A seatbelt retractor that includes a locking mechanism to prevent rotation of a spool in an extracting direction, a ratchet gear 7 and a locking gear 30 that integrally rotate with the spool, a clutch 50 that moves a pawl 9 from a rest position to an engaging position with respect to the ratchet gear 7, a clutch biasing member that biases the clutch 50 in a retracting direction and in a extracting direction, and a connecting mechanism to connect the clutch 50 to the locking gear 30. When extraction of the webbing is locked, a direction of biasing to rotate of the clutch 50 is maintained in the extracting direction so that the amount of retraction of the webbing required to release the lock is reduced to achieve quick release of the lock.

An energy absorbing device, a seat belt retractor, and a seat belt device, that can change an energy absorption characteristic continuously, and improve durability. A base plate that is connected to a spool and has a corrugated groove annularly formed, a cover plate that is opposingly connected to the base plate and has a corrugated groove synchronized with the corrugated groove of the base plate, a plurality of driving pins with a first end inserted into the corrugated groove of the base plate and a second end inserted into the corrugated groove of the cover plate, a plurality of mass bodies that are arranged in respective intermediate portions of the driving pins, and intermediate plates that are inserted with the driving pins, arranged on both sides of the mass bodies, and connected to a locking base.

A dual-web retractor includes a frame having first, second and third sidewalls spaced apart from one another with the second sidewall positioned between the first and third sidewalls, a spool rotatably mounted to and between the first, second and third sidewalls, the spool having a first spool section defined between the first and second sidewalls and a second spool section defined between the second and third sidewalls, a first web having one end coupled to the first spool section, and a second web having one end coupled to the second spool section, wherein rotation of the spool causes the first and second webs to be simultaneously paid taken up on or paid out from the first and second respective spool sections.

An intelligent retractor having a noise removal unit includes: a spool around which webbing is wound; a flywheel which is provided at one side of the spool and rotates along with the rotation of the spool; a locking unit which fixes the flywheel when a predetermined condition for preventing an extension of the webbing is satisfied; and a noise removal unit which rotates along with the rotation of the flywheel when the webbing is retracted, and prevents vibration from being generated in the locking unit.
