Abstract
The device, which can be used to protect the pilots of high performance aircraft against the effect of accelerations, comprises a garment having at least trousers having pockets and a control member which supplies the pockets with compressed gas when the downwardly directed acceleration of the body exceeds a predetermined threshold. The control member is adapted to establish in the trouser pockets an overpressure from a positive acceleration threshold (BC), in accordance with a substantially linear law of variation from an origin (A) corresponding to a negative acceleration. The action of the compressed gas can be supplemented by that of a liquid contained in the pockets and also subjected to the pressure of the gas.
