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 torsion bar in a seat belt retractor includes a torsion portion to be twisted. The torsion portion has an outer portion, and a center portion inside the outer portion. The outer portion has a hardness lower than that at the center portion to thereby increase energy absorption in twisting the torsion portion. Therefore, even if higher stress is applied to the outer portion of the torsion portion when the torsion bar is twisted, the number of turns until the torsion bar is broken can be increased as compared to the conventional one. Accordingly, the belt withdrawing amount is ensured enough after the twisting of the torsion portion is started, thereby improving the energy absorbing capacity.
摘要翻译：安全带卷收器中的扭杆包括扭转扭转部。扭转部分具有外部部分和外部部分内部的中心部分。外部部分的硬度低于中心部分的硬度，从而增加扭转扭转部分的能量吸收。因此，即使当扭杆扭转时，在扭转部的外侧施加较高的应力，与现有技术相比，能够增加直到扭杆断裂的匝数。因此，在扭转部的扭转开始后，能够确保带退出量，从而提高能量吸收能力。

摘要： To ensure stable EA operation without being affected by action of a pretensioner.A seat belt retractor comprises a torsion bar 7 of which one end in the axial direction is connected to a spool 4 and which is torsionally deformable because of relative displacement between the one end side and the other end side in the axial direction, a pretensioner 11 which is disposed on the other end side in the axial direction of the spool 4 and which rotates the spool 4 in a direction 10. of winding a seat belt 3 when the vehicle rapidly decelerates, a main pawl 12 which is disposed on one end side in the axial direction of the spool 4, and a sub pawl 13 which is disposed on the other end side in the axial direction of the torsion bar 7. During the normal operation, the main pawl 12 is actuated to lock the spool 4 to prevent the spool 4 from rotating in the direction of withdrawing the seat belt 3. When the vehicle rapidly 15 decelerates, the locking of the spool 4 by the main pawl 12 is released, while the sub pawl 13 is actuated to prevent the other end side in the axial direction of the torsion bar 7 from rotating in the direction of withdrawing the seat belt 3.

摘要： A seat belt retractor including a spool for winding up the seat belt, and a locking mechanism that prevents rotation of the spool. A belt withdrawal sensor actuates when the seat belt is withdrawn at a speed higher than a normal speed. The locking mechanism is actuated based on the actuation of the belt withdrawal sensor. A lock gear rotates with the spool when the locking mechanism is not in operation and rotates relative to the spool when the lock actuation mechanism is in operation. The lock gear actuates the locking mechanism by relative rotation between the lock gear and the spool. The belt withdrawal sensor is disposed on the lock gear allowing the belt withdrawal sensor to oscillate between an inoperative position and an operative position. An oscillation preventive member prevents the oscillation of the belt withdrawal sensor.

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.
