Specific embodiment
In order that the purpose of a kind of split backrest turnover-proof device and split seat of the present invention, technical scheme and excellent
Point becomes more apparent, and below in conjunction with concrete drawings and the specific embodiments, the present invention will be described in further detail.
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combine.
Embodiment one：
Referring to Fig. 3 and Fig. 4, the present embodiment provides a kind of split backrest turnover-proof device, and which includes slide mechanism 100
With lockable mechanism 200.
Fig. 3 is referred to, the slide mechanism 100 includes fixing base plate 110, rotating shaft 120 and slide block 130, wherein described turn
Axle 120 is fixed on the fixed base plate 110, and the slide block 130 is arranged in the rotating shaft 120 and the slide block 130 can
Rotate around the rotating shaft 120.Lockable mechanism 200 includes lock 210, and the structure with slider locking is provided with lock 210.
Lock 210 and slide block 130 in the present embodiment is locked by coupler construction.Draw-in groove can be set on lock 210, in slide block
Snap fit is set on 130；Or draw-in groove can also be set on slide block 130, snap fit is set on lock 210, as long as can realize
Slide block and lock locking.
Slide mechanism 100 and lockable mechanism 200 are separately fixed at into the first backrest 001 in Fig. 1 and during use
The inner side of two backrests 002（Inner side is the side relative with outside, that is, the first backrest and the second backrest connect
Near but unconnected side）.Under normal mounting use condition, the housing chair back turnover-proof device is suffered along vehicle advance side
To inertia force be less than or equal to its preset value, there is no connection, the shape in being separated from each other between slide mechanism and lockable mechanism
State；And gap therebetween can ensure that the independent return motion of both sides split backrest is not interfered, therefore the split
Backrest turnover-proof device has no effect on the upset of current split seat and uses, and can keep the backrest upset of split seat both sides
Action independence each other.When a vehicle is in a collision, the deceleration that the split backrest turnover-proof device bears is big
In setting deceleration（When i.e. the suffered inertia force along vehicle forward direction of the device is more than preset value）, work of the slide block in inertia force
It is connected together with the lower rotary motion for occurring around the shaft and with lock；Simultaneously because the first backrest and the second backrest are deposited
Produce mutually away from motion in the trend of outside reversion, and then band movable slider and lock, make pressure to be produced between slide block and lock
And then lock, being reliably connected for both sides backrest is set up, and then further suppresses the outside motion for inverting of both sides split seat,
The degree for suppressing backrest forward, outwards to overturn, so that the constraint attitude relation between occupant, seat, seat belt is whole
Keep stable in individual collision process, and then reduce the probability that heel row occupant sustains damage in collision accident.Wherein, the Split seat
The preset value of chair back turnover-proof device can be determined according to actual tests.
It should be noted that the lock in the present embodiment can be it is any can be with the device of slider locking.Shown in Fig. 4
Lockable mechanism is only a preferable embodiment.Preferably, slide mechanism 100 also includes the first installed part 101, at fixed bottom
Installing hole is provided with plate 110, whole slide mechanism can be fixed on backrest by the first installed part 101.Locking
Mechanism also includes the second installed part 202, on the main part 210 of lock is provided with installing hole, can be with by the second installed part 202
Lockable mechanism is fixed on backrest.First installed part and the second installed part can be fixing bolt or fixing screws.
Referring to Fig. 3, the slide block 130 in the present embodiment includes sleeve 131 and the holding firmware being fixed on the sleeve 131
132, the sleeve 131 is arranged in the rotating shaft 120, and the rotation of the sleeve 131 further drives the holding firmware 132 to rotate,
Wherein can be locked by coupler construction between holding firmware 132 and lock.Embodiment two：
The present embodiment is the improvement of embodiment one.Narration is not repeated in the present embodiment with one identical content of embodiment.
Referring to Fig. 5, the slide block mechanism in the present embodiment includes fixing base plate 110, rotating shaft 120, slide block 130 and elastic spacing
Part 140, wherein the rotating shaft 120 is fixed on the fixed base plate 110, the slide block 130 be arranged in the rotating shaft 120 and
The slide block 130 can be rotated around the rotating shaft 120, and one end of the spacing elastic component 140 is fixed on the fixed base plate 110
On, and the other end of the spacing elastic component 140 abutted with the slide block 130.Arrange elastic spacing one rear slider 130 to be subject to
The resistance of elastic spacing one 130, therefore slide block 130 must pull against elastic spacing one when will rotate to the position contacted with lock
The rotation position that resistance, so setting enable to slide block is more controllable, so that the setting of preset value is more accurate.
Preset value can be adjusted on demand by the rigidity of spacing elastic component.
Elastic spacing one in the present embodiment can be the torsion spring of leaf spring or similar to Clock and Watch clockwork spring.
Embodiment three：
The present embodiment is the improvement of embodiment two.Narration is not repeated in the present embodiment with two identical content of embodiment.
Referring to Fig. 6, the slide block mechanism in the present embodiment is except fixed base plate 110, rotating shaft 120, slide block 130 and elastic spacing one
Outside 140, positive stop lug boss 150 is additionally provided between the spacing elastic component 140 and described 130, the positive stop lug boss 150 is fixed
On the sleeve of the slide block 130, the spacing elastic component 140 is abutted with the positive stop lug boss 150.As the outer wall of sleeve is
Cylinder, therefore spacing elastic component is less with the contact area of sleeve, it may occur that the situation of slippage, because the present embodiment
Positive stop lug boss is provided with where slide block 130 is contacted with spacing elastic component.Spacing elastic component is increased after positive stop lug boss is set
Active area to slide block so that the slide mechanism of the split backrest turnover-proof device and lockable mechanism locking it is pre-
If value is more accurately controllable.
By the size for adjusting the rigidity and positive stop lug boss of spacing elastic component, preset value can be adjusted on demand.
Example IV：
The present embodiment is the improvement of embodiment three.Narration is not repeated in the present embodiment with three identical content of embodiment.
Referring to Fig. 7 to Fig. 9, the slide block mechanism in the present embodiment is except fixed base plate 110, rotating shaft 120, slide block 130, elasticity limit
Outside position part 140 and positive stop lug boss 150, balancing weight 160 is also provided with the free end of slide block 130.By adjusting balancing weight
The size of quality, the rigidity of spacing elastic component and positive stop lug boss, can adjust preset value on demand.
The cooperation of slide mechanism 100 and lockable mechanism 200 is as shown in Figure 9.
Based on same inventive concept, the present invention also provides a kind of split seat, and which includes split backrest and to take up an official post
Split backrest turnover-proof device described in meaning embodiment.The slide mechanism and locking of the split backrest turnover-proof device
Mechanism is separately mounted to the inner side of two neighboring backrest.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more concrete and detailed, but and
Therefore the restriction to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, some deformations and improvement can also be made, these belong to the guarantor of the present invention
Shield scope.Therefore, the protection domain of patent of the present invention should be defined by claim.
