An emergency vision device includes an enclosed housing having a first end and a second end; first and second clear members disposed at the first and second ends, respectively; the housing including a plurality of wall panels joined side-to-side, the wall panels being foldable; and a loop of spring wire is operably associated with each of at least two of the wall panels.

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.

A respiratory equipment for an aircraft, a pilot or first officer of the aircraft forming a user of the respiratory equipment, the respiratory equipment comprising a head armature, configured to be worn on the user's head, a respiratory mask configured to be applied, in a use position around the mouth and nose of a user, an inflatable harness configured to be coupled to a pressurized gas source, an inflation of the inflatable harness causing an extension of the inflatable harness such that the respiratory mask can be brought opposite the mouth and nose of a user, and a purge of the inflatable harness causing a constrained application of the inflatable harness against the mouth and nose of a user, wherein the head armature comprises at least an occipital member, and a front cradle for receiving and lodging the respiratory mask in a waiting position, wherein the inflatable harness is fixed to the occipital member and the inflatable harness is coupled to the respiratory mask.

The invention relates to an oxygen mask for supplying oxygen to a person, which can be modified for use on differently sized faces. The oxygen mask has a holding frame, which has a first cross-brace and a second cross-brace, a substantially gas-impermeable material arranged on the holding frame and which can be stretched between the first cross-brace and the second cross-brace, a headband connected to the holding frame, an exhalation valve arranged on the material and penetrating the material, and an oxygen supply line for providing oxygen to an inside of the oxygen mask, wherein the first cross-brace and the second cross-brace are arranged in two lateral holders, which are opposite each other, wherein at least the first cross-brace is flexible and wherein the distance of the lateral holders to each other is adjustable at least between a first and a second distance.

A device for the provision of oxygen masks has a closeable container for oxygen masks, an extendable arm having links coupled in articulated fashion and having an outer end, and a driving device. The outer end is coupled to at least one oxygen mask. The arm adopts a storage position in which the arm is arranged completely within the container, and an extended position in which the outer end is moved out of the container and in which the arm holds the oxygen mask at a distance from the container. The driving device is coupled to the arm and passes the links out of the container. The links enclose a pivoting range extending as far as a level juxtaposition of the links. When extended, the arm adopts the level juxtaposition under the action of gravity for the lateral spacing of the relevant oxygen mask from the container.

The invention relates to an oxygen supply device with an oxygen source and with at least one oxygen mask, said oxygen mask beings conductively connectable to the oxygen source via a connection conduit. At least a section of the connection conduit between the oxygen mask and the oxygen source is formed by a film tube.

An extension mechanism for a passenger oxygen mask includes a guide block with defined channels to guide the rotation of a telescoping extension arm mechanism. After rotation, a rotating sleeve latch releases an internal telescoping arm that extends a pull flag for the passenger to grab and release the oxygen mask. A pull flag release mechanism releases the pull flag when the extension arm mechanism is fully extended. Combined spring biasing elements keep the pull flag secured in place while stowed and retract a pull flag retention pin at full extension.

An infant mask adapter for an emergency oxygen mask system may comprise a body extending between a base end and a face end, the body defining a cavity therewithin and open through the face end and the base end, a coupling portion proximate the base end, a shoulder portion between the coupling portion and the face end, and a bell mouth portion extending from the shoulder portion to the face end.

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.

The present disclosure relates to an emergency oxygen system (1) for an aircraft passenger with an oxygen mask (7), a controllable oxygen feed for the oxygen mask (7), and a control unit (5) for the control of the oxygen feed to the oxygen mask (7),
wherein the control unit (5) is configured to control the oxygen feed in a manner such that a demand oxygen pulse (21) flows into the oxygen mask (7) if a draw of breath (20) of the aircraft passenger is registered and that safety oxygen pulses (23) regularly flow into the oxygen mask (7) if no draw of breath of the aircraft passenger has been registered within a certain time window (T).
