ABSTRACT:
In a side impact air bag system, a first vent hole and a second vent hole for reducing a pressure of a part opposing a chest portion of a passenger to a lower value than the pressure of a part opposing an abdomen portion of the passenger when the bag is inflated. The vent holes are provided on a side surface of an upper inflation unit opposite to the passenger, whereby regulating gas discharge of the part opposing the chest portion while preventing early discharge of the gas, always obtaining a desired internal pressure and inflation condition, positively inflating the bag and relaxing a shock to the chest portion. Further, the first vent hole and the second vent hole are formed at positions not contacting with vehicle compartment structural members, thereby preventing the vent hole and the second vent hole from being closed even when the vehicle compartment structural members are deformed toward the inside of the vehicle compartment, eliminating disturbance to gas discharge when the bag is inflated, and always obtaining the desired internal pressure condition.
