Abstract
An actuator for inflating a vehicle air bag includes an acceleration sensor, a computer for judging a vehicle collision according to a signal of the acceleration sensor, a plurality of squibs for inflating the air bag, an electronic switch unit connected in series to a power source and the squibs, a drive circuit for driving the electronic switch unit to connect the power source and the squibs when the computer judges a vehicle collision. The drive circuit has a serial signal generator, a serial-parallel converter and a forbidding circuit. The serial signal generator generates a serial signal composed of a prescribed number of serial bit signals in a prescribed order, and the serial-parallel converter the serial signal to the prescribed number of parallel bit signals. The forbidding circuit forbids the electronic switch unit connecting the power source and the squibs except the parallel bit signals coincide with the prescribed order of the serial signal.
