In a head protection air bag device (12), a folded air bag receives inflation gas, and when its inflating operation is completed, inflation parts of front and rear inflatable protective shielding parts (14,18) as partitioned by partitioning parts (29) generate tensions in the longitudinal direction in the front and rear inflatable protective shielding parts per se. The front and rear inflatable protective shielding parts (14,18) are interconnected to each other by inflation communicating part (23) under a plate-like portion which blocks the inflow of the inflation gas, at the lower fringe side of the air bag (12b). The inflation communication parts (23) are longitudinally disposed along the lower fringe side (12b) of the air bag. Therefore, the front and rear inflatable protective shielding parts (14,18) are interconnected without reducing the tensions in those parts. As a result, a high tension having the longitudinal direction is generated in the entire lower fringe of the air bag. <IMAGE> |
