An onboard oxygen system for aircraft includes an oxygen source, a regulator connected to the oxygen source, and an oxygen mask connected to the regulator. The oxygen source is stored in a cavity in a passenger seat armrest. The oxygen mask is stored in a mask storage compartment attached to the armrest. The oxygen mask is deployed for use through an opening in the mask storage compartment.

A stowage device of emergency equipment for aircraft crewmember, the stowage device comprising a housing, the housing extends along a longitudinal direction and has side walls, a back wall and an opening opposite to the back wall, the side walls and the back wall define an internal space adapted to stow a respiratory mask in a stowage position, the side walls extend along the longitudinal direction up to a front edge delimiting the opening. One of the side walls is an adjustable wall. The housing comprises a frame and a movable element. The movable element is mounted on the frame and is movable between a retracted position and a protruding position. The movable element comprises a main movable panel and the adjustable wall includes the main movable panel.

A harness for a breathing apparatus includes an interface member (6) having an elongated shape and being configured for receiving a container of breathable gas of the breathing apparatus. A hip belt (2) is connected to the interface member at a first region (50) of the interface member. A first shoulder belt (16) and a second shoulder belt (18) are connected to the interface member at the first region and at a second region (52) of the interface member. The hip belt and/or the first and second shoulder belts comprise at least one first moulded heat resistant plastic material.

A mask has to possess sufficient electrostatic charges in order to maintain a filtering effect of the mask using static electricity. However, an electrostatic property naturally decreases as an amount of the electrostatic charges decreases when contacting a human body or exposed to the air. Resultantly, as an initial electrostatic filtering effect gradually decreases, an initially intended function of the mask is not implemented.

The present invention relates to a static electricity recharging device for a mask, which allows the mask to be reused by recharging reduced or removed electrostatic charges in the mask.

A self-contained breathing apparatus includes at least one air tank having a regulator, and a back plate configured to removably receive the air tank. The back plate has a plate having a tank engagement surface for engaging at least a portion of an air tank, a receiving cradle on the plate configured to receive the regulator of an air tank, and a locking mechanism associated with the cradle and/or the plate for releasably locking the regulator and/or the cradle relative to the plate. The locking mechanism has at least one locking member configured to move between a first locked position, wherein the locking member engages the regulator and/or cradle to restrict removal of the regulator and/or the receiving cradle from the plate, and a second unlocked position, wherein the locking member disengages from the regulator and/or the cradle to permit removal of the regulator and/or the cradle from the plate.
