An onboard oxygen system for aircraft includes an oxygen source, a regulator connected to the oxygen source, and an oxygen mask connected to the regulator. The oxygen source is stored in a cavity in a passenger seat armrest. The oxygen mask is stored in a mask storage compartment attached to the armrest. The oxygen mask is deployed for use through an opening in the mask storage compartment.

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.

A system may include a manifold. The manifold may include a body and a rupture disc. The body may include first connector connected to a pressurized source, a second connector, and a third connector. The body may include hollow pathway network including a first path portion extending from the pressurized source to a pathway junction, a second path portion extending from the pathway junction to the second connector, and a third path portion extending from the pathway junction to the third connector. The first path portion may include a bend. The rupture disc may be positioned between the bend and the pathway junction. When the rupture disc is in an unruptured state, the rupture disc may seal the first path portion from the other path portions. When the rupture disc is in a ruptured state, the rupture disc may allow a flow from the pressurized source to the third connector.

Within examples, a system to provide filtered air to an enclosure for a passenger of a vehicle is described that includes a collapsible canopy hood attachable to a support structure of a vehicle, and a filter unit mounted to the support structure of the vehicle and having an output coupled to the collapsible canopy hood. The filter unit includes an air filtration component to filter air that is then output to the collapsible canopy hood.

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.

A system for delivering breathing gas to passengers includes: a face mask including a face part having a breathing cavity, a tube configured to be supplied by pressurized breathing gas, and a reservoir bag disposed between the tube and the face part. A passage connects the reservoir bag to the breathing cavity so that the system is configured to supply the breathing cavity through the reservoir bag. The reservoir bag includes a front portion and a back portion. The front portion is connected to the face mask, and the system has a stowed configuration and a deployed configuration. In the stowed configuration, the reservoir bag is maintained folded between a backing and the face part.

A protective hood for air travel including a plurality of deformable partitions coupled to each other defining an inner cavity, wherein in a folded position the inner cavity is collapsed to a negligible size and in an unfolded position the inner cavity is configured to comfortably confine an human head, wherein one of the partitions includes a deformable opening configured to be stretched and fit over a head, and at least one coupling mechanism configured to attach one of the deformable partitions to an aircraft seat.

Within examples, a system to provide filtered air to an enclosure for a passenger of a vehicle is described that includes a collapsible canopy hood attachable to a support structure of a vehicle, and a filter unit mounted to the support structure of the vehicle and having an output coupled to the collapsible canopy hood. The filter unit includes an air filtration component to filter air that is then output to the collapsible canopy hood.
