Front Driver Side Air Bag Inflator problems of the 1996 Chevrolet S10

I was driving a chevy s-10 when a lady pulled in front of me. I was doing the speed limit of about 55-60 mph. I ended up hitting her car and in turn my truck rolled over several (6-10) times. The whole truck from bumper to bumper and side to side and top to bottom was destroyed. The truck was totaled. The seatbelt did its job but no airbag came out. I bought the truck used from a local car dealer here in concord 2 years ago. I am very bruised and cut and very upset that just maybe if that airbag had worked I would not have gotten all that glass along with everything else flying my way. I know that an airbag works when it is hit just right, but as I stated there is no part on that truck that was not hit including the front bumper as it is almost off the truck. The insurance company is taking control of the truck as we speak but there are numerous pictures and witnesses to this. I just want to know if something was wrong and that I did not put all my safety assurances into this airbag. Thank-you for your time. Christine floro.
