Abstract
【解決手段】可膨張チャンバ(3)を形成する膨張式エアバッグ(1)を開示する。本エアバッグは、該エアバッグの周壁内に設けられた内側弾性膜(5)を含み、ガス抜き穴(7)が、弾性膜(5)を貫通して形成される。エアバッグの外側上には、外側膜(8)が設けられ、外側膜(8)は、内側膜(5)の少なくとも一部及びガス抜き穴(7)を横切って延びる。外側膜(8)は、内側膜(5)及びガス抜き穴(7)の上方に襞(10)を形成する。襞(10)は、内側膜(5)が該襞(10)から離れている時にガス抜き穴(7)からの出口流路を形成するように開放している。内側膜(5)は、可膨張チャンバ(3)内の内部圧力が所定値を超えた時に伸張して襞(10)に当接してガス抜き穴(7)の周りを密閉するように構成されている。
