Abstract

An air bag-containing cover comprises: a surface skin layer made of a thermoplastic polymer containing 40-80 weight % ingredient A: a hydrogenated derivative of a block copolymer comprising styrene and conjugated diene, 5 to 30 weight % ingredient B: an olefinic resin, 2 to 30 weight % ingredient C: polyisobutylene with a viscosity average molecular weight of not greater than 70,000, and 0 to 20 weight % ingredient D: a hydrocarbon series rubber softening agent with a kinetic viscosity at 40 DEG C of not greater than 500 cSt and/or polybutene with a number average molecular weight of not greater than 2500, in which the thermoplastic polymer has a JIS-A hardness according to JIS-K6301 of from 20 to 90, and a core layer comprising an olefinic resin having a modulus in flexure according to JIS-K7203 of from 1000 to 700 kg/cm<2>, in which the core layer has a higher hardness than that of the surface skinlayer, and the core layer has a portion (1c) for easily bursting the cover upon initiation of the air bag operation.
