Abstract: A knee airbag (KAB) can be constructed with an adaptive vent for reducing internal cushion pressure when the deployment path is obstructed. Obstruction may occur, for instance, by an out-of-position occupant, or when the occupant's legs are in close proximity to the deploying KAB. By reducing the cushion pressure through adaptive venting, a potential for injury due to the deploying KAB can be reduced. External straps can be used to close the vents when no obstruction is encountered. With an adaptive KAB vent design, a direct contact between the occupant and the KAB adaptive vent straps can determine an amount of venting. In addition, the straps may be designed so that they are adaptive (tapered, positioned on an angle, or using different spacing) to account for different occupant sizes/knee spacing/knee contact locations.
