Abstract
An osmosis membrane is disposed at the boundary between a three-dimensional network structure section and a foam section. The osmosis membrane allows a liquid foam material to permeate. The three-dimensional network structure section is impregnated with the foam material through the osmosis membrane, and subsequently the foam material is solidified, thereby connecting the three-dimensional network structure section and the foam section to each other. The bonded body of the three-dimensional network structure section and the foam section is completed only by disposing the cushion structure component in between the upper mold and the lower mold, and performing a foaming step.
Claims13
A cushion structure, comprising:
- a three-dimensional network structure section formed by causing resin wires having elasticity to adhere to each other at adhesion points, the wires being curved and entangled with each other;
- a foam section that is disposed to surround side surfaces of the three-dimensional network structure section, and is formed by foaming and solidifying a liquid foam material;
- and
- an osmosis membrane disposed at a boundary between the three-dimensional network structure section and the foam section,
- wherein the osmosis membrane allows the liquid foam material to permeate, and the three-dimensional network structure section is impregnated with the liquid foam material through the osmosis membrane, and subsequently the foam material is solidified to connect the three-dimensional network structure section and the foam section to each other.

- and
- a foam section that is disposed to surround side surfaces of the three-dimensional network structure section, and is formed by foaming and solidifying a liquid foam material;
- and
- an impregnation prevention membrane disposed in the three-dimensional network structure section,
- wherein the impregnation prevention membrane makes the liquid foam material impermeable, and a site of the three-dimensional network structure section that is not made impermeable by the impregnation prevention membrane is impregnated with the foam material, and subsequently the foam material is solidified to form an impregnated section in the three-dimensional network structure section and connect the three-dimensional network structure section and the foam section to each other.
