Described are concepts that generally relate to a personal positive pressure purified air environment for airplane travel. Simply put, certain embodiments of the present invention are directed to connecting a tube to an airplane air vent at one end and a clear plastic hood, mask, or helmet at the other end. The clear plastic hood, mask, or helmet all have an exit path for the air to flow out. In relation to the clear plastic hood embodiment, it is envisioned that the clear plastic hood can simply drape over person's head with the hood's opening at or above a person shoulder while positive pressure from the filtered air constantly flows out from the hood's opening.

A device for keeping ready passenger oxygen masks is disclosed. In embodiments, the device comprises an oxygen connection and a module container which can be fastened onto or installed in a passenger service unit (PSU) and includes compartments for receiving passenger oxygen masks, said passenger oxygen masks being connectable to the oxygen connection and being arranged ready for use. The module container comprises a release opening with an opening edge, and a cover which closes the release opening. The cover is releasably fastened to the opening edge and comprises a pull flag for removing the cover from the opening edge, wherein the cover and/or the pull flag is connected to an activation unit for activating an oxygen flow from the oxygen connection to the respective passenger oxygen mask.

A device for regulating breathing gas delivered to a user, comprising a gas circuit comprising a main line having at least an upstream end intended to be connected to at least one gas source and a downstream end intended to be connected to at least one user station such as a mask, the main line comprising at least one electromechanical control valve configured to regulate the gas pressure between the upstream and the downstream, the circuit comprising a secondary line comprising an upstream end intended to be connected to at least one gas source and a downstream end intended to be connected to the same user station(s), the secondary line comprising at least one auxiliary member for regulating the gas flow, the device comprising a switching system configured to control the flow of gas between the upstream and the downstream of the circuit via the main line or via the secondary line, characterized in that the auxiliary member for regulating the secondary line is a pneumatic pressure regulator.

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 illuminated aircraft passenger cabin gasper comprises an air outlet for outputting a flow of air into an aircraft passenger cabin and an air guide, movably arranged within the air outlet for adjusting the flow of air that includes a light guide. The gasper also includes at least one light source, arranged adjacent to the light guide for coupling light into the light guide. The light guide has a light output surface for coupling light out of the light guide into the aircraft passenger cabin.

The inflatable harness assembly for an aircraft oxygen crew mask includes one or more inflatable tubes having an outer layer of fabric material with an airtight coating for inflating the inflatable harness assembly. The inflatable tubes include an inner core of resilient, elastic material fixedly connected between first and second ends of the inflatable tubes that biases the inflatable tubes to shorten when the tubes are deflated. Inflation of the tubes them to expand the outer layer of material radially outwardly and lengthen axially, to allow the harness assembly to be placed over the user's head. Deflation of the tubes causes the aircraft inflatable harness assembly to grip the user's head with a desired head tension.

A system for the emergency oxygen supply of passengers in an aircraft includes at least one primary oxygen mask and at least one secondary oxygen mask arranged in the aircraft in a compartment above a seat, and a retaining receptacle arranged in the compartment. The at least one primary oxygen mask and at least one secondary oxygen mask are each connected to an oxygen source by way of a tube. The at least one primary oxygen mask drops out of the compartment before the at least one secondary oxygen mask when a flap of the compartment opens. The at least one secondary oxygen mask is arranged in the at least one retaining receptacle. The retaining receptacle is connected to the compartment by a first connector and to an activation device of the oxygen source by a second connector. The at least one primary oxygen mask can activate the oxygen source.

A mask stowage container is provided having a door panel coupled to a box via a securement mechanism, the securement mechanism having a striker having a neck and a protrusion, the striker mounted to the door panel, a holder, the holder including a first retainer and a second retainer, the striker configured to be laterally retained between the first retainer and the second retainer.

An aircraft includes a fuselage having a cabin. The aircraft also includes a cabin pressure sensor configured to detect cabin pressure level of the cabin. The aircraft further includes a controller configured to determine a pressure threshold as a function of a pressure altitude of a destination airport of the aircraft. The controller is also configured to activate a flight safety system based on the cabin pressure level satisfying the pressure threshold.

A device for provision of oxygen masks has a container, which can be closed by a cover, for accommodating one or more oxygen masks, at least one extendable arm having an outer end, and a driving device. The outer end is coupled to at least one oxygen mask. The arm is designed to adopt a storage position, wherein the arm is arranged completely within the container, and an extended position, wherein the outer end is extended out of the container and the arm holds the at least one oxygen mask coupled thereto laterally at a distance from the container. For extension, the driving device is coupled to the arm. The arm has an end piece, on which a wound-up hose can be releasably fixed. A fixing device is formed on the end piece in such a way as to release the wound-up hose when the extended position is reached.
