り成る。2. Description of the Related Art In recent years, airbag devices have been put to practical use as vehicle safety devices. The airbag device is a sensor that detects sudden deceleration such as a vehicle collision, a diagnostic circuit that determines whether or not to deploy the bag based on a signal from the sensor, and an inflator that receives a signal from the diagnostic circuit and generates a high-pressure gas. And airbags that are deployed by high-pressure gas from the inflator to reduce the impact of occupants.

性、難燃性、空気遮蔽性等を向上するためである。There are various types of airbag fabrics.
For example, there is a fabric in which a high-strength long-fiber woven fabric such as nylon is coated with a heat-resistant elastomer (chloroprene rubber, silicone rubber, or the like). The reason why the heat-resistant elastomer is coated is to improve heat resistance, flame retardancy, air-shielding properties, etc., which are insufficient with nylon fabric alone.

る等の問題点を有していた。[0004] However, the coating has a problem that the bag is heavy and hard and hard to fold, and the cost of the bag is high. With the demand for smaller, lighter, more flexible, easier folding, and lower cost bags, and the inflators becoming smaller, non-coated fabrics are becoming more common. However, non-coated fabrics of conventional woven density have poor air shielding properties, and when the bag is deployed,
High-pressure gas from the inflator leaks to the occupant.
Therefore, the air shielding property is improved by increasing the weaving density of the cloth. However, when the weaving density is increased, there is a problem that the cloth becomes hard and the basis weight increases.
