Seat Broken problems of the 2014 Ford Focus

While commuting to work on the highway and coming to a stop due to traffic the vehicle was hit from behind at appx 50mph. My wife saw the imminent impact a split second before it happened & tried to apply the brakes as hard as possible so as not to hit the car in front of her (appx 20-25 feet away). Nonetheless, the impact was too great. It totally destroyed the rear of our car and blew out the back glass. It also pushed our car into the car in front which damaged the right front, bent the hood in the front middle section, made the undercarriage pop out, and broke the radiator. There may have been additional front end damage but the hood was not opened at the time. What's worse, in all of this, the vehicle's air bags never deployed! so, my wife hit her head on the steering wheel twice. Moreover, the seat back broke which created a potentially paralyzing and/ or deadly condition due to her body's momentum as opposed to the car's momentum (I. E. , she had no back stability)! lastly, her knees were jammed into some portion of the dash/ steering column. My wife has sustained some injuries and we are currently getting her treated.
