Claims

[Scope of utility model registration request]

A preloader that applies a retraction load to the seatbelt to eliminate slack when the seatbelt is locked, includes a seatbelt retraction member having one end attached to the seatbelt near an extension from the retractor, and one end attached to the retractor. a spring whose other end is respectively locked to the other end of the seat belt retracting member to generate a retracting load for the seat belt; and a spring interposed between the retractor and the other end of the belt retracting member to generate a belt retracting load. a stopper mechanism that holds the lock mechanism in an inoperative position when the seat belt is unlocked; and an actuator that releases the stopper mechanism and operates the lock mechanism when the seat belt is locked. A preloader characterized by:
