Air bag system
First Claim
1. An air bag system comprising:
- an inflator operable to release inflation fluid;
an inflatable air bag inflatable upon release of inflation fluid from said inflator; and
a vent opener operatively connected to said air bag and selectively movable from a first position to a second position to create a cushion vent within said air bag for venting inflation fluid.

Abstract
An air bag system includes an inflator, an inflatable air bag, and a vent opener operatively connected to the air bag and selectively movable from a first position to a second position to create a cushion vent within the air bag for venting inflation fluid. A movable member operatively connects to an air bag housing, with a retention member extending through a connector arm to selectively connect the movable member and the vent opener. A sensing tether is operable to selectively release the retention member. The air bag system may further include a switch, with a sensing tether operable to change the state of the switch if any portion of the air bag passes a predetermined plane during inflation thereof.

14. An air bag system comprising:
-
an inflator operable to release inflation fluid;
an inflatable air bag inflatable upon release of inflation fluid from said inflator;
an air bag housing substantially surrounding said air bag;
a vent opener operatively connected to said air bag and selectively movable from a first position to a second position to create a cushion vent within said air bag for venting inflation fluid;
a movable member operatively connected to said housing and movable from an undeployed state to a deployed state;
a connector arm selectively connecting said movable member and said vent opener;
a retention member operable to selectively connect said connector arm to one of said vent opener and said movable member; and
a flexible sensing tether extending between said air bag and said retention member, said sensing tether operable to release said retention member to disconnect said connector arm from said one of said vent opener and said movable member, thereby disconnecting said movable member and said vent opener;
wherein movement of said movable member from said undeployed state to said deployed state causes movement of said vent opener from said first position to said second position when said movable member and said vent opener are connected. - View Dependent Claims (15)
