PURPOSE: To prevent injury from inflicting on the human body by providing an energy absorption unit with high safety and a high-performance shock energy absorption ability, reducing its size and weight, and uniformalizing the shock acting on the human body in absorbing the shock energy. CONSTITUTION: This is an energy absorption unit 30 which is constituted of the first belt part 22 with the first width (d), and the second belt part 23 with the second width (D) which is larger than the first width (d) of the first belt body 22. The energy absorption unit 30 is so formed that the first belt part 22 plus the second belt part 23, and the first part 28 in a separated state plus the second part 27 which is in such a state that the second belt part 23 substantially encircles the first belt part 22 so as to be integrally fixed with each other are arranged in the adjacent. |
