The breathing mask further comprises an extensible harness (4) having end portions (5) connected to said rigid portion and including an inflatable element (6) connected to a source (7) of pressurized gas through a manually operable valve which delivers the pressurized gas to the inflatable element for extending the harness when actuated, and which reduces the pressure in said inflatable element to retract the harness and to cause the rigid portion to engage the face of the user when released. The source of pressurized gas is an autonomous container (7) supported by the rigid portion and containing the pressurized gas. ## Claims ### Claim 1 Breathing mask for aircraft crewmember or passenger comprising a rigid portion to be fit against the face of a user, said rigid portion comprising elements to bring a breathable gas to the user, said breathing mask further comprising an extensible harness having end portions connected to said rigid portion and including an inflatable element connected to a source of pressurized gas through a manually operable valve which delivers the pressurized gas to the inflatable element for extending the harness when actuated, and which reduces the pressure in said inflatable element to retract the harness and to cause the rigid portion to engage the face of the user when released, wherein said source of pressurized gas is an autonomous container supported by the rigid portion and containing the pressurized gas. ### Claim 2 (depends on 1) Breathing mask according to claim 1, wherein the autonomous container is sealed before use and the breathing mask further comprises a manually operable striker adapted to pierce the container the first time the user actuates the valve to inflate the inflatable element. ### Claim 3 (depends on 2) Breathing mask according to claim 2, wherein the autonomous container is a disposable bottle to be changed after use. ### Claim 4 (depends on 2) Breathing mask according to claim 2, wherein a visible sign is disposed on, said visible sign having a different appearance when the autonomous container is sealed and when the autonomous container is pierced. ### Claim 5 (depends on 4) Breathing mask according to claim 4, wherein the visible sign is a seal which is broken by the striker when it pierces the autonomous container. ### Claim 6 (depends on 2) Breathing mask according to claim 2, wherein said striker is operable through a lever, said lever being adapted to move said valve to the position to deliver the pressurized gas at the same time that is moves the striker to pierce the container. ### Claim 7 (depends on 1) Breathing mask according to claim 1, wherein a pressure reducer is inserted between the autonomous container and the inflatable portion. ### Claim 8 (depends on 7) Breathing mask according to claim 7, wherein a security valve is disposed between the pressure reducer and the inflatable portion, said security valve being adapted to limit the pressure in the inflatable portion below 90, Newton per square centimeter. ### Claim 9 (depends on 7) Breathing mask according to claim 7, wherein the autonomous container is adapted to inflate the harness many times. ### Claim 10 (depends on 9) Breathing mask according to claim 9, wherein the autonomous container is distinct from said elements bringing a breathable gas to the user. ### Claim 11 (depends on 9) Breathing mask according to claim 9, wherein the autonomous container is rigidly fixed to the rigid portion. ### Claim 12 (depends on 7) Breathing mask according to claim 7, wherein the autonomous container is distinct from said elements bringing a breathable gas to the user. ### Claim 13 (depends on 1) Breathing mask according to claim 1, wherein the autonomous container is adapted to inflate the harness many times. ### Claim 14 (depends on 1) Breathing mask according to claim 1, wherein the autonomous container is distinct from said elements bringing a breathable gas to the user. ### Claim 15 (depends on 1) Breathing mask according to claim 1, wherein the autonomous container is rigidly fixed to the rigid portion.
