Abstract
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.
