A woven fabric for airbags has a high quality that can suppress generation of creases during refining, heat setting, and coating steps to be performed after weaving, has an excellent uniform applicability, and can suppress misalignment during cutting. A woven fabric for airbags consists of synthetic fibers, wherein a ratio of a selvedge flare amount R represented by equation (1) is 5.0% or less

S=?.sub.k=1.sup.n(W.sub.k?H.sub.k)/2

R=S/(200?F)?100(1)

wherein, S=selvedge flare amount, in cm.sup.2, W.sub.k=selvedge flare width, in cm, H.sub.k=selvedge flare depth, in cm, n is the number of selvedge flares, R is a ratio of a selvedge flare amount, in %, and F is a base fabric width, in cm.

The present disclosure describes a polyester fabric for airbags formed from a polyester fiber, which can reduce costs, and the polyester fabric for airbags has high restraint performance for receiving the occupant during deployment and maintains the performance at high levels even after aging, while maintaining the mechanical characteristics as a fabric for airbags. A polyester fabric for airbags has a resin provided on at least one surface wherein the polyester fabric has an optimized crimp ratio and has a scrubbing test count of 400 or more after aging treatment at 70? C. at 95% RH for 408 hours.

A side airbag for a vehicle includes a main chamber and a necking chamber. The main chamber has an opening for connecting to an inflator and a first thickness in an inflated condition. The necking chamber is peripherally surrounded by the main chamber and is connected to the main chamber by a restrictive vent. The necking chamber has a second thickness in the inflated condition less than the first thickness and is aligned with a targeted body area.

The purpose of the present invention is to provide a base fabric for an airbag and an airbag wherein the strength of sewn parts is high, pressure resistance is superior for an airbag during high-pressure deployment at high speeds, and pressure resistance can be maintained even after passage of time in heat. This base fabric for an airbag is characterized by being formed from woven polyamide fibers, and the retention of sewn part strength in the base fabric with heating before and after heat treatment for 400 hours at 140 C. being 70% or greater.

An airbag is disclosed, including a main bag section deployable in front of a passenger seat, a center bag section which is deployable in such a manner as to protrude towards an inboard side in a vehicle width direction out of the main bag section to an area beneath the rearview mirror. The center bag section includes, on the upper portion as deployed, a region that faces the rearview mirror in an up and down direction. The center bag section internally includes a regulating tether that is disposed generally along an up and down direction and connects the region of the upper portion of the center bag section facing the rearview mirror at airbag deployment and a region of a lower portion of the center bag section deployed beneath the region facing the rearview mirror in order to prevent contact between the center bag section and the rearview mirror.

Provided is a non-coated air bag fabric made from polyethylene terephthalate, and the fabric is woven using fibers containing polyethylene terephthalate as the main raw material, the fabric having a cover factor of 2300 or more, Z calculated using the equation below is 8200 or more, and a height difference between recesses and protrusions on the surface of the fabric is less than 130 ?m. Z=cover factor/thickness (mm).

An airbag system includes an airbag. The airbag system includes a base defining a track extending from a first end to a second end. The airbag system includes a carrier releasably fixed to the base and removable from the base at the second end. The airbag system includes a tether extending from the carrier and secured to the airbag. The airbag system includes a spring disposed at the first end. The spring is disposed between the carrier and the base. Upon application of a force to the carrier, e.g., via the tether when the airbag is inflated, the carrier is released from the base and compresses the spring. Upon removal of the force, the spring urges the carrier toward the second end where the carrier is ejected.

The purpose of the present invention is to provide a base fabric for an airbag and an airbag wherein the strength of sewn parts is high, pressure resistance is superior for an airbag during high-pressure deployment at high speeds, and pressure resistance can be maintained even after passage of time in heat. This base fabric for an airbag is characterized by being formed from woven polyamide fibers, and the retention of sewn part strength in the base fabric with heating before and after heat treatment for 400 hours at 140 C. being 70% or greater.

An airbag for a vehicle includes a top, a bottom, a first panel, and a second panel spaced from the first panel. The airbag includes a first leg, a second leg, and a middle leg. The first leg extends from the first panel in a rearward direction. The second leg extends from the second panel in the rearward direction. The middle leg extends from the first panel and the second panel in the rearward direction. The first panel and the second panel each slant in the rearward direction along a direction from the top to the bottom of the airbag. The first panel and the second panel of the airbag in the inflated position may urge occupants to remain upright during an impact event, reducing loading on a chest of the occupants from seat belt.

Disclosed is a method for manufacturing a polyester fabric for an airbag that can not only prevent or minimize the separation of a sizing agent, which is provided to a yarn through a sizing process, during a weaving process, but can also maximize a peel strength between a textile substrate and a coating layer to be subsequently formed thereon and lower the stiffness of an airbag fabric by effectively removing the sizing agent from the textile substrate after the weaving process is completed. The method of the present invention comprises: applying a polyester-based sizing agent to a polyester yarn; manufacturing a textile substrate with the sizing agent-applied polyester yarn; removing the sizing agent from the textile substrate under an alkaline condition of pH 8 to 10; and forming a coating layer on the sizing agent-removed textile substrate in order to enhance air-tightness.
