Abstract
When the airbag portion is inflated, the tip portions of the curtain portion are moved downward and thereby the tension portions connected by the bands are pulled down to the position of the support pins as shown in FIG. 6B. Thus, the tension can be provided to the curtain portion at a portion between the support pins with the length V between the right-side tension portion and the left-side tension portion, which is shorter than the three-side length (X+Y+Z).
