PURPOSE:To ignite surely plural squibs starting in order with time delay. CONSTITUTION:A power source 200 to feed electric energy to sqibs 115-123 of plural safety devices respectively, a safety sensor 209 to control the power feeding between the power source 200 and the squibs 115-123 inducing to a specific acceleration, a microcomputer 105 to operate the squibs 115-123 in a specific order, and an energy reserving circuit 130 in which the electric energy is fed and accumulated when the power source 200 and the squibs 115-123 are in the power feeding condition, are provided. And when the power source 200 and the squibs 121 and 123 are cut off prior to finishing all the operations of the sqibs 121 and 123, the energy reserving circuit 130 feeds the electric energy to the squibs 121 and 123, so as to operate all the operations of the squibs 115-123. |
