Patent number: 9878684Abstract: The present invention addresses the problem of providing a cloth which, when used as an air bag main body cloth, does not undergo the damage caused by a high-temperature gas generated from an inflater, and therefore has high heat resistance and is suitable for an air bag. The means for solving the problem is a coated cloth for an air bag, which is produced by applying an elastomer resin layer on at least one surface of a three-dimensional woven fabric in an amount of 50 to 500 g/m2 per one surface, said coated cloth being characterized by having void spaces formed therein, wherein the void content in the coated cloth is 15 to 60%. Preferably, the coated cloth is used in applications in which the coated cloth is attached onto the periphery of an inflater connection opening in an air bag.Type: GrantFiled: August 26, 2013Date of Patent: January 30, 2018Assignee: TORAY INDUSTRIES, INC.Inventors: Nobuaki Tanaka, Hiroshi Tsuchikura, Satoshi Yamada
