摘要： The disclosed seat belt retractor may include a spool for retracting a seat belt, a torsion bar, a pre-tensioner, and a locking device. 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： To further reduce variation in the maximum limited load by a seat belt load limiting mechanism composed of a torsion bar and a shearing member. When a spool rotates in the belt withdrawing direction relative to the locking base, energy absorbing (EA) mechanism action only by shear deformation of shear pins is first conducted so that the entire EA load is only the EA load by the shear pins. After the EA load by the shear pins becomes the maximum EA load, the seat belt is withdrawn by a predetermined amount and the EA action by torsional deformation of a torsion bar is conducted in addition to the EA action by the shear pins. Since the EA action only by the shear pins is first conducted, it is possible to reduce variation in the maximum limited load during the shear deformation of the shear pins.

摘要： A seatbelt retractor capable of variably setting the limited load applied to the seatbelt depending on the emergency state includes a support shaft portion of a spool, which is provided with a second EA mechanism coaxial with the spool. An energy absorbing pin of a third EA mechanism is inserted to be fit in the axial hole of the spool. In the emergency state, the torsion bar is twisted and the energy absorbing pin is pulled out of the spool to absorb energy. At the same time, in the state where the rotation of the second energy absorber support member is locked by the lever, the first energy absorber support member rotates to deform the energy absorbing plate so as to absorb energy. As the second energy absorber support member rotates when the locked rotation is released, the energy absorbing plate is not deformed, and the energy absorption is finished.

摘要： A seat belt retractor including a tension reducer which is compact in the axial and radial directions. The retractor includes a reducer spring that always biases a bush shaft, which rotates together with a spool, to rotate in the belt winding direction, and a main spring can selectively bias the spool in the belt winding direction. A lever of the bush shaft and a Geneva wheel form an assembly for memorizing the rotational amount of the spool in the belt winding direction relative to the ratchet gear when the main spring does not bias the spool in the belt winding direction. The assembly is arranged in the ratchet gear so that the retractor with the tension reducer is formed to be compact in the axial direction and the radial direction.
