the output stage using the fet will be the one to use,but saying that the circuit could be simplified a little -theres no reason why you cant use a relay driven by a transistor-but the other way is that its all solid state no moving parts to wear out,also pin 2-the trigger signal either needs to be edge triggered or suitably debounced to prevent multiple trigger signals.....

another addition could be a divide by n counter dependant on how many airbags are to be triggered using a 4017......if you did that then each output from the 4017 could trigger your airbags in turn one after the other.....
