Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide it is a kind of using it is comfortable, clothing does not occur
The multifunctional chair backrest of object fold.
To achieve the above object, the utility model provides following technical solution: a kind of multifunctional chair backrest, including net
Back, Lumbar, upper bracket and lower bracket, the lower bracket are mounted on seat plate, and the upper bracket is slidably mounted on lower bracket,
The net back and Lumbar are rotatably installed on upper bracket, and Lumbar is located at the centre of net back, setting in the upper bracket
There is sliding groove, the lower bracket is slidably mounted in sliding groove, is equipped with spring in the sliding groove, is made by the elastic force of spring
With enabling upper bracket to slide on lower bracket.
The utility model is further arranged to: the L-shaped setting of lower bracket, and one end of lower bracket level and seat plate connect
It connects, vertical one end is slidably installed with upper bracket.
The utility model is further arranged to: the T-shaped setting of upper bracket, the both ends of upper bracket level and net back rotation
Connection, the sliding groove are arranged on the vertical one end of upper bracket, and the vertical one end of the lower bracket and sliding groove cooperate.
The utility model is further arranged to: the net back is arranged in frame-type, the horizontal both ends of upper bracket and the two of net back
Vertical frame side rotation connection nets rotation between the lower end horizontal pane side of back and the vertical end of lower bracket and is provided with the first elasticity turn
Axis.
The utility model is further arranged to: rotation is provided with the second elasticity between the Lumbar and the vertical end of upper bracket
Shaft.
The utility model has an advantage that through the cooperation between net back and upper bracket, so that improving the use of seat
Comfort and clothing fold can not occur, lumbar support when human body is sat on the seat can be improved by the setting of Lumbar
Power further increases seat comfort, can be after human body leaves seat by the setting of spring, and upper bracket passes through spring
Elastic force effect is returned to home position.
Detailed description of the invention

Specific embodiment
Shown in 3, a kind of multifunctional chair backrest of the present embodiment, including net back 1, Lumbar 2, upper bracket 3 and under
Bracket 4, the lower bracket 4 are mounted on seat plate, and the upper bracket 3 is slidably mounted on lower bracket 4, the net back 1 and waist
It is rotatably installed on upper bracket 3 by 2, and Lumbar 2 is located at the centre of net back 1, is provided with sliding groove in the upper bracket 3
5, the lower bracket 4 is slidably mounted in sliding groove 5, is equipped with spring 6 in the sliding groove 5, is made by the elastic force of spring 6
With enabling upper bracket 3 to slide on lower bracket 4.
The L-shaped setting of the lower bracket 4, the horizontal one end of lower bracket 4 are connect with seat plate, vertical one end and upper bracket
3 are slidably installed.
The T-shaped setting of the upper bracket 3,1 rotation connection of the horizontal both ends of upper bracket 3 and net back, the sliding groove 5 are arranged
On the vertical one end of upper bracket 3, the vertical one end of the lower bracket 4 and sliding groove 5 cooperate.
The net back 1 is arranged in frame-type, and the horizontal both ends of upper bracket 3 and two vertical frame sides of net back 1 are rotatablely connected, net back
Rotation is provided with the first elastic rotation shaft 7 between 1 lower end horizontal pane side and the vertical end of lower bracket 4.
Rotation is provided with the second elastic rotation shaft 8 between the Lumbar 2 and the vertical end of upper bracket 3.
By using above-mentioned technical proposal, when human body leans against net 1 layback of back, net back 1 is made with upper bracket 3 by the strength of human body
Net 1 slide downward of back, because there is the reason of the first elastic rotation shaft 7 is pullled while net 1 slide downward of back, and net on back 1 partially with
The junction of upper bracket 3 generates rotation, makes partially to slide backward under net back 1, and upper bracket 3 is because of the upward power of support by spring 6,
Keep the back sense of net back 1 more preferable, while the human body back thrust of waist position moves Lumbar backward, and passes through the second elastic rotation shaft
9 elastic force acts on so that the human body waist also support by Lumbar 2.Human body leans against on net back 1 when swinging back simultaneously, because net back 1 with
The synchronous layback of the back of people, the clothes of back will not purse up.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
