Side curtain airbag
First Claim
1. A side curtain airbag fixed to the interior of a vehicle using a plurality of vehicle body side fixation portions provided in a vehicle body frame member along a side opening of a vehicle body, and stored between the vehicle body frame member and an interior decoration member, the side curtain airbag comprising:
- an airbag body divided into a plurality of cells that are inflated by gas flowing into them, the airbag body deploying toward the interior of the vehicle while pushing the interior decoration member to open; and
a plurality of airbag fixation portions provided along the upper periphery of the airbag body and attached to the plurality of vehicle body side fixation portions,wherein in a state before attachment, of the plurality of airbag fixation portions, an upper front airbag fixation portion is located above an upper front vehicle body side fixation portion of the plurality of vehicle body side fixation portions, the upper front vehicle body side fixation portion corresponding to the upper front airbag fixation portion, and the upper front airbag fixation portion is located at substantially the same level as the other airbag fixation portions,of the plurality of cells, an upper front cell is formed so as to bulge close to the upper front airbag fixation portion, andwherein the upper front cell is formed such that the internal volume increases as approaching the upper front airbag fixation portion such that, when the airbag body is deployed, an inflated portion with the increased volume of the upper front cell pushes the interior decoration member from the outside thereof toward the vehicle body frame member.

Abstract
A side curtain airbag includes an airbag body and a plurality of airbag fixation portions. The airbag body is divided into a plurality of cells that are inflated by gas flowing into them. The plurality of airbag fixation portions are provided along the upper periphery of the airbag body and attached to a plurality of vehicle body side fixation portions. In a state before attachment, of the plurality of airbag fixation portions, an upper front airbag fixation portion is located above the vehicle body side fixation portion corresponding to the airbag fixation portion, and at substantially the same level as the other airbag fixation portions. Of the plurality of cells, an upper front cell is formed so as to bulge close to the upper front airbag fixation portion.
