ABSTRACT:
A system of protection by modeling and/or immobilization comprises at least one flexible and leakproof envelope, a plurality of resilient and deformable balls therein, and means for establishing a vacuum inside the envelope. Two elastic skins joined in leak-proof fashion by their peripheries constitute the envelope, inside which vacuum is created by a vacuum-generating unit including a gas generator. This system can be used in particular for transporting the wounded, or as a seat, the latter being constituted by one or more envelopes.
