The passenger oxygen mask is provided for emergency situations on board an aircraft. The mask body is designed collapsible at least in sections.

This simplifies the accommodation of the oxygen mask or even permits a smaller constructional size of the preparation device.

An emergency breathing device including a hood having use and storage configurations, which when compactly wrapped proximate to an oxygen control device for storage is recoverable for use. In use configuration, the hood is capable of being worn upon a user's head, which substantially surrounds the user's head. Hood surface beneath the user's head includes an opening lined with elastic material, which forms a seal about the user's neck at the opening when the hood is donned. An oxygen control device connected to a hood includes a valve body, an actuator, and an oxygen bottle. The valve body provides airflow communication with the interior of the hood, and the oxygen control device is connected to a plumbed breathable oxygen supply through a plumbed source disconnect means removably connected to the valve body. When connected, the oxygen control device permits airflow from the plumbed breathable oxygen supply and valve body to the interior of the hood. A cam within the valve body rotates with the operation of the actuator for engaging a piercing member to pierce the oxygen bottle, causing oxygen to flow from the oxygen bottle to the interior of the hood and forcing the plumbed source disconnect mechanism to simultaneously disconnect from the valve body. The user may therefore don the hood to receive breathable oxygen initially from the plumbed source and then from the oxygen bottle upon operation of the actuator and release from the plumbed source.

Provided herein is a hybrid system for generating oxygen on-board an aircraft for passengers and / or flight crew to breath. The system includes a first chemical oxygen generator component configured to promptly supply oxygen suitable for breathing upon an emergency situation arising and during an initial descent mode. Heat produced from the exothermic decomposition reactions inherent in several types of chemical oxygen generators can be harvested and feed to a second oxygen generator. The second oxygen generator is a solid electrolyte oxygen separation system that catalytically separates oxygen from air inside specialized ceramic materials at high temperatures, about 650° C. to 750° C., using electrical voltage. The ability to feed heat from the first oxygen generator to the second oxygen generator substantially reduces the lag time until the second ceramic oxygen generator is available to take over as the oxygen supply.
