2012 NISSAN MAXIMA Seat Belts Problems

ME AND MY WIFE WERE TRAVELING NORTHBOUND IN OUR 2012 NISSAN MAXIMA AROUND 30MPH ON WESTERN AVENUE IN CHICAGO WHEN SUDDENLY A FORD FOCUS 2007 THAT RAN A STOP SIGN TRAVELING EAST BOUND ON ROSEMONT AVENUE T-BONED US ON DRIVER'S SIDE. AS OUR CAR WAS MOVING AT A SIGNIFICANT SPEED IT STOPPED AFTER CRASHING INTO A FIRE HYDRANT WHICH WAS ON THE CORNER OF THE INTERSECTION. MY WIFE WAS TAKEN TO A HOSPITAL IN AN AMBULANCE WITH ARM AND BACK INJURIES AND I ALSO HAD INJURIES ON MY LEFT ARM, SHOULDER AND LOWER BACK. MY MAIN CONCERN IS WHY NONE OF THE AIRBAGS DEPLOYED IF THE CAR WAS TRAVELING AT A SPEED MORE THAN 20 MPH AND HIT A SOLID OBJECT(FIRE HYDRANT). BOTH OF US WERE WEARING SEAT BELTS. THE CAR WAS DECLARED TOTALED BY BOTH THE INSURANCE INVESTIGATORS. I AM GLAD THAT THIS DID NOT HAPPENED AT A HIGH...
