Abstract
An inflatable air bag cushion for use in a vehicle restraint system that reduces the load experienced on the peripheral seam of a driver or passenger air bag to reduce or prevent combing of the cushion fabric. A sacrificial stitched seam 26 is sewn inboard of the standard peripheral seam 20 on the cushion. Upon inflation, the sacrificial seam tears at a predetermined cushion pressure slightly lower than the maximum. The outer stitched seam, composed of a stronger thread, survives throughout the cushion deployment. The final load experienced by the outer stitched seam and adjacent fabric is reduced. As a result, lower strength fabrics may be utilized which will reduce overall cushion costs.
