Abstract
A flexible oxygen supply system which can easily be adapted to different seat layouts and which is significantly improved with regard to test and maintenance possibilities. An oxygen module includes an oxygen source, a mask and a tube between the oxygen source and a mask. The oxygen module further includes fastening elements for fastening in a supply duct of an aircraft, and a locking element by means of which the cover of the oxygen module can be locked.
Claims17
An oxygen module for supplying oxygen to passengers of an aircraft, the aircraft comprising a supply duct, a releasable lining flap having a closed state that encloses the oxygen module in the supply duct and having an open state to expose the oxygen module, the oxygen module comprising:
- an outer housing comprising a locking tab;
- an oxygen source;
- a mask;
- a tube between the oxygen source and the mask;
- a fastening element for fastening the oxygen module in the supply duct of the aircraft;
- and
- a releasable cover including a locking element, the locking element being movable between a test configuration and an operation configuration;
- wherein the locking element is configured to engage the locking tab of the outer housing in response to movement of the locking element into the test configuration with the releasable lining flap in the closed state, wherein engagement of the locking element with the locking tab locks the cover of the oxygen module to the outer housing in a closed position;
- and
- wherein the locking element is configured to disengage the locking tab of the outer housing in response to movement of the locking element into the operation configuration, wherein disengagement of the locking element from the locking tab unlocks the cover of the oxygen module from the outer housing to enable opening of the cover in response to opening of the lining flap from the closed state to the open state.
An oxygen supply duct assembly comprising:
- a releasable lining flap having a closed state that encloses an oxygen module in a supply duct and having an open state to expose the oxygen module;
- a fastening structure;
- and
- the oxygen module including an outer housing comprising a locking tab, an oxygen source, a mask, and a tube between the oxygen source and the mask, the oxygen module having a releasable cover including a locking element that is movable from a first position to a second position while the releasable lining flap is in the closed state, the locking element configured to engage the locking tab of the outer housing in response to movement of the locking element into the second position, wherein engagement of the locking element with the locking tab locks the cover of the oxygen module to the outer housing in a closed position to prevent the cover of the oxygen module from opening during testing of a release of the lining flap, and the locking element configured to disengage the locking tab of the outer housing in response to movement of the locking element from the second position to the first position, wherein disengagement of the locking element from the locking tab unlocks the cover of the oxygen module from the outer housing to enable automatic opening of the cover in response to opening of the lining flap from the closed state to the open state;
- wherein the fastening structure positions the oxygen module in the longitudinal direction of the supply duct and secures it in the supply duct with a fastening element.
An aircraft comprising:
- an oxygen supply duct including a releasable lining flap and a fastening structure;
- and
- an oxygen module having an outer housing comprising a locking tab, a releasable cover including a locking element having a first position and a second position;
- wherein, when the locking element is in the first position, the locking element is disengaged from the locking tab of the outer housing and disengagement of the locking element from the locking tab unlocks the cover of the oxygen module from the outer housing to enable opening of the cover together with the lining flap in response to opening of the lining flap;
- wherein, when the locking element is in the second position, the locking element is engaged with the locking tab of the outer housing and engagement of the locking element with the locking tab locks the cover of the oxygen module to the outer housing in a closed position during testing of releasing of the lining flap;
- wherein the locking element is movable from the first position into the second position while the lining flap is closed;
- and
- wherein the fastening structure is formed so that the oxygen module is positionable in the longitudinal direction of the supply duct and secured in the supply duct via a fastening element.
