Abstract: Disclosed is a curtain bag that can obtain a necessary inflated state in a short period of time without applying excessive localized force to a peripheral joining section or an inner joining section, and that is improved in the ability to suppress the ejection of passengers out from a vehicle specifically by a lateral collision. A portion of the curtain bag and/or the peripheral edge is shaped so as to snag the bottom sill of a window, and the inner joining section of the region that contacts the section below the bottom sill of the window is shaped with a plurality of dots and/or given an expandable form across effectively the entire surface and/or given a form that has increased bending stiffness.

Abstract: Provided is a curtain bag which can be brought into an inflated state as required in a short time without locally applying an excessive load to its outer peripheral joint part (1) and inner joint parts (2). The dot-like inner joint parts (2) on the inside of the outer peripheral joint part (1) are isolated from the outer peripheral joint part (1) and also made to be independent of each other.

Abstract: An air bag which is light and pliable to be compactly housed and excellent in durability against a load applied thereto, upon the actuation of air bag, and long term aging, which is formed of two woven fabrics interwoven with each other to be a bag-shaped body, each composed of polyamide type synthetic fiber yarns containing copper compounds in a range from 30 to 200 ppm estimated in term of copper or cut pieces of the fabric sewn together to be a three-dimensional shape, the fabric having a product of a total fineness of warp or weft multiplied by a weave density of 16000 decitex·ends/2.54 cm or less, a load at 15% elongation in a range from 3 to 35 N/%/2.54 cm and a tensile work at break in a range from 7000 to 30000 N·%/2.54 cm. This air bag may be applicable to a driver's seat, a passenger's seat, and to side impact protection in a vehicle.

Abstract: An object is to provide an air bag to protect passengers during collisions, which is lighter and can be compactly accommodated, which is sufficiently airtight, and which has durable strength in the sewn parts. The invention relates to a lightweight air bag, wherein the air bag main body is constituted of a base fabric composed of a woven fabric which has been made using a raw yarn of less than 150 denier and a cover factor of 2100 or more or a basis weight of 140 g/m2 or less, and the air bag main body is preferably constituted of a base fabric having 10 g/m2 or less of a heat resistant elastomer applied thereon, at least part of the sewn areas relating to the air bag main body, particularly where a reinforcing fabric is sewn around the inflator fitting hole, being sewn with a sewing thread having a specific yarn number count T and stitch number S (stitches/centimeter), as indicated by the following Formulas: 10<T≦60  (1A) 2≦T/S≦8  (1B)(1).

Abstract: An air bag having improved characteristics of preventing rebounding, a light weight and a lower price, wherein a bag-like body having an opening for attaching a gas generator is manufactured by joining circumferential portions of at least two woven fabrics, a coating film is partially provided on a surface of the bag-like body to reinforce the bag-like body and prevent injury to a passenger, and an exhausting portion is provided by suitably determining an area where the coating film is not provided according to an air permeability of the woven fabric. A further improvement of the performance and a cost reduction of the air bag can be obtained by forming the joining portion with a binding-to-one layer weave.
