Airbags?

[Ozone]

I think installing an airbag would be a bad idea.

Airbags are tuned to the vehicle which they are fitted to with regards to bag size and shape, the amount of propelant used and when the sensor desides to trigger the bag. These factor are tuned depending on how the vehicle deforms in an accident and the layout of the vehicle - sit low and long in a sports car and high and upright in an SUV/MPV.

You'll probably end up with either A) the bag going off and deflating too quickly, doing nothing other than burning your face or B) not deflating soon enough and the being knocked out as the steering column moves (if the column moves back with the bag fully inflated it will be like being hit in the face by a block of concrete).

If you really want an airbag your are better off driving a different car.
