First Claim
1. An airbag assembly comprising:
- an inflatable cushion;
a throat in the cushion for receiving an inflator into the cushion; and
a precision opening in the cushion for receiving an inflator squib, the opening having a diameter corresponding in size to the inflator squib.

Abstract
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.

25. A method for maintaining a high internal pressure of a fabric airbag, comprising:
-
obtaining an inflatable fabric cushion having a throat;
forming a hole in the fabric cushion with a diameter the same size as a diameter of an inflator squib;
inserting an inflator into the fabric cushion through the throat, the inflator having a housing and a squib;
projecting the inflator squib outside the hole in the fabric cushion while maintaining the inflator housing inside the fabric cushion; and
sealing the throat to prevent the passage of inflation fluid through the throat. - View Dependent Claims (26, 27)
