摘要： A seat belt retractor configured to prevent the occurrence of backlash between the torsion bar and a member to which the same is fitted even when a force is applied to the torsion bar when rotation of the retractor is locked. Backlash preventing ribs are provided on the inner peripheral surfaces of the axial hole of the reel on the sides which not subject to a large force between the reel and the torsion bar. Therefore, since a large force generated when rotation of the locking base of the locking mechanism in the webbing unwinding direction is locked is not applied to these backlash preventing ribs the collapse of the backlash preventing ribs caused by such a force can be prevented.

摘要： A seat belt retractor which achieves stable performance of a pretensioner. The seat belt retractor includes a spool for winding up a belt thereon. The spool has a shaft portion, a spool gear, and a spring-biased shaft projection which are disposed to project from a face of the spool. A spool bearing (or ring-like collar) is fitted around the shaft portion of the spool. The spool bearing is made of a material having high hardness and high rigidity such as SUS or SC. By this spool bearing, the spool is prevented from being directly subjected to load, like a bearing.

摘要： A seat belt retractor having a structure preventing a gear or pinion having external teeth from being improperly assembled to a spool gear. The pinion includes concave portions on its inner periphery and the spool gear includes corresponding convex portions on its outer periphery. The concave and convex portions are configured to be fit together may be inclined in the circumferential direction and thus have no symmetrical plane. If during assembly the pinion is positioned adjacent the spool gear with the wrong side out, the pinion and the spool gear would not fit together and the mistake would be noticed and, therefore, prevented.

摘要： A seat belt retractor including a torsion bar is provided. A second torque transmitting portion of the torsion bar is clamped between a reel and a holder member press-fitted radially in the reel without backlash in the axial direction. A first torque transmitting portion is strictly fixed to a pawl holder without backlash in the axial direction by radially crimping an internal periphery of a left end portion of the pawl holder of a locking means. Therefore, the first and second torque transmitting portions conventionally formed in a torsion bar are effectively used, thereby eliminating a groove for an E-ring as conventionally used and thus simplifying the configuration of the torsion bar. In addition, since the first and second torque transmitting portions can operate without backlash, the occurrence of jarring noise due to vibrations of the seat belt retractor can be prevented.

摘要： A seat belt retractor with a torsion bar which can receive a large torque and can be easily formed by forging is provided. A reel assembly of the seat belt retractor includes a reel, a torsion bar, and a locking member. A first connection part of the torsion bar non-rotatably couples with concavities of a locking base of the locking member. A second connection part non-rotatably couples with concavities of the reel. The outer peripheries of the connection parts and are torx-shaped having a plurality of concavities and convexities formed in a wave-shape. A ratio R1/R2 of the distance between the tops of the wave-shaped convexities of the connection parts and the axial center of the torsion bar (radius R1) to the distance between the bottoms of the concavities and the axial center of the torsion bar (radius R2) is set to 1.2 to 1.3.

摘要： In an emergency situation, a pretensioner is activated so that a spool and a locking base are quickly rotated together in a belt-retracting direction. Subsequently, a stopper is guided along a guide groove so as to move (rotate) counterclockwise relatively with respect to the locking base, thereby reaching an active position. Accordingly, the stopper is released from a latching claw, and a quick-lock pawl is rotated clockwise with a biasing force of a spring, whereby the latching claw becomes engaged with internal teeth. Thus, the locking base becomes locked so that the locking base is prevented from rotating in the belt-withdrawing direction, and the EA operation by the torsion bar is quickly performed.

摘要： A seatbelt retractor including a spool including a first spool component for retracting the seatbelt and a second spool component to which a driving force of a pretensioner is transmitted. When the relative rotational torque reaches a predetermined value or more, a member linking the spool components is subject to bending deformation and tensile deformation so that the first spool component rotates relatively with respect to the second spool component in a belt-withdrawing direction. As a result, the spool rotates in a belt-retracting direction so that a torsion bar becomes twisted, whereby impact energy is absorbed.
