1. An airbag cushion comprising at least one fabric panel and at least one seam in order to connect either (a) at least two fabric panels or (b) at least two portions of said at least one fabric panel, wherein said airbag cushion possesses an effective seam usage factor of less than 0.080 and wherein said at least one fabric panel is symmetrical about a first line of symmetry and has a plurality of substantially straight edges, said edges including:

  • first and second edges substantially parallel to said line of symmetry, each of said first and second edges having a respective first end and a respective second end;

    a third edge, said third edge having a first end and a second end, said first end of said third edge intersecting said first end of said first edge, and said third edge extending from said first edge toward said line of symmetry,a fourth edge, said fourth edge having a first end and a second end, said first end of said fourth edge intersecting said first end of said second edge, said fourth edge extending from said second edge toward said line of symmetry, andat least one additional edge connecting the second end of the first edge with the second end of the second edge;

    said at least one fabric panel comprises a cutout encompassing a portion of said line of symmetry and extending from said second ends of said third and fourth edges to said line of symmetry, and when said fabric panel is folded about said line of symmetry and said third edge is seamed to said fourth edge to form a connected composite and said connected composite is unfolded;

    said first, second, and said at least one additional edge form a substantially oblong opening, andsaid cutout forms a second opening opposite said substantially oblong opening.
