Abstract
Apparatus for inflating pockets or envelopes by a pyrotechnic composition, comprising a device contng. the composition and intended to ensure the necessary confinement of the combustion. Permits the utilisation of pyrotechnic composition which can only be burnt regularly in a confined space, and is particularly suitable for use in protective devices which function by inflation of an envelope.
