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.
