<p>PROBLEM TO BE SOLVED: To easily form a structure capable of preventing a lid part from being pulled off from a cover by the inflation of an air bag and dispersed into a cabin in a cover structure of an air bag system. SOLUTION: The lid part 8 is formed integrally with the cover 1 of the air bag 21 by using predicted rupture parts 4, 5, and 6, and a rib 9 disposed over the lid part 8 and the cover 1 is formed integrally with the lid part 8 and the cover 1 so as to bridge the predicted rupture parts 4 and 5. When the air bag 21 is inflated, the predicted rupture parts 4, 5, and 6 are broken, and the lid part 8 is open by using the specified portion of the lid part 8 as a hinge portion so as to develop the air bag 21.</p> |
