PROBLEM TO BE SOLVED: To smoothly expand an air bag body even in the case of an occupant being positioned close to the side part of a cabin. SOLUTION: A part, arranged along a C-pillar 20 and a roof side rail 48, of an air bag body 16 is formed as a gas introducing passage 50 for feeding gas into each of expansion chambers 36, 34, 32, 30, 28, 26, 24. Openings 36A, 34A, 32A, 30A, 28A, 26A, 24A communicated with the gas introducing passage 50 are formed at the upper parts of the respective expansion chambers. The openings 30A, 34A, 36A for feeding gas to the expansion chambers 30, 34, 36 in an area overlapped with a B-pillar 18 and the C-pillar 20 are set larger than the openings 24A, 26A, 28A, 32A for feeding gas to the other expansion chambers 24, 26, 28, 32. |
