Abstract

An airbag assembly may include an inflatable curtain airbag with a stowed configuration and a deployed configuration. The inflatable curtain may have a first protection zone and a second protection zone that inflates forward of the first protection zone to provide enhanced protection. The second protection zone may be folded against the first protection zone so that, during deployment, the second protection zone pivots to unfold relative to the first protection zone. The airbag assembly may have a restraint member that limits the ability of the second protection zone to unfold to a configuration parallel to the first protection zone, thereby keeping the second protection zone at an optimal location to protect the vehicle occupant from rollover and/or small overlap or oblique collisions. The restraint member may be a tether with ends secured proximate the top of the second protection zone and the top of the first protection zone.
