Abstract: Described are elastic tubular devices including an inner tube (23) made of an elastic and gas impermeable material; and a sheath (21) surrounding the inner tube and made of a woven cloth of flame resistant meta-aramid yarns, wherein the tubular device has a longitudinal extension of at least approximately 1.4 when inflated by a gas having a pressure of at least approximately 0.5 bar.

Abstract: The invention relates to a respiratory gas supply circuit for an aircraft carrying passengers, comprising a pressurized source of respiratory gas (R1, R2) and a supply line (2, 3), said circuit further comprising on said supply line a regulating device (12, 30) for controlling the supply in respiratory gas to said passengers, wherein said regulating device further comprises an electro-valve (12) controlled by a pulse width modulation signal provided by an electronic unit (20).

Abstract: A breathing mask (1) for aircraft crewmember or passenger comprises a rigid portion (3) to be fit against the face of an user, said rigid portion comprising elements to bring a breathable gas to the user. The breathing mask further comprises an extensible harness (4) having end portions (5) connected to said rigid portion and including an inflatable element (6) connected to a source (7) of pressurized gas through a manually operable valve which delivers the pressurized gas to the inflatable element for extending the harness when actuated, and which reduces the pressure in said inflatable element to retract the harness and to cause the rigid portion to engage the face of the user when released. The source of pressurized gas is an autonomous container (7) supported by the rigid portion and containing the pressurized gas.

Abstract: The invention relates to a respiratory gas supply circuit for an aircraft carrying passengers and/or crewmembers (1) in a cabin, including a source of breathable gas (R1, R2), at least one supply line (20) connected to said source, a first actuating device (60, 12) provided on said supply line to open at least partially or close the supply of breathable gas, a respiratory device (50) adapted to be worn on one passenger or crewmember's face, said respiratory device being connected to said supply line, and further including an ambient air inlet (40), said respiratory device providing to said one passenger or crewmember a respiratory gas to be inhaled corresponding to ambient air and/or breathable gas, wherein said ambient air inlet further includes a second actuating device (4, 11) to open at least partially or close said ambient air inlet; and, both said first and second actuating devices are operated so that at least one of said first and second actuating devices is closed at each instant of time.

Abstract: Systems for supplying emergency oxygen or other gases to persons are addressed. The systems may include pod assemblies mounted on fixed-position masts between or adjacent passenger seats or pop-up modules installed within upper portions of seat backs. The pod assemblies and pop-up modules additionally may include other passenger-service equipment. Also optionally included in the systems are modular central gas supplies and alternative oxygen mask designs for passengers.
