Description
Technical field
The utility model relates to chair art technology, refers in particular to a kind of back of chair structure.
Background technology
Along with the increase of modern's work, reading time, there is the necessary sitting for a long time of many people on seat, and sit excessively for a long time, just make human vertebra cause because body weight is oppressed for a long time human vertebra to produce the grievous injury such as disc herniation, displacement, cause modern to be very easy to occur that the serious sequelae such as sciatica or stiff property spondylitis produces.
Because the problems referred to above, in the streets there are many chair tools can increase a Lumbar again in chair back place at present, make user's waist in time sitting idly be supported, in order to avoid long-time sitting and produce tired sense; In prior art, making support chip without the degree of deformation being applicable to bearing pressure because there is no degree of deformation with the framework of Chair back in locking bottom support chip, producing the support comfortableness of impairment Lumbar.
Utility model content
In view of this, the utility model for the disappearance of prior art existence, its main purpose be to provide a kind of structure simple, be easy to assembling and produce and corresponding degree of deformation can be adjusted according to stressed degree, thus improve the back of chair structure of the comfortableness supported.
For achieving the above object, the utility model adopts following technical scheme: a kind of back of chair structure, comprise support member and Lumbar part, the clamping part that this support member includes supportive body and integrally extended by these supportive body two ends, the Access Division that this Lumbar part includes Lumbar main body and integrally extended by these Lumbar main body two ends, this clamping part and Access Division suitable, this clamping part is installed on Access Division.
As a kind of preferred version, described clamping part is provided with multiple buckle, and described Access Division is provided with multiple draw-in groove, this buckle and draw-in groove one_to_one corresponding.
As a kind of preferred version, described draw-in groove is that Access Division is integrally recessed to form and is provided with a card interface, and this card interface is arranged towards Lumbar main direction by Access Division; Described buckle comprises the projection integrally extended by clamping part and the convex closure raised up by this projection, this projection is extended towards clamping part direction one by supportive body, this projection to stretch in draw-in groove along card interface and is resisted against draw-in groove bottom surface, and this convex closure is stuck on the internal face of draw-in groove.
As a kind of preferred version, each clamping part is provided with two buckles, and described Access Division is provided with two draw-in grooves, this buckle and draw-in groove one_to_one corresponding.
As a kind of preferred version, described supportive body is arcuate body.
The utility model compared with prior art has obvious advantage and beneficial effect, the utility model is by being provided with the support member of arcuate body and the Lumbar part according to ergonomic designs, Lumbar part is installed on the support member of arcuate body, elastic deformation can be there is to different stressed of Lumbar part in it according to different people, improve the degree of deformation of this Lumbar product, thus improve the comfort level of this Lumbar product.
In addition, the connected structure of the utility model to Lumbar product is optimized design, not only structure simple, be easy to production and assembly, and there is good mechanical strength; Its projection to stretch in draw-in groove along card interface and is resisted against draw-in groove bottom surface, and this convex closure is stuck on the internal face of draw-in groove; When Lumbar part is stressed, the interaction of support member and Lumbar part is more firm.

Detailed description of the invention
Please refer to shown in Fig. 1 to Fig. 4, which show the concrete structure of the preferred embodiment of the utility model, this back of chair structure, comprise support member 10 and Lumbar part 20; This Lumbar part 20 is installed on support member 10.
Wherein, this support member 10 clamping part 12 of including supportive body 11 and integrally being extended by these supportive body 11 two ends; This clamping part 12 is provided with two buckles 121.
The Access Division 22 that this Lumbar part 20 includes Lumbar main body 21 and integrally extended by these Lumbar main body 21 two ends, this Access Division 22 is provided with two draw-in grooves 221.
This clamping part 12 is suitable with Access Division 22, and this clamping part 12 is installed on Access Division 22.This buckle 121 and draw-in groove 221 one_to_one corresponding; This draw-in groove 221 is integrally recessed to form for Access Division 21 and is provided with a card interface 2211, and this card interface 2211 is arranged towards Lumbar main body 21 direction by Access Division 22; This buckle 121 comprises the projection 1211 integrally extended by clamping part 12 and the convex closure 1212 raised up by this projection 1211, this projection 1211 is formed towards the one extension of clamping part 22 direction by supportive body 21, this projection 1211 to stretch in draw-in groove 221 along card interface 2211 and is resisted against draw-in groove 221 bottom surface, and this convex closure 1212 is stuck on the internal face of draw-in groove 221.
This supportive body is arcuate body, and this Lumbar main body is the camber body that radian is less, and these supportive body both ends are firmly installed on the both ends of Lumbar main body, and this supportive body forms the larger bit space that allows with by waist main body; The benefit so not only making this Lumbar main body have body mechanics also has good elastic deformation and stress performance, and its structure is simple, powerful, is easy to production and assembly, has market value.
This Lumbar structure can also be applied in the headrest of seat, its effect is identical with the utility model, and when being just applied in headrest, Lumbar main body needs the design changing something or somebody to fall back on into, need to design accordingly according to the head of manpower engineering, work and effect and the utility model roughly the same.
Of the present utility modelly to focus on: the utility model is by being provided with the support member of arcuate body and the Lumbar part according to ergonomic designs, Lumbar part is installed on the support member of arcuate body, elastic deformation can be there is to different stressed of Lumbar part in it according to different people, improve the degree of deformation of this Lumbar product, thus improve the comfort level of this Lumbar product.In addition, design is optimized to the connected structure of Lumbar product, not only structure simple, be easy to production and assembly, and there is good mechanical strength; Its projection to stretch in draw-in groove along card interface and is resisted against draw-in groove bottom surface, and this convex closure is stuck on the internal face of draw-in groove; When Lumbar part is stressed, the interaction of support member and Lumbar part is more firm.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore every according to technical spirit of the present utility model to any trickle amendment made for any of the above embodiments, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
