Abstract:
A roll-over airbag for an automobile self-inflating restraint system, said roll-over airbag comprising:a first woven fabric panel having a perimeter of a pre-selected length, said woven fabric incorporating a weldable coating so as to be impervious to an expansion fluid;a second woven fabric panel perimetrically bonded to said first fabric panel, said woven fabric incorporating a weldable coating so as to be impervious to an expansion fluid;at least one port opening provided in said first fabric panel for connecting said roll-over airbag to an inflator to allow communication of an expansion fluid from the inflator to said roll-over airbag;a reinforced perimeter seal of said preselected length, wherein said reinforced perimeter seal is reinforced by at least one securement member disposed proximate said perimeter, wherein each said at least one securement member has an upper portion bonded to said first fabric panel and a lower portion bonded to said second fabric panel thereby distributing stress associated with expansion of said roll-over airbag over a larger surface area such that a tear stress is transformed by said at least one securement member into a shear stress; andat least one tether disposed within said airbag for limiting displacement of said first and second fabric panels from one another, wherein said at least one tether is defined by at least a two-ply member defining a I-shaped cross section and having a first end bonded to said first fabric panel and a second end bonded to said second fabric panel and defining concave edge portions.
