Abstract

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.

First claim

What is claimed is:

1. A vehicle, comprising:
an internal cabin;
a plurality of passenger service units (PSUs) within the internal cabin;
an emergency oxygen system within the internal cabin, wherein the emergency oxygen system is distinct and separated from the plurality of PSUs;
one or more stowage bin assemblies within the internal cabin, wherein one or more of the plurality of PSUs are disposed between the one or more stowage bin assemblies and the emergency oxygen system; and
a partition wall that separates the emergency oxygen system from the plurality of PSUs, wherein the emergency oxygen system is mounted to a first side of the partition wall, and the plurality of PSUs are mounted to a second side of the partition wall opposite from the first side.

2. The vehicle of claim 1 , wherein the emergency oxygen system comprises a plurality of oxygen assemblies, and wherein the plurality of oxygen assemblies are uncoupled from seat pitch.

3. The vehicle of claim 2 , wherein each of the plurality of oxygen assemblies comprises a mask and a fluid conduit.

4. The vehicle of claim 3 , wherein the emergency oxygen system further comprises an oxygen supply in fluid communication with the plurality of oxygen assemblies.

5. The vehicle of claim 4 , wherein the oxygen supply comprises an oxygen canister fluidly coupled to the fluid conduit.

6. The vehicle of claim 4 , wherein the oxygen supply comprises an oxygen tank fluidly coupled to a plurality of fluid conduits via a manifold.

7. The vehicle of claim 2 , wherein the emergency oxygen system further comprises a rail extending along a length of the internal cabin, wherein the rail retains the plurality of oxygen assemblies.

8. The vehicle of claim 1 , wherein the emergency oxygen system is disposed between a sidewall of the vehicle and the plurality of PSUs.

9. The vehicle of claim 1 , wherein each of the plurality of PSUs comprises one or more attendant lights, one or more gaspers, and one or more reading lights.

10. A method, comprising:
providing a plurality of passenger service units (PSUs) within an internal cabin of a vehicle;
providing an emergency oxygen system within the internal cabin, wherein the emergency oxygen system is distinct and separated from the plurality of PSUs;
disposing one or more of the plurality of PSUs between one or more stowage bin assemblies and the emergency oxygen system; and
separating the emergency oxygen system from the plurality of PSUs by a partition wall, wherein the emergency oxygen system is mounted to a first side of the partition wall, and the plurality of PSUs are mounted to a second side of the partition wall opposite from the first side.

11. The method of claim 10 , wherein the emergency oxygen system comprises a plurality of oxygen assemblies, wherein each of the plurality of oxygen assemblies comprises a mask and a fluid conduit.

12. The method of claim 11 , further comprising fluidly coupling an oxygen supply with the plurality of oxygen assemblies.

13. The method of claim 12 , wherein said fluidly coupling comprises fluidly coupling an oxygen canister to the fluid conduit.

14. The method of claim 12 , wherein said fluidly coupling comprises fluidly coupling an oxygen tank to a plurality of fluid conduits via a manifold.

15. The method of claim 11 , further comprising retaining the plurality of oxygen assemblies by a rail extending along a length of the internal cabin.

16. The method of claim 10 , further comprising disposing the emergency oxygen system between a sidewall of the vehicle and the plurality of PSUs.

17. A vehicle, comprising:
an internal cabin;
a plurality of passenger service units (PSUs) within the internal cabin;
an emergency oxygen system within the internal cabin, wherein the emergency oxygen system comprises:
a plurality of oxygen assemblies, wherein each of the plurality of oxygen assemblies comprises a mask and a fluid conduit;
a rail extending along a length of the internal cabin, wherein the rail retains the plurality of oxygen assemblies;
an oxygen supply in fluid communication with the plurality of oxygen assemblies, wherein the emergency oxygen system is distinct and separated from the plurality of PSUs;
one or more stowage bin assemblies within the internal cabin, wherein one or more of the plurality of PSUs are disposed between the one or more stowage bin assemblies and the emergency oxygen system; and
a partition wall that separates the emergency oxygen system from the plurality of PSUs, wherein the emergency oxygen system is mounted to a first side of the partition wall, and the plurality of PSUs are mounted to a second side of the partition wall opposite from the first side.

18. The vehicle of claim 17 , wherein each of the plurality of PSUs comprises one or more attendant lights, one or more gaspers, and one or more reading lights.

19. The vehicle of claim 17 , wherein the plurality of oxygen assemblies are uncoupled from seat pitch.

20. The vehicle of claim 17 , wherein the emergency oxygen system is disposed between a sidewall of the vehicle and the plurality of PSUs.
