    Abstract: PROBLEM TO BE SOLVED: To suitably constrain an occupant on a front passenger seat by an airbag even if the occupant is close to an instrument panel at the time of front collision of a vehicle. SOLUTION: When the airbag 12 supplied with gas expands and deploys to a side of the occupant on the front passenger seat, a first to-be-fractured part 21 and second to-be-fractured parts 22 in the instrument panel 16 are fractured to form an opening part 56 for expansion of the airbag 12. Expansion/deployment at a center area 12A of the airbag 12 is suppressed by a flap 14 (deployment control cloth), and an end part area 12B is expanded/deployed earlier than the center area 12A is. The first to-be-fractured part 21 extends to the vehicle width direction in an area corresponding to a general part 14A of the flap 14. The second to-be-fractured parts 22 are formed to diverge from both end parts 41 of the first to-be-fractured part 21 respectively to the vehicle front side and to the vehicle rear side. The second to-be-fractured parts 22 are easier to be fractured than the first to-be-fractured part 21 is. COPYRIGHT: (C)2010,JPO&INPIT
