The resting structure is characterized in that a resting structure for waist is arranged on the corresponding position of the backrest frame of the two sides of the chair, the resting structure for waist can support the waist portion of the user, the resting structure for waist can be adjusted up and down on the backrest frame of the two sides of the chair, thereby the resting structure for waist is suitable for the waist portion of every user and has the function of comfortable seating.

Description

The waist of the mesh back of chair tool leans structure

Technical field

The utility model is that a kind of waist of mesh back of chair tool leans structure, refer in particular to a kind of can leaning and construct the waist that leans the support occupant by waist, waist leans the adjustment that the waist height of constructing visual occupant is done the appropriate location simultaneously, to adapt to each occupant state, has the effect of ride comfort.

Background technology

The chair back of general chair tool all is after foam is laid in the front side of wooden backboard that is suitable appearance or plastic cement system backboard, coat leather or table cloth in its appearance again, so the chair back is to adopt solid construction, do not have air permeable effect, so when taking, feel sultry discomfort easily.

The dealer who makes the chair tool improves and produces a kind of chair tool with chair back of good air permeable effect, and it mainly is to set firmly the chair back dictyosome that is netted between chair back skeleton, and chair back dictyosome has suitable elasticity, and the back is more ventilative comfortable when making occupant.Its major defect is:

This chair back structure is except periphery is provided with chair back skeleton, corresponding position in chair back dictyosome all is not provided with any support structure, so easily the occupant lie by the time, lean because of its back lacks strong support, and be easy to generate the situation of having a pain in the back after causing the occupant to take for a long time.

At above-mentioned defective, the inventor is revised improvement, creates the technical solution of the utility model.

Summary of the invention

The waist that the purpose of this utility model provides a kind of mesh back of chair tool leans structure, mainly be to be horizontally set with a waist in the chair back skeleton corresponding position of two sides to lean structure, lean structure by waist and support the waist that leans the occupant, and make waist lean structure can on two side chair back skeletons, carrying out upper and lower displacement adjustment, for the waist location that cooperates each occupant, reach the purpose of ride comfort.

The purpose of this utility model is achieved in that a kind of waist of mesh back of chair tool leans structure, it is characterized in that: the mesh back of this chair tool is to set firmly chair back dictyosome in the space that chair back skeleton institute frame encloses, be horizontally set with a waist between the support body of two sides of this chair back skeleton and leaned structure, this waist leans to be configured in and carries out upper and lower adjustment displacement on this mesh back.

The front side that this waist leans structure is provided with a soft back cushion.Two sides that this waist leans structure respectively are being connected with embedding and are colluding, and these chair back skeleton two side frame body are provided with the adjustment elongated slot, the embedding that this waist leans structure collude corresponding embed to collude establish.

Further specify below in conjunction with preferred embodiment and accompanying drawing.

Description of drawings

Fig. 1 is the schematic rear view of chair tool of the present utility model.

Fig. 2 is the sectional perspective decomposing schematic representation of chair tool of the present utility model.

Fig. 3 be mesh back of the present utility model and waist lean structure overlook the combination cross-sectional schematic.

Fig. 4 is that waist of the present utility model leans the schematic diagram that structure carries out the upper and lower position adjustment.

The specific embodiment

Consult Fig. 1-shown in Figure 3, the mesh back 1 of chair tool 10 of the present utility model is to set firmly chair back dictyosome 12 in the space that 11 frames of the chair back skeleton that is the appearance of suitable frame shape enclose, this chair back dictyosome 12 possesses suitable elasticity, in between the support body of chair back skeleton 11 2 sides, be horizontally set with a waist and leaned structure 2, it mainly is that front side at a body 21 is in conjunction with a rubber-like back cushion 22 that this waist leans structure 2, and respectively be connected with embedding in two sides of body 21 and collude 23, adjustment elongated slot 111 respectively is set in chair back skeleton 11 support body corresponding position second, this adjustment elongated slot 111 is to lean structure 2 embedding for waist to collude 23 and correspondingly embed even establishing, simultaneously, this embedding collude 23 can be in adjusting elongated slot 111 on, following slippage, to adjust the position that this waist leans structure 2, and when the application of force was not adjusted waist and leaned structure 2, this waist leans structure 2 will can displacement.

As shown in Figure 4, when occupant is on this chair tool 10, can adjust the position that this back leans structure 2 earlier, make it corresponding with the waist location after this occupant, when confession occupant's back is posted by mesh back 1, this waist leans structure 2 just can correspondingly support the waist that leans the occupant, makes it more comfortable when taking;

In addition, because of waist lean the structure 2 corresponding occupant's waists end face on be connected with rubber-like back cushion 22, more comfortable in the time of can making waist recline.

Via above explanation, the chair tool of mesh back of the present utility model has following advantage as can be known:

1, since the utility model on the mesh back of chair tool, be provided with waist and lean structure, can be for supporting the waist that lean the occupant, so, can avoid the occupant to take for a long time after, the situation generation of having a pain in the back makes when taking more comfortable.

2, be configured in the end face that corresponding waist reclines and be provided with flexible back cushion because of waist leans, so, more comfortable in the time of can making occupant's waist recline.

3, since waist lean structure can upper and lower adjustment in the adjustment elongated slot of mesh back, so can adapt to waist location after each occupant, suitable facility in the use.

In sum, the utility model really can reach desired use effect, and its disclosed concrete structure not only be not seen in like product, also be not disclosed in application before, have novelty, creativeness and practicality.
