Abstract

Un dispositif de protection d'occupant (10a) destiné à protéger un occupant se trouvant dans le véhicule grâce au gonflage d'un coussin gonflable de protection du type rideau (100). Une bride d'attache (102) servant à relier le coussin gonflable de protection du type rideau (100) et la carrosserie de véhicule comporte un prétendeur (110) destiné à réduire le jeu entre le coussin gonflable de protection du type rideau (100) et la carrosserie de véhicule. Même s'il y a du jeu entre le coussin gonflable de protection du type rideau (100) et la carrosserie de véhicule en raison de la déformation de la carrosserie de véhicule qui survient lors d'une collision, le prétendeur (110) réduit le jeu entre le coussin gonflable de protection du type rideau (100) et la carrosserie de véhicule, et en conséquence, l'occupant est plus efficacement protégé.
