ABSTRACT:
An airbag device includes a squib, an ignition circuit, and a noise protection circuit. The noise protection circuit includes two zener diodes whose cathodes are facing each other and connected with each other. Further, the noise protection circuit is connected in parallel with the ignition element to thereby protect the ignition circuit from noise. This decreases the number of components in the noise protection circuit to thereby achieve the compact and low-cost airbag device.
