Abstract
In an air bag system according to the invention, there is employed a control device which can control the internal pressure of an air bag after expanded in such a manner that a buffer distance, for which the air bag after expanded can be compressed when it is contacted with an occupant, can be kept constant regardless of an increase or a decrease in the weight or the like of the occupant. In operation, the control device firstly takes out the acceleration data of the occupant corresponding to the degree of a collision in accordance with a signal from an acceleration sensor. Next, in accordance with the thus taken-out acceleration, a distance from the air bag before expanded to the head and bosom portion of the occupant obtained based on a signal from a distance sensor, and the weight of the occupant head and bosom portion obtained based on a signal from a weight sensor, the control device calculates a proper value of the internal pressure of the air bag according to a velocity/distance/power balancing condition equation, and controls a gas generation device in such a manner it can produce a generated gas pressure corresponding to the thus calculated proper value.
