HM first of all good to know you are safe. There may have been a defect in the design, production or installation of the air bags. You can certainly bring a legal action for malfunctioning airbags but first seek a practising lawyers advice, you'll need an accident report, a medical report to claim for personal injury as well as have technical tests conducted to support your case of the airbags not deploying under conditions that so required. I wish I could help you out but I am way out of my jurisdiction here ;-) The sooner you see a lawyer about this the better to ensure your matter is not time barred as Im not sure about the statute of limitations here.
