Description
Technical field
The present invention relates to a kind of Ergonomic chair.
Background technology
The fierceness day by day of the quickening of modern life rhythm, social competition and the rise of Internet technology are popularized, when increasing people is long even overtimely be engaged in intellectual work before being sitting in desk.A lot of youthful study, amusement, doings also all launch on the internet.No matter in office or stay at home, be sitting in that not fight one battle after another before the computer be a lot of youthful customs with not going other place.Cambridge Jia becomes the normality that the modern lives.According to nearest statement-of-health analysis, be sitting in for a long time design unreasonable, sit on the uncomfortable work chair inferior of sense, can influence the blood of human body circulation, destroy the digestion running, upset human body metabolism, also can threaten bone health, cause multiple diseases such as cervical spondylopathy, lumbar vertebra disease, scapulohumeral periarthritis, wrist vasculitis.This shows that correct comfortable sitting posture and a high-quality comfortable work chair are extremely important for health.
Along with development of technology, sitting posture also will become the main working method of Future in China labourer.Is sitting posture exactly that we often say? individual 90 degree, 1 central point Dou Ying is stood tall and upright, and to kowtow the celestial Che pain of Nai Baomeng gorge Jing Po lame for He guilt coffin Zhai vermachen 3 swollen even sulphurs? the angle of 0 to 105 degree supports whole upper body in mode the most easily, alleviates lumbar vertebrae pressure; When being seated be the thigh of tie point and the angles that shank should keep 90 to 105 degree with the knee, promptly thigh wants level in ground, and shank will be perpendicular to ground, makes shank can share supporting role to health, thereby alleviates the support load of buttocks; Should keep the angles of 90 to 105 degree with elbow as the upper arm of tie point and forearm when using keyboard, and obtain appropriateness and support, so avoid shoulder excessively to alarm or stay and cause and take on Zhou Bushi.User's head should excessively not lean forward or swing back, be advisable to erect naturally, eyes are looked squarely forward, look squarely sight and should fall within the center of computer screen or position slightly on the upper side, can not too face upward or nutation, to avoid bringing unnecessary load, the distance of an arm left and right sides length should be arranged between screen and the eyes to cervical vertebra.User's height, brachium, leg length, body weight, build etc. all are not quite similar, and therefore, a good work chair should have abundant controllability flexibly, promptly can require custom to carry out the details adjustment according to environment for use and individual.The comfortable seat of health will correct faulty sitting posture for slowing down fatigue and neurothlipsis, and the prevention cervical vertebra improves eyesight, and the protection waist supports elbow joint, and whole body loosens and plays an important role; The tradition office chair can not satisfy and prevent numerous health problems of exposure day by day already.
Summary of the invention
The object of the present invention is to provide a kind of Ergonomic chair, the angle of this Chair back and curved surface can be regulated and neck, back and waist are had good supporting.Solve the comfort level of back, neck and waist, alleviated the fatigue strength of thoracic dorsal vertebrae, neck bone and lumbar vertebra, thereby improved the comfortableness of human body sitting.
Its solution is: a kind of Ergonomic chair, comprise the chair back and chair back rack, it is characterized in that: described chair back rack upper cross is provided with the rotating shaft that leading flank has the arc backup plate, the both sides, middle part are respectively arranged with the shoulder active plate of the slippage on horizontal and vertical of chair back rack relatively, the both sides, bottom are provided with the back active plate of the slippage on horizontal and vertical of chair back rack relatively respectively, are provided with relatively chair back rack slippage waist adjustment securing member at fore-and-aft direction and vertically in the middle of the bottom; Be provided with back stick Soft Roll in the middle of the described chair back rack.
The invention has the advantages that:
One,, perhaps there is partial design to regulate (promptly being that single local waist or neck are regulated) at many designs fix of existing market chair back formula.A lot of fixed neck braces often are not in the position that the user needs; The fatigue strength of the height of neck brace and angle decision user cervical vertebra, reasonably the neck brace height should be transferred neck brace in the 3rd of cervical spine and save the 7th joint so that make cervical vertebra obtain necessary support, effectively removes the fatigue of cervical spine.
The present invention has the four big strong points to human body back, neck and waist on the chair back:
1. adjustable arc backup plate can be realized the support to the lordosis cervical vertebra.
2. the back active plate can be realized the support to the protruding thoracic vertebrae in back.
3. waist adjustment securing member can be realized the support to the lordosis lumbar vertebrae.
4. the shoulder active plate can be realized the support to shoulder.
These supports can guarantee that the user is sitting in the natural curve that keeps backbone when sitting straight on the chair, has avoided the appearance of deformity of spinal column situation.
Two, the design of " W " shape is adopted at seat cushion middle part, and the edge adopts the waterfall type Flexible Design, leans forward or during the hypsokinesis health, can discharge lower leg and thigh pressure the user, promotes the lower limb blood circulation, and can not produce the sensation that skids off seat.
Do not feel well because skin surface humidity increases at present sitting people regular meeting.For the male sex, if the gas permeability of seat-cover fabric is bad, long-time lower body part is airtight, causes prostatitis and scrotitis easily.For the women, cause gynecological diseases such as colpomycosis easily.So chair should have release action to humidity, do not block the steam disperse that heat circulation or hot body produce.At present common on the market seat material uses leather, composite plastic, sandwich eyelet fabric several usually; Leather seat cushion totally enclosed type parcel, ventilative poor; Problems such as being not easy of screen cloth and weaving face fabric keeps clean, and be dirty easily.The present invention adopts ventilative grizzly bar design on cushion, has the good ventilation air permeable effect, and is promptly attractive in appearance practical again.
