PROBLEM TO BE SOLVED: To provide a colliding object advancing direction monitoring system capable of taking a measure against a collision in the early stages of a collision accident by previously sensing the collision accident, and a collision safety device for a two-wheeler using this monitoring system. SOLUTION: The collision safety device 1 for the two-wheeler has an air jacket 2, a cartridge 3, and an opening device 4. This colliding object advancing direction monitoring system for the two-wheeler 5 outputs a control signal when satisfying a first condition of becoming a prescribed distance on an interval L between the two-wheeler and an obstacle before the traveling two-wheeler collides with the obstacle 6 existing in front and a second condition of becoming a prescribed value or more in the direction for approaching the obstacle on a relative speed ΔV of the two-wheeler to the obstacle, and operates the opening device. At this time, a sealing plate 12 of the cartridge is opened, and the filled high pressure gas flows in an air sac 11 of the air jacket, and inflates the air sac, and protects a rider of the two-wheeler. |
