Abstract
Abstract An air bag module for venting inflation gas if an out-of-position vehicle occupant is too close to the module for proper air bag deployment. The module has an air bag canister comprising a side wall having gas channel port to communicate with the ambient air, an inflator, an air bag cushion, a deployment door, a structural gas channel, and a venting system connecting the structural gas channel to the at least one gas channel port. The venting system permits venting of gas through the gas channel port when the out-of-position occupant applies sufficient force on the deployment door to prevent the air bag cushion from reaching a fully deployed condition.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
156 words
An air bag module comprising: an air bag canister having at least one side wall, the at least one side wall having at least one gas channel port therein to communicate with ambient air pressure; an air bag cushion attached to the canister; an inflator attached to the air bag canister for providing gas; a deployment door attached to the canister; a structural gas channel pivotally connected to the side wall proximate to the gas channel port and configured to communicate with the at least one gas channel port to provide venting of gas provided by the inflator to the ambient air when the air bag cushion is in a substantially non-deployed condition; and a venting system connecting the structural gas channel to the at least one gas channel port and operative to prevent venting of gas through the gas channel port from the canister when the air bag cushion is in a substantially deployed condition.
Claim 2
Dependent Claim
156 words
An air bag module comprising: an air bag canister having at least one side wall, the at least one side wall having at least one gas channel port therein to communicate with ambient air pressure; an air bag cushion attached to the canister; an inflator attached to the air bag canister for providing gas; a deployment door attached to the canister; a structural gas channel pivotally connected to the side wall proximate to the gas channel port and configured to communicate with the at least one gas channel port to provide venting of gas provided by the inflator to the ambient air when the air bag cushion is in a substantially non-deployed condition; and a venting system connecting the structural gas channel to the at least one gas channel port and operative to prevent venting of gas through the gas channel port from the canister when the air bag cushion is in a substantially deployed condition.
Claim 3
Dependent Claim
86 words
The air bag module of claim 1 wherein the venting system comprises a non-porous fabric gas channel pivotally connecting the structural gas channel to the side wall proximate the gas channel port and a tether connecting the structural gas channel to the air bag cushion wherein during air bag deployment, the air bag cushion is inflated thereby pulling the tether taut and pivoting the structural gas channel and the non-porous fabric gas channel to a position wherein the non-porous gas channel blocks the gas channel port.
Claim 4
Dependent Claim
91 words
The air bag module of claim 1 wherein the structural gas channel is pivotally connected to the canister and the venting system comprises a non-porous fabric gas channel pivotally connecting the structural gas channel to the side wall proximate the gas channel port and a tether connecting the structural gas channel to the air bag cushion wherein during air bag deployment, the air bag cushion is inflated thereby pulling the tether taut and pivoting the structural gas channel and the non-porous fabric gas channel upwards thereby blocking the gas channel port.
Claim 5
Dependent Claim
14 words
The air bag module of claim 1 wherein the structural gas channel is semi-rigid.
Claim 6
Dependent Claim
122 words
An air bag module comprising: an air bag canister having at least one side wall, the at least one side wall having a gas channel port to communicate with ambient air pressure; an air bag cushion attached to the canister; an inflator attached to the canister for providing gas; a deployment door attached to the canister; a structural gas channel to communicate with the gas channel port and to provide venting of the gas provided by the inflator; a non-porous fabric gas channel pivotally connecting the structural gas channel to the side wall proximate the gas channel port to provide a passageway from the inflator to ambient air pressure; and a tether connecting the air bag cushion to the structural gas channel.
Claim 7
Dependent Claim
122 words
An air bag module comprising: an air bag canister having at least one side wall, the at least one side wall having a gas channel port to communicate with ambient air pressure; an air bag cushion attached to the canister; an inflator attached to the canister for providing gas; a deployment door attached to the canister; a structural gas channel to communicate with the gas channel port and to provide venting of the gas provided by the inflator; a non-porous fabric gas channel pivotally connecting the structural gas channel to the side wall proximate the gas channel port to provide a passageway from the inflator to ambient air pressure; and a tether connecting the air bag cushion to the structural gas channel.
