PROBLEM TO BE SOLVED: To provide a head protection airbag which solves the problem that the develop of a resin material equipped with impact characteristics to endure airbag inflation is not easy, and that a material which highly satisfies a plurality of required performances needs to be developed because of changes in molding processability or damage resistance by addition of another modifier.SOLUTION: In a head protection airbag stored from the roof side part of a car body to the pillar part to spread by inflation, a gas introduction part is arranged on the top of an air bag body 20 and connected to an inner bag 24 with a length enough for the tip to reach the pillar parts 2, 3 from the roof side part 1, and the inner bag 24 is closed in areas corresponding to the pillar parts 2, 3. The air bag body 20 receives a gas supply at a position corresponding to the roof side part 1 to inflate downward of the roof side part 1 and makes the part corresponding to the pillar parts 2, 3 inflate downward of the pillar parts 2, 3 by the gas supplied at the position corresponding to the roof side part 1. |
