<p>In an air bag (2), with respect to the distance from a sewed portion (10) to a right outer periphery (13A) of a press-down plate (13), L1 is set less than L2, with L2 being the distance on the installation-side base cloth (3) side, L1 the distance on the cloth-like piece (9) side. When the air bag (2) is inflated in an emergency, the installation-side base cloth (3) side is inflated outward, separating away from the cloth-like piece (9). This opens a gas discharge hole (8), buffering rapid inflation of the air bag (2) toward the occupant side. When the air bag (2) is in a size sufficient to protect the occupant, an engagement plate (17) is instantly bent to release engagement made by the cloth-like piece (9). Then the cloth-like piece (9) comes into tight contact with the installation-side base cloth (3) to close the gas discharge hole (8), reliably protecting the occupant.</p> |
