A device for regulating breathing gas delivered to a user, comprising a gas circuit comprising a main line having at least an upstream end intended to be connected to at least one gas source and a downstream end intended to be connected to at least one user station such as a mask, the main line comprising at least one electromechanical control valve configured to regulate the gas pressure between the upstream and the downstream, the circuit comprising a secondary line comprising an upstream end intended to be connected to at least one gas source and a downstream end intended to be connected to the same user station(s), the secondary line comprising at least one auxiliary member for regulating the gas flow, the device comprising a switching system configured to control the flow of gas between the upstream and the downstream of the circuit via the main line or via the secondary line, characterized in that the auxiliary member for regulating the secondary line is a pneumatic pressure regulator.

A device for latching a door of an oxygen mask container in an aircraft cabin includes a door for an oxygen mask container having an inner side, outer side and hinge, a first latching device attached to the inner side, and a second latching device movable relative to the first latching device to selectively engage or disengage the second latching device. A retaining element is attachable to a structural part inside the oxygen mask container. A test control device on the inner side of the door includes a movable hook element and can move the hook element to a first or second position. The hook element can engage the retaining element in the first position to restrict an opening degree of the door. The hook element is placed in the second position such that when the door is opened, the hook element is moved past the retaining element.

A device for supplying breathing gas to a user includes: a mask having a breathing opening; and a bag having a bag opening that is connected to the breathing opening in fluid communication, wherein the device further includes an adjustable exhalation valve, wherein the adjustable exhalation valve is in fluid communication with the bag. Thus, the device for supplying breathing gas to a user provides protection against hyperventilation, toxic gases and smoke.

Locking device comprising: a support, a first locking member and a second locking member, the first locking member being mounted on the support and configured to move between a locked position and an unlocked position, an intermediate member movable between a retaining position and a release position, the intermediate member in the retaining position retaining the first locking member in the locked position, and a shape-memory member, the shape-memory member being connected to the intermediate member and configured to move the intermediate member to the release position when the shape-memory member is activated.

An overhead aircraft passenger service unit, which is configured to be placed above the passenger seats within an aircraft cabin, comprises at least one cavity for housing at least one oxygen mask and at least one removable cover, which at least partially covers an opening of the cavity. The removable cover houses and/or supports at least one functional component.

A breathing system for an aircraft crew member or passenger may include a face-fitting device, a storage area added to a seat headrest for retaining the face-fitting device in a storage position apart from the head, and a back portion for retaining the face-fitting device on the user's head when the breathing system is used. The back portion is retained on the headrest by a removable fixing mechanism when the face-fitting device is in the storage position, and the removable fixing mechanism is released upon the tightening the face-fitting device on the user's head.

An aircraft passenger service unit kit includes an overhead passenger service unit panel including at least one hinge pin extending along an edge portion of the overhead passenger service unit panel and an elastic fixing element for fixing the overhead passenger service unit panel to an aircraft support structure. The fixing element includes at least one first end, which is configured for rotatably connecting with the at least one hinge pin; and at least one opposing second end, which is configured for engaging with a mounting rail of the aircraft support structure. The overhead passenger service unit panel further includes a forcing element, which is configured for acting onto the fixing element generating a tension within the fixing element for securely fixing the at least one second end of the fixing element to the mounting rail.

An aircraft emergency oxygen supply system comprises a passenger oxygen mask for supplying oxygen to a passenger wearing the passenger oxygen mask; an oxygen source for supplying oxygen to the passenger oxygen mask; a breath sensor for detecting breaths of the passenger wearing the passenger oxygen mask; and a controller for controlling the supply of oxygen from the oxygen source to the passenger oxygen mask. The controller is configured for operating in a normal breathing mode, which includes supplying a normal breathing amount of oxygen (V.sub.N) from the oxygen source to the passenger oxygen mask at every breath of the passenger wearing the passenger oxygen mask; deriving a breathing frequency indicator from a plurality of successive breaths of the passenger; and switching into a fast or into a low breathing mode if the breathing frequency indicator indicates a breathing frequency above or below predefined frequency thresholds.

A vehicle includes an internal cabin, a plurality of stowage bin assemblies within the internal cabin, a plurality of passenger service units (PSUs) within the internal cabin, and an emergency oxygen system within the internal cabin. The plurality of stowage bin assemblies are uncoupled (for example, separate and distinct) from one or both of the plurality of PSUs or the emergency oxygen system. In an example, the plurality of stowage bin assemblies are uncoupled from the emergency oxygen system. In another example, the plurality of stowage bin assemblies are uncoupled from the plurality of PSUs. In another example, the plurality of stowage bin assemblies are uncoupled from both the plurality of PSUs and the emergency oxygen system.
