Description
Technical field
The present invention relates to a kind of office equipment, specifically relate to a kind of computer chair with adjustable lumbar support.
Background technology
Computer has become the important component part of office and family life, computer chair whether reasonable in design, directly affect the healthy of user, the time of working by day be unable to do without computer, go home evening amusement and recreation still be unable to do without computer, sitting discomfort can increase the pressure of user's waist, so the design of computer chair needs in conjunction with work and leisure two kinds of patterns.
At present, on market, most computer chair has the function of adjusting angle of backrest, but is the adjustment of backrest angle, often makes user increase psoas motion because waist is unsettled, makes the waist stress of user and feel uncomfortable.
Recently, part computer chair has set up air bag in the nearly waist position of backrest, the function supporting waist can be played, but, the air bag supporting waist can not change along with backrest angle and stretch, namely when backrest angle changes, there will be the phenomenon that waist is unsettled or part is unsettled, thus reduce the comfortableness of user.
Summary of the invention
The technical problem to be solved in the present invention is for overcoming the defect that cannot regulate without lumbar support or lumbar support existing for computer chair of the prior art, and provide a kind of computer chair with adjustable lumbar support, it makes backrest when rotating by the design of adjustable lumbar support, lumbar support can fit tightly waist, there will not be unsettled or that part is unsettled phenomenon.
The computer chair with adjustable lumbar support of the present invention, comprise seat support, backrest and be placed in the chair leg of seat support bottom, backrest controls it by knob and rotates forward or backward, rear support is in the back of backrest, the the first elastic packaging bag both be connected is provided with between backrest with rear support, bottom backrest deviating from the side of rear support is provided with the second elastic packaging bag, be respectively arranged with the first air bag, the second air bag in first elastic packaging bag, the second elastic packaging bag, be connected between the first air bag and the second air bag.
Preferably, be provided with copper air valve between described first air bag and the second air bag, the adjustment cap of copper air valve is stretched out from backrest side, and the both sides of copper air valve are communicated with two air bags respectively by emulsion tube.
The computer chair with adjustable lumbar support of the present invention, shows relative to the beneficial effect of prior art:
Set up rear support by the back at backrest, and between backrest and rear support, backrest surface arranges an elastic packaging bag respectively to the side of human body waist, and be designed with the air bag be connected in two elastic packaging bag.Thus the defect that cannot regulate without lumbar support or lumbar support overcome existing for traditional computer chair, it makes backrest when rotating by the design of adjustable lumbar support, and lumbar support can fit tightly waist, there will not be unsettled or that part is unsettled phenomenon.This computer chair has market application foreground widely, and has higher economic interests.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the present invention.
Fig. 2 is the structural representation of the computer chair of backrest angle when changing.
Fig. 3 is the annexation schematic diagram between two air bags.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in further detail.
A kind of computer chair with adjustable lumbar support shown in Fig. 1 and 2, it comprises seat support 10, backrest 18 and is placed in the chair leg 11 of seat support 10 bottom, backrest 18 controls it by knob 14 and rotates forward or backward, seat support 10 is furnished with corium or dry goods cushion 12, the both sides of cushion 12 are provided with handrail 13, and the top of backrest 18 is furnished with headrest.
In order to overcome the defect that cannot regulate without lumbar support or lumbar support existing for existing computer chair, the present invention has additional rear support 16 at the back of backrest 18, simultaneously, the the first elastic packaging bag 17 both be connected is provided with between backrest 18 with rear support 16, bottom backrest 18 deviating from the side of rear support 16 is provided with the second elastic packaging bag 20, be respectively arranged with in first elastic packaging bag 17, second elastic packaging bag 20 between first air bag 15, second air bag 21, first air bag 15 and the second air bag 21 and be connected.
When backrest makes it rotate backward gradually by normal 90 degree by knob 14, because two air bags are communicated with, so make the first air bag 15 shrink by backrest 18 and rear support 16 extruding and gas in capsule pressed in the second air bag 21.Due to the increase of backrest angle, leaning against the support volume that the waist location on backrest relies on can increase, and the second air bag 21 now expanded can just meet such needs.
When backrest makes it be rotated to normal condition (as 90 degree) gradually by heeling condition by knob 14, because two air bags are communicated with, in described second air bag 21, unnecessary gas can flow in the first air bag 15, until two air bag internal gas pressure balances.
Certainly, rear support 16 both can have been installed fixing with seat support 10, also can be realized it by the control assembly that such as above-mentioned knob 14 structure is identical and rotate, as long as meet when backrest 18 rotates backward and the first air bag 15 extrudes by backrest 18.When rear support 16 and seat support 10 are installed fixing, angle between the two can be designed to 120 degree, so just can meet normal user demand.
In order to more reasonably control the flow direction of gas between two air bags, the present invention is provided with copper air valve 22 between described first air bag 15 and the second air bag 21, the adjustment cap of copper air valve 22 is stretched out from backrest 18 side, as shown in Figure 3, the both sides of copper air valve 22 are communicated with two air bags respectively by emulsion tube 23.When the angle of backrest needs to regulate, then open copper air valve 22, according to said method, backrest is rotated forward or backward.After the angular adjustment of backrest completes, then close copper air valve 22.
Of the present invention have in the structure of the computer chair of adjustable lumbar support, and the length of rear support 16 does not also limit, as long as can meet assembling first elastic packaging bag 17 and the first air bag 15 does not affect the attractive in appearance of computer chair entirety.The volume size of two air bags does not need special restriction yet, as long as make the second elastic packaging bag 20 of the second air bag 21 outside can support human body waist and do not occur that part is unsettled.
Above-mentioned just in order to technical conceive of the present invention and feature are described, its objective is and be one of ordinary skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.The change of every equivalence done by the essence of content of the present invention or modification, all should be encompassed in protection scope of the present invention.
