An air bag system is provided which includes an inflator serving as a gas generator, an air bag which is stored in a folded state in a certain portion of a vehicle and is adapted to be inflated by the gas supplied from the inflator to protect a vehicle occupant or occupants, and a diffuser serving to guide gas from the inflator into the air bag. In the air bag system, a preliminary inflatable portion is formed in a gas supply port of the air bag and a gas distribution portion formed in the end of the diffuser is arranged within the preliminary inflatable portion.
