High internal pressure fabric airbag with exposed inflator

摘要

An inflatable fabric cushion is disclosed that can maintain a high internal pressure while having an exposed inflator squib. The inflatable cushion has a precision opening sized to be commensurate with a diameter of the inflator squib. The precision opening tightly circumscribes the inflator to limit leakage of inflation gas when the squib projects out of the opening. The cushion also has a throat through which the inflator may be inserted into the cushion. After the inflator is inserted into the cushion, the throat is sealed closed by wrapping the throat around the inflator housing and being cinched when the airbag assembly is mounted on a vehicle.
