A seat frame includes a lower frame configured to couple lower portions of side frames arranged on right and left sides. The lower frame includes a back wall portion provided on a back side, a front wall portion provided in front of the back wall portion, and a coupling portion that couples lower ends of the back wall portion and the front wall portion. The back wall portion includes a pair of side portions forming ends in a seat width direction and each formed along the outer shapes of the side frames, and an inclined portion provided between the side portions and inclined such that a lower end is positioned in front of an upper end. The inclined portion is provided in front of the side portions.

Abstract: Provided is a conveyance seat configured for adjustment of a deflection amount of a seat forming the conveyance seat, i.e., cushion properties of the seat. The conveyance seat includes a seat frame and a buffering body bridged over the seat frame configured to elastically support a seated occupant. The buffering body has a wire having both end portions attached to the seat frame, and a back restriction member configured to support at least a portion of the wire to restrict deflection of the portion of the wire. The wire includes a first right-to-left extending portion and a second right-to-left extending portion that extend in a seat right-to-left direction, and a coupling portion coupling the first right-to-left extending portion and the second right-to-left extending portion. The back restriction member is made of a resin material, and supports the first right-to-left extending portion and the second right-to-left extending portion.
