In a side impact air bag system, a bag is formed of a main body opposing an abdomen portion of a passenger and an upper inflation unit opposing a chest portion of the passenger, a tip portion in the longitudinal direction of the upper inflation unit is deleted and a connection of a gas intake portion to an inflator is shortened to reduce a length of the upper inflation unit than the length of the main body. This reduces the length of the upper inflation unit to be shorter than the main body when the bag is inflated to relax the shock to the chest portion of the passenger when the bag is inflated, thereby positively inflating the bag in the narrow space between the vehicle body and the passenger's seat without excessively increasing the shock to the chest portion of the passenger.
