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.
Claims20
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;
- 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,
- wherein the three-dimensional network structure section and the foam section are connected to each other by impregnating the three-dimensional network structure section with the liquid than material and subsequently solidifying the foam material.
A cushion structure component, 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;
- and
- an osmosis membrane which is disposed to surround side surfaces of the three-dimensional network structure section and through which a liquid foam material to be formed into foam by foaming and being solidified is permeable.
A cushion structure component, 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;
- and
- an impregnation prevention membrane which is disposed in the three-dimensional network structure section and where a liquid foam material to be formed into foam by foaming and being solidified is impermeable.
