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.

The invention claimed is: 1. A protective device comprising an airbag worn by a person, a pyrotechnic gas generator for inflating the airbag, and means for activating the gas generator, the gas generator having a first combustion chamber containing a first propellant ignited by an electric igniter,
The invention claimed is: 1. A protective device comprising an airbag worn by a person, a pyrotechnic gas generator for inflating the airbag, and means for activating the gas generator, the gas generator having a first combustion chamber containing a first propellant ignited by an electric igniter, the gases produced by combustion of the first propellant rapidly inflating the airbag during a first inflating phase lasting 60 ms at most, and a second combustion chamber containing a second propellant ignited by the hot gases generated by the combustion of the first propellant contained in the first combustion chamber, the combustion of the second propellant ensuring by means of a low, lasting flow rate, a second inflating phase maintaining inflation lasting at least 4 seconds. 2. The device as claimed in claim 1, wherein the gas generator is monoblock piece with single ignition. 3. The device as claimed in claim 1, wherein, each combustion chamber is equipped with a neck for regulating the flow rate. 4. The device as claimed in claim 1, wherein the first inflating phase lasts between 30 and 50 ms. 5. The device as claimed in claim 1, wherein the second phase lasts between 5 and 8 s. 6. The device as claimed in claim 1, wherein the means for activating the gas generator is electronic. 7. The device as claimed in claim 6, wherein the means for activating the gas generator comprises a sensor-transmitter module placed on a vehicle which transmits information to a receiver-igniter module placed on the person, either of these modules comprising a discriminating component. 8. The device as claimed in claim 7, wherein information is transmitted between the two modules by a radio-encoded or wire link. 9. The device as claimed in claim 7, wherein the sensor-transmitter module comprises a sensor component consisting of a triaxial accelerometric sensor. 10. The device as claimed in claim 7, wherein information is transmitted between the two modules by a radio-encoded link, the sensor-transmitter module being equipped with a component for producing the code, and the receiver-igniter module being equipped with a component for acquiring the code. 11. The device as claimed in claim 1, wherein the means for activating the gas generator comprises a discriminating component taking into account a parameter for not activating the gas generator, consisting of the value of the vehicle speed greater than a threshold speed in the absence of a shock. 12. The device as claimed in claim 1, wherein the various elements forming the gas generator are materials chosen from the group consisting of composite materials and thermoplastics filled with fibers or powders.
