PROBLEM TO BE SOLVED: To properly control an inflation speed, because the inflation speed of an air bag is too early, in the case of a weak shock in light collision or the like. SOLUTION: A gas generator means 8, 9, 10 jetting gas to a bag from a jet nozzle 12 of an inflator 1 by a gas jet signal of a control device is provided, a second gas generator device 13, 14 is provided in a gas jet chamber I having the jet nozzle 12, and when light collision is judged after the gas jet signal is output, a second gas jet signal is applied to act in the second gas generator device, and by moving a movable shutter 15 covering the second gas generator device, the jet nozzle 12 is partly closed, so as to control a gas jet amount. |
