Abstract

The invention provides a side curtain airbag which can be simply arranged while an airbag body is simply folded so as to enable the airbag body to be stable, improve protection performance for passagers and ensure self shock absorption performance of an internal decoration material. A side curtain airbag (10) includes an airbag body (11) and a plurality of airbag fixation portions (12). The airbag body is divided into a plurality of cells (15) 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.

Description

technical field [0001] The present invention relates to side curtain airbags. Background technique [0002] In the past, a side curtain airbag is known. When an impact input occurs during a side collision or a rollover of the vehicle, the airbag body is deployed in a curtain-like manner between the side part of the vehicle body and the occupant to protect a wide area. crew. [0003] The above-mentioned side curtain airbag is accommodated between a vehicle body pillar and a garnish (interior material). Specifically, the garnish is attached so as to cover the body pillars, and the airbag bag is accommodated in a folded state between the body pillars and the garnish. [0004] In addition, when there is an impact input, high-pressure gas is blown from the inflator, thereby inflating the airbag body and moving while pushing the garnish toward the interior of the vehicle by the inflation pressure. Accordingly, the airbag body is deployed in the vehicle interior in a curtain-lik...
