Air bag module with actuatable vent part
First Claim
1. An apparatus for helping to protect an occupant of a vehicle, said apparatus comprising:
- an inflatable vehicle occupant protection device;
an inflation fluid source actuatable to provide inflation fluid for inflating the protection device;
a structure for supporting the protection device in the vehicle, the structure comprising a vent opening for venting inflation fluid from the protection device;
a vent member connectable to the structure to block inflation fluid flow through the vent opening;
actuatable means for detaching the vent member from the structure and moving the vent member away from the vent opening to permit inflation fluid flow through the vent opening; and
a flexible elongated member having a first end connected to the vent member and a second end connected to the structure, the second end of the flexible elongated member being connected to the structure by a fastener that also secures a retainer to the structure, the retainer being for securing the protection device to the structure, the flexible elongated member tethering the vent member to the structure after the vent member is detached from the structure.

Abstract
An apparatus (10b) includes an inflatable vehicle occupant protection device (14b). An inflation fluid source provides inflation fluid for inflating the protection device (14b). A structure (320) for supporting the protection device (14b) includes a vent opening (40b) for venting inflation fluid from the protection device. A vent member (300) is connectable to the structure (320) to block inflation fluid flow through the vent opening (40b). An actuatable device (120b) when actuated breaks the connection between the vent member (80b) and the structure (320) and moves the vent member away from the vent opening (40b) to permit inflation fluid venting. A flexible elongated member (350) has a first end (352) connected to the vent member (300) and a second end (354) connected to the structure (320). The member (350) secures the vent member (300) to the structure (320) after the connection between the vent member and the structure is broken.
