I WAS IN A NISSAN ALTIMA WITH THREE PASSENGERS, TWO IN THE BACK SEATS AND ONE IN THE FRONT SEAT. WHEN IN THE PROCESS OF TURNING LEFT SOMEONE CRASHED INTO THE REAR OF MY VEHICLE. BOTH THE FRONT SEATS BROKE AT THE HINGE PUSHING THE SEATS BACK INTO THE BACKSEAT PASSENGERS. THIS RESULTED IN MINOR INJURIES TO THEM; SCRAPS ON LEG AND HEAD, BLOODY NOSE AND BRUISED TEETH. IF THE SEATS HAD NOT FAILED, THESE MINOR INJURIES WOULD NOT HAVE OCCURED. IT IS ALSO UNCLEAR HOW NECK ISSUES ON THE DRIVER AND PASSENGERS WERE EXACERBATED. MY VEHICLE WAS MOVING SLOW AND WAS NOT YET AT A FULL STOP. IT WAS ON A RURAL TWO LANE ROAD. THE SPEED LIMIT WAS 50 MPH.*DT
