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 double-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 in the form of a forward tether or a first tether secured to the forward tether such that the restraint member exerts outboard force on the second protection zone during deployment to help control deployment of the second protection zone. Portions of the first and second protection zones may be fold-over sewn together to control the angle at which the second protection zone unfolds relative to the first protection zone.
