1. An air bag system comprising:

  • a retainer, a folded air bag supported on the retainer, an inflator supported on the retainer, the air bag being inflated to be deployed into a passenger compartment of a vehicle by a gas produced by the inflator at the time of collision, and a restricting member including a restricting fabric disposed along an outer surface of the air bag, and a brittle portion on the restricting member, wherein, an end portion of the restricting member is coupled to the retainer, so that in an earlier stage of deployment of the air bag, an axial inflation of the air bag is restricted by the restricting member, and in a later stage of deployment of the air bag, the brittle portion is broken by a tension so as to allow the air bag to inflate to its maximum capacity, and the restricting member closes a vent hole formed in the air bag until the brittle portion on the restricting member is broken, and the vent hole is opened when the brittle portion is broken.
