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.

摘要： A seat cushion includes a seat cushion base layer which biases two base support parts in directions approaching each other, and has base support part elastic members which are elastically deformed in an up-down direction, thereby causing the seat cushion to have a configuration having a high spring characteristic. In the seat cushion and the seat back, the seat cushion is configured to be set to be larger than the seat back regarding a range of connecting an origin, a maximum displacement point, and a maximum load point, and a ratio of an area of a range including an inward curve to an area of a range including an outward curve in a predetermined load-deflection characteristic.

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. 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 is influenced by foaming heat generated at the time of the foaming of the polyurethane foam raw material in a mold, 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 with a polyurethane foam layer in the mold by integrated foaming, and therefore, there is no need to work the integration target to a state closer to a final shape in a step before it is disposed in the mold, which can simplify manufacturing steps and reduce manufacturing cost.
