A seat, particularly an air passenger seat, includes a seat part and a backrest. The backrest has a backrest element ( 10 ) with an arched, one-piece frame part ( 12 ) having at least one hollow profile ( 14 ). In order for the frame part ( 12 ) to have, at least in part, at least one additional hollow profile ( 16 ) and for the adjoining hollow profiles ( 14, 16 ) to be situated one behind the other in the normal direction of movement (flying direction ( 18 )) of the seat, the backrest element is reinforced in the relevant areas in such a manner that, even in the event of a crash, the base frame structure remains intact. |
