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.

The torsion bar may disposed inside the spool, wherein one side of the torsion bar is connected to the spool, and configured to absorb energy of movement of an occupant while being deformed under torsion. The pre-tensioner may be positioned at one side of the spool and configured to generate a rotating drive force for rotating the spool in a retracting direction in a condition of rapid deceleration of a motor vehicle. The locking device may be capable of locking another side of the spool such that a rotation of the spool in a withdrawal direction is suppressed at both an operating time of the pre-tensioner and a non-operating time of the pre-tensioner.

摘要： A seat belt retractor includes a seat belt, a spool, and an emergency locking mechanism for preventing the spool from rotating in a belt withdrawal direction. The emergency locking mechanism allows rotation of the spool not in operation and prevents the rotation of the spool in the belt withdrawal direction when in operation. A lock gear includes ratchet teeth on an outer periphery of the emergency locking mechanism arranged in an annular shape. The lock gear rotates with the spool when the emergency locking mechanism is not in operation and actuates the locking mechanism when the emergency locking mechanism is in operation. A vehicle sensor includes an engaging claw and detects a vehicle deceleration larger than a predetermined deceleration. The engaging claw engages with one of the ratchet teeth to prevent rotation of the lock gear in the belt withdrawal direction.
