Abstract
An air bag system in which a small quantity of gas is necessary for quickly unfolding the air bag, is disclosed. The air bag system has a housing having a cover at the upper portion thereof and an inflator for generating inert gas. The inflator being provided at the bottom portion of said housing and is filled therein with an explosive material for generating the inert gas by igniting the explosive material when a collision sensing signal which is generated at the collision of the motor vehicle. An inflatable air bag is folded in said housing and has a front portion which contacts with a human body when unfolded, an inlet portion for introducing the inert gas into said inflatable air bag, a middle portion between the front portion and the inlet portion. The front portion has a flexible foam coated on an outer surface of the front portion. Thus, the air bag can be fully unfolded by using only a small quantity of the gas, thereby reducing the amount of the igniting agent and the gas generation material. An unfolding force can be obtained regardless of the air bag sizes and the amount of the expanding gas having a hot temperature and high pressure. The danger of being burned and the secondary shock due to the unfolding of the air bag may be removed.
