Abstract

Provided is a conveyance seat with which the assemblability of a wire member with respect to a seat frame can be improved. A conveyance seat includes a seat frame. The seat frame has: a pair of side frames arranged in side portions of the conveyance seat; and a cross-linking frame cross-linking the pair of side frames, a wire member is disposed between the pair of side frames, the cross-linking frame has a wire receiving portion receiving the wire member, and the wire member is fastened to the wire receiving portion.

First claim

The invention claimed is:

1. A conveyance seat comprising a seat frame, wherein
the seat frame includes:
a pair of side frames arranged in side portions of the conveyance seat; and
a cross-linking frame cross-linking the pair of side frames,

a wire member is disposed between the pair of side frames,
the cross-linking frame has a wire receiving portion receiving the wire member,
the wire receiving portion is a recessed portion recessed from an inside toward an outside in a width direction of the conveyance seat,
the wire member is urged toward the outside in the width direction of the conveyance seat and fastened to the recessed portion of the wire receiving portion in the width direction of the conveyance seat, and
the cross-linking frame further includes an end portion receiving portion receiving an end portion of the wire member, wherein the end portion receiving portion is a separate portion from the wire receiving portion.

2. The conveyance seat according to claim 1 , wherein the end portion of the wire member in the width direction of the conveyance seat is bent outward and is inserted through the end portion receiving portion.

3. The conveyance seat according to claim 1 , wherein the wire receiving portion has a first part close to an occupant support surface and a second part far from the occupant support surface, and
the first part is formed shorter than the second part in the width direction of the conveyance seat.

4. The conveyance seat according to claim 1 , wherein the wire receiving portion is formed so as to be curved in a direction toward an occupant support surface.

5. The conveyance seat according to claim 1 , wherein a planar pressure receiving member is attached to the wire member.

6. The conveyance seat according to claim 5 , wherein the wire member is disposed so as to be separated in the width direction of the conveyance seat, and
a distance between the wire members disposed so as to be separated in the width direction of the conveyance seat increases toward the cross-linking frame.

7. The conveyance seat according to claim 6 , wherein the pressure receiving member is provided with an engaging portion for fixing to the wire member on a side opposite to an occupant support surface, and
the engaging portion is provided with an inclined portion inclined outward in the width direction of the conveyance seat.

8. A method for manufacturing a conveyance seat, comprising:
a step of preparing a wire member;
a step of preparing a seat frame having a pair of side frames arranged in side portions of the conveyance seat and a cross-linking frame cross-linking the pair of side frames, wherein the cross-linking frame has a wire receiving portion receiving the wire member, wherein the wire receiving portion is a recessed portion recessed from an inside toward an outside in a width direction of the conveyance seat, wherein the cross-linking frame further includes an end portion receiving portion receiving an end portion of the wire member, wherein the end portion receiving portion is a separate portion from the wire receiving portion;
a step of fastening the wire member that is urged toward the outside in the width direction of the conveyance seat to the recessed portion of the wire receiving portion of the cross-linking frame;
a step of inserting the end portion of the wire member through the end portion receiving portion; and
a step of attaching a skin material and a pad member to the seat frame.

9. The conveyance seat manufacturing method according to claim 8 , wherein the step of fastening the wire member includes moving the wire member from the inside to the outside in the width direction of the conveyance seat to fasten the wire member to the wire receiving portion.
