FIELD: transport.
SUBSTANCE: soft envelope houses gas generation source and spring device for opening and filling as well as overpressure release valves. Proposed envelope represents, at least, three-layer design. Density of material of every next layer, starting from outer layer, decreases. Spring device allows simultaneous envelope opening in all directions while overpressure release valves allow releasing pressure with gradual increase.
EFFECT: optimum damping of lifting or falling object, reduced consumption of gas, accelerated inflation.
