A base fabric for airbag is formed by a hollow weave in which a warp yarn and a weft yarn are woven to provide a bag portion having two woven fabric layers and a closing portion having one woven fabric layer, and includes a positioning hole. The positioning hole is formed by the closing portion on a peripheral edge thereof, and a non-weave portion in which the warp yarn and the weft yarn are not woven in an inner side of the closing portion.

An airbag fabric made of polyamide filaments, wherein the polyamide filaments are made of at least 60% by weight of a bio-based monomer.

An uncoated woven fabric of yarn formed from synthetic fibers woven in the warp direction and weft direction to form a top surface and a bottom wherein the fabric is treated in order to permanently modify the fabric surface structure such that fibrillous or apical structures extend approximately normal to the surface of the fabric, and at least a portion of the yarn on the top surface and/or at least a portion of the yarn on the bottom surface have warp and weft fibers which are melt fused together at their intersections, and a majority of the yarn on the top surface and/or a majority of the yarn on the bottom surface have fibers with a permanently modified cross-section that are fused together, is provided. Methods for production and use of this fabric in application to products such as automobile airbags, sailcloths, inflatable slides, temporary shelters, tents, ducts, coverings and printed media are also provided.

A non-coated air bag fabric according to the present invention is woven using fibers containing polyethylene terephthalate as a main raw material, the fabric has a cover factor of 2350 or more, and a single fiber fineness of a yarn that constitutes the fabric is 2.0 dtex to 4.0 dtex inclusive.

A non-coated air bag fabric is a fabric constituted by synthetic fibers, and the fabric has a cover factor of 2300 or more, a height difference between a recess and a protrusion on a surface of the fabric is less than 130 μm, and a P ratio expressed by the following equation is 0.85 to 1.15 inclusive. The P ratio=HP.sub.100/HP.sub.80 where HP.sub.80 indicates air permeability after a load is applied to the fabric under a condition of 80° C., and HP.sub.100 indicates air permeability after a load is applied to the fabric under a condition of 100° C.

An addition-curable silicone rubber composition and an air bag are provided. The addition-curable silicone rubber composition is characterized by comprising: (A) 100 parts by mass of an alkenyl-group-containing organopolysiloxane; (B) an organohydrogenpolysiloxane, contained in such an amount that the number of moles of silicon-atom-bonded hydrogen atoms contained in (B) component is 5 or greater per mole of the alkenyl groups contained in (A) component; (C) an addition reaction catalyst, contained in an amount of 1-500 ppm, in terms of the mass of the catalyst metal element, of the total mass of (A) and (B) components; (D) 0.1-50 parts by mass of finely powdery silica; (E) 0.1-5.0 parts by mass of an adhesion improver [a mixture comprising (E-1) an organohydrogenpolysiloxane, (E-2) an alkoxysilyl-modified isocyanurate compound, and (E-3) an organosilicon compound]; and (F) 0.1-5.0 parts by mass of a condensation catalyst.

Provided is an airbag base fabric that is a woven fabric constituted by a yarn containing polyethylene terephthalate as the main raw material, the yarn constituting the woven fabric having a total fineness of 280 to 500 dtex and a single fiber fineness of 1.0 to 3.9 dtex, the woven fabric having a cover factor of 2400 to 2800, and the D-value calculated from the thickness D.sub.1 of a single sheet of the base fabric and the thickness D.sub.10 of ten sheets of the base fabric that are stacked together being 0.9 or less, where the D-value is calculated using a formula A below:
D=D.sub.10/(D.sub.1×10).  Formula A:

A side airbag apparatus includes an airbag that is configured to be deployed and inflated between a body side portion of a vehicle and an occupant seated in a seat in a passenger compartment by a pressure of gas supplied from an inflator. The airbag includes an outer bag and an inner bag, which is provided in the outer bag and accommodates the inflator. The inner bag includes an upper-side inflation portion, which projects forward when inflated to correspond to the shoulder of the occupant, a lower-side inflation portion, which projects forward when inflated to correspond to the lumbar region of the occupant, and a recessed portion, which is provided between the upper-side inflation portion and the lower-side inflation portion. The inner bag includes a connecting hole that connects the inside and the outside of the inner bag to each other.

An air bag device in which due to coupling between airbag chambers, a passenger is directly restrained in a seat located at each of various positions such that the air bag device responds to various collision modes. The air bag device includes a bridge chamber unfolding in a shape covering a first side of a seat and a front thereof, and a hook chamber unfolding in a shape covering a second side of the seat and the front thereof and coupled to the bridge chamber by a first coupling device in a part overlapping with the bridge chamber.

An airbag device includes: an inflator generating gas; a bag-shaped airbag configured to be inflated and deployed, the airbag having a vent hole through which the gas is discharged; and a gas flow adjustment member including: a gas receiving part covering the vent hole; an opening edge portion formed at a portion of an outer peripheral edge of the gas receiving part; and an attachment edge portion for attaching the outer peripheral edge except the opening edge portion to the airbag, the attachment edge portion having an opposite portion which is opposite to the opening edge portion, in which the gas flow adjustment member is provided with at least one pleat portion formed such that a fold extends from the opening edge portion toward the opposite portion, and the at least one pleat portion is configured such that the fold is kept folded at the attachment edge portion.
