An air bag is divided by a partition wall into an upper section and a lower section. When the vehicle occupant is wearing a seat belt, gas is supplied from an inflator only to the upper section, so that the air bag mainly restrains the head of the vehicle while applying a reduced restraining force of the chest of the occupant. When the vehicle occupant is not wearing the seat belt, gas is initially supplied from the inflator to the lower section, until the upper section and the lower section are brought into communication with each other as a result of expansion of the lower section, and then the gas is also led to the upper section, so that the air bag accurately and effectively restrains the head and chest of the vehicle occupant. <IMAGE> |
