A reinforcing structure for a seat back frame (10) is provided with a panel member (20) and a frame member (30) joined to the panel member (20), the panel member (20) has an outer peripheral flange (25) formed by bending the outer peripheral edge of the panel member (20), and a plurality of outer peripheral ribs (26,...) disposed at intervals in the circumferential direction of the panel member (20) are formed on the outer peripheral flange (25). Thus, both the outer peripheral flange (25) and the plurality of outer peripheral stiffeners (26) can improve the rigidity of the outer peripheral edge of the panel member (20) in a multiplied manner, and the rigidity of the seat back frame (10) can be improved.
一种座椅靠背框架(10)的加强构造,具备面板件(20)、相对于该面板件(20)接合的框架件(30),面板件(20)具有该面板件(20)的外周缘部被弯折而形成的外周凸缘(25),在外周凸缘(25)上形成有沿面板件(20)的周向隔开间隔而配置的多个外周加强筋(26)…。从而,通过外周凸缘(25)和多个外周加强筋(26)的双方能够成倍地提高面板件(20)的外周缘部的刚性,进而能够使座椅靠背框架(10)的刚性提高。
