  • Patent number: 7479313
    Abstract: Systems and methods consistent with the present invention provide a thermoplastic resin-laminated structure having an exterior layer, a base layer, and a binding layer that is placed between the exterior layer and the base layer. The exterior, base and binding layers include at least one material selected from a group consisting of electric resistance-heat generating materials and heat-conductive materials, and has at least one connection terminal at a certain region for supplying at least one of electricity or heat. The resin-laminated structure has excellent properties such as adhesive strength between a base layer and an exterior layer, and recycling utility as well as surface quality in feeling, thermal durability, acoustic absorptivity, heat-shielding property, and impulse-durability.
