PROBLEM TO BE SOLVED: To make small time differences among inflation times in respective parts of a bag, and to attain quick inflation as the whole. SOLUTION: In this bag 1, sheets are overlapped and are coupled in their peripheral edge parts to form a main gas passage and small chambers 8a-8k between the both sheets. The main gas passage is extended linearly from a lower end of a front edge part 1F in the bag 1 to a rear end of its upper edge part 1U. Gas from an inflator 30 inflates at first the main gas passage straight- rod-likely to develop the bag 1 curtain-likely, and then the gas flows from the main gas passage into the respective small chambers 8a-8k via a gas inlet 12 to inflate the chambers 8a-8k. |
