Spring item 56 could occur inside deformation and generate inside tension, and tie when that is, carrier spring 56 and disk external tooth 41 assemble
The circular motion for closing disk external tooth 41, to generate frictional force.The frictional force producing method can generate continual and steady friction
Power.
The embodiment it should be understood that
The noise reduction part 5 is fixed in end card slot 59 by carrier spring 56, easy for installation (to be caught in end card slot 59
It is interior), consistency is high, stability is good (not being affected by temperature), circular arc portion when having evaded noise reduction part 5 around different directions rotation
The variation of diameter.
Preferably as one of the present embodiment, the producing method of frictional force further includes utilizing the end on disk external tooth 41
The frictional force that card slot 59 generates the axial elastic force that noise reduction part 5 applies drives noise reduction part 5 to rotate.
The coiler that noise reduction is carried out at a kind of pair of 3 position of vehicle sense component of the invention, can limit the steel ball of vehicle sense component 3
32 states make occupant after not wearing or wearing safety belt, and steel ball 32 is in defined position, cannot be due to the operation of vehicle
It moves, eliminates the sound that vehicle sense component 3 issues；Equipped with noise reduction part 5, the rotation of disk external tooth 41 of vehicle sense component 3 drives drop
Part 5 of making an uproar rotates synchronously, and when ribbon 7 pulls out, noise reduction part is separated with vehicle sense component 3, and the latch functions of vehicle sense component 3 are restored；Wait knit
When band 7 recycles, noise reduction part pushes down vehicle sense arm 31, limits the movement of steel ball 32；The structure of noise reduction part 5 is simple, and noise reduction part 5 one
Component can be achieved with decrease of noise functions, few (1) compared with other vehicle sense dampening mechanism added parts, (singlehanded can complete) easy for installation,
Performance is stablized, while taking full advantage of the axial space of disk external tooth 41 Yu end cap 8；Weight between noise reduction part 5 and disk external tooth 41
Power or/and elastic force and generate frictional force drive noise reduction part 5 rotate；Or noise reduction part 5 and disk external tooth 41 have when assembling inwardly/
Outside/up/down pressuring direction and the frictional force that generates drives noise reduction part 5 to rotate.Readily available continual and steady frictional force.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
Member, under the premise of not departing from the method for the present invention, can also make several improvement and supplement, these are improved and supplement also should be regarded as
Protection scope of the present invention.
