PROBLEM TO BE SOLVED: To deploy an air bag into a desired shape even when the upper section of the air bag is located at a position to interfere with a belt member by providing a lock prohibiting means preventing a retractor from being set to the lock state when a side collision load is sensed. SOLUTION: A belt member 2 is fitted to an occupant like the normal seat belt device. When acceleration/deceleration of the prescribed value or above is applied to a vehicle at the time of a head-on collision, a retractor 6 is switched to the lock state, the delivery of the belt member 2 is blocked, and the occupant is constrained. A side air bag is deployed when a shock exceeds the prescribed value at the time of a side collision. An operating member 50 is moved to the indoor side by an obstacle 60, and the retractor 6 is prevented from being set to the lock state. The belt member 2 can be delivered, and an air bag can be deployed into the prescribed shape even when the belt member 2 is located at a position to interfere with the upper section of the side air bag. |
