Description
Technical field
The utility model is related to field of furniture more particularly to a kind of chairs with Lumbar regulating device.
Background technology
Inferior health is always problem concerning life of concern, wherein, because sitting gives people the lumbar vertebrae problem brought particularly frequency
It is numerous, it is well known that under human spine is S-type, and the chair back of seat is in the upper and lower straight or chair back now
There is the slight comfort for arching upward to improve chair back support in portion, but the chair of these structures all cannot be to the S type ridges of human body
Column is preferably supported, and the general back-supported angle of chair of these structures is unadjustable, it is impossible to meet individual difference, because
This can not solve the problems, such as the vertebra that sitting is brought to user.
Although the existing chair with Lumbar in currently available technology, under the position of Lumbar is normally in chair
Portion, and the length of Lumbar is shorter, adjustable range is limited, and Lumbar width is wide, it is impossible to be formed to being located at the vertebra in the middle part of human body
Preferable support, influences support effect.
The content of the invention
In order to solve the technical issues of above-mentioned, the purpose of this utility model is to provide a kind of chair with Lumbar regulating device
Son, the adjusting stroke range bigger of the Lumbar of the chair is more prominent to the support of waist, and the effective upper limb that reduces is to lumbar vertebrae
Compressing.

And the upper end for lifting device for folding is fixed by chair back fixing piece with the chair back, lower end is fixed by supporting item fixing piece with supportive body.
Preferably：The height of the cavity is more than the 70% of chair back whole height.Since housing depth is higher,
So that the length of supporting item is larger, and the top of supporting item is hinged with the chair back, so that no matter supporting item is being indulged in overturning
To or horizontal direction on adjustable range it is wider.On the other hand since the length of supporter is longer, therefore even if turned in supporter
When producing to provide lumbar support, human body back can also be leaned on supporter and is more bonded, more comfortably.
Preferably：The chair back front upper is equipped with headrest, and the cavity is arranged on the lower section of headrest, the chamber
The height of body is more than the 60% of chair back whole height.
Preferably：The width of the cavity is the 30%-80% of chair back overall width.Cavity width determines support
The width of body becomes apparent from the support effect of the backbone of human body when supporter is relatively narrow, and when supporter is wider, supporter is to human body
The stress unobvious of backbone, effect are bad.
Preferably：The supporting item includes upper end and supportive body, and the thickness of the upper end is led for support
The 1/4~1/2 of body thickness, and pass through the first cambered surface transition between upper end and supportive body.The structure of supporting item to lift folding
Device can be fixed on the outside of supporting item, part easy to support or the maintenance replacement for lifting device for folding.
Preferably：The folding of lifting is set to two, is respectively positioned between the upper end of supporting item and the chair back, and two
Lift device for folding interval setting.Two are lifted device for folding so that are more stablized during the adjusting of supporting item.
Preferably：The supportive body lower end passes through the second cambered surface transition from the front to the back.With turning over for supporting item
Modulation section, the lower end of supporting item and the contact position of human body waist constantly change, and the lower end of supporting item uses cambered surface transition
It can guarantee that supporting item is bonded always with human body waist, dependence is more comfortable.
Preferably：The shape of the supporting item and the shape of cavity match, and the shape and the chair back of supporting item
Global shape is consistent.
Preferably：The device for folding that lifts is using gas bar or air bag.
The utility model is mounted on by setting cavity on the chair back, and by supporting item in cavity, by lifting device for folding
It is hinged with the chair back, the lumbar support for realizing the chair back is adjusted.
