The invention relates to an OPW (one piece woven) airbag comprising warp threads and weft threads which are woven into at least three woven fabric layers, a lower fabric layer (UG), an upper fabric layer (OG), and a central fabric layer (MG) arranged therebetween. The warp threads and weft threads of the central fabric layer (MG) protrude out of the central fabric layer (MG) and completely float between the lower fabric layer (UG) and the upper fabric layer (OG) in a first sub-region (ETB) of the OPW airbag and are integrated into the lower fabric layer (UG) or into the upper fabric layer (OG) in a second sub-region (ZTB) of the OPW airbag.

A restraint performance improvement portion of a curtain airbag device for a vehicle is provided at a location of a lower end portion of a curtain airbag which location corresponds with a vehicle seat when the vehicle seat is in a comfortable state. The restraint performance improvement portion inhibits a head area of a vehicle occupant from slipping past the curtain airbag to a vehicle width direction outer side thereof when the vehicle occupant is being restrained.

The present disclosure is directed to provide a multilayer film for use in an air bag, which provides sufficient adhesiveness and blocking tendency in a well-balanced manner. The multilayer film for use in an air bag according to the present disclosure includes an adhesive layer and an outer layer. The adhesive layer includes a resin having a glass transition temperature from 0° C. to 80° C. and a melting point from 100° C. to 160° C. The outer layer includes a resin having a melting point higher than the melting point of the resin included in the adhesive layer by 20° C. or higher. Further, an air bag according to the present disclosure includes a synthetic fiber fabric and the aforementioned multilayer film for use in an air bag, in which the adhesive layer in multilayer film is laminated with the synthetic fiber fabric.

An airbag textile containing a woven textile having an inner side and an outer side, a primer layer on the outer side of the textile and a gas barrier layer on the primer layer. The primer layer contains a first thermoplastic polymer and has a surface roughness and a plurality of holes extending at least partially through the thickness of the primer layer. The gas barrier layer contains a second thermoplastic polymer and at least partially fills in the surface roughness and holes of the primer layer.

A multilayer film, which is used upon being adhered to a fabric, includes an adhesive layer to be a side of the multilayer film to be adhered to the fabric, the adhesive layer including a thermoplastic polyester elastomer and a polymer having a Shore D hardness of less than 80; and a barrier layer bonded to the adhesive layer, the barrier layer including a thermoplastic elastomer.

A curable silicone adhesive having improved elongation-at-break and adhesive properties to various substrates, in particular synthetic textiles used in the manufacture of air bags, to be used, for example, as a joint sealer. These silicone compositions provide excellent adhesive properties such as peel strength and cohesive failure when used to seal joints/seams between two pieces of textile fabric. Airbag fabrics using such novel addition curable adhesive silicone compositions are also provided.

An airbag assembly for a motor vehicle including an inflator, an inflatable airbag and a protection device for protecting the throat and fill tube of the inflatable airbag. The inflator is configured for generating inflation gases having an effective exit gas temperature (EGT) less than or equal to 300 degrees Kelvin. The inflatable airbag is formed from one or more panels and defines an interior volume including a plurality of inflatable chambers expandable upon deployment from a stowed state to a deployed state. The interior volume of the inflatable airbag is in fluid communication with the inflator such that inflation gases are passed through the throat and directed to the plurality of inflatable chambers by the fill tube. The one or more panels are constructed from at least one material selected from a group consisting of polyethylene terephthalate (PET), nylon, and combinations thereof. The protection device lines the throat and at least a portion of the fill tube proximate the throat to protect the one or more panels of the inflatable airbag from heat and pressure of the inflation gases.

An OPW airbag having warp and weft threads woven together in at least three woven fabric layers: a lower fabric layer, an upper fabric layer, and a middle fabric layer therebetween. The weft threads of the middle fabric layer emerge from the middle fabric layer in a first partial region of the airbag and are tied partially to the upper fabric layer and partially to the lower fabric layer. The warp threads of the middle fabric layer emerge from the middle fabric layer in the first partial region of the airbag and float freely between the lower fabric layer and the upper fabric layer. The weft and warp threads of the middle fabric layer are incorporated into the lower fabric layer or into the upper fabric layer in a second partial region of the airbag or are tied to the lower or upper fabric layer at a few attachment points.

An addition curable liquid silicone rubber composition for airbag includes an organopolysiloxane which is liquid at 25° C. and contains two or more alkenyl groups bonded to silicon atoms within one molecule, an organohydrogenpolysiloxane containing two or more hydrogen atoms bonded to silicon atoms within one molecule, a silica fine powder having a BET specific surface area of 50 m.sup.2/g or more, a catalyst for hydrosilylation reaction, an organosilicon compound containing an adhesion-imparting functional group, an organopolysiloxane resin having a three-dimensional network structure, and iron(III) oxide monohydrate, α-iron(II) oxide, or both of them having a pH of 5 to 9.

An air bag base cloth according to the present invention includes a base cloth main body formed of synthetic fibers, and a synthetic resin layer with which at least one face of the base cloth main body is coated, and the moisture content measured in accordance with JIS L 1096.8.10 is 0.5% or less.
