A support member provided to the vehicle seat supports the seated occupant from a side of the seated occupant, and includes an inner plate attached to a seat width direction inner side of a side frame, an outer plate attached to a seat width direction outer side of the side frame, and a connection plate for connecting the inner plate and the outer plate on a seat front side. The outer plate is attached to the seat width direction outer side of the side frame at a position that does not overlap in the seat width direction with attachment positions of the inner plate and the side frame.

First claim

What is claimed is:

1. A vehicle seat comprising:
a support portion that is attached to a side frame of a seat frame and supports a seated occupant from a side of the seated occupant;
wherein the support portion comprises a projection that has a thickness smaller than a distance between end portions of the support portion in an up and down direction and that contacts a front surface of the side frame,
the projection comprises a plurality of projecting portions, and
the plurality of projecting portions is individually arranged at different positions in height.

2. The vehicle seat according to claim 1 , wherein a space is provided between the side frame and the projection.

3. The vehicle seat according to claim 1 , further comprising an attachment portion configured to attach the support portion to the side frame,
wherein a projecting portion that is arranged at the uppermost position among the plurality of projecting portions is located above the attachment portion.

4. The vehicle seat according to claim 1 , wherein
an upper portion of the side frame is formed by a member of which an outer surface is a curved surface, and a lower portion of the side frame is formed by a plate member, and
the projection of the support portion is arranged to face the plate member of the side frame.

5. The vehicle seat according to claim 1 , further comprising an attachment portion configured to attach the support portion to the side frame,
wherein a rear end portion of the projection is located in front of the attachment portion.

6. The vehicle seat according to claim 1 , wherein a rear end of the support portion is not provided with the projection.

7. The vehicle seat according to claim 1 , further comprising an attachment portion configured to attach the support portion to the side frame, wherein
the attachment portion is a screw that is inserted into the side frame, and
a projection amount of the projection is larger than a projection amount of a projecting part of the screw that projects from an outlet of a screw hole provided in the side frame.

8. The vehicle seat according to claim 1 , wherein the support portion covers an outside surface of the side frame from outside.

9. The vehicle seat according to claim 1 , further comprising an attachment portion configured to attach the support portion to the side frame, wherein
at least a part of the projection is located at an outer side of the attachment portion in a seat width direction.

10. The vehicle seat according to claim 1 , wherein the projection extends in a seat width direction.

11. The vehicle seat according to claim 1 , wherein the projection extends in a seat front to back direction.

12. A method for manufacturing a vehicle seat that has a support portion attached to a side frame of a seat frame of the vehicle seat for supporting a seated occupant from a side of the seated occupant, wherein the support portion includes a projection that has a thickness smaller than a distance between end portions of the support portion in an up and down direction, the method comprising:
arranging the support portion so that the projection of the support portion contacts a front surface of the side frame, and
attaching the support portion to the side frame,
wherein the projection comprises a plurality of projecting portions, and
the plurality of projecting portions is individually arranged at different positions in height.

13. The method according to claim 12 , wherein a space is provided between the side frame and the projection.

14. The method according to claim 12 , wherein the vehicle seat further comprises an attachment portion configured to attach the support portion to the side frame,
wherein a projecting portion that is arranged at the uppermost position among the plurality of projecting portions is located above the attachment portion.

15. The method according to claim 12 , wherein
an upper portion of the side frame is formed by a member of which an outer surface is a curved surface, and a lower portion of the side frame is formed by a plate member, and
the projection of the support portion is arranged to face the plate member of the side frame.

16. The vehicle seat according to claim 1 ,
wherein
the support portion comprises a first wall and a second wall that are provided next to each other, and a connecting portion that connects the first wall and the second wall, and
