An inflatable device having a bladder (2) bounding a chamber (3) and a passage (4) for filling that chamber (3) is provided with a cover (6) covering a portion of the bladder (2) and with a shut-off structure (8) between the cover (6) and the bladder (2). The shut-off structure (8) has an operating member (9) extending along a first surface area (10) of the bladder (2) and a shut- off portion (11) having a second surface area (12) displaceable between a forward position at least partially shutting off the passage (4) and a retracted position clearing the passage (4). When, during inflation, a predetermined pressure has been achieved, the shut-off structure is compressed between the tensioned cover and the inflated bladder, which causes the shut- off portion to move into its forward position at least partially shutting off the passage (4).

Ce dispositif gonflable présente une poche (2) entourant une chambre (3) et un passage (4) destiné au remplissage de cette chambre (3) et il est pourvu d'un élément couvrant (6) recouvrant une portion de la poche (2) ainsi que d'une structure de fermeture (8) placée entre l'élément couvrant (6) et la poche (2). Cette structure de fermeture (8) présente un organe de fonctionnement (9) s'étendant le long d'une première zone superficielle (10) de la poche (2), ainsi qu'une portion de fermeture (11) présentant une seconde zone superficielle (12) pouvant se déplacer entre une position antérieure dans laquelle elle ferme au moins partiellement le passage (4) et une position rétractée dans laquelle elle libère le passage (4). Lorsque, durant le gonflage, on obtient une pression prédéterminée, la structure de fermeture est comprimée entre l'élément couvrant mis sous tension et la poche gonflée, ce qui provoque le déplacement de la portion de fermeture vers sa position antérieure, dans laquelle elle ferme au moins partiellement le passage (4).
