Abstract
An air bag which has a bag body which has a plurality of chambers with respective check valves, an air passage which is located on an upper portion of the body and which communicates with the check valves, and an inlet part which is fitted in the air passage. The inlet part is a double-folded plastic film and is fitted between a front film and a back film which compose the bag body and the air passage. An injection nozzle is inserted in the inlet part. When the tip of the nozzle comes in contact with the turnaround portion of the double-folded film, the injection nozzle automatically blows out air, and the air flows from the air passage into the chambers through the check valves.
