DESCRIZIONE
The invention relates to a portable device (1), consisting of internal cells (3) which, by swelling, unfold in the form of a balloon around the carrier (6), which is moored there by straps and harnesses ( 7, 8 and 9). Disengaged by the lever (20) of the mechanism (22), the hook (23), driven by a carriage (26) subjected to the traction of the springs (27), pulls on the cords (28 and 29) of the housings (10) percussion of gas cylinders (12). Then, under the pull of a spring (25), the hook is lifted releasing the cords whose stall is facilitated by a stop ramp (30). By their recoil, the two forks of the axis of the carriage (31) then release the carabiners (35) of the straps (34). The device according to the invention is particularly intended to prevent, on water, the immersion of the castaway and, in the mountains, the burial by avalanches.
