Abstract

Cette invention se rapporte à un coussin gonflable dans lequel, sans utiliser de coutures déchirables, un trou d'aération ouvert/fermé est fermé ou légèrement ouvert à l'étape initiale de gonflage du coussin gonflable et le trou d'aération ouvert/fermé est ouvert ou largement ouvert lorsque la génération de gaz en provenance d'un gonfleur est réduite ou arrêtée, et à un dispositif de coussin gonflable. Un sac interne (16) ayant un volume inférieur au coussin gonflable (10) est installé dans le coussin gonflable (10). Un corps de couvercle (60) pour couvrir le trou d'aération ouvert/fermé (20) et le sac interne (16) sont reliés l'un à l'autre par une longe (70). Lorsque la pression dans le sac interne (16) est supérieure à la pression dans le coussin gonflable (10) au début du gonflage du coussin gonflable (10), le sac interne (16) est tendu car il est complètement gonflé. Cela empêche la séparation du corps de couvercle (60) du trou d'aération ouvert/fermé (20) en coopération avec la longe (70). Lorsque la génération du gaz en provenance du gonfleur (36) diminue ou s'arrête, le sac interne (16) devient lâche et le couvercle (60) se sépare du trou (20) d'aération ouvert/fermé pour ouvrir le trou d'aération ouvert/fermé (20).
