2005 Chevrolet Impala Seats Problems

MY WIFE WAS SITTING STILL AT A RED LIGHT ON A ROAD WITH A 50MPH SPEED LIMIT. THE OTHER DRIVER DID NOT SEE THE RED LIGHT OR HER CAR & REAR ENDED HER AT FULL SPEED. THE BACK OF HER SEAT SNAPPED ALL THE WAY BACK AND THE BOTTOM OF THE SEAT LODGED UPWARD CAUSING HER THIGHS AND PELVIC AREA TO BE SEVERELY COMPRESSED BETWEEN THE STEERING WHEEL AND SEAT WHILE HER HEAD WAS JOSTLED AROUND VIGOROUSLY DUE TO THE LACK OF BACK SUPPORT. HER SEATBELT WAS ON AND WORN PROPERLY. HER BODY WAS THROWN FORWARD THEN SLAMMED BACK HARD. SHE SUSTAINED INJURY AND WAS DIAGNOSED WITH A BRAIN CONTUSION AND SEVERE WHIPLASH BY THE TRAUMA UNIT AFTER BEING RUSHED VIA AMBULANCE TO THE NEAREST LOCAL HOSPITAL. *TR
