Abstract

The utility model provides a chair-back structure, a chair-back of which mainly comprises a chair-back board and a back cushion board, wherein, the chair-back board is previously provided with a frame slot provided with a slot, while the back cushion board is the design that a flexible cushion wraps an outer frame provided with a corresponding protruding pin so that the flexible cushion can be fixed in the slot of the frame via the outer frame, and the chair-back board can be firmly combined with the flexible cushion.

Description

The composition structure of the chair back

Technical field

The utility model is a kind of composition structure of the chair back, its chair back mainly is made up of chair back plate and backing plate, wherein chair back plate is preset with the frame groove of a laying draw-in groove, backing plate then is to coat with cushion to have the design that correspondence protrudes out the housing of bayonet lock, the short cushion that makes can be combined in the frame groove by firm compacting by housing, reaches chair back plate can be supported human body back by cushion with buffering purpose.

Background technology

In known back structure with elastic buffer function designs, mainly all be to constitute with plank cooperation foam or by the sheathed wire side of seat back frame, its purpose all is for making the chair back can have the effect of elastic buffer via the setting of elastic material, with promote the user lie by the time comfortableness.

Yet in known technology in order to reach this comfortable purpose, can find that its technological means all is elastic material (as foam or wire side) must be overlapped to be additional on the support body (plank or seat back frame), so under material overlaps the fact of forming in a large number, tend to cause the waste on the cost, though its industry also once actively solved this defective, but be limited to the restriction of technological means, fail to make moderate progress always.

The utility model is point in view of the above problems, the chair back of dark feel seat should have the technology thinking of innovation on the composition of structure, could be under minimum material waste condition and reach the back structure that has elastic buffer function equally, be the most a mental and physical efforts of the precious resources of the earth, therefore then be engaged in the experience of the Specialty Design of chair tool, manufacturing for many years with it, actively research and development improvement is under the discretion of each side's condition is considered, finally design the composition of this structure, can solve the problem of known technology fully.

The utility model content

The purpose of this utility model is to provide a kind of composition structure of the chair back, to reach chair back plate firmly in conjunction with the purpose of cushion.

For achieving the above object, the composition structure of the chair back that the utility model provides, its chair back mainly is made up of chair back plate and backing plate, wherein:

Chair back plate is preset with a frame groove of laying draw-in groove;

Backing plate covers and coats housing by cushion and forms, and the rear end of this housing protrudes out the plural bayonet lock of corresponding draw-in groove;

By above-mentioned member, make backing plate fix with the draw-in groove holding of the corresponding frame groove of its bayonet lock, make the edge of cushion be sandwiched between between housing and the frame groove, reach composition state soft, the mutual cramping of hard.

The composition structure of the described chair back, wherein cushion directly carries out ejection formation and coats combination at housing.

The composition structure of the described chair back, wherein the frame groove of chair back plate below is installed with the adjustment bustle of built-in slide rail, and bustle is adjusted in order can cooperate different users's build and its height of lift adjustment.

The utility model can reach following usefulness:

Because the chair back of the present utility model cooperates the backing plate with elastic buffer function to be formed by the chair back plate that hollow out is provided with the frame groove,, can solve the problem of waste material in the known technology so the additional area of the overlapping between chair back plate and backing plate is very little.And in the design of structural strength, because the hard housing of backing plate outside is to be coated with soft cushion, be fixed in the frame groove for the cushion butt joint by housing again, therefore utilize housing that the edge of cushion is inserted and put fixing purpose with can reaching after the frame groove of chair back plate combines when backing plate, structure is to composition state soft, the mutual cramping of hard, so can promote the steadiness of composition, unexpected disengaging of cushion or easy impaired problem can not take place.

The specific embodiment

Be the function and benefit that can understand really that structure of the present utility model is formed and can be reached, following conjunction with figs. is enumerated embodiment and is described explanation in detail:

The utility model is a kind of composition structure of the chair back, its chair back 10 mainly by chair back plate 1 and backing plate 2 form (as shown in Figure 1), wherein:

Chair back plate 1: the frame groove 11 that is preset with a laying draw-in groove 111.

Backing plate 2: cover and coat housing 21 by cushion 22 and form, the rear end of this housing 21 protrudes out the plural bayonet lock 211 (as shown in Figure 2) of corresponding draw-in groove 111.

By above-mentioned member, make backing plate 2 directly suppress and finish holding and fix with the plural draw-in groove 111 of its plural bayonet lock 211 alignment box grooves 11, the edge part that makes cushion 22 be coated on housing 21 can be sandwiched between between housing 21 and the frame groove 11 (as shown in Figure 3), reaches composition state soft, the mutual cramping of hard.

So as can be known via above-mentioned composition explanation, backing plate 2 is can be via bayonet lock 211 with combining of chair back plate 1, the fixing of draw-in groove 111 design and finishing fast, and cushion 22, housing 21 and to add area with the overlapping of 11 of frame grooves be very little, therefore can significantly reduce the wasting of resources problem that material overlaps in a large number and forms in the known technology, and at chair back plate 1,22 of housing 21 and cushions in conjunction with pattern be adopt soft, the composition design of the mutual cramping of hard, not only can avoid the hypodynamic problem of contact friction of cramping, and can have damping characteristics and improve the effect of adhesion, so steadiness is good, 22 unexpected the disengagings or easy impaired problem of cushion can not take place.

Wherein, the above-mentioned cushion 22 of the utility model can be and directly carries out ejection formation at housing 21 and coat combination, and also the demand of visual actual installation and the cushion 22 made with rubber and housing 21 are formed.

In addition again, can be installed with the adjustment bustle 3 (as Fig. 4, shown in Figure 5) of built-in slide rail 31 in frame groove 11 belows of chair back plate 1, order adjusts that bustle 3 can cooperate different users's build and its height of lift adjustment is adjusted bustle 3 with order and can be supported at user's the small of the back.
