A securement mechanism for a storage compartment in a seat headrest may comprise a housing tray and a first latch disposed in the housing tray. A release button may be disposed in the housing tray and may contact the first latch. The release button may be configured to be substantially coplanar with the housing tray when the securement mechanism is in a secured position.

An emergency equipment for an aircraft comprising: a respiratory mask (5) comprising a harness (6), the respiratory mask (5) being adapted to be applied in a use position around the nose and the mouth of a user, a stowage box (1) comprising a housing, the housing having side walls (2), a back wall (3) and an opening (4) opposite to the back wall (3), the side walls (2) and the back wall (3) defining an internal space (32) adapted to stow the respiratory mask (5) in a stowage position. The emergency equipment further comprises a support (10) supporting the respiratory mask (5) in the stowage position. The support (10) comprises a main plate (11) which is rigid and which is movable with respect to the stowage box (1) between a backward position and a frontward position along a longitudinal direction. The support (10) is in the backward position in the stowage position of the respiratory mask (5).

A release button may be disposed in the housing tray and may contact the first latch. The release button may be configured to be substantially coplanar with the housing tray when the securement mechanism is in a secured position.

An emergency oxygen system for an internal cabin of a vehicle includes a housing including one or more compartments. One or more oxygen assemblies include a mask and a fluid conduit. The mask is configured to be stowed within and deployed from the one or more compartments. A door is moveably secured to the housing. The door is configured to pivot in an outboard direction from a closed position to an open position during a deployment event. One or more pouches can be secured to an interior surface of the door. Coiled tubing of the fluid conduit is retained by the one or more pouches when the mask is stowed within the one or more compartments. An alert device can be operatively coupled to the one or more oxygen assemblies. The alert device is configured to emit a response indicating that oxygen is flowing to the mask.

A wall mounted stowage compartment for a passenger cabin of an aircraft includes a housing having a rearwardly facing wall mounted to a forwardly facing interior monument wall. The stowage compartment is located under an aft most passenger seat adjacent to the forwardly facing interior monument wall. The stowage compartment includes a stowage compartment drawer, and a protective breathing equipment compartment is mounted to a side wall of the aircraft cabin monument, and includes a forwardly facing edge that follows a contour of the forwardly facing wall of the aircraft cabin monument extending from a forwardly facing recess to the floor of the cabin.

A device for latching a door of an oxygen mask container in an aircraft cabin includes a door for an oxygen mask container having an inner side, outer side and hinge, a first latching device attached to the inner side, and a second latching device movable relative to the first latching device to selectively engage or disengage the second latching device. A retaining element is attachable to a structural part inside the oxygen mask container. A test control device on the inner side of the door includes a movable hook element and can move the hook element to a first or second position. The hook element can engage the retaining element in the first position to restrict an opening degree of the door. The hook element is placed in the second position such that when the door is opened, the hook element is moved past the retaining element.

A vehicle includes an internal cabin. A plurality of passenger service units (PSUs) are within the internal cabin. An emergency oxygen system is within the internal cabin. 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.

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 oxygen system for an aircraft may have a chemical oxygen generator; an oxygen mask; and a tube assembly extending from the chemical oxygen generator to the oxygen mask. The tube assembly may have a first tube and a second tube. The first tube defines a fluid conduit that fluidly couples the chemical oxygen generator to the oxygen mask in response to being in use. The second tube may be configured to house a plurality of lights therein.
