Specific embodiment
For technology contents, the construction feature, the effect realized that the utility model is described in detail, below in conjunction with embodiment
And attached drawing is cooperated to be explained in detail.
As shown in Figure 1 and Figure 2, the utility model chair back waist support linkage mechanism 100 includes leaning against 1, Lumbar 2 and linkage unit,
The linkage unit back support 3 and lumbal branch support 4, the back support 3 and lumbal branch support 4 are of an L-shaped structure, the back support
The 3 plate-like structure in upper part and it is located at the rear side leaned against, and leans against 1 with described and be fixedly connected；The back support 3
Lower part in two leg-like structures 3a and be located at it is described lean against 1 lower section two sides, and extend to lower section and the seat of the seat 200
Chair 200 is pivotally connected, and forms pivoting point A.The Lumbar 2 is located at the lower section for leaning against 1 and two leg for being located at the back support 3
Between structure 3a.It is described to lean against 1 with the Lumbar 2 in integrated formed structure, and the junction for leaning against 1 Yu the Lumbar 2
Interconnecting piece 5 equipped with bent deformation；The middle part of the Lumbar 2 and the upper end of lumbal branch support 4 are slidably connected, the waist
Support 4 is set among the rear side of the Lumbar 2, and the lower end of the lumbal branch support 4 is fixedly connected with the seat 200.
As shown in figure 4, the interconnecting piece 5 offer it is several in the slot 51 being laterally arranged.By the way that the slot 51 is arranged, make institute
It states interconnecting piece 5 and forms flexible thin plate-shaped structure, so that the interconnecting piece 5 can realize that thin plate deforms.Adjacent two institute
State formation dentalation 52 between slot 5.Certainly, the interconnecting piece 5 or the plastic cement that there is elasticity or can bend repeatedly
Component, it is only necessary to reach deformable bending when in use, can reset can't occur the damage phenomenon such as fracture when not in use,
It is not limited with above structure.
Again as shown in Figures 2 and 3, projecting block 22 is highlightedly equipped in the middle part of the rear side of the Lumbar 2, on the projecting block 22
Sliding slot 21 is offered, the upper end of the lumbal branch support 4 is equipped with the pin shaft 41.The pin shaft 41 is slidably plugged in the sliding slot 21
In.By the cooperation of the sliding slot 21 and the pin shaft 41, the Lumbar 2 can be enable to support 4 slidably engaged with one another with the lumbal branch
Connection, to make Lumbar 2 when leaning against 1 movement while swing, realizes the purpose of linkage.
In conjunction with Fig. 3, when user be seated on seat 200 and back bear against it is described when leaning against 1, it is described to lean against 1 in backward
Swing is faced upward, the back support 3 is counterclockwise swung, meanwhile, 1 lower end of leaning against drives the Lumbar 2, at this moment described
Lumbar 2 is swung by the sliding slot 21 and being slidably matched for pin shaft 41, finally, the pin shaft 41 is from the sliding slot 21
One end slides into the other end, and the interconnecting piece 5 occurs flexible deformation and bends, so that it is in lean against 1 to described that the Lumbar 2 is whole
Front side is prominent and is affixed on the waist of user, at this moment, described to lean against 1, Lumbar 2, back support 3 and lumbal branch support 4 and reach between each other
To stable state, described to lean against 1 and provide support force by back support 3 for the back of user, the Lumbar 2 is user's
Waist provides support force, to alleviate the discomfort of waist.
Compared with prior art, due to the utility model it is described lean against 1 lower end be arranged a Lumbar 2, make the Lumbar 2
1 is leaned against in integrated formed structure with described, and is leaned against 1 described and be equipped with interconnecting piece 5 with the junction of the Lumbar 2, and make institute
It states Lumbar 2 to be slidably connected with lumbal branch support 4, so that 1, Lumbar 2, back support 3 and the lumbal branch of leaning against supports 4 shapes
At a link mechanism, then the characteristic by can flexibly bend deformation using the interconnecting piece 5, therefore, when the human body back
When leaning against 1 described in bearing against, using the linkage of this linkage structure, make the bending of interconnecting piece 5 deformation, so that the Lumbar
2 protrude from it is described lean against outside 1, thus and human body waist closer to providing a support force for human body waist, greatly improve waist
The comfort in portion；Entire mechanism be the breasting with human body and making lean against 1 and Lumbar 2 deform simultaneously, without manual operation tune
Section, structure is simple, easy to use.
In addition, the described of the application leans against 1 other forms also can be set into the junction of the Lumbar 2, for example, can
To lean against described between 1 and the Lumbar 2 in rotationally connection or by silica gel connection, the linkage again may be by
Component makes opposite bending between the two, and equally reaching makes the Lumbar 2 relatively described to lean against 1 prominent forward and support waist.
Above disclosed is only the preferred embodiments of the utility model, cannot limit the utility model certainly with this
Interest field, therefore equivalent variations made according to the patent scope of the utility model still falls within the utility model and covered
Range.
