Title: Cushioning material
Inventor: ONO KOTARO
IPC: B32B3/28
Filed: 2000-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a planar cushioning material good in air permeability, utilizing the elasticity of a resin wire material and/or a resin cylindrical material. SOLUTION: Curved parts having elasticity comprising a resin wire material and/or the resin cylindrical material are allowed to be present between two sheets to be fixed to both sheets or integrally molded along with both sheets. For example, the resin wire materials 2, 5 are heated and deformed by a heating roll having a tooth mold provided on the peripheral surface thereof to be sent into the gap between the sheets 3 and integrally bonded to the sheets 3 to obtain a cushioning material 1. The resin cylindrical material is used as it is by utilizing the elasticity in the radial direction thereof or cut in round slices to be used in a ring shape. Or, a press mold and a receiving mold are pressed to a thermoplastic resin sheet to project curved tapes and these tapes are integrally molded along with the sheets.  This cushioning material is suitable as a cushioning material for a seat because it is high in air permeability and can send hot air and cold air to enable air conditioning.
