A method for manufacturing a one-piece woven (OPW) air bag includes providing yarns having a spin finish and warping the yarns on at least one beam of a loom. The yarns are simultaneously woven into a fabric air bag structure having two layer portions defining an inflatable volume and single layer portions forming seams delimiting the inflatable volume. The air bag structure is coated to cover the spin finish. The coated air bag structure is cut to define the one-piece woven air bag.

Methods for production of automobile airbags with decreased air leakage and an increased duration of their inflated state, as well as airbags produced in accordance with these methods are provided.

The invention describes an airbag (10), in particular a head side airbag (10) or a head-thorax side airbag, including at least two opposite fabric layers (12, 14) which form at least one inner wall (13) and one outer wall (15) of the airbag (10), wherein the airbag (10) is manufactured in one piece by a multi-layer weaving process in which the fabric layers (12, 14) are interwoven at least in a peripheral region (16), with a gas generator mount (18) for an external gas generator (20) being disposed in either of the two fabric layers (12, 14). The invention further describes an airbag module (8) comprising an airbag (10) according to the invention as well as a method for manufacturing a one-piece-woven airbag (10) and a method for manufacturing an airbag module (8).

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.

A method for manufacturing a one-piece woven (OPW) air bag includes providing yarns and warping the yarns on at least one beam of a loom. Yarns are simultaneously woven into a fabric air bag structure having two layer portions defining both an inflatable volume and non-inflatable portions and single layer portions forming seams delimiting the inflatable volume. The air bag structure is cut to define the OPW air bag and at least one opening extending through only one layer of the two layer portions.

A curtain airbag for a vehicle may include a curtain airbag cushion including a rear panel disposed at a door window side of the vehicle and a front panel disposed inside the vehicle, a protrusion formed by bending the curtain airbag cushion to protrude toward the inside of the vehicle, and connections for attaching upper and lower ends of a protruding part of the protrusion.

A method for manufacturing a one-piece woven (OPW) air bag includes providing yarns and warping the yarns on at least one beam of a loom. Yarns are simultaneously woven into a fabric air bag structure having two layer portions defining both an inflatable volume and non-inflatable portions and single layer portions forming seams delimiting the inflatable volume. The air bag structure is cut to define the OPW air bag and at least one opening extending through only one layer of the two layer portions.

An airbag and a method for manufacturing the airbag. The airbag is manufactured by weaving yarns to form a one-piece woven (OPW) airbag having inflatable portions and non-inflatable portions. The non-inflatable portions are woven with varying weave patterns so as to form recesses in the surface of the airbag in the form of an indicia.

A passenger protecting device including: an airbag device including an airbag that receives a supply of gas from an inflator and is inflated and expanded, by a front expanding portion that includes a front inflating portion to be inflated and expanded at a seat front side of the head portion and at least one of a chest portion and shoulder portions of the passenger, and a pair of left and right lateral expanding portions that include lateral inflating portions that are connected to the front expanding portion and are inflated and expanded at sides of the head portion of the passenger; and a position changing device that changes an inflated and expanded position of the airbag in a seat transverse direction, in accordance with a direction of collision of a collision body with respect to the vehicle seat.

Fabrics for inflatable airbags including one or more aperture sections are disclosed. The aperture sections can be formed in woven fabric panels of the inflatable airbags. Methods of weaving fabric panels including aperture sections for inflatable airbags are also disclosed. The aperture sections may define vents, or the aperture sections may receive a portion of an inflator, a lead wire, and/or a mounting hardware component.
