Abstract
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. In order to limit the height and/or thickness of the roll-over airbag 10 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, at least one tether member 40 is disposed within roll-over airbag 10. Also a through-opening is defined by passageway 85 to permit passage of a seat belt through the roll-over airbag 10 while stored in a deflated condition. In the preferred embodiment, the passageway 85 is defined by a pleated channel member 90. The pleats 96 allow the channel member 90 to fold flat when the roll-over airbag 10 is deflated and allows substantially uniform expansion of the roll-over airbag 10 during inflation.
