The purpose of the present invention pertains to a coated fabric used for an automotive airbag, and more particularly, a coated fabric for an airbag most suitable for a rollover curtain airbag which is produced applying a sealing agent to a coated fabric and sewing the resulting fabric and which can keep the adhesion of the sealing agent to the coat resin even after long-term and high-temperature aging. The present coated fabric for an airbag is obtained by applying an addition-polymerizable solvent-free silicone resin onto at least one surface of a synthetic fiber textile, wherein a coating amount of the silicone resin is 15 to 45 g/m; and a weft strain/warp strain ratio as observed in stretching the coated fabric is 0.30 to 0.65.

Coated fabric for airbag

To provide a net-like structure having excellent low resilience characteristics, cushioning properties, and durability. The net-like structure has a three-dimensional random loop bonded structure constituted of a continuous linear body made of a thermoplastic elastomer having a fiber diameter of 0.1-3.0 mm and a styrene content of 10-40 mass %, the net-like structure having an apparent density of 0.005-0.30 g/cmand a 40&#xb0; C. compression residual strain of less than or equal to 35%.

Net-like structure having excellent low resilience characteristics

The disclosure describes an air bag having a mechanical characteristic durable against the gas of high output and high temperature generated from an inflator, while reducing amount of the gas leaked from a sewn part of the air bag. The air bag can be used for vehicles and includes a main body part consisting of a base fabric and a sewn part being formed by sewing, with a sewing thread, the main body part into a bag, wherein a difference between an elongation of the sewing thread upon applying a tension of 31.3/a (N/thread) to the sewing thread and an elongation of the base fabric upon applying a tension of 62.5/a to the base fabric (N/stitch), wherein 'a' (stitch(es)/cm) is a sewing pitch in the sewn part, is within a range of 0 to 5.0% in both directions of warp and weft, and an air permeability of the sewn part at 40 kPa during an initial stage of development of the air bag is less than 50 mm/cm/sec.
