Hybrid inflator with crystalline and amorphous block copolymer |
摘要 |
A hybrid inflator for an inflatable vehicle occupant protection device comprises a quantity of a stored inflation fluid (42) and a body (44) of an ignitable combustible material to heat the stored inflation fluid and increase its pressure. The body (44) of ignitable combustible material comprises a solid binder and an oxidizing agent. The binder is a block copolymer comprising blocks of an amorphous polymeric monomer in an alternating sequence with blocks of a crystalline polymeric monomer. A preferred block copolymer comprises a long chain polyether glycol as the amorphous polymeric monomer and a polybutylene terephthalate as the crystalline polymeric monomer.
