SEAT BACK FRAME STRUCTURE

摘要

PROBLEM TO BE SOLVED: To surely reduce the weight of a side bracket without lowering the stiffening performance of the side bracket. SOLUTION: The lower part of a side frame 14 is separately formed from a side frame body 14-1 above the lower part of the frame 14 in such a manner that the lower part of the frame is formed, as a mount bracket 14-2, so as to have a thickness equal to or larger than that of the side frame body 14. The top edge 16 of the side surface base part 14-2a of the bracket 14-2 is formed into a forwardly inclined edge. Since the body 14-1 is adhered to the bracket 14-2 in a joint regionαalong the top edge, the side frame 14 is integrally formed.
