Description

A kind of chair that is used for belly support/support leans on

Technical field

The present invention relates to the apparatus of taking one's seat, comprise the apparatus of taking one's seat of environment such as household, office, enterprise and public place, especially provide a kind of chair that is used for belly support/support to lean on.

Background technology

A lot of people will tide on chair nearly tens hours of every day, along with popularizing of computer/network, this troop also is growth trend, people are often perplexed by aching pain in waist and back, the number of suffering from vertebra (comprising cervical vertebra, thoracic vertebrae, lumbar vertebrae) disease is also constantly soaring ... though between not talkative these phenomenons direct positive connection is arranged, undeniable, it has stronger correlation.Why can this most common body shape produce many harmful effects to health?

The specialty data generally believes that incorrect sitting posture is one of key factor that causes above-mentioned bad reflection.When bend over one's desk working, when study, amusement, egress of chair backrest often above the waist, forward lean, the center of gravity reach, human vertebra is in spite of oneself and is unfavorable for healthy physiology and appearance, causes the muscle group at neck and back to be in tension; Keep this sitting posture for a long time, above-mentioned muscle group can be elongated gradually, and convergent force is corresponding to be weakened, certain position meeting overload of unconscious vertebra, in the course of time, then can cause body part discomfort or aching pain in waist and back, also can bring out spur what is more or cause the deformity of spinal column.

At the problems referred to above, some patented technologies are started with from the structure of chair and have been done corresponding improvement, as Chinese patent:

ZL97233396.7 provides a kind of posture correcting chair, and it is made of chair frame and seat, no backrest.The chair frame has the front fork of two fork blades, the back vent that two back vent legs between fork blade are arranged that turns forward and the adjusting screw that is installed in therebetween to constitute by sweptback.Seat tilts to be fixed on front fork top.The knee plate is being fixed on back vent top.Its height is regulated by adjusting screw.

ZL99251180.1 provides a kind of variable balance chair, comprise seat, support and backrest, the back seat regulating sleeve bar that it is characterized in that support can realize that with the back support rod employing connected mode of lifting is connected, seat adopts positioning embedded connected mode to be connected with support, the corresponding support of knee shank place when the stressed pad of knee leg is fixed on and takes a seat with human body.

02808286.9 providing a kind of eliminates because the method and the chair of the motionless problem that causes of sitting, in the method, when being seated, by lateral parts (3,5) people's that is seated of supporting pelvis and leg muscle, described lateral parts to small part is bent downwardly, and forms a shape of a saddle seat part.The lateral parts (3,5) of described seat part (13) is formed by at least two parts, has formed between them along seat part (13) central opening longitudinal.

Above patent is suppressing aspect the spinal curvature different characteristics are arranged respectively, and it is compared with conventional chair, and sitting posture has had some adjustment or improvement under certain particular case, exists complementarity between above-mentioned patented technology and the conventional chair.Because conventional chair mainly is to be support with buttocks, back, and people are difficult to keep not egress of chair backrest of health for a long time when bending over the desk, so often be difficult to keep vertebra to be in the sitting posture of standard state for a long time; Two patents of aforementioned ZL97233396.7 and ZL99251180.1 adopt the support of shin bone and buttocks lower inclined plane seat support, the physiology and appearance of vertebra can have certain improvement when bending over the desk, but comfortableness is relatively poor, especially lower limb are subjected to certain limitation, because of being in the supporting stress all the time, shin bone glides to prevent health, and the free degree of upper body is excessive, so be very easy to tired.Patent 02808286.9 is also for eliminating tired and solving that vertebra form problem designs when taking one's seat, it improves seat support, but still fail to solve well the excessive muscular fatigue problem that very easily causes of the upper body free degree with aforementioned patent is the same, and its corresponding again burden that increases the weight of foot/shank also easily causes fatigue because foot/shank is not easy to alter one's posture.
