Pedestrian protection airbag device
First Claim
1. A pedestrian protection airbag device comprising:
- an airbag case that is disposed in front of a wiper, both the airbag case and the wiper being disposed under a hood, with a length direction of the airbag case extending along a vehicle width direction, a middle region of the airbag case, when viewed in a vertical cross-section that extends in a vehicle front-and-rear direction, has a cross-sectional height in a vehicle up-and-down direction that is smaller than a cross-sectional height in the vehicle up-and-down direction of a general portion of the airbag case located at outer ends of the middle region of the airbag case, the airbag case being arranged in contact with and along a lower face of a bulge portion formed in a hood inner panel comprised of the hood, the bulge portion bulges to a vehicle lower side thereof and extends along the vehicle width direction;
a pair of inflators that are respectively accommodated at each of outer ends in the vehicle width direction of the middle region of the airbag case; and
an airbag that is folded and accommodated in the airbag case, the airbag inflating and expanding, due to pressure of gas generated by the inflators, to a vehicle rearward side through a gap between a hood rear end portion and a windshield glass.

Abstract
A pedestrian protection airbag device includes an airbag case, a pair of inflators and an airbag. The airbag case is disposed at a lower face side of a hood rear end portion with a length direction thereof extending along a vehicle width direction. A vehicle width direction middle region of the airbag case, when viewed in a vertical cross-section extending in a vehicle front-and-rear direction, has a cross-sectional height in a vehicle up-and-down direction smaller than a cross-sectional height in the vehicle up-and-down direction of a general portion of the airbag case located at outer ends in the vehicle width direction of the middle region. The inflators are accommodated at both of vehicle width direction ends of the middle region. The airbag in the airbag case inflates from pressure of gas generated by the inflators, and deploys rearward through a gap between the hood rear end portion and a windshield.
