Airbag and its wrapping method

An airbag comprising:

• an airbag body,
• wherein said airbag body is folded for being housed on a peripheral edge of an opening on an inner portion of a car body, the airbag body being folded up into a rod-like shape and being inflatable upon inflow of inflating gas for covering said opening;
• and
• a wrapping member made tearable for preventing said airbag body from unfolding prior to inflation, the folded airbag body being wrapped with said wrapping member around an outer periphery of the folded airbag body,
• wherein said wrapping member is made of a flexible long member and wrapped around the outer periphery of said folded airbag body substantially all along a length of the folded airbag body, so that the wrapping member may extend along the axial direction of said airbag body folded up into the rod-like shape obliquely to said axial direction,
• wherein said wrapping member includes a plurality of wrapping members wrapped around the outer periphery of said folded airbag body so as to overlap with each other at intersections of the plurality members, the plurality of wrapping members being wrapped around the air bag body from opposite directions to create the intersections.
