    摘要: In accordance with one aspect of the present invention, an inflatable restraint system for use in a transportation vehicle having a dash panel and space for an operator and a passenger is provided. The restraint system includes at least one gas generator housed within the dash panel and an inflatable cushion in fluid communication with the gas generator. The inflatable cushion which may be formed from a single blank of material includes an impact portion for contact with the passenger during a frontal collision and a neck portion which extends away from the impact portion towards the gas generator. The impact portion of the inflatable cushion has a seam free contact surface for contact with the passenger during a collision event and a rear surface which opposes the dash panel upon inflation. The impact portion and the neck portion are adjoined and enclosed by a plurality of substantially straight seams. The inflatable protective cushion is characterized by a substantially arcuate inflated profile such that the impact portion of the cushion extends in curved relation at least partially around the dash panel during a collision event. The inflatable protective cushion is formed from one or more precut panels of fabric or other base material which panels have geometric configurations such that the precut panels may be cut according to a repeating pattern from a roll of fabric or other base material in a close packed orientation substantially with minimal waste across the interior of such roll of fabric. The inflatable protective cushion being further characterized by a low structural seam assembly time.
