To provide a seat having a high cushioning property, excellent in a drainage property, and suitable for outdoor use. A belt-shaped support memberfor seat back is supported on an upper portion of a seat back frame, a belt-shaped support memberfor seat cushion having end portionsconnected to a front portion of a seat cushion frameis connected to a lower portion of the belt-shaped support memberfor seat back, and a base support memberis disposed on a seat cushion. A surface cushion layerwith 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 frameand the front portion of the seat cushion frame. The end portionsof the belt-shaped support memberfor seat cushion connected to the front portion of the seat cushion framework 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 layersupported on the upper portion of the seat back frameworks as a fulcrum for supporting a portion from the femoral region to the vicinity of the hip of the seated person.

Seat

To achieve weight reduction while providing elasticity sufficient in a cushioning member for a vehicle seat, an elastic member made of expanded resin beads includes an elastic covering material having stretching properties stuck to an outer face of an expanded bead body. Therefore, when the elastic member made of expanded resin beads is bent or compressed, the respective beads themselves configuring the expanded bead body are elastically deformed according to stretching or compressing of the elastic covering material, and since the elastic deformation is not such deformation that a gap between beads of the expanded bead body largely expands, a crack occurring between beads or permanent deformation does not occur so that bending or compressing becomes possible. Accordingly, the elastic member made of expanded resin beads is suitable as a cushioning member utilizing an elastic recovering force in a bending direction and a thickness direction thereof.
