Abstract

Selon la présente invention, dans un airbag latéral, un airbag (10A) est plié sous forme de rouleau depuis une partie avant jusqu'à une partie arrière dans un habitacle et est fixé et logé au niveau d'une position prédéterminée. Ledit airbag (10A) s'étend et se gonfle sous forme de rideau le long d'une surface intérieure du côté de l'habitacle lorsqu'une collision ou similaire est détectée. Une partie d'encoche (15) est disposée à une position prédéterminée d'un bord sur l'airbag (10A). La partie d'encoche (15) constituant une limite, la forme de pliage de parties pliées (10d), (10e) qui sont disposées sur les bords d'extrémité de l'airbag plié (10A), est créée de manière à obtenir une forme approximative de Z et une forme approximative de V. Par conséquent, le sens de gonflage de l'airbag (10A) qui est gonflé par une expansion à une étape préalable des parties pliées (10d), (10e) peut être modifié, la partie d'encoche (15) constituant la limite.
