Patent ID: 7309079

Claim:
An air bag system, comprising: an electronic control unit adapted to be connected to a power source and an impact detecting sensor; a plurality of module cases, each accommodating a gas generator and an air bag therein; a bus line including a plurality of loop wires which extend from the electronic control unit to transmit signals to one or more selected air bags, the gas generator in each of the plurality of module cases being connected to the bus line at predetermined portions of the bus line, wherein, each gas generator includes, an igniter provided with a heat generating portion and a priming in contact with the heat generating portion, and the igniter is connected to the bus line, and a capacitor and an integrated circuit recorded with information peculiar to each igniter being provided between the igniter and the bus line, such that the integrated circuit generates a signal that allows the capacitor to discharge an electric current for activating the igniter to ignite the priming.
