ABSTRACT:
An airbag for use in an occupant protection system has a venting mechanism which allows inflation gas to vent from the airbag only after a predetermined inflation pressure is attained. The venting mechanism includes a ventilation opening and a sealing member overlying the opening which inhibits the venting of the inflation gas. The sealing member has a frangible region which remains intact below the predetermined inflation pressure, but which breaks open when the predetermined inflation pressure is exceeded.
