Patent number: 6471238Abstract: An air-bag 12 is designed to vertically expand after transversely expanding while being inflated. The air-bag 12 having a substantially circular shape is folded from its opposite ends toward its middle along a direction “a” corresponding to vertical direction and rolled in an opposite direction, is then folded in a zigzag manner one fold over another from its opposite ends toward its middle along a direction “b” (transverse direction), and is accommodated in a container casing 14. Accordingly, the inventive air-bag device and air-bag folding method can suppress an inflation (expansion) of the air-bag toward a passenger at an early stage of the inflation of the air-bag, promote a transverse expansion more than a vertical expansion of the air-bag at the early stage of the inflation, and prevent a blow out of a gas toward the passenger.Type: GrantFiled: April 4, 2000Date of Patent: October 29, 2002Assignees: Mazda Motor Corporation, Ashimori Kogyo Kabushiki KaishaInventors: Toshihiro Ishikawa, Takeshi Takagi, Kazunori Etou, Akinori Koyama, Kouichi Ishida
