Abstract
An airbag canister vent is attached to or resides within an airbag module of an automobile. The module has a housing, within which resides a gas generator, an airbag, a tether cord, and a housing vent valve configured to close in accordance with the tether length that connects the airbag and the housing vent valve. The tension or any slack in the tether is governed by the discharge distance of the airbag from the canister. The canister vent may be a rotating disk that gradually closes as the airbag moves toward a seat occupant or a movable ball valve with a tether pin that remains open until the bag is discharged far enough from the canister to pull a tether pin from the ball causing the pressurized gas in the canister to forcibly lodge the ball against the vent hole wall thereby forming a seal and closing the valve.
