I have been in an accident with no air bag deployed and wearing my seat belt. I was rear-ended by a vehicle doing 45 mph faster than mine. I had torn ligaments in my neck that took years to fully recover from.
An air bag might have reduced my injury to a sore neck.
P.S. I was in a 1964 Chevrolet C10 Pickup that I had installed seat belts in.
My forehead and shoulders bounced off the steering wheel so hard that the left lens of my eyeglasses popped out. My mother, who was with me, didn't have her seat belt on. She was bounced so hard against the ceiling she was knocked unconscious.
