The invention provides a seat cushion spring capable of appropriately improving roll rigidity of a side portion of a seat cushion. The seat cushion spring is provided with a molding line erected on the seat cushion frame in the front-back direction of the seat and a resin part combined with the molding line. The molding line is composed of a single line having a center line and a side line which are aligned with each other in the seat width direction and which extend in the seat front-rear direction such that one end of each of the center line and the side line is connected to each other. The center line and the side lines each have a plurality of crank sections bent so as to be alternately folded back in a crank shape in one side and the other side in the seat width direction. The resin member has a deflection restricting portion that connects the plurality of crank portions so as to restrict opening in the seat front-rear direction between three or more continuously arranged crank portions formed in the front-rear direction of the side line.

    本发明提供一种座垫弹簧,能够适当地提高座椅座垫的侧部的侧倾刚性。座垫弹簧具有在座椅前后方向上架设于座椅座垫框架的成形线和与成形线结合的树脂部件。成形线由一根线构成,该一根线具有互相在座椅宽度方向上排列且以各自的一端彼此连接的方式在座椅前后方向上延伸的中央线和侧线。中央线和侧线分别具有以在座椅宽度方向的一方和另一方交替地折回成曲柄状的方式弯曲的多个曲柄部。树脂部件具有挠曲限制部,该挠曲限制部将多个曲柄部之间连接,以限制形成于侧线的前后三个以上的连续排列的曲柄部之间在座椅前后方向上打开。
