Air Bag Not Deploy problems of the 2001 Kia Motor Sportage

I was driving a kia Sportage 2001 and was struck in the rear by a tractor trailer. The impact was so great it broke the back support of my seat. The truck forced me into the vehicle in front of me so hard that I crumbled the trunk of that vehicle. In all 5 vehicles received damage. My vehicle was totaled. My seat broke and my airbags including a knee airbag did not deploy. I received whiplash to the neck and damage to my right leg. I feel that had my airbags deployed I would not have received the damage to my leg. Also I believe had my seat back support stayed upright I would not have received the injuries as bad.

The vehicle veered to the right and flipped over three times. The air bags never deployed.

While driving approximately 35 mph vehicle was involved in a full frontal crash. Both frontal air bags failed to deploy, resulting in injury to driver. Vehicle has not been examined to determine cause of failure. Please provide any additional information / documentation.

Vehicle crashed into the front end of another vehicle and both airbags failed to deploy, consumer suffered from soft tissue damage, cervical lumbar sprain, numbness of left arm, and stiffness of upper and lower back.

While travling at 35-40 mph and running into a tree head-on air bags did not deploy. Has not contacted dealer.
