Provided is an air bag base cloth constituted by a composite material obtained by coating fabric made of synthetic fibers with a synthetic resin. The average value of the 100% modulus in the warp direction of the fabric texture included in the composite material and the 100% modulus in the weft direction of the fabric texture included in the composite material is 50 N/cm or less. The 100% elongation recovery rate is 95% or more. The 100% elongation load air permeability is 0.1 L/cm.sup.2.Math.min or less both before and after thermal treatment at 100 C.

In one example, an apparatus for helping to protect an occupant of a vehicle includes an inflatable vehicle occupant protection device having a deflated condition and an inflated condition. The protection device includes a first panel having a centerline and first and second openings. A second panel is secured to the first panel to define an inflatable volume. First and second self-adaptive vents are secured to the first panel over the first and second openings on opposite sides of the centerline for selectively releasing inflation fluid from the inflatable volume in response to penetration of the occupant into the protection device. A first reinforcing stitching extends through the first panel and around a portion of the first self-adaptive vent. A second reinforcing stitching extends through the first panel and around a portion of the second self-adaptive vent. Each of the first and second reinforcing stitchings is spaced entirely from the respective first and second self-adaptive vents.

An air bag cushion for a vehicle. A tether reinforcing fabric coupled to a tether seam portion of a main cushion is used to allow the tether reinforcing fabric to inflate with the main cushion when the main cushion inflates, and the inflating tether reinforcing fabric forms an auxiliary chamber between the main cushion and the tether reinforcing fabric, and the auxiliary chamber of the tether reinforcing fabric supports the head of a passenger in a front passenger seat in the event of a crash, thereby preventing the rotation of the passenger's head and efficiently protecting the safety of the front passenger.

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.

A head-protecting airbag device includes: an airbag body; and a connecting piece which is formed of a sheet material with flexibility, wherein: the airbag body and the connecting piece constitute an airbag having a bag shape inflatable to cover an inboard side of a window of a vehicle; the airbag body includes an inboard side wall disposed on the inboard side at the time of inflation completion, an outboard side wall disposed on an outboard side, and a coupling target portion coupling the connecting piece; the coupling target portion is configured to be divided into an inboard side portion and an outboard side portion; and the root end of the connecting piece is nipped between the inboard side portion and the outboard side portion, and is coupled with the inboard side portion and the outboard side portion so as to be connected with the airbag body.

A restraint system includes an inflator, an airbag inflatable by the inflator and having an exterior surface, and a fabric tunnel attached on the exterior surface of the airbag and elongated from a sealed end to an open end. The tunnel is fluidly isolated from the inflator. The tunnel is oriented relative to the airbag so that the open end is aimed in a direction of motion during inflation of the airbag.

The invention relates to an airbag (12) for an automotive vehicle (10) comprising an airbag fabric (24) forming at least one airbag wall (26, 28) and an elongate flexible tether (20) for positioning the airbag (12) in its deployed state which extends from a first tether end (30) associated with the airbag fabric (24) to an opposite second tether end (32), wherein at the first tether end (30) the tether (20) is tightly sewn to the airbag fabric (24) by a fastening seam (36) and wherein the airbag fabric (24) includes a fabric reinforcing seam (38) which encloses at least part of the fastening seam (36). The invention further relates to a method of mounting a tether (20) on the airbag fabric (24).

Airbag cushion diffusers comprising one or more frangible portions and related airbag cushion assemblies and methods. In some embodiments, an airbag cushion assembly may comprise an airbag cushion having an internal diffuser positioned therein. The internal diffuser may comprise a lower panel that may be sewn or otherwise directly coupled to the airbag cushion and an upper panel coupled to the lower panel about respective entire peripheries of the upper and lower panels so as to define a diffuser chamber between the upper panel and the lower panel. The upper panel may comprise a plurality of openings for delivery of inflation gas therethrough and may comprise one or more openings, slits, and/or weakened regions configured to facilitate tearing in specific locations of the diffuser.

Provided is a seam-sealed curtain airbag cushion that makes a panel with a fabric to which a silicone coating liquid is applied and doubly couples a first panel and a second panel constituting the panel by means of a silicone sealant and a sewing yarn so as to maintain the internal pressure thereof for a period of time in the event of a side crush or vehicle overturning. The seam-sealed curtain airbag cushion has the improvements in the tensile strength and tearing strength and is not deteriorated in performance even under various external environments.

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.
