Abstract
Airbags and airbag assemblies are disclosed that include passive adaptive venting. The disclosed embodiments include an airbag cushion to define an inflation chamber and that include a set of vents. The set of vents is disposed through a panel of the airbag cushion. The set of vents allow egress of inflation gas from the inflation chamber and to be in an open state when a degree of compression of the airbag cushion is below a threshold level. The set of vents is configured to be in a closed state and/or obstructed by a vehicle surface of a vehicle structure when the degree of compression of the airbag cushion exceeds the threshold level.
