Abstract
A novel airbag curtain fold configuration for a safety restraint system, especially well suited to protect occupants of a vehicle from lateral impact is described. One or more airbag curtains are provided to inflate between an occupant and a lateral surface, such as a door or side window. The airbag curtain includes a first and second side. A fold portion is configured adjacent the first side and a rolled portion is configured opposite the fold portion adjacent the second side of the airbag. Attachment tabs may extend from an edge of the airbag curtain beyond the rolled and fold portions to facilitate attachment of the airbag curtain to a vehicle as part of an airbag system.A method for folding an airbag curtain is described. A first edge of the airbag curtain is folded to a position adjacent a first side of the airbag curtain. A second edge of the airbag curtain is rolled toward the first edge of the airbag curtain until the rolled portion is substantially adjacent the fold portion on an opposing side of the airbag curtain.
