Abstract

The utility model provides a human body physiological curve chair, which can change people's traditional sitting posture. A seat plate bracket and a knee plate bracket are jointed by bolts or are sheathed or connected with the bracket to form into integration, and the position between an upper sitting plate and a lower knee plate is fitting to the physiological curve of human body sitting posture. The sitting posture of the chair causes an angle of the thighs and the vertebral column to increase, the weight of the upper body is communicated to the knee plate through the bones of the thighs, the muscles on the legs and the back are not under stress, so that the spine is in normal physiology bending state. The chair is used for a long time, the fatigue of people durable sitting working can not only be relieved and the occupational illnesses can be prevented, but also the incorrect youngsters' incorrect sitting posture can be corrected and the body obtains healthy development growth.

Description

The Human Physiology curved chair

The utility model relates to a kind of chair, particularly a kind of chair that meets the Human Physiology curve.At its suitable any age, the people of any height uses.

People's every day and chair are come into contacts with, and the sitting posture of conventional chair is that the people is sitting on the seat, and pin is placed on the ground or is placed on the pedal of front, and waist bears weight above the waist, and vertebra is subjected to force direction opposite with the physiological bending direction.This sitting posture sitting is tired easily, and vertebra is oppositely stressed for a long time, very easily produces fatigue deformation.If things go on like this, not only to being in the teenager who grow up to grow extremely unfavorable (back of the body camel and affect one's power of vision), and also can suffer from occupational diseases such as lumbar muscle strain, the distortion of vertebra dish, cervical vertebra pain, scapulohumeral periarthritis to the adult who is engaged in the sitting posture operation for a long time.Also have shank to produce swelling, tired uncomfortable because of sitting.

The purpose of this utility model is intended to overcome the drawback of above-mentioned traditional sitting posture, from meeting Human Physiology curve and human-body biological engineering mechanics, provides a kind of Human Physiology curved chair.It can be corrected teen-age incorrect sitting posture effectively, keep bodily form healthy development to grow up, and also can not produce fatigue to adult's sitting again and avoid people's sitting and the occupational disease that causes.

The technical solution of the utility model is like this: comprise seat, support, connector, is connected cross-shapedly between the support that seat is installed and the support that lap board is installed with bolt, is seat on it, is that the position between the lap board and the physiological curve of human body sitting posture match down.

Have adjusting lever with teeth between above-mentioned two stands and make active connection.

Have oval concentric reducer adjustment bolt between above-mentioned two stands and make active connection.

Has handrail on the above-mentioned seat support.

The technical solution of the utility model can also be like this: comprise seat, support, connector, the support that seat is installed is the syphon shape integral piece with the support that lap board is installed, it on for seat, be that the position between the lap board and the physiological curve of human body sitting posture match down.

Above-mentioned seat, lap board link to each other with the socket of syphon shape support behind pillar respectively, and this syphon shape support is two that socket links to each other.

Make active connection at each socket connecting place with bolt.

The part that pillar links to each other with support is a siphunculus.

On support, has segmental arc.

Adopt the chair of above technical scheme making, changed traditional sitting posture of people.This sitting posture increases the angle of thigh and backbone, and upper body weight is delivered on the lap board by the thigh bone, and leg muscle and muscle of back are not stressed, so make vertebra be in the normal physiological bending state, make human body very easily keep best sitting posture.Because this chair is by seat and lap board while grantee's body weight, so long-term use, not only can alleviate the fatigue of people's sitting office, study, avoid multiple professional sufferer, raising work, learning efficiency, and correct teen-age incorrect sitting posture and prevent myopia, make health obtain healthy growing, thereby realized the purpose of this utility model.

The utility model is simple in structure, making is easy, with low cost, and can make user's sitting posture of different heights, the different bodily forms meet self physiological curve with regulating through simple between support.As long as it change slightly, can be made into multiple human body physiological curve seat or chaise longue.
