Don't be surprised to find it cracked somewhere, they use thin metal now to lower the weight and It's often HSS steel which will crack at welds if it gets flexed enough. Ford cars have utter fits with them.
Although bent is possible, not likely as that usually simply changes angles of fitment, true loose says something may be broken there.
On Fords I've fixed them by stripping the parts and using metal plates to patch the crack and brazing to suit. It takes much patience to remove the seat liner and underlayment without ruining them, not meant to happen.
On the Fords it happens on seat backs because when they fold they only make the pivot on one side instead of both (?????), meaning all load on one side goes through a tube to the other side to have both pivot at one point. And the side unsupported is the one that you lean against as you get into the cars to then pressure all that undue leverage created by incompetent design into the pivot point again, they break at welds around it from the too high a load. Another case of planning parts that fault early due to using the engineers for that instead of making the cars last longer. What idiot has a seat fold to only fold on one side???
