Bag suitable for use in an air bag apparatus and method of manufacturing the same

摘要

A bag expandable when an air bag apparatus is activated. A single continuous strap member is alternately sewn on upper and lower fabrics so as to define a plurality of chambers in the bag comprised of the upper and lower fabrics along a predetermined direction. Thus, the single strap member may be successively sewn on the upper and lower fabrics over a range from one end of the strap member to the other end thereof, with the result that the manufacturing cost of the bag can be reduced.
