The emergency oxygen system is separate and distinct from the plurality of PSUs. A method includes providing a plurality of passenger service units (PSUs) within an internal cabin of a vehicle, and providing an emergency oxygen system within the internal cabin, wherein the emergency oxygen system is separate and distinct from the plurality of PSUs.

A supplemental oxygen assembly for a vehicle can include a container and a flow assembly attached to and/or configured to be contained within the container in a stowed position and to extend from the container in a deployed position. The flow assembly can be configured to be connected to an oxygen supply to supply oxygen to a person in the deployed position. The supplemental oxygen assembly can include an extension device connected to the flow assembly. The extension device can be configured to extend or allow extension of the flow assembly toward an aisle of the vehicle to aid the flow assembly in being reached from or moveable toward an aisle of the vehicle by a person in the aisle.

A passenger service unit, a passenger seating area, and a vehicle having a passenger service unit are provided, wherein the passenger service unit comprises a carrier element that can be extended in a longitudinal direction and a covering. The covering covers at least a section of the carrier element. At least one electrical and/or electronic element is integrated in the covering.

An aircraft mask monitoring system is provided, which includes a plurality of masks respectively corresponding to a plurality of seats in an aircraft. The masks are configured to deliver oxygen. Each mask includes at least one of a plurality of sensors, and each sensor is configured to detect an operational parameter of the respective mask as sensor data. The system further includes one or more processors configured to communicate with the sensors via a wired or wireless connection, receive the sensor data from the sensors, store the sensor data in an associated storage device, and process the sensor data using anomaly detection logic to generate a sensor data report. The sensor data report includes an anomaly state of at least one mask. The one or more processors are further configured to output the sensor data report for display on a client computing device.

An aircraft is capable of passing from the aerial domain to the spatial domain and method for automatically adapting the configuration of same. An additional breathable gas supply is provided to be activated only during a flight phase during which aerobic propulsion is interrupted, and is capable of supplying the control system of the manned cabin environment instead of the system associated with the aerobic propulsion means.

An oxygen supply system providing an adequate oxygen supply mode in an aircraft. A preventive oxygen supply system includes an oxygen source, a preventive oxygen dispensing unit connectable to the oxygen source, a cabin altitude detection device, and a preventive oxygen control device provide at least the following modes: a pre-wear mode providing no oxygen of the oxygen source to the preventive oxygen dispensing unit but normal cabin air; a pre-oxygenation mode providing a predetermined rate of oxygen of the oxygen source to the preventive oxygen dispensing unit sufficient for generating a pre-oxygenation condition of the user; and a decompression mode providing high concentrated oxygen of the oxygen source to the preventive oxygen dispensing unit sufficient for ensuring a minimum oxygenation of the user. The preventive oxygen control device automatically switches to the decompression mode in case a predetermined cabin altitude threshold is detected by the cabin altitude detection device.

The invention relates to an emergency oxygen device for passenger of an aircraft, including a chemical oxygen generator including a chemical oxygen source and an activation unit for initiating a chemical reaction of the chemical oxygen source producing oxygen, at least two oxygen masks each connected with the chemical oxygen generator for receiving an oxygen fluid flow from the chemical oxygen generator after the activation unit has initiated the chemical reaction, and a mechanical activation assembly for activating the activation unit. The activation unit is activated by a mechanical force exerted onto an activation element of the activation unit and the mechanical activation assembly includes for each of the at least two oxygen masks a first mechanical connection from the activation element to a fixation element releasably mounted to the emergency oxygen device and a second mechanical connection from the fixation element to the oxygen mask.

An aircraft gas transport system including a high pressure gas supply line having a supply valve, and an equilibrium gas line joined at junctions with the high pressure gas supply line upstream and downstream from the supply valve, and in flow communication with the high pressure gas supply line, the equilibrium gas line having an equilibrium valve and a flow restrictor, the equilibrium valve having an exit orifice and the flow restrictor being offset from the exit orifice of the equilibrium valve.

Portable breathing equipment and related methods are disclosed. An example portable breathing equipment (PBE) includes a housing defining a cavity, a cover movably coupled to the housing, and a smoke hood provided in a wrapper and positioned in the cavity. A first portion of the wrapper couples to the housing and a second portion of the wrapper couples to the cover. At least one of the cover or the housing to cause the wrapper to tear to provide an access opening to allow access to the smoke hood when the cover moves from a closed position at which the cover seals the cavity of the housing and an open position at which the cover enables access to the cavity of the housing.

An aircraft passenger service unit, which is configured for being installed in a passenger cabin of an aircraft, includes a seat detection sensor for determining a position and/or an orientation of at least one passenger seat, which is located in the vicinity of, in particular below, the aircraft passenger service unit.
