The invention further relates to a breathing bag, with which a flow indicator is integrated into the connection piece.

In an illustrative embodiment, an integrated speaker-light unit includes a base unit adapted to be mounted to a fixture of an aircraft, a speaker unit disposed proximate the base unit, a horn element having a proximal end and a distal end, the proximal end positioned proximate the speaker unit and defining a first aperture, and the distal end defining a second aperture, where a greatest measurement of the second aperture is larger than a greatest measurement of the first aperture, an LED unit disposed at least partially in the horn element, and a housing element at least partially surrounding the horn element. The greatest measurement of the second aperture may be less than 4 inches. The base unit may be mounted to a passenger service unit such that the integrated speaker-light unit is presented as a passenger reading light.

Full hood respirator comprising a fluidtight flexible bag intended to be slipped over the head of a user, the flexible bag being provided with a transparent window and comprising, in its lower part, a rigid base element of annular overall shape intended to be positioned around the neck of the user, the base element comprising a tubular oxygen reservoir of pressurized oxygen provided with a calibrated outlet orifice opening into the internal volume of the flexible bag, characterized in that the base element comprises at least two rigid parts connected by an articulation, the two parts being movable relative to one another between a furled first position that prevents a head from entering the hood through the base element and an unfurled position of use that allows a head to enter the hood through the base element.

A position detector for a passenger service unit which can be installed in a passenger service channel. The position detector includes a sensor rail which has a multiplicity of sensors and is configured to be fitted in the longitudinal direction of the passenger service channel. The position detector also includes a position marker which is configured to be fastened to the passenger service unit and to trigger a sensor signal at one of the multiplicity of sensors. A passenger service channel having a position detector and a vehicle area having a passenger service channel are also described.

An emergency oxygen system for aircraft comprising: a breathing gas supply circuit to be connected upstream to a source of breathing gas and downstream to at least one mask, a flow control valve configured to adjust the flow of breathing gas supplied to the mask, an electronics board configured to control the flow control valve, a power source, a switching device interposed between the power source and the electronics board, the switching device comprising a switch configured to have a first state in which power from the power source is supplied to the electronics board and a second state in which the electronics board is not supplied with power from the power source.

An oxygen supply system includes a container housing having a container door, a latch controller coupled to a latch of the container door and configured to control the latch to releasably open the container door, a microcontroller coupled to the latch controller and configured to output a first latch deployment signal to the latch controller to cause the latch controller to open the latch, a pressure sensor coupled to the latch controller and configured to output a second latch deployment signal to the latch controller to cause the latch controller to open the latch, and an energy storage coupled to the microcontroller and the pressure sensor and configured to supply the microcontroller and the pressure sensor with electrical energy. The microcontroller includes built-in test equipment (BITE) configured to monitor and test the operability of one or more of the microcontroller, the latch controller, the pressure sensor and the energy storage.

A system for delivering breathing gas to passengers on-board an aircraft, comprising: a source of breathing gas, at least one face mask for passengers, a reservoir associated with each face mask, a delivery valve for each face mask, the delivery valve being disposed between the source of breathing gas and the reservoir, the reservoir being disposed between the delivery valve and the face mask, a sensor associated with each reservoir and configured to sense a filling of the reservoir, and a controller configured to control the delivery valve in a continuous supply mode to provide a continuous flow of breathing gas to the reservoir and to interrupt the continuous flow of breathing gas when the filing sensed by the sensor is a filling threshold.

A passenger service unit (PSU) for a transport vessel has a unitary chassis with a plurality of apertures extending therethrough. Each one of the apertures is independently sized to receive at least one of a plurality of different modules. Each one of the modules includes one or more PSU fixtures having components different from other ones of the plurality of modules. A representative vessel is a passenger aircraft. Representative modules include vent and passenger reading light module, speaker module, passenger oxygen supply module and display module.

An oxygen mask container assembly that includes a container that defines a container interior and includes a container opening, an oxygen mask assembly disposed in the container interior, a mask ejector in operative communication with the mask assembly, a cover assembly that is movable between a closed position where the cover assembly covers the container opening and an open position where the mask can be ejected through the container opening and from the container interior, and a latch assembly. The oxygen mask assembly includes a mask and a lanyard. The cover assembly includes a light assembly therein that is configured to shine light below the cover assembly. The latch assembly is configured to move the cover assembly between the closed position and the open position.

The invention relates to an overhead luggage compartment for aircraft, comprising: a tray for accommodating pieces of luggage, which tray can be pivoted about an axis of rotation between a closed position and an open position; and comprising a housing, which encloses the tray in the closed position and which has devices arranged thereon for fastening to a supporting structure of the aircraft and has a suspension device for a passenger service unit; and comprising a closure element for holding the tray in the closed position. The housing is formed by two frame parts arranged lateral to the tray, which frame parts are connected to each other by means of cross-braces, and the fastening devices and the suspension device for the passenger service unit and at least one stop element for limiting the open position of the tray are arranged on the frame parts.
