Abstract

An airbag apparatus includes a first airbag (10) that deploys rearward from a position in front of an occupant (D) upon an oblique collision and a second airbag (20) that deploys so as to cover a cabin side wall upon an oblique collision. The second airbag (20) includes a wraparound portion (23) which deploys so as to protrude towards the inside of the cabin at a position further on the front side from an outer edge portion (10a) that is a portion, opposing the cabin side wall, of a peripheral edge of the deployed first airbag (10) to restrict the outer edge portion (10a) from being displaced forward.

Claims

1. An airbag apparatus for protecting an occupant upon an oblique collision of a vehicle, the airbag apparatus comprising:

a first airbag which is provided in front of the occupant and which deploys rearward upon the oblique collision; and

a second airbag which is provided on a lateral side of the occupant and which deploys so as to cover a cabin side wall upon the oblique collision, wherein

the second airbag includes a wraparound portion which deploys so as to protrude towards an inside of the cabin at a position further on a front side from an outer edge portion that is a portion, opposing the cabin side wall, of a peripheral edge of the deployed first airbag to restrict the outer edge portion from being displaced forward.

2. The airbag apparatus according to claim 1, wherein

the second airbag includes a front area portion that deploys to the front side of the outer edge portion of the first airbag and a rear area portion that deploys to a rear side of the outer edge portion of the first airbag, and at least a portion of the front area portion functions as the wraparound portion.

3. The airbag apparatus according to claim 2, wherein

the second airbag includes a recessed portion that is recessed towards the cabin side wall at a boundary position between the front area portion and the rear area portion.

4. A vehicle equipped with:

the airbag apparatus according to claims 1; and

a steering wheel provided in front of a driver'"'"'s seat, wherein

a first airbag deploys rearward from the steering wheel,

the steering wheel is supported so as to be movable forward in accordance with a load applied to the steering wheel upon an oblique collision, and

a wraparound portion deploys to a position where the wraparound portion comes into contact with the first airbag in a state where the steering wheel has moved forward.
