り成る。2. Description of the Related Art In recent years, an airbag device has been put into practical use as a vehicle safety device. An airbag device is a sensor that detects a sudden deceleration such as a collision of a vehicle, a diagnostic circuit that determines whether to deploy a bag based on a signal from the sensor, an inflator that generates a high-pressure gas by receiving a signal from the diagnostic circuit. , An airbag that is deployed by high-pressure gas from the inflator to absorb the impact of the occupant.

性、難燃性、空気遮蔽性等を向上するためである。Although there are various modes of fabric for airbags,
For example, there is a cloth obtained by coating a high-strength long fiber woven fabric such as nylon with a heat resistant elastomer (chloroprene rubber, silicone rubber, etc.). The reason why the heat-resistant elastomer is coated is to improve heat resistance, flame retardancy, air-shielding property, etc., which are insufficient with nylon cloth.

る等の問題点を有していた。However, the coating causes problems such that the bag becomes heavy and hard, is difficult to fold, and the cost of the bag is high. With the demand for smaller and lighter bags, flexibility, easier folding, and cost reduction, and with the size reduction of inflators, non-coating of fabrics has been advanced. However, conventional non-coated cloth with woven density has poor air-shielding properties, and when the bag is deployed,
High-pressure gas from the inflator leaks to the passenger side.
Therefore, the woven density of the cloth is increased to improve the air-shielding property. However, when the woven density is increased, there is a problem that the cloth becomes hard and the basis weight becomes large.

Particularly, the air permeability is lowered irrespective of the coating, and the cost is low, the weight is light, the foldability is good, and the vehicle air bag is used. It is to provide a fabric.

It should be at least g / denier. Weaving density is 40 with both history
It should be between 60 and 60 lines / inch. Considering the physical properties of the base fabric required for airbag fabrics, it is preferable to use a yarn having a single yarn denier of 6 denier and a total denier of 420 denier, a yarn strength of 8 g / denier or more, and a weaving density of the weft density. Both are preferably 45 to 55 pieces / inch. Weave density is 60
If the number is more than 1 line / inch, the fabric becomes too hard, and if less than 40 lines / inch, the air permeability is too large.
