PROBLEM TO BE SOLVED: To provide a seat frame that is made of a resin material and can secure high rigidity.SOLUTION: A seat frame F made of resin constitutes a frame of a vehicle seat S for an occupant to be seated and is formed in a hollow closed cross section shape. A material constituting at least part of the seat frame F is a laminated resin material M having a plurality of resin materials laminated, and a resin material constituting layers of the laminated resin materials is carbon fiber resin. The resin material is comprised of unidirectional materials M2 having carbon fibers arrayed to run along one direction and cloth materials M1 having carbon fibers knitted in a lattice shape. The laminated resin material M is arranged so that the plurality of the cloth materials M1 or the plurality of unidirectional materials M2 are symmetric in fiber orientation to the center of a laminate relative to either one, as the center of the laminate, of the cloth materials M1 or the unidirectional materials M2 so as to form a layer to hold the center of the laminate.

    【課題】樹脂材料からなり、高い剛性を確保することが可能なシートフレームを提供することにある。【解決手段】乗員が着座する車両用シートSの骨格を構成し、中空閉断面形状に形成された樹脂製のシートフレームFに関する。シートフレームFの少なくとも一部を構成する素材は、複数の樹脂素材が積層された積層樹脂素材Mであり、積層樹脂素材の層を構成する樹脂素材は、炭素繊維樹脂である。この樹脂素材は、炭素繊維が一方向に沿って走るように整列した一方向材M2と、炭素繊維が格子状に編まれたクロス材M1と、を有して構成されており、積層樹脂素材Mは、クロス材M1若しくは一方向材M2のうち積層中心となる一つの素材に対し、複数のクロス材M1若しくは複数の一方向材M2が積層中心に対して繊維配向対称となるよう配置されて積層中心を挟持するように層を成している。【選択図】図6
