Abstract
The utility model relates to an automotive seat fitting, and particularly to a torsion spring type manual lumbar support adjustor of an automotive seat. The adjustor comprises an upper housing, a lower housing, a pull wire, a reel and a shift fork. The torsion spring type manual lumbar support adjustor further comprises a torsion spring which is equipped between the reel and the shift fork. A semi-cylindrical clamping terminal is equipped below an annular boss of the shift fork. The reel is provided with a semi-cylindrical brake terminal. The torsion spring is sleeved on the clamping terminal through a hook whereon. In assembling, the brake terminal on the reel is equipped at an opposite surface of the clamping terminal in the torsion spring. An outer diameter of the torsion spring is larger than the inner diameter of the boss on the upper housing. As the structure is adopted, the torsion spring type manual lumbar support adjustor of the automotive seat has the following advantages: saved labor in operation, convenient and flexible adjustment, simple and reasonable structure, low cost, easy production control, high qualified rate of the product, etc.
Description
Technical field
The utility model relates to a kind of automobile seat accessories, a kind of specifically torsion spring type automobile chair manual waist holder regulating control.
Background technology
The Domestic Automotive Industry growth momentum was powerful in recent years, China become continue U.S.A, day after the 3rd automobile produce the country of breaking ten million per year, get into ten million automobile superpower ranks.
Along with the raising of individual family income, automobile has been not only the office and the walking-replacing tool of office and business unit, and automobile has become the first-selection of present household consumption; People propose the higher requirement except brand, safety and quality for automobile; The traveling comfort of pay attention to driving more, this wherein the traveling comfort of automotive seat be vital, we know; In order to reduce the fatigue that long-duration driving brings; The waist holder is installed on the automotive seat usually, and waist holder in the market has been widely used in the automotive seat control system, manually waist holder regulating control
BeCritical component in the waist holder.
Although the manual waist holder regulating control that uses has in the market been realized the regulating action for the waist holder; But have certain shortcoming and defect, be in particular in: 1., when operation moment of torsion big, the power that need apply during operation is big; Often cause the user to feel inconvenience, effort.2., complex structure, cost is high.3., the craft precision of product requires highly, wayward during production, the qualification rate of product is low.
Summary of the invention
The purpose of the utility model is that a kind of simple and reasonable, adjusting is flexible, cost is low torsion spring type automobile chair manual waist holder regulating control will be provided.
The purpose of the utility model is achieved in that this regulating control comprises upper shell, lower house, backguy, line wheel, shift fork; It also comprise one be provided with online take turns and shift fork between torsion spring; Be provided with a semi-cylindrical clamping terminal below the described shift fork annular boss; Have a semi-cylindrical braking terminal on the line wheel, torsion spring is contained on the clamping terminal through the rhampotheca that returns on it, and the braking terminal during assembling on the line wheel is arranged on the opposite of clamping terminal in the torsion spring.
The external diameter of described torsion spring is greater than the internal diameter of upper shell convex platform.
The utility model since adopt said structure have rapid operation, easy to adjust flexible, simple and reasonable, cost is low, produce control and product quality advantages of higher easily.

Fig. 3 is the utility model shift fork and another angle perspective view of torsion spring assembling.
The specific embodiment
By accompanying drawing 1,2, shown in 3: this regulating control comprises upper shell 1, lower house 2, backguy 3, line wheel 4, shift fork 5; It also comprise one be provided with online take turns 4 and shift fork 5 between torsion spring 6; Be provided with a semi-cylindrical clamping terminal 7 below described shift fork 5 annular boss; Have a semi-cylindrical braking terminal 8 on the line wheel 4; Torsion spring 6 is sleeved on the clamping terminal 7 through the hook 10 that returns on it, and the braking terminal 8 during assembling on the line wheel 4 is arranged on the opposite of clamping terminal 7 in the torsion spring 6, and the external diameter of torsion spring 6 is greater than the internal diameter of upper shell 1 convex platform 9.
Principle of work:
During use; Regulating control linked to each other with the waist holder be installed in a side of automotive seat; The user is through operating handle twisting shift fork 5, and it is to drive torsion spring 6 to rotate with line wheel 4 that shift fork 5 rotates, and line wheel 4 drives backguy 3 props the waist holder; At this moment torsion spring 6 reduced diameter and upper shell 1 boss 9 inwalls produce the gap, and it is 4 free to rotate that shift fork 5 and line are taken turns.
When the waist holder reached the requirement position, the antagonistic force that the waist holder receives was transmitted to line wheel 4 through backguy, and the hook 10 that returns that the braking terminal 8 of line wheel 4 drags torsion spring 6 increases torsion spring 6 external diameters, and the inwall tensioner of torsion spring 6 and upper shell plays the locked effect of braking.
When the waist holder need be set level, its working process was identical with above-mentioned principle.
