The invention concerns an apparatus for producing a rapid air pressure equalisation between regions of an aircraft fuselage which are separated from each other by an aircraft fuselage structure and which have an air pressure difference relative to each other, in an aircraft, in particular a passenger aircraft, comprising at least one through-flow opening in the aircraft fuselage structure, a decompression flap (62) which at least partially closes the through-flow opening, and an unlocking mechanism which when a critical air pressure difference is exceeded unlocks the decompression flap (62) from its closed position so that the decompression flap (62) can be moved into an open position in which the through-flow opening is substantially opened. In accordance with the invention the decompression flap (62) comprises a plurality of portions which are hingedly connected together.

Dispositif servant à égaliser rapidement la pression d~air entre des régions du fuselage d~un aéronef, notamment d~un avion de ligne, séparées par une structure de fuselage d~aéronef et entre lesquelles existe une différence de pression d~air. Le dispositif comprend au moins une ouverture de passage d~écoulement dans la structure de fuselage d~aéronef, un volet de décompression (62) qui recouvre au moins partiellement l~ouverture de passage d~écoulement, et un mécanisme de déblocage qui, quand une différence de pression d~air critique est dépassée, débloque le volet de décompression (62) de sa position fermée de façon à le placer dans une position ouverte dans laquelle l~ouverture de passage d~écoulement est sensiblement découverte. Conformément à l~invention, le volet de décompression (62) comprend une pluralité de parties accouplées de manière articulée.
