ABSTRACT:
A casing for storing an airbag of an airbag restraint system for an automobile vehicle. The casing is formed of a material comprising (a) a thermoplastic elastomer composition in an amount of 100 parts by weight, the thermoplastic elastomer composition being prepared by a process including mixing 10 to 50 parts by weight of a polyolefine resin with 100 parts by weight of an olefine copolymer rubber to obtain a mixture, dynamically heat-treating the mixture in the presence of an organic peroxide, and then adding 5 to 50 parts by weight of a mineral oil relative to 100 parts by weight of the dynamically heat-treated mixture, the olefine copolymer rubber having a Mooney viscosity (ML.sub.1+4, 100.degree. C.) ranging from 50 to 100; (b) a random copolymer resin in an amount of 20 to 50 parts by weight, containing propylene and at least one kind of 1-olefine other than propylene and having a Melt Flow Rate (230.degree. C.) ranging from 30 to 100; and (c) a modified polypropylene oligomer containing hydroxyl group, in an amount ranging from 1 to 5 parts by weight.
