Description
Technical field
This utility model relates to Seatback device technical field, refers in particular to a kind of seat backrest waist straightening up device.
Background technology
Existing Seatback device, can produce internal stress during arching upward, and in-fighting is relatively big, the most repeatedly runs,
The probability of deformation is the highest, and is usually in middle and lower part the very waist to outward turning, is also substantially that this position supports and uses all
Waist, comfortableness is poor.Meanwhile, existing back-rest means for chair uses the metalworks such as steel wire mostly, and whole mechanism is heavier, number of parts
Many, Assembling Production step is complicated, assembles production efficiency low.
Therefore, defect based on above-mentioned existing Seatback device, need existing Seatback device is changed
Enter.
Summary of the invention
The purpose of this utility model is to provide a kind of seat backrest waist straightening up device, this seat for the deficiencies in the prior art
Backrest very waist device solves existing for existing Seatback device: yielding, comfortableness is poor, heavier, assemble complicated etc.
Defect.
For achieving the above object, this utility model is achieved through the following technical solutions:
Seat backrest waist straightening up device, including upper bracket, lower carriage, connects between upper bracket, lower carriage and has plastic cement to connect sheet,
The two ends of upper bracket have hook portion, and plastic cement connection sheet has the stopper slot for stay guy.
On plastic cement connection sheet, there is chute.
It is to connect upper bracket, the multiple parallel sheet of lower carriage that plastic cement connects sheet.
It is multiple horizontal, longitudinal combination connection upper bracket, sheets of lower carriage that plastic cement connects sheet.
One wave part is molded on plastic cement connection sheet.
The beneficial effects of the utility model are: have stopper slot on employing plastic cement connection sheet and fix the structure of drag-line,
Decreasing the application of the metalworks such as steel wire, alleviate the weight of whole mechanism, comfortableness is more preferable, and simplifies drag-line and drive machine
The structure of structure, number of parts is less, and structure is simpler, and Assembling Production step is more succinct, and production efficiency is higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
See that Fig. 1, this utility model seat backrest waist straightening up device include: upper bracket 1, lower carriage 2, plastic cement connect sheet 3, spacing
Groove 4, drag-line 5, controller 6, chute 7, clip 8, fixation hook 9.
This utility model includes upper bracket 1, lower carriage 2, connects and has plastic cement to connect sheet 3, mould between upper bracket 1, lower carriage 2
On glue connection sheet 3, there is the stopper slot 4 for stay guy 5.
Having clip 8 on the telescopic drag-line 5 that the controller 6 that this utility model coordinates drives, this is telescopic draws
One end of rope 5 connects hook, and clip 8 connects the stay guy having length fixing, and one end of this stay guy connects to be had admittedly
Determine hook 9.
Plastic cement of the present utility model connects the chute 7 on sheet 3 with clip 8 activity for drag-line 5.
All having stopper slot 4 on the plastic cement connection sheet 3 of arranged on left and right sides of the present utility model, a stopper slot 4 is used for fixing
Telescopic drag-line 5, the stay guy that fixation hook 9 connects is stuck in another stopper slot 4.
It can be to connect upper bracket 1, the multiple parallel sheet of lower carriage 2 that plastic cement of the present utility model connects sheet 3, it is possible to
To be multiple horizontal, longitudinal combination connection upper bracket 1, sheets of lower carriage 2, it is latter configuration shown in figure, whether
Any, can realize function described in the utility model, only part-structure slightly needs to make an amendment, and such as chute 7 is slightly
Difference, therefore not to repeat here.
This utility model can coordinate type hand controller or power type controller, it is illustrated that for power type controller.
This utility model is very simple with the assembling of controller, only drag-line 5, stay guy need to be respectively clamped into plastic cement and be connected
In the stopper slot 4 of sheet 3, and clip 8 is snapped in chute 7, i.e. complete to assemble.
Upper bracket 1 two ends of the present utility model have hook portion, are used for being fixed on seat, and plastic cement connects the middle part of sheet 3 can
To install support additional, increasing the laminating with user back, plastic cement connects can also mold one wave part on sheet 3, increase resistance to deformation
Power；Drag-line 5 is used entirety outwards to be ejected, so, the two ends of lower carriage 2 need not hook portion.
This utility model uses as follows, and controller 6 drives drag-line 5 to tighten up, then the extension being connected with drag-line 5 due to fixation hook 9
Hook position is fixed, so clip 8 slides in chute 7, makes this utility model entirety the most externally endure, thus realizes very waist effect
Really, when controller 6 loosens drag-line 5, then overall interior shifting resets.
This utility model decreases the application of the metalworks such as steel wire, alleviates the weight of whole mechanism, simplifies drag-line and drives
The structure of motivation structure, number of parts is less, and structure is simpler, and Assembling Production step is more succinct, and production efficiency is higher.
Have employed the mode that very back is hinged with gripper shoe, internal stress free during arching upward, reduce in-fighting, repeatedly transport
Row will not fatigue deformation, adding very waist supporting area simultaneously, except waist there being well support, caudal vertebra position being also functioned to
Supporting role, comfortableness strengthens.
Certainly, the embodiment of the above, preferred embodiments the most of the present utility model, and unrestricted this utility model
Practical range, therefore all equivalences done according to structure, feature and the principle described in this utility model claim change or repair
Decorations, all should be included in this utility model claim.
