19. An air bag for an air bag system to be mounted on a vehicle for protecting a passenger and having an inflator, comprising:
-
an air-impermeable cloth disposed at a side facing the passenger when inflated, an air-permeable cloth disposed at a side of the vehicle when inflated, said air-permeable cloth being connected to the air-impermeable cloth to constitute the air bag and having an opening in a center thereof, gas from the inflator being ejected into the air bag through the opening, and a free member made of a material to restrict air passing therethrough, said free member being connected to the air-permeable cloth around the opening thereof and located inside the air bag to be placed over the air-permeable cloth so that when the inflator is actuated upon detection of a predetermined acceleration, the air bag is inflated by gas ejected from the inflater and air inhaled through the air permeable cloth while the free member is moved away from the air-permeable cloth to allow air to pass through the air-permeable cloth, and when the passenger hits the inflated air bag, the free member inside the air bag is disposed on the air-permeable cloth to partly prevent air and gas inside the air bag from escaping from the air bag to thereby control passage of air into and from the air bag.
