Abstract

Un dispositif de protection (14) d'occupant comprend un panneau avant (74) comportant une partie présentée vers l'occupant à l'état gonflé. Un évent (80, 80') pour libérer le fluide de gonflage a des états actionné et non. Une attache (112, 112') comporte un premier segment raccordé à l'évent et au panneau avant et un second segment (119) raccordé au panneau et à une partie arrière (38) du dispositif. Une couture de déchirure relie des parties du second segment de l'attache pour former une partie lâche de l'attache. La couture reste intacte de manière que le premier segment (118) soit lâche et que l'évent soit non actionné en réaction au déploiement initial du dispositif en dessous d'un degré prédéfini. La poursuite du déploiement amène la couture de déchirage à se rompre et à libérer la partie lâche, permettant au premier segment (118) du lien de l'attache de se tendre et d'agir sur l'évent vers l'état actionné.
