  • Patent number: 9283928
    Abstract: Disclosed is a load limiter mounted within a cylindrical spool on which a webbing is wound to constrain a load applied to the webbing from exceeding a preset load, the load limiter including: a first torsion bar inserted into a hollow portion formed at a center of the spool and one end of which is coupled to one end of the spool; and a second torsion bar one end of which is connected to an opposite end of the first torsion bar to be inserted into the hollow portion of the spool together with the first torsion bar and an opposite end of which is coupled to a locker installed at an opposite end of the spool, wherein the torsion bar is configured such that a torsion load limit of the first torsion bar is smaller than a torsion load limit of the second torsion bar.

  • Patent number: 9126565
    Abstract: Disclosed is a retractor for a seat belt including a spool around which a webbing is wound, a frame rotatably coupled with the spool, a flywheel gear provided at a central portion thereof with a driving gear, having one-directional gear teeth formed along an outer circumferential surface thereof, and mounted on one end of the spool, a vehicle sensor locked with the one-directional gear teeth if the frame is inclined at a predetermined angle or more, a lever locked with the one-directional gear teeth if the webbing is withdrawn by a predetermined first length, and separated from the one-directional teeth if the webbing is introduced again so that the webbing is withdrawn by the second length, and an integrated plate including a driven gear, a first plate to adjust the lever according to a withdrawn length of the webbing, and a second plate integrated with the first plate.

  • Patent number: 7350814
    Abstract: A tilt-telescopic apparatus for a steering system allows a tilt restraining means and telescopic restraining means to cooperate via one manipulating lever. A tilt restraint, telescopic restraint, tilt restraint release, and telescopic restraint release are conducive to simultaneous tilt and telescopic engagement by a single manipulation for convenience. The parts of the apparatus, including structural parts for transmitting power to the manipulating lever and the like that can be co-used, can be unified, thus resulting in simplified structure and reduction of manufacturing cost.
