Abstract

A vehicle seat including: a seat pad made of foamed resin; and a seat cover being integral with the seat pad, wherein a seating surface of the seat pad includes a seating part and a bank part, wherein a portion of the seat cover covering a seat inner side portion of the bank part includes a seat cover main part and a planar reinforcing member arranged on a back side of the seat cover main part, wherein the reinforcing member is configured by a material bendable and deformable towards a seat pad side and includes a general section and a flexible section which can be more easily bent towards the seat pad side than the general section, and wherein a portion of the reinforcing member covering a peak side of the bank part is configured by the flexible section.

Claims

1. A vehicle seat comprising:

a seat pad made of foamed resin; and

a seat cover covering the seat pad and being integral with the seat pad,

wherein a seating surface of the seat pad includes a seating part forming a middle of the seating surface in a seat width direction and a bank part located at a lateral side of the seating part in the seat width direction and protruding to a seating side,

wherein a portion of the seat cover covering a seat inner side portion of the bank part includes a seat cover main part configuring a design surface of the seat and a planar reinforcing member arranged on a back side of the seat cover main part which faces the seat pad,

wherein the reinforcing member is configured by a material bendable and deformable towards a seat pad side and includes a general section and a flexible section which can be more easily bent towards the seat pad side than the general section, and

wherein a portion of the reinforcing member covering a peak side of the bank part is configured by the flexible section.

2. The vehicle seat according to claim 1,

wherein the flexible section includes a restriction part configured to restrict entry of resin forming the seat pad.

3. The vehicle seat according to claim 1, further comprising:

a restriction part which is configured to restrict entry of resin forming the seat pad and is configured by a member different from the flexible section.

4. The vehicle seat according to claim 3,

wherein the general section includes an impregnated part into which the resin forming the seat pad is entered and solidified, and

wherein the restriction part includes a low impregnated part into which a smaller amount of the resin is entered and solidified as compared with the impregnated part.

5. The vehicle seat according to claim 1,

wherein the flexible section is made easier to be bent towards the seat pad side than the general section by adjusting an amount of material consisting the reinforcing member to be smaller in the flexible section than that in the general section.

6. The vehicle seat according to claim 1,

wherein a thickness of the flexible section in a thickness direction of the reinforcing member is smaller than a thickness of the general section in the thickness direction of the reinforcing member.
