Gas generator for an automobile airbag comprises supplementary outlets whose caps are blown when the gas generated by a pyrotechnic charge increases the pressure in a pressurized gas reservoir

摘要

Gas generator for inflating an automobile airbag, comprising a pressurized gas reservoir (3) and an initiator (12) that projects a plasma dart to perforate a cap on a primary opening (11) in the wall (7) between the gas reservoir and a gas outlet chamber (6) and to ignite a gas-generating pyrotechnic charge (14), comprises supplementary openings (50) in the wall whose caps are blown when the gas generated by the pyrotechnic charge increases the pressure in the reservoir.
