Description

Four-way electric waist support

Technical field

This utility model relates to Seatback device technical field, refers in particular to a kind of four-way electric waist support.

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.

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 four-way electric waist support for the deficiencies in the prior art, and this four-way is electronic Waist torr solves existing for existing Seatback device: the defects such as yielding, comfortableness is poor.

For achieving the above object, this utility model is achieved through the following technical solutions:

Four-way electric waist support, including quadra, very back is slidedly arranged on quadra, and the very lower hinge of back has Fagging, the bottom of gripper shoe is slidedly arranged on quadra, and gripper shoe is equipped with the first controller, very back and is equipped with the second control Device.

Quadra includes steel wire, overall U-shaped, the two ends on steel wire top molding hook portion, the top two of steel wire respectively Limit is connected by the sheet of horizontally set, both sides, middle part are connected by the top back of horizontally set, bottom is sliding sets gripper shoe.

First controller drives the first drag-line, and gripper shoe is equipped with pulley, and the first drag-line passes also from the upper end of very back The upper end of very back again it is fixed on after walking around pulley.

Second controller drives the second drag-line, the second drag-line to be fixed on top back after sheet passes.

Very back is plate-shaped, very in bending below the hinged place of back and gripper shoe.

Very back forms hook.

Very back also forms reinforcement, and this reinforcement contacts with top back.

First controller, second controller are installed on the back of top.

The beneficial effects of the utility model are: very back is hinged with gripper shoe and outside jack-up or draw in opposite directions, is encircleing Internal stress free during Qiing, reduces in-fighting, repeatedly run will not fatigue deformation, add very waist supporting area simultaneously, except Having well support to waist, caudal vertebra position also functions to supporting role, comfortableness strengthens.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is structure schematic diagram 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 Fig. 2, this utility model four-way electric waist support include: steel wire 1, very back 2, gripper shoe 3, first are controlled Device the 4, first drag-line 5 processed, pulley 6, second controller the 7, second drag-line 8, sheet 9, top back 10, hook 11.

This utility model includes quadra, and very back 2 is slidedly arranged on quadra, and the very lower hinge of back 2 has Fagging 3, the bottom of gripper shoe 3 is slidedly arranged on quadra, and very back 2 is equipped with second controller 7, and gripper shoe 3 is equipped with One controller 4, is outwards straightened by control very back 2 and reaches very waist effect, use the mode of hinged support plate 3 to reduce Loss.

This utility model includes steel wire 1, overall U-shaped, the two ends on steel wire 1 top molding hook portion respectively, is used for hanging This utility model device, the both sides, top of steel wire 1 are connected by the sheet 9 of horizontally set, and horizontally set is passed through on both sides, middle part Top back 10 connect, the sliding gripper shoe 3 that sets in bottom, steel wire 1, sheet 9, top back 10 form quadra structure, very back 2 Upper end be slidedly arranged on steel wire 1, very back 2 can move along steel wire 1, and gripper shoe 3 also can move along steel wire 1.

Very back 2 of the present utility model, gripper shoe 3, sheet 9, top back 10 are all plastic materials, can alleviate entirety Weight, and increase the support to human body, increase non-deformability simultaneously.

Very back 2 of the present utility model is plate-shaped, very in bending below back 2 and the hinged place of gripper shoe 3, when very waist When plate 2 is outwards endured out, the very part of back 2 bending, it is possible to well adapt to the waist of user, allow the waist of user obtain The support more fitted, strengthens comfortableness of the present utility model.

The upper end of very back 2 of the present utility model has bending section, enables drag-line to stablize through and to fix.

The bottom of gripper shoe 3 of the present utility model has bending section, and more convenient gripper shoe 3 rotates.

Very back 2 of the present utility model forms hook 11, if fixed position to be increased, it is possible to use this hook 11.

Very back 2 of the present utility model also forms reinforcement, and this reinforcement can contact with top back 10 so that top waist Very back 2 fast reaction can be made when plate 10 outwards straightens, outwards endure out.

This utility model have employed two kinds of control structures.

The first is that gripper shoe 3 is equipped with the first controller 4.First controller 4 drives the first drag-line 5, and gripper shoe 3 is joined Be provided with pulley 6, the first drag-line 5 from the upper end of very back 2 across and around being again fixed on the upper end of very back 2 after pulley 6, when When first controller 4 drives the first drag-line 5, pulley 6 can be pulled, so that gripper shoe 3 is slided along steel wire 1, in hinged relationship Under effect, very back 2 is outwards ejected, it is achieved the support to human body waist.

The second is, very back 2 is equipped with second controller 7.Second controller 7 drives the second drag-line 8, the second drag-line 8 After sheet 9 passes, it is fixed on top back 10, when second controller 7 drives the second drag-line 8, top back 10 can be made outwards to push up Going out, thus outwards ejected by very back 2, very back 2 upper end edge steel wire 1 slides.

First controller 4 of the present utility model, second controller 7 can be installed on the two ends of top back 10.

The hook portion at the two ends, top of steel wire 1 of the present utility model is used for fixing this device, and the bottom of steel wire 1 is also used for fixing This device, when pushing up back 10 deformation by very back 2 jack-up, very back 2 slides along steel wire 1, when gripper shoe 3 is pulled along steel wire During 1 slip, due to hinged relationship, very back 2 is outwards ejected, very waist regulating effect can be realized.

This utility model have employed the mode that very back is hinged with gripper shoe, internal stress free during arching upward, and reduces In-fighting, repeatedly run will not fatigue deformation, add very waist supporting area, except waist there being well support, to tail simultaneously Vertebra position also functions to supporting role, and 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.
