<p>PROBLEM TO BE SOLVED: To provide a seat belt device for obtaining a characteristic approximate to a desired webbing extension characteristic. SOLUTION: When webbing extends by being pulled at collision time, plural deforming members are deformed by successively applying a load of the webbing, and a load-extension characteristic of the webbing changes stepwise (in a step shape). A construction material of the deforming members is properly changed so as to approach a desired extension characteristic.</p> |
