Abstract: The invention provides a seatbelt retractor comprising at least: a spool for taking up a seatbelt, a lock mechanism having a locking member whereby rotation in the direction of extracting the seatbelt is obstructed in the event of an emergency, a torsion bar rotatably linking the spool and the locking member, and capable of being deformed by twisting and a seatbelt load restricting mechanism for restricting the load placed upon the seatbelt. The torsion bar deforms by twisting at the time that the rotation of the locking member in the direction of the seatbelt being extracted is obstructed. The spool rotates relative to the extraction direction of the seatbelt. The restriction load properties of the seatbelt load restricting mechanism comprise a relatively small restriction load due to twisting deformation of the torsion bar alone, and a relatively great restriction load made up of a restriction load due to twisting deformation of the torsion bar and a restriction load due to another member.

Abstract: In a seat belt retractor, as the rotation of a pawl holder of a locking member in the webbing unwinding direction is stopped by a locking mechanism in emergency, a reel receives a force on a protrusion by impact load applied to the webbing with the inertia of an occupant. As the force is increased, the protrusion is plastically deformed. By this plastic deformation, the impact on the occupant can be greatly absorbed at first. After the protrusion is sheared, the reel tends to rotate in the webbing unwinding direction by the inertia of the occupant, so that the torsion bar is further twisted. Thus, the load can be variously set to effectively absorb kinetic energy of the occupant.
