Abstract
The utility model provides a leather chair backrest adjusting mechanism, which is characterized in that the adjusting mechanism is integrally disposed inside a leather chair backrest. The adjusting mechanism comprises an upper sprocket, a lower sprocket, two chains, a cylindrical roll and a rotary handle, wherein the two chains are sleeved in parallel onto the two sprockets, the cylindrical roll is horizontally disposed and fixedly connected between the two chains, and the rotary handle protruding the leather chair backrest is disposed on one end face of any one sprocket. When in use, position of the cylindrical roll can be adjusted by rotating the rotary handle to drive the sprockets and the chains thereon to rotate, thereby concave-convex position of the leather chair backrest can be adjusted to be adaptable to users of different heights, and simultaneously, the adjusting mechanism has the advantages of simple mechanism, convenient production, and capability of greatly enhancing applicable popularization to the chair and comfortableness thereof.
Description
Technical field
The utility model relates to a kind of skin chair back governor motion of regulating position, the concavo-convex place of skin chair back.
Background technology
Existing office skin chair, its back part structure generally has two kinds, and a kind of is that the backrest inner surface configuration is that the plane is provided with.Another kind is that the backrest interior shape is set to roughness, be because people's back vertebra normally has flexibility like this, if being the plane, backrest is provided with, after that occupant has leaned on of a specified duration, its back is just tired easily, and back is set to concavo-convex with people back coupling, so just meets ergonomics, and the occupant leans against and will feel more comfortable on the backrest.But existing this skin chair, its back rest shape is and fixedly installs, and it has can only adapt to the fixedly user's of height defective, and the user of different heights uses, and will feel very uncomfortable.
So how a kind of skin chair back that adapts to the user of different heights is provided, promptly becoming the present technique field has a difficult problem to be solved.
The utility model content
Technical problem to be solved in the utility model promptly is to provide a kind of position, the concavo-convex place of skin chair back of adjusting in order to overcome above-mentioned the deficiencies in the prior art, makes its user's that can adapt to different heights skin chair back.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of skin chair back governor motion, its characteristics are, described skin chair back governor motion is wholy set in skin chair back inside, comprise two sprocket wheels up and down, be socketed in two chains on two sprocket wheels side by side, be fixed with horizontally disposed cylindrical roller bar between two chains, an end end face of arbitrary sprocket wheel is provided with the rotating handles that stretches out the skin chair back therein.
When the utility model uses, can drive sprocket wheel and the rotation of the chain on it by rotating rotating handles, and then regulate the position of cylindrical roller bar, so both can adjust position, the concavo-convex place of skin chair back, make it adapt to the user of different heights.
As further optimization, be provided with two roller bar tracks along chain near a side direction of showing in the skin chair back, the two ends of cylindrical roller bar are connected on the roller bar track slidably, but slide in orbit in restrict rollers bar two ends like this, and it is convenient to make adjustment get up.
In sum, the utility model overcomes the deficiency in the existing skin chair back design, not only can allow the crowd that keeps sitting posture for a long time (as long-time in the face of computer work or office staff etc.) can be at any time according to own needs change chair back shape, keep the comfort of seat from the angle of ergonomics, keep long-term sitting work crowd's vertebra health; Also can allow simultaneously the different different crowd of build backrest very comfily; It is simple that while the utility model also possesses mechanism, is convenient to produce, and strengthens the suitable crowd of chair and the advantage of comfort level greatly.
Description of drawings
Fig. 1 is the side view that skin chair of the present utility model is installed.
It among Fig. 2 the structural representation when the cylindrical roller bar is in diverse location among Fig. 1.
Fig. 3 is the chair back front view that skin chair of the present utility model is installed.
For clearly showing the utility model, so the skin chair part-structure in above-mentioned accompanying drawing has adopted the shade that does not influence the demonstration of the utility model structure to represent.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further:
During concrete enforcement, as shown in figures 1 and 3, a kind of skin chair back governor motion, described skin chair back governor motion is wholy set in skin chair back inside, comprise two sprocket wheels 2,1 up and down, be socketed in side by side between 4, two chains 4 of two chains on two sprocket wheels 2,1 and be fixed with horizontally disposed cylindrical roller bar 3, an end end face of lower end sprocket wheel 1 is provided with the rotating handles 6 that stretches out the skin chair back therein.Be provided with two roller bar tracks 5 along chain 4 near a side direction of showing in the skin chair back, the two ends of cylindrical roller bar 3 are connected on the roller bar track 5 slidably.When it uses, can drive sprocket wheel 2,1 and 4 rotations of the chain on it by rotating rotating handles 6, and then regulate the position of cylindrical roller bar 3, so both can adjust position, the concavo-convex place of skin chair back, as shown in Figure 2, make it adapt to the user of different heights.
