Abstract

Abstract An air bag, formed by sewing two basic fabrics at a sewing portion, is accommodated within a module case in a state in which the air bag has been fixed to a holder of an inflater at rear-side base portions and folded up into a bellows-like shape at a front-side foldable portions. The base portion of the left basic fabric, which is remote from a center pillar and a front door of a vehicle, has a section between two points b and c, which defines a surplus section. When the foldable portions of the air bag are expanded, the foldable portions can be moved toward an inner surface of a side of the vehicle body by the surplus section b and c and hence, the air bag can be deployed obliquely forwardly to reliably penetrate into a space between the center pillar, as well as the front door, and an occupant.
