An airbag for a front passenger seat, comprising: an inlet port for inflation gas; a main body, formed of at least one panel of fabric, and comprising a retainer (3) adapted for mounting the airbag to a vehicle, and a passenger contact region; and at least one tether (4) located inside the main body and connecting the retainer (3) to the passenger contact region so as to restrain inflation of at least a portion of the passenger contact region, wherein the tether (4) is attached to the fabric panel along a generally vertical line by stitches (7) which pass through stitch holes which are located inside the main body.

A side airbag apparatus including a cushion sheet part having a first insertion slot part and first stud hole parts; a pocket sheet part having a second insertion slot part and second stud hole parts to correspond to the first insertion slot part and the first stud hole parts, respectively, and superposed on the cushion sheet part; partition sheet parts superposed on the cushion sheet part so as to be connected to both sides of the pocket sheet part; first sewing parts that connect the partition sheet parts and the pocket sheet part to the cushion sheet part; a second sewing part that connects superposed ends of the pocket sheet part and partition sheet parts that are folded in half; and a third sewing part that connects superposed circumferential portions of the cushion sheet part after the cushion sheet part is folded on the basis of a center portion thereof.

An apparatus for helping to protect an occupant of a seat in a vehicle having an instrument panel and a housing positioned therein includes an airbag for positioning in the housing and defining an inflatable volume for receiving inflation fluid from an inflator. The airbag includes an occupant-facing panel. A tether extends along a centerline and has a first end connected to a portion of the airbag positioned within the housing and a second end connected to the occupant-facing panel for forming a pocket therein. The second end includes a folded-over portion. Stitching extends through the folded-over portion in a direction extending transverse to the centerline.

A non-coated air bag base cloth of the present invention is constituted by a fabric formed using a yarn containing polyethylene terephthalate as a main raw material, in which a single fiber strength of a yarn of the fabric is 7.30 to 8.50 cN, a single fiber fineness of a yarn of the fabric is 1.6 to 3.9 dtex, and a cover factor is 2400 to 2800.

An airbag device, including: a gas generator that generates expansion gas; an airbag that expands and deploys by the expansion gas to restrain an occupant; and a gas rectifying member provided inside the airbag so as to cover the occupant side of the gas generator, and that controls the flow of the expansion gas. The gas rectifying member is formed from a flat panel including a portion bilaterally symmetrical to a line connecting 12 o'clock and 6 o'clock (X axis) when a plane parallel to a rim of the steering wheel is regarded as a clock face, and has a configuration where a lower opening portion for discharging the expansion gas in a 6 o'clock direction is formed by stitching left and right edge portions of the panel together, and the occupant side of the gas generator is covered.

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.

A curtain airbag attached to a vehicle body and expanded and deployed by a gas from an inflator containing: a first region along a lower edge; a second region adjacent above the first region with a first fold line; a third region adjacent above the second region with a second fold line formed on an opposite side of the first fold line across the second region. The first region is in a condition folded back at the first fold line to face a first surface side of the second region, the second region is in a condition folded back at the second fold line such that the folded back first region is between the second region and the third region, the third region is in a condition rolled upward on a second surface side. Rolling starts from the second fold line.

A vehicle airbag device and a method for manufacturing the same, in which stud bolts for securing the device to the vehicle body can be inserted avoiding the sewn sections, and in which unbalanced stresses are not generated in the panel parts during expansion and deployment.

The device having a pair of panel parts, a pair of expansion parts integrally provided on the pair of panel parts, the expansion part of the first panel part overlapping the second panel part, and the expansion part of the second panel part overlapping the first panel part, forming an overlapping section by joining each expansion part to each panel part at a sewn section, and joining the overlapping section with a pair of panel part outer edges, the outer sewn section forming a hollow bag body, and providing inflator insertion holes and bolt insertion holes provided through the overlapping section.

An airbag cushion according to an embodiment may include a main body including a rear panel having a rear bonding line and a front panel having a front bonding line bonded to the rear bonding line and disposed to face a passenger when inflated by a gas introduced into an inner space formed between the front panel and the rear panel and a protruding chamber which is inflated and protrudes toward the passenger from the front panel, wherein the protruding chamber is provided with a folding structure in a state in which a part of the front panel is folded, and the folding structure is unfolded and inflated as the main body is inflated by the gas introduced into the inner space.

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.
