Abstract:
1. An air bag system, comprising: an electronic control unit connected to a power source and an impact detecting sensor; a bus line having a plurality of loop wires passing through the electronic control unit to supply and transmit currents and required information; and a plurality of module cases, each module case accommodating a gas generator, connected to the electronic control unit via the bus line, and an air bag, wherein, each gas generator is operationally connected to the bus line at predetermined portions of the bus line, each gas generator is provided with one or more electric igniters connected to the bus line by a plurality of conductors, and the one or more electric igniters includes a heat generating portion, a priming adapted to be ignited by the heat generating portion, a capacitor, and an integrated circuit recorded with information to exhibit required functions, and the one or more igniters is supplied with a current for igniting the priming through the capacitor, and a time period for supplying the current is from a point where a current value reaches a value corresponding to 5% of the maximum current value to a point where the current value reduces to the value corresponding to 5% of the maximum current value, which is within 500 μsec.
