Abstract
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.
Claims20
An oxygen system for an aircraft, the oxygen system comprising:
- a chemical oxygen generator;
- an oxygen mask;
- and
- a tube assembly comprising a first tube and a second tube, each of the first tube and the second tube extending from the chemical oxygen generator to the oxygen mask, the first tube defining a fluid conduit that fluidly couples the chemical oxygen generator to the oxygen mask in response to being in use, the second tube configured to house a plurality of lights therein,
- wherein the first tube and the second tube define a chamber radially therebetween, and wherein the plurality of lights are disposed within the chamber, wherein the first tube comprising an outer circumferential surface and the second tube comprising an inner circumferential surface, the chamber is positioned between the outer circumferential surface of the first tube and the inner circumferential surface of the second tube, and wherein at a section of the tube assembly, and the chamber extend around the entire outer circumferential surface of the first tube to surround the first tube at the section of the tube assembly.
2 more elements
An oxygen system for an aircraft, comprising:
- an oxygen mask;
- a tube assembly comprising a first tube and a second tube, the first tube defining a fluid conduit configured to transfer a fluid to the oxygen mask, the first tube and the second tube defining a chamber therebetween;
