2010 Nissan Altima Seats Problems

I WAS IN AN ACCIDENT WHERE I WAS HIT AT HIGHWAY SPEED AND MY CAR SPUN OUT OF CONTROL. THE CAR WAS TRAVELING BACKWARDS WHEN IT WENT OFF THE SIDE OF THE HIGHWAY AND INTO A DITCH. WHEN THE REAR OF THE CAR ENTERED THE DITCH THE IMPACT WAS SIGNIFICANT AND MY DRIVER SIDE SEAT BACK WENT ALL THE WAY BACK. I FEEL THAT THIS IS A SIGNIFICANT DEFECT, BECAUSE THE SEAT BACK AND SEAT BELT SHOULD KEEP THE DRIVER AND PASSENGERS AS STILL AS POSSIBLE. I DON'T BELIEVE THAT THE SEAT BACK COLLAPSING BACKWARDS IS INTENDED BY THE DESIGN. WHEN I WENT TO VIEW THE CAR AND RETRIEVE MY PERSONAL BELONGINGS, I TRIED TO BRING THE SEAT BACK TO THE UPRIGHT POSITION, BUT THE LEVER WAS BENT AND WAS NOT ABLE TO BE LIFTED IN ORDER TO BRING THE SEAT BACK UP. I TOOK PICTURES OF THE BENT LEVER AND THE POSITION OF THE SEAT.
