A base fabric for an airbag is formed of a polyamide fiber, wherein a CV value of a weaving density for every 20 cm in a base fabric weft direction is equal to or less than 0.5%, and original-yarn strength usage rates in the warp direction and the weft direction are equal to or more than 85%.

Provided is an airbag which further reduces the degree of injury to a vehicle occupant while also exhibiting sufficient occupant protection performance using less output from the inflator, by both preventing airbag internal pressure from rising excessively when making contact with the occupant and increasing the speed of deployment in an occupant-protection area. This hollow-weave airbag has an opening in a main chamber that inflates for the purpose of occupant protection, a structure wherein a first yarn extending separatingly from a first fabric layer of the opening to a non-inflating portion is caught on a float yarn extending on the inside of a second fabric layer and subsequently caught on a float yarn extending on the inside of the first fabric layer, this structure being repeated at least once and forming a pair with another structure wherein a second yarn extending separatingly from the second fabric layer of the opening to the non-inflating portion is caught on the float yarn extending on the inside of the first fabric layer and subsequently caught on the float yarn extending on the inside of the second fabric layer, this structure being repeated at least once.

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.

Provided is an airbag base fabric that has a low air permeability sufficient to ensure the safety of occupants and heat resistance sufficient to withstand high-power, high-temperature gas generated from a recent downsized inflator, and that is capable of being packaged compactly. Also provided is an airbag comprising the base fabric. An airbag base fabric comprising a synthetic fiber multifilament having a total fineness of 500 to 750 dtex, the airbag base fabric having an areal weight of 225 to 245 g/m.sup.2, air permeability at 20 kPa of 0.2 to 0.8 L/cm.sup.2/min, and edgecomb resistance according to the ASTM D 6479 method of 300 to 600 N in both warp and weft directions.

In one aspect, an apparatus for helping to protect an occupant of a vehicle includes a curtain airbag having a stored condition in which the curtain airbag is deflated, flattened, and rolled and/or folded. A wrap includes an integral woven portion of the curtain airbag formed from a fabric extension of an upper edge of the curtain airbag. The wrap has a first end portion where the wrap merges with the upper edge of the curtain airbag, and an opposite, free second end portion. The wrap is configured to wrap about a circumference of the rolled and/or folded curtain airbag. The second end portion is configured to connect to the first end portion of the wrap to secure the wrap on the curtain airbag and package the curtain airbag in the stored condition.

A base fabric for an airbag has a puncture load equal to or more than 6.0 N, wherein values obtained by dividing a bending stiffness (method A of JIS L 1096(2010)8.21) in each of a warp direction and a weft direction by a cover factor are equal to or less than 0.030 mm.

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 surface wherein at least a portion of the yarn on the top surface or at least a portion of the yarn on the bottom surface has fibers with a permanently modified cross-section and 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 base fabric for an airbag is formed of a polyamide fiber, wherein a CV value of a weaving density for every 20 cm in a base fabric weft direction is equal to or less than 0.5%, and original-yarn strength usage rates in the warp direction and the weft direction are equal to or more than 85%.

An isocyanate-functional prepolymer comprises the reaction product of: (A) a polyol; (B) an organopolysiloxane having at least two carbinol-functional groups per molecule; and (C) a polyisocyanate. Components (A) to (C) are utilized to provide a stoichiometric excess of isocyanate-functional groups in component (C) over the total amount of isocyanate-reactive groups of components (A) and (B). An isocyanate component comprising the isocyanate-functional prepolymer is also disclosed. The isocyanate component also comprises (E) a filler. In addition, a composition is disclosed, which comprises the isocyanate component and an isocyanate-reactive component. Further, a method of preparing a coating with the composition is disclosed, which method comprises applying the composition on a substrate and forming the coating from the composition on the substrate. A coated substrate comprising the substrate and a coating disposed on the substrate, the coating being formed from the composition, is additionally disclosed.
