  • Patent number: 8142869
    Abstract: The present invention provides a coated base fabric for airbags including: a cloth obtained by weaving polyamide (PA) fiber yarns; and a PA elastomer coating film formed on one surface or both surfaces of the cloth, wherein the coated base fabric has predetermined air tightness and flexibility, is easily converted to a PA reproduced material, and is obtained by fusing a coating film (16) made of an airflow suppression PA elastomer on one surface or both surfaces of a cloth (14) obtained by weaving yarns (12) and (12A) made of a polyamide (PA) fiber, as the PA elastomer, soft PA is normally used, which has a melting point (measured by the standard of ASTM D3418) of 135 to 200° C., a difference between the melting points of the PA fiber and PA elastomer being 80 to 120° C.

  • Patent number: 6680490
    Abstract: After a light-emitting element exhibiting an emission peak wavelength in a wavelength range of not longer than 500 nm is mounted into a cup-like portion of a base member, the cup-like portion is filled with epoxy group-containing silicone rubber. An aromatic polyamide-based resin is used as a reflector material.

  • Patent number: 5376461
    Abstract: A pad of air bag apparatus which, as a molded part, has an enhanced soft touch and which is protected against accelerated time-dependent changes in the physical properties of the pad's core and skin layers, wherein the pad covers the upper surface of an air bag apparatus which is to be mounted on the steering wheel of an automobile or in any other necessary areas. The pad includes of a skin layer formed of a soft first resin material and a core layer formed of a second resin material harder than the first resin material. The first resin material is a styrenic thermoplastic elastomer (TPE) or olefinic TPE having a hardness (JIS A) of 70 and less whereas the second resin material is a polyester based TPE having a flexural modulus of 1,000-4,000 kgf/cm.sup.2 (98-392 MPa) or a polyurethane based TPE having a flexural modulus of 1,000-2,500 kgf/cm.sup.2 (98-245 MPa).
