Claims

[Scope of Utility Model Registration Claim] In a seat belt device in which a retractor is attached to a vehicle body panel and a webbing pulled out from the retractor restrains an occupant, tension is applied to the webbing until a predetermined displacement, and after the predetermined displacement, A seat belt device characterized in that an energy absorbing means for making the gradient of increase in the tension of the webbing gentle without sudden changes is provided at the attachment portion of the retractor to the vehicle body panel.
