Abstract
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.
Claims12
An intelligent retractor comprising:
- 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,
- wherein first gear teeth are formed at a circumference of the flywheel, the locking unit includes a housing, and a locking lever rotatably provided in the housing, and fixes the flywheel as the locking lever is caught by the first gear teeth when the predetermined condition for preventing an extension of the webbing is satisfied, and the noise removal unit rotates along with the rotation of the flywheel when the webbing is retracted, and presses the locking lever so as to prevent vibration from being generated in the locking unit, and
- wherein second gear teeth are formed at a circumference of the flywheel, and the noise removal unit includes a rotating gear which meshes with the second gear teeth, and a pressing member which presses the locking lever by the rotation of the rotating gear.
