Abstract

The invention concerns sealed flexible structures inflatable by pyrotechnic gas generators to be used as devices for obstructing pipes, as fireproof barriers, for lifting vehicles or as structural building elements. Said devices consist of a flexible inflatable structure (2), a pyrotechnic gas generator (4), a safety initiating set (6) and a folding or interface structure (11).
