Abstract

A method for manufacturing a vehicle seat component includes a first step of integrating a cushion member and an upholstery member together during molding of the cushion member, and a second step of forming a flow passage through which air passes from a back surface of the cushion member toward the upholstery member.

Claims

1. A method for manufacturing a vehicle seat component that includes a cushion member and an upholstery member that covers the cushion member, the cushion member and the upholstery member being integrated together, comprising:

a first step of integrating the cushion member and the upholstery member together during molding of the cushion member; and

a second step of forming a flow passage through which air passes from a back surface of the cushion member toward the upholstery member.

2. The method for manufacturing the vehicle seat component according to claim 1, wherein:

a thin section that is recessed toward the upholstery member is formed in the back surface of the cushion member in the first step.

3. The method for manufacturing the vehicle seat component according to claim 2, wherein:

the upholstery member has a first portion that is air-permeable and arranged at a seating side of the upholstery member, and a second portion that is laminated on the first portion and that prevents intrusion of a molding material of the cushion member; and

the flow passage that passes through the thin section and the second portion is formed in the second step.

4. The method for manufacturing the vehicle seat component according to claim 3, wherein, in the first step, the upholstery member is integrated with a surface of the cushion member and a backing member is arranged on the back surface of the cushion member at portions other than a portion at which the thin section is formed.
