摘要:
To obtain an integrated foam-molded product whose manufacturing cost is reduced and which makes an effective use of a property of an integration target (10). Foaming heat generated at the time of the foaming of a polyurethane foam raw material, whose influence has been conventionally prevented by contriving a special measure, is positively used. The integration target (10) is influenced by foaming heat generated at the time of the foaming of the polyurethane foam raw material in a mold (40), to thermally deform into a desired shape along a mold shape. Consequently, it is possible to mold the integration target into an arbitrary shape in a step of integrating the integration target (10) with a polyurethane foam layer (30) in the mold (40) by integrated foaming, and therefore, there is no need to work the integration target (10) to a state closer to a final shape in a step before it is disposed in the mold (40), which can simplify manufacturing steps and reduce manufacturing cost.

摘要:
To provide a seat having a high cushioning property, excellent in a drainage property, and suitable for outdoor use. A belt-shaped support member 30 for seat back is supported on an upper portion of a seat back frame 10, a belt-shaped support member 40 for seat cushion having end portions 42, 43 connected to a front portion of a seat cushion frame 20 is connected to a lower portion of the belt-shaped support member 30 for seat back, and a base support member 50 is disposed on a seat cushion. A surface cushion layer 60 with which a cushioning part for seat back and a cushioning part for seat cushion are integrally formed is disposed by being supported on the upper portion of the seat back frame 10 and the front portion of the seat cushion frame 20. The end portions 42, 43 of the belt-shaped support member 40 for seat cushion connected to the front portion of the seat cushion frame 20 work as a fulcrum for supporting a portion from the waist to the vicinity of the pelvis of a seated person, and an upper portion of the surface cushion layer 60 supported on the upper portion of the seat back frame 10 works as a fulcrum for supporting a portion from the femoral region to the vicinity of the hip of the seated person.
