What Fig. 3 a were provided is the structural representation of recliner body 1 in the prior art, and Fig. 3 b are illustrated that in the present invention and adjusted
The structural representation of angle device body 1.As shown in Figure 3 a and Figure 3 b shows, the crumple hole in the recliner that present embodiment is provided
Component is included with rotation hole 2, and to be starting point produce direction to extend to open type formed by the edge of recliner body 1 logical along described
Pore structure, in this, as the rotation hole of the recliner body 1 in the present embodiment.The processing technology of open type through-hole structure can be adopted
Realized with existing process.When chair framework in the present embodiment is by external force collision, chair framework body can
By rotation hole 2, rotating bolt 6 and the relative motion of rotation hole 2 and produce frictional force, the torque and GB13057 of the frictional force
Quite, now rotating bolt 6 is in the side of producing along recliner body 1 for the torque of impact in chair framework crumple experiment
During sliding, while can also be rotated along through-hole structure, so as to sponge the energy of test force effect, drop
It is low to be transferred to the shock strength of seat, and the purpose for saving personal security in vehicle from damage can be reached.
As shown in figures 4 a and 4b, the recliner that present embodiment is provided also includes reinforcing plate 4, and reinforcing plate 4 can be proper
The lateral surface of recliner body 1 is arranged on well, and is unlikely to have influence on the rotation of recliner body 1.The crumple aperture member is also
Including rotation slot 5, rotation slot 5 is arranged on position corresponding with rotation hole 2 in reinforcing plate 4, and length direction is produced with described
Direction is parallel, thus rotation slot 5 be located at chair framework normal rotation when rotary motion trace on.The length of rotation slot 5, which is more than, to be turned
The length in dynamic hole 2.Certainly, it is further opened with and the rotating hole on recliner body 1 in addition to rotation slot 5 is set in reinforcing plate 4
The corresponding rotating hole in 3 position.So in use, the main function of reinforcing plate 4 is to make up adjuster possibly not reaching in itself
To the requirement of rotation hole Opening length, thus increase reinforcing plate to ensure that the specification requirement of rotation hole can be met.
Because in crumple process of the test, recliner can deform, rotary motion trace can depart from track during normal rotation, need
Reserve enough amount of tolerance to make up trail change caused by deformation, it is ensured that rotate smooth, therefore the rotation slot 5 in the present embodiment
Width need to be slightly larger than penetrating the diameter of rotating bolt 6 therein, the about 1.5 times diameters of bolt.
Furthermore, it is contemplated that the length of the displacement of chair framework and rotation slot 5 is proportional in process of the test, rotation slot
5 length is longer, then the displacement of chair framework is bigger.In view of GB13057 laws and regulations requirements：Tested on the top of chair framework
Power F1 is acted on, and the displacement of the top stress of chair framework forward is not less than 100mm and no more than 400mm；Under chair framework
Portion is acted on by test force F2, and the displacement of center of effort's point of chair framework forward is not less than 50mm.Therefore, the length of rotation slot 5

In required displacement, and meet：
T≤(F1*L1+F2*L2)*(sinα+cosα*μ2)*d/(2μ1*L3)；
In formula：T is the tightening torque of rotating bolt 6, the first test force that F1 is subject to for the top of the chair framework, L1
The second test force being subject to for F1 to the pivot O arm of force, F2 for the bottom of the chair framework, L2 is F2 to pivot
The O arm of force, F3 is the frictional force applied when the rotating bolt 6 rotates to the chair framework, and L3 is F3 to pivot O's
The arm of force.Pivot O is the center of rotating hole 3.
The specific derivation of above-mentioned conclusion is as follows：
F1*L1+F2*L2≥F3*L3
Wherein, in F3=μ 1*F, formula：F is normal pressure of the rotating bolt 6 to reinforcing plate 4, and μ 1 is rotating bolt 6 with strengthening
The coefficient of friction that plate 4 is contacted.
To sum up obtain formula 1.：F≤(F1*L1+F2*L2)/(μ1*L3)
As shown in fig. 6, the formula of the tightening torque of rotating bolt 6 is：T=(F4sin α+F4cos α * μ 2) * d/2
In formula, T is the tightening torque of rotating bolt 6, and α is the angle of thread of rotating bolt 6, and F4 is the spiral shell of rotating bolt 6
The pressure that line is born, μ 2 is the screw thread of rotating bolt 6 and the coefficient of friction of nut contact surface, and d is in the screw thread of rotating bolt 6
Footpath.The pitch diameter of thread, the diameter that bus passes through the equal imaginary cylinder of the raised width both with groove of tooth form.
Because rotating bolt 6 is identical with the pressure that the screw thread of rotating bolt 6 is born to the normal pressure of reinforcing plate 4, therefore F4=
F。
Therefore, formula is 2.：F=2T/ [(sin α+cos α * μ 2) * d]
Composite type 1. and formula 2., the tightening torque T of rotating bolt 6, the central diameter d of the screw thread of rotating bolt 6, rotating bolt 6
Angle of thread α derivation it is as follows：
2T/[(sinα+cosα*μ2)*d]≤(F1*L1+F2*L2)/(μ1*L3)
Therefore：
T≤(F1*L1+F2*L2)*(sinα+cosα*μ2)*d/(2μ1*L3)
Therefore, when selecting bolt, friction coefficient μ 1, the screw thread of rotating bolt 6 that rotating bolt 6 is contacted with reinforcing plate 4
The central diameter d of friction coefficient μ 2, the screw thread of rotating bolt 6 with nut contact surface and the angle of thread α of rotating bolt 6 substitute into above formula
In, the satisfactory bolt that can select can then set the length and width of rotation slot 5 in reinforcing plate 4 as rotating bolt 6
Degree.If undesirable, screw thread specification is set to be substituted for M (n+2) for Mn, n is more than and equal to 6, until the lashing force of rotating bolt 6
Square is met：T≤ (F1*L1+F2*L2)*(sinα+cosα*μ2)*d/(2μ1*L3).Bolt tightening torque is with reference to existing screw thread
