2011 Audi Q7 Air Bags & Restraints Problems

I AND FOUR CHILDREN BETWEEN THE AGES OF 2 AND 9 WERE DRIVING A 2011 AUDI Q7 ON A RIGHT LANE OF A STREET. WE HAD A GREEN LIGHT AND ANOTHER DRIVER IN A HONDA MINIVAN FROM THE OPPOSITE SIDE OF THE STREET MADE A LEFT TURN IN FRONT OF US WITHOUT YIELDING AND THOUGH I HIT THE BRAKE IMMEDIATELY, I WAS NOT ABLE TO AVOID CRASHING HEAD ON INTO THE OTHER CAR ON THE PASSENGER SIDE OF THE VAN. I AM TOLD THAT MY AUDI IS PROBABLY TOTALED BUT WE ARE WAITING TO HEAR THE OFFICIAL RESULTS. WE WERE ALL WEARING SEATBELTS BUT THE AIRBAGS ON MY AUDI NEVER DEPLOYED. WE ALL HIT OUR HEAD BACKWARDS. I HAVE A SPRAINED KNEE AND PAIN ON MY NECK, SHOULDERS AND BACK; ONE CHILD SEATED ON THE FRONT PASSENGER SEAT, AGE 9, HAS CHEST AND WAIST PAIN, ANOTHER CHILD, AGE 6, SEATED BEHIND THE DRIVER SEAT, HAD A CONCUSSION AND PAIN ON HIS HEAD AND RIGHT FRONT SHOULDER; ANOTHER 9 YEAR OLD, SEATED IN THE MIDDLE BACK SEAT, HAD A CUT IN HIS NOSE AND WAS BLEEDING, NOT SURE WHAT CAUSED IT AND ALSO HAS A NECK AND BACK PAIN; A 2 YEAR OLD HAD SOME CUTS AND BRUISES ON BOTH SIDES OF THE NECK CAUSED BY THE SEAT BELT AND HAD PAIN ON THE BACK OF THE NECK. WE WERE ALL TRANSPORTED TO THE HOSPITAL IN AN AMBULANCE AND TREATED. THE BURNING QUESTION EVERYONE HAD WAS "HOW COME THE AIRBAGS NEVER DEPLOY?". WHEN WE ASKED AUDI, WE WERE TOLD IT HAPPENS EVEN IN THE WORST ACCIDENTS AS LONG AS THE SENSOR DOES NOT SENSE DANGER. OUR CAR'S FRONT CRUMBLED INWARDS AND IT IS BEING CONSIDERED TO BE TOTALED, IF THAT IS NOT DANGER, I DON'T KNOW WHAT MORE SHOULD HAVE HAPPENED TO US FOR THE SENSOR TO SENSE DANGER. *TR
