Abstract: There is provided a seatback frame including: left and right side frames that are provided at left and right side portions of a seatback of a vehicle seat, with the respective lower end portions of the side frames coupled to a rear end portion of a seat cushion frame provided to a seat cushion of the vehicle seat; and a back face panel that is formed of sheet metal, that spans across between rear end portions of lower portions of the left and right side frames with its thickness direction along a seatback front-rear direction, that is fixed to the left and right side frames, and that includes an undulating shaped portion bent such that peaks and troughs alternate in a row along a seat width direction.

Abstract: In a vehicle seat, beads are formed to a SC panel, and the beads extend along the seat front-rear direction adjacent to joint portions at seat width direction insides of the joint portions. When repeated load in the seat up-down direction is input to a seat width direction intermediate portion of the SC panel, for example, the SC panel is displaced by the input load in the seat up-down direction, and tensile load in the seat width direction acts on the beads as a result. The beads extend or contract in the seat width direction due to the tensile load. Load input to the SC panel is thereby absorbed by the extension and contraction of the beads, and load in the seat up-down direction input to the joint portions is reduced. This enables concentration of stress at the joint portions to be suppressed.

Abstract translation: 在车辆座椅中，珠形成为SC面板，并且珠沿着座椅前后方向在接合部的座宽度方向内侧与接合部相邻地延伸。 当将座椅上下方向的重复载荷输入到SC面板的座椅宽度方向中间部分时，例如，SC面板在座椅上下方向上被输入负载移位，并且座椅中的拉伸载荷 结果，宽度方向作用在珠上。 由于拉伸载荷，珠沿座椅宽度方向延伸或收缩。 因此，通过珠的伸缩收缩对SC面板的负荷输入，从而减少了输入到接合部的座椅上下方向的负荷。 由此，能够抑制接合部的应力集中。

Abstract: In a vehicle seat (10), beads (42) are formed to a SC panel (30), and the beads (42) extend along the seat front-rear direction adjacent to joint portions (40) at seat width direction insides of the joint portions (40). When repeated load in the seat up-down direction is input to a seat width direction intermediate portion of the SC panel (30), for example, the SC panel (30) is displaced by the input load in the seat up-down direction, and tensile load in the seat width direction acts on the beads (42) as a result. The beads (42) extend or contract in the seat width direction due to the tensile load. Load input to the SC panel (30) is thereby absorbed by the extension and contraction of the beads (42), and load in the seat up-down direction input to the joint portions (40) is reduced. This enables concentration of stress at the joint portions (40) to be suppressed.
