a plurality of sheets of cloth. The expansion of the air bag and the final shape depend strongly on the inner pressure and the shape of the plurality of sheets of cloth rather than the external force. Especially, the final shape of the air bag is determined based on the initial shape.
The effort to make the final shape good is shown in FIG. 3. In the air bag apparatus for side crash shown in FIG. 3, by limiting the expansion width W in the direction perpendicular to the side surface of the air bag 105 within a predetermined value, the shape on the expansion way is controlled. To make such limitation effective, an inner forming section (an inner side panel) 106 of the air bag and an outerEarlier this month we presented some of the breathtaking entries into the People category of the 2018 National Geographic Travel Photographer of the Year Contest.
