  • Patent number: 7066490
    Abstract: An airbag device comprises a folded and housed airbag including: a vehicle front-facing wall portion having a gas inlet through which inflating gas can enter; and a passenger-facing wall portion directly opposite the gas inlet port. In the airbag, there is arranged a flow regulating cloth. This flow regulating cloth regulates the inflow of the inflating gas so that the unnecessary protrusion of the passenger-facing wall portion toward the passenger is prevented. Moreover, the flow regulating cloth breaks at a portion made to be easily torn, before the completion of inflation of the airbag. In other words, the airbag is released from the regulation of the inflow of the inflating gas before the completion of inflation.

  • Patent number: 5868660
    Abstract: A method of folding up an air bag comprises the steps of: folding up the horizontally-spread air bag crosswise so as to decrease its width crosswise; extending left and right regions on the center side of the air bag in the outer diagonally-upward direction; folding up both left and right end sides of the air bag in the outer diagonally-downward position of the left and right regions; setting the left and right regions close to the center of the air bag so that the left and right regions are extended upward; and moving both folded end sides to the center of the air bag and outside the left and right regions.
