Abstract

A depth to which an inflatable airbag can deploy may varied by internal tethers. If the tethers are coupled to a release assembly, then in an unreleased state, the tethers can limit the depth of airbag deployment; however, if the tethers are released, the airbag can deploy of a full depth.
