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 or rearward 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. Attachment features such as tack stitching may be used to secure the folded portions together. The tack stitching may be designed to break during deployment of the airbag such that the first protection zone inflates first, followed by a proximal portion of the second protection zone, and then by a distal portion of the second protection zone.
