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 ( 10 a ) 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 ( 10 a ) from being displaced forward.

First claim

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.
