PROBLEM TO BE SOLVED: To reduce the residual quantity of air during contraction of an air bag by shortening time required for the contraction of the air bag.SOLUTION: In an air bag 60 for being housed inside a seat, a rubber sheet 74 is arranged along a surface of a bag body 107 internally filled with air for expansion. The air infilled into the bag body is discharged depending on an elastic force of the rubber sheet 74. Thus, time required for contraction of the air bag can be shortened, and the residual quantity of the air during the contraction of the air bag can become small. |
