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 (10) is provided with a pair of left and right forming wires (11) erected on a seat cushion frame in the front and back direction, and a resin part (12) combined with the forming wires (11). Each of the molding lines (11) has a central line (11A) and a side line (11B) which are arranged left and right and extend front and back. The resin member (12) has a rear connection portion (12C) and a pair of deflection restricting portions (12A). The rear connection section (12C) extends in a region rearward of the ischium support section so as to connect the side lines (11B) and the center lines (11A) and the center lines (11A) in the left-right direction. Each deflection restricting section (12A) extends from the rear connecting section (12C) so as to connect all crank sections (B1), which are formed on each side line (11B) and bent so as to repeatedly fold back left and right, in the front-back direction.
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(10)具有前后架设于座椅座垫框架的左右一对成形线(11)和与它们结合的树脂部件(12)。各成形线(11)具有相互左右排列且前后延伸的中央线(11A)和侧线(11B)。树脂部件(12)具有后连接部(12C)和一对挠曲限制部(12A)。后连接部(12C)在比坐骨支撑部靠后侧的区域以将各侧线(11B)与中央线(11A)之间及各中央线(11A)之间分别在左右方向上连接的方式延伸。各挠曲限制部(12A)从后连接部(12C)以将形成于各侧线(11B)的左右反复折回地弯曲的全部曲柄部(B1)之间前后连接的方式延伸。
