Embodiment Construction

[0065] figure 1 Depicted is a system 10 for delivering supplemental breathing gas (oxygen) to passengers on an aircraft. The system 10 is implemented in an aircraft, more precisely in the passenger cabin of the aircraft. The cabin of an aircraft is pressurized such that the cabin ambient air 2 is pressurized and contains a standard oxygen rate (about 21%). The system 10 is intended to top up in the event of depressurization due to a pressurization device failure or an uncontrolled leak between the cabin and the exterior and / or in the presence of toxic gases (smoke in particular) in the cabin ambient air 2 Breathing gas (oxygen) is delivered to passengers on board the aircraft. Typically, system 10 is placed over the heads of passengers and is configured to deliver supplemental breathing gas (oxygen) to a row of passengers.

[0066] figure 1 The system 10 shown in includes a box 70 (commonly referred to as a shedding box), a breathing source (oxygen source 14), at least one...

Abstract

A system (10) for delivering breathing gas to a passenger, the system comprising:-a mask (30) comprising a face portion (20) having a breathing lumen (34); -a tube (4B) configured to be supplied with a pressurized breathing gas; and-a gas pocket (40) disposed between the tube (4B) and the facial portion (20), a passage (35) connecting the gas pocket (40) to the breathing chamber (34) such that the system is configured to supply the breathing chamber (34) via the gas pocket (40), the gas pocket (40) comprising a front portion (40a) connected to the mask (30) and a rear portion (40b) connected to the front portion (40a), the front portion (40b) being connected to the rear portion (40b). The system has a stowed configuration in which the gas pocket (40) remains folded between the backing (50) and the face portion (20), and an expanded configuration in which the gas pocket (40) remains folded between the backing (50) and the face portion (20).

Description

technical field [0001] This invention relates to systems for delivering oxygen or other breathing gases to passengers on board an aircraft, and more particularly, but not necessarily exclusively, to techniques for storing and deploying the air storage bags of such systems. Background technique [0002] During the cruise portion of the flight, most commercial airliners operate at altitudes in excess of fourteen thousand feet. At these altitudes, there may not be enough oxygen in the ambient air to sustain human consciousness or life. Accordingly, the passenger cabin of an aircraft is often pressurized to an altitude equal to approximately eight thousand feet. At such "cabin altitudes" sufficient oxygen will generally be present in the ambient air to avoid hypoxia, and thereby maintain human consciousness and life. [0003] Thus, loss of cabin pressurization places passengers (and crew) at risk of experiencing hypoxia when the aircraft is flying above, for example, fourteen ...
