Abstract:
An inflator for inflating an airbag, comprising:a pressure container filled with a high-pressure gas higher than an atmosphere and having a gas exit at one end thereof, said gas exit being opened upon receipt of a first shock wave, and a shock wave generator provided at the other end of the pressure container for generating the first shock wave toward the gas exit, and including a tube having a distal end and a proximal end and being filled with a gas with a pressure lower than that of the high-pressure gas in the pressure container, and an initiator provided at the proximal end of the tube for emitting a second shock wave toward the distal end of the tube when the initiator is actuated, said distal end having a closure disk arranged to open upon receipt of the second shock wave to generate the first shock wave toward the gas exit of the pressure container.
