Abstract

L'objectif de la présente invention consiste en un dispositif de protection d'occupant pouvant protéger de façon appropriée l'occupant lors d'une collision à faible chevauchement. Un corps de coussin de sécurité gonflable en rideau (7) est suspendu à un montant avant (11) et à un panneau de toit (13). Le corps de coussin de sécurité gonflable en rideau (7) comprend : une première chambre (71) et une deuxième chambre (72) qui se détendent dans l'espace entre une fenêtre latérale (9), un montant central (10) et la tête (C) du conducteur ; et une troisième chambre (73) qui se détend dans l'espace entre la fenêtre latérale (9), le montant avant (11), un tableau de bord (12) et la tête (C) du conducteur. Lorsqu'une collision à faible chevauchement se produit, la troisième chambre détendue (73) reçoit une force de réaction provenant du tableau de bord (12), et reçoit ainsi la tête (C) du conducteur qui se déplace vers le montant avant (11).
