An airbag module according to various implementations includes an inflatable cushion, a folding tab, and an inflator. The inflatable cushion includes a first panel and a second panel, each of the first and second panels including an inner surface and an outer surface. When the outer surfaces of the first and second panels are coupled together to form an inverted seam, the folding tab is coupled between the respective outer surfaces of the first and second panels. As a result, the inflatable cushion includes an increased strength while maintaining an ease of assembly using current inflatable cushion folding machines.

Provided is an airbag which can be easily manufactured though it is provided with a tether inside, and has a reduced fear of gas leakage from a joint region. The airbag includes a joint region of outer circumferential edges of a pair of walls. The joint region includes, between the outer circumferential edges of the pair of walls, a sealing member which has elasticity, and has adhesiveness in an unsolidified state. The joint region is formed by such a sewing that runs a sewing thread through an application area of the sealing member. A tether connects the pair of walls. The joint region includes a region in which the sealing member has a solidified, thus non-adhesive surface, and is pressed against at least one of the walls by the non-adhesive surface, and penetrated by the sewing thread in that state.

An airbag comprises: first and second fabric panels; a seam at a seam area of the first and second fabric panels, the seam joining the first and second fabric panels to each other; and a sacrificial elastomer line at a location inward of the seam area, the sacrificial elastomer line joining the first and second fabric panels to each other at the location.

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).

An inflatable cushion for a side of a vehicle is provided, the inflatable cushion having a first portion of material; a second portion of material, the first portion of material being secured to the second portion of material to define the inflatable cushion; wherein at least a portion of a peripheral edge of the inflatable cushion is defined by a seam wherein an inner surface of the first portion is secured to an inner surface of the second portion only by a plurality of stitches; and wherein a strip of a third portion of material is applied to the seam of an outer surface of either the first portion or the second portion when the plurality of stitches are applied.

A polyvinyl alcohol (PVA)-based airbag base fabric aqueous coating material is described. A blocked polyisocyanate component (B-NCO) and liquid polyol are added to polyvinyl alcohol as a cross-linkage improver and a plasticizer, respectively. The B-NCO is composed of or based on a medium-molecular-weight form as a polyether-modified prepolymer, and used concurrently with a low-molecular-weight form in a small amount. The base fabric coating material is applied on one or both of the sides of a cloth of the base fabric and heated. The acquired coating film is a water-insoluble coat and the coating has excellent heat and moisture resistance (hot water resistance) and flexibility.

Inflatable airbag for a vehicle which is deployed in the event of an accident involving the vehicle to provide protection for an occupant of the vehicle includes a plurality of ribbons coupled together to define an enclosed, fluid-retaining space and a layer of film laminated on at least one of an outer side of the woven ribbons and an inner side of the ribbons. The ribbons may be made from polypropylene, polyethylene, polyester or polyamide and the layers of film may be made from polyethylene, polyurethane, polyester or polyamide. The ribbons and layers of film may be made of the same or different materials.

An airbag comprises: first and second fabric panels; a seam at a seam area of the first and second fabric panels, the seam joining the first and second fabric panels to each other; and a sacrificial elastomer line at a location inward of the seam area, the sacrificial elastomer line joining the first and second fabric panels to each other at the location.
