  • Patent number: 10893750
    Abstract: A method for producing a seat core material that has a foamed molded substrate and a frame member embedded in a periphery thereof, which includes, as step (a), heating thermoplastic resin expanded beads in a mold cavity, in which the frame member has been disposed, to fusion-bond the expanded beads to each other and to obtain the foamed molded substrate with the frame member being embedded in the periphery thereof; and, as step (b), simultaneously with step (a) or after step (a), forming a void cavity S, S? in the foamed molded substrate at a position along and adjacent to the frame member. The void cavity S, S? has a size and shape that allows a relative displacement between the frame member and the foamed molded substrate when the foamed molded substrate shrinks after step (b).
