Assembly comprising a respiratory mask and a stowage device, method for stowing a respiratory mask and method for providing a respiratory mask

Method for stowing a respiratory mask wherein an assembly comprising the respiratory mask is intended to be arranged in particular in a cockpit of an aircraft having a pressurized cabin in order to supply breathing gas to a crew member, the respiratory mask having a face cover and a harness, said assembly further comprising a stowage device, the stowage device comprising a base and a platform, the platform comprises a main element movable relative to the base between a retracted position and a protruding position, the platform has a flattened configuration and an expanded configuration, wherein said method comprises:

• a) placing the main element (in the protruding position and the platform in the expanded configuration, the platform having a first longitudinal dimension along a longitudinal direction in the expanded configuration,
• b) bringing the respiratory mask to a stowage position where the harness forms a loop extending around the platform so as to hold the respiratory mask on the platform,
• c) moving the main element into the retracted position and placing the platform in the flattened configuration, the platform having a second longitudinal dimension along the longitudinal direction in the flattened configuration, the second longitudinal dimension being smaller than the first longitudinal dimension.
