Abstract
An apparatus for helping to protect an occupant of a vehicle includes a curtain airbag having a packaged condition in which the curtain airbag is rolled and/or folded for installation in the vehicle. The curtain airbag is configured to inflate and deploy between the occupant and a side structure of the vehicle. A deployment wrap includes a sheet of material configured as a loop to extend around the curtain airbag in the packaged condition. The deployment wrap is configured to undergo tension in response to inflation of the curtain airbag. The tension acts on the curtain airbag to help control the initial deployment of the curtain airbag. The deployment wrap is rolled up along its length, forming a roll that takes up the material of the deployment wrap and causes the deployment wrap to constrict around the curtain airbag.
