claim 1, wherein
the airbag is folded and stored in a storage part provided in an instrument panel disposed in front of an occupant seated on a passenger seat.

### Claim 6 (depends on 1)

The airbag device according to claim 1, wherein
the airbag is folded and stored in a storage part provided in a steering wheel in front of a driver seated on a driver's seat.
