Abstract
Inflatable devices such as airbags are detailed. The bags may be formed of components well nested on linear rolls of material, reducing material wastage. The airbags additionally may, in some cases, be formed of components lacking curved surfaces; in certain cases the bag components additionally may have complementary surfaces that, although formed of straight segments, resemble convex and concave shapes.
