Abstract
A method for manufacturing a one-piece woven (OPW) air bag includes method for manufacturing an OPW airbag. The method includes providing yarns, warping the yarns on at least one beam of a loom, and simultaneously weaving yarns into a fabric air bag structure having two layer portions defining an inflatable volume and single layer portions forming seams delimiting the inflatable volume. A plurality of the yarns overlay one another to form nonwoven alignment elements in at least one of the single layer portions. The air bag structure is cut to define the OPW air bag. The alignment elements are aligned with alignment elements on a panel. The air bag structure is sewn to the panel with the alignment elements aligned with one another.
