The invention concerns a protective device comprising an airbag worn by a person, a pyrotechnic gas generator for inflating the airbag, and an actuator for the gas generator. The invention is such that the gas generator has a dual state combustion. Preferably, the generator is single-piece with single ignition. The invention device enables to provide a first inflating phase lasting about 60 ms at most, preferably between 30 and 50 ms; then a second phase maintaining inflation lasting at least a few seconds, preferably at least 4 s, more preferably still between 5 and 8 s.

Device for individual protection, comprising an airbag

The invention concerns an inflatable life buoy launcher gun for throwing, towards a shipwrecked person, a life buoy or life jacket folded in a sheathing body around a pyrotechnic gas generator. When the life buoy or life jacket reaches near the person, the life buoy or life jacket is inflated by means of gas generator gases. The folded life buoy or life jacket is launched from a launching tube provided with a firing handle and a launching gas generator.

A device for protecting, by impact absorption, the occupants of a motor vehicle in the event of a collision includes a pyrotechnic generator (2) of hot gases, the temperature of which at the outlet of the generator is equal to at least 1,800.degree. C. and a sealed or virtually sealed inflatable bag (3) fastened to the said generator. Communication between the bag (3) and the generator (2) is ensured by openings (27) with a constant cross-section arranged on the generator and by a deflector (28). The invention also relates to the use of a device of this type combined with a seat belt, in particular in order to improve the protection of motor vehicle drivers.
