ROLL-OVER AIR BAG WITH REINFORCED SEAL AND METHOD OF SEALING

摘要

A roll-over airbag 10 having an upper fabric panel 15 and a lower fabric panel 20 perimetrically bonded to the upper fabric panel 15. This perimetric joint is reinforced with a lap joint 30 defining a reinforced interior seal. The height and/or thickness of the roll-over airbag 10 can be limited by either selecting a configuration that is self limiting or by limiting the displacement of the upper and lower fabric panels 15 and 20 from one another during expansion of the roll-over airbag 10 by at least one tether member 40 disposed within roll-over airbag 10. Further, a method for producing a flatjoint seam in a roll-over airbag in which the lap joint is sealed flat and steps are taken to prevent the upper and lower portions of the lap joint from adhering to one another.
