<p>PROBLEM TO BE SOLVED: To provide an air bag which can secure adequately comfortableness of a seating person and can be manufactured by a method of high productivity.SOLUTION: An air bag 60 which inflates through air filling to the inside is housed in the inside of a seat. And, shape-specifying members 74, 76 are provided at specified surfaces of the air bag which positions at a seating person side to the seat, and the shapes of the specified surfaces are specified as the shapes along the surfaces of the shape-specifying members. Thus, the shape of the seating surface of a seat which is projected by air bag inflation can be made planar and comfortableness of the seating person can be secured. Further, the air bag can be manufactured by fitting the shape-specifying member to at least one side of two sheets in advance and jointing the two sheets to each other at the edge parts, for example. By means of this, the air bag can be manufactured by a relatively simple method and productivity can be raised.</p> |
