Abstract
An intelligent retractor having a mode switching lever 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 mode switching lever which rotates in a state in which the webbing is extended by a predetermined length or greater, and operates the locking unit so that the locking unit fixes the flywheel.
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;
- a mode switching lever which rotates in a state in which the webbing is extended by a predetermined length or greater, and operates the locking unit so that the locking unit fixes the flywheel;
- and
- an auxiliary rotating unit which rotates the mode switching lever in a state in which the webbing is extended by the predetermined length or greater,
- wherein the mode switching lever includes a switching protrusion, and the auxiliary rotating unit includes a rotating member which shares the same rotation axis with the flywheel and rotates along with the rotation of the flywheel, and a disc member which rotates the mode switching lever by pushing the switching protrusion in accordance with a rotation angle of the auxiliary rotating member.
