An automobile weatherstripping includes an extrusion-formed part and a mold-formed part, the mold-formed part being welded and integrated with the extrusion-formed part. The extrusion-formed part is made of an olefin elastomer and the mold-formed part is made of a resin composition containing an olefin resin, ethylene-&agr;-olefin copolymer rubber, hydrogenated aromatic vinyl conjugated diene compounds block copolymer mineral oil and at least one of natural rubber and butadiene rubber in predetermined proportions. The extrusion-formed part and the mold-formed part have a sufficient level of bonding strength with no bonding agent layer being used therebetween.

Disclosed is a casing for storing an airbag for an airbag restraint system, cavingg: a main body formed of a material comprising a thermoplastic elastomer composition which is prepared by: mixing 100 parts by weight of a copolymer composition with 0.05 to 0.5 parts by weight of a lubricant comprising higher fatty acid amide to obtain a mixture; and dynamically heat-treating the mixture in the presence of an organic peroxide and an auxiliary crosslinking agent. The copolymer composition contains: (A) 20 to 50 parts by weight of an olefin copolymer resin of propylene and one or two kinds of 1-olefin other than propylene; (B) 10 to 50 parts by weight of ethylene-propylene copolymer rubber having a Mooney viscosity (ML,, 100&deg; C.) ranging from 30 to 60; (C) 10 to 70 parts by weight of ethylene-propylene-nonconjugated diene copolymer rubber having a Mooney viscosity (ML,, 100&deg; C.) ranging from 50 to 100; and (D) 10 to 50 parts by weight of an oil-extended ethylene-propylene-nonconjugated diene copolymer rubber containing ethylene-propylene-nonconjugated diene copolymer having a Mooney viscosity (ML,, 100&deg; C.) ranging from 150 to 350 and a mineral oil softener contained at an amount of 50 to 150 parts by weight relative to 100 parts by weight of the ethylene-propylene-nonconjugated diene copolymer.

Airbag storing casing

An automobile weather strip including at least (a) a weather strip body formed from a first composition including at least one rubber polymer and at least one chemical suitable for effecting sulfur-vulcanization, and (b) a decorative layer formed from a second composition including at least one thermoplastic elastomer and hydrotalcite as a discoloration-preventing agent for the decorative layer. The decorative layer is directly adhered onto the weather strip body.

An air bag cover for a passenger of an automobile, obtained by molding a thermoplastic elastomer composition which comprises an olefin-based resin (A) and an ethylene-.alpha.-olefin-based copolymer rubber (B), and provides a 2 mm thick molded body composed of the composition having a linear thermal expansion coefficient at a temperature of -40 to 120.degree. C. of 13.5.times.10.sup.-5 mm/m.degree.C. or less, a fracture elongation at weld part of 50% or more, and an Izod impact strength at a temperature of -50.degree. C. or more of 35 kg.multidot.cm/cm or more, or revealing Non Break. According to the present invention, there can be provided an air bag cover for a passenger side seat of an automobile, which does not cause building up or separation from surrounding parts when installed and set into a dash board of the automobile, and has excellent safety in spreading.
