A motorized seat belt system includes: a spindle around which webbing is wound; an output gear connected to the spindle through a power transmission shaft; a torsion portion provided on the power transmission shaft or the output gear; a motor which transmits rotational power to the spindle; first and second reduction gears which are connected to an output shaft of the motor and transmit rotational power of the motor to the output gear; a first rotation amount detecting sensor that measures a rotation angle and a rotation direction of the power transmission shaft; a second rotation amount detecting sensor that measures a rotation angle and a rotation direction with respect to a rim portion of the first reduction gear; and a controller which controls output of the motor based on detection signals from the first rotation amount detecting sensor and the second rotation amount detecting sensor.

A webbing take-up device includes clutch weights. The clutch weights are supported at the base and include engaging portions. The clutch weights move to a rotation diameter direction outer side when the base is rotated, and are capable of transmitting rotary force applied to the base to the spool. The webbing take-up device is provided with a stopper that is capable of relative rotating relative to the base and that is provided with engaged holes, each including an allowing portion and a restricting portion. The allowing portions allow movement of the engaging portions to the rotation diameter direction outer side when the base is rotating to one side. The restricting portions restrict movement of the engaging portions to the rotation diameter direction outer side when the base is rotating to the other side. The restricting portions are formed integrally with the allowing portions.

[Object] To provide a seat belt retractor that is capable of generating a more stable load when restricting a load acting on the seat belt and when absorbing energy, and a seat belt apparatus including the same. [Solution] A seat belt retractor 3 includes a frame 11, a seat belt 4, a spool 12 that is rotatably supported by the frame 11 and that retracts the seat belt 4, a lock mechanism 60 that allows rotation of the spool 12 while not in operation and that prevents rotation of the spool 12 in a seat belt withdrawing direction while in operation, and an energy absorption mechanism 20 that restricts a load acting on the seat belt 4 and that absorbs energy of an occupant. In the seat belt retractor 3, the energy absorption mechanism 20 includes a first energy absorption member 21 that absorbs energy through a rotational difference between the spool 12 and the lock mechanism 60, a first energy transmission member 22 that is attached on one end side of the first energy absorption member 21, a second energy transmission member 23 that meshes with the first energy transmission member 22, and a second energy absorption member 24 that absorbs energy through a rotational difference between the second energy transmission member 23 and the spool 12.

In a belt retractor (10) for a seat belt comprising a belt reel (12) onto which webbing (14) can be wound while being spring-loaded and comprising a tensioning device (16) which is adapted to act on the belt reel (12) in a winding direction (A), a control (18) is provided which is adapted to activate the tensioning device (16) when the seat belt is unloaded and not fastened.

A pretensioner and safety belt assembly may include includes a base member fixed to a vehicle, a torsion shaft having a first side and a second side rotatably supported on the base member, a torsion tube having a first end portion fixed on an external surface of the torsion shaft and a second end portion rotatably supported on the external surface of the torsion shaft wherein a belt configured to restrain an occupant is wound around an external surface of the torsion tube, a traction wire wound around an end portion of the torsion shaft on an opposite side to where the torsion tube is fixed to the torsion shaft in an opposite direction to a direction in which the belt is wound, and a pulling device configured to pull the traction wire to rotate the torsion shaft.

A webbing take-up device includes a spool, a lock base that restricts pull-out direction rotation of the spool in a vehicle emergency, and a linear energy absorbing wire that deforms so as to permit pull-out direction rotation of the spool at or above a force limiter load when the lock base has restricted pull-out direction rotation of the spool. The webbing take-up device further includes a housing with which the energy absorbing wire engages along a radial direction inside face of the housing, and a winder section provided at a radial direction inside of the housing. The winder section is capable of rotating together as a unit with the spool, and takes up the energy absorbing wire by being rotated. Moreover, a wire guide and a lever are provided between the winder section and the housing. The wire guide and the lever pinch and deform the energy absorbing wire.

A webbing take-up device includes a spool, a lock gear that restricts pull-out direction rotation of the spool, a force limiter mechanism that permits pull-out direction rotation of the spool at or above a force limiter load, and a pawl that switches the force limiter load. The webbing take-up device further includes a cylinder section that includes a first cylindrical portion and a second cylindrical portion, a gas generator that supplies gas into the second cylindrical portion, and a piston section that is moved along the first cylindrical portion by an increase in pressure inside the second cylindrical portion and the first cylindrical portion so as to press and displace the pawl.
