Abstract
The utility model provides a back cushion structure. The back cushion structure comprises a cushion body, wherein the cushion body is provided with a backrest part contacted with the back of a human body, a waist rest part contacted with the waist of the human body, and an abutting part contacted with the crotch of the human body. A bent arc shape is represented generally by adopting a human engineering design so that the waist rest part and the backrest part of a cushion form a mutual acting force under the effect of gravity when the cushion is placed in a seat lean against the human body; an elastic load of the cushion uniformly leans against the human body so as to realize the effects of correcting sitting postures, naturally supporting and optimally and comfortably leaning.
Description
Technical field
The utility model relates to a kind of daily living article field, especially a kind of back cushion structure.
Background technology
Back cushion is often contact in people's daily life, work, is applied on the backrest of the things to sit on such as chair, sofa more.Traditional back cushion is all machine-made structure, such as vertical stratification, incline structure, these structures mainly play the dependence effect of back and waist, but these structures do not meet ergonomic designs, not only make people take a seat that after sensation is felt bad but also can exert an adverse impact to the vertebra of human body, lumbar vertebrae and cervical vertebra.The long-term thing to sit on of this structure that uses easily makes people suffer from chronic lumbar vertebrae disease.Current existing back cushion structure is most of only to be protected for lumbar vertebrae, other vertebra positions is not designed, and therefore uses comfort level lower, and sitting meeting allows people produce sense of fatigue.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of back cushion structure that meets the curve engineering design of human body back is provided.
A kind of back cushion structure described in the utility model, comprise back cushion body, described back cushion body has the butting section of a portion that leans against contacting with human body back, a waist relying part ,Yi Geyu human body crotch contact contacting with human body waist, on back cushion body, be provided with hole clipping and slotted eye, the side of back cushion body is curved arc shape, wherein lean against portion by both sides cave inward, waist relying part is that arc surfaced therefrom outwards swells to both sides, butting section is caved inward by both sides, described back cushion body two middle side parts are provided with hole clipping, and the slotted eye on described back cushion body is regularly arranged.
Further, the portion that leans against of described back cushion body, waist relying part and the butting section structure that is formed in one.
Further, the compare Hou，Wang center, both sides of described back cushion body gradually attenuation be prominent arcuation.
Further, the slotted eye on described back cushion body is no less than 2, and the arrangement of slotted eye is shape axisymmetricly.
Further, the back of described back cushion body is provided with groove lines.
A kind of back cushion structure described in the utility model, by adopting ergonomic designs totally to present curved arc shape, make back cushion be seated in seat inner face for human body while reclining, the waist relying part of back cushion and the portion of leaning against are subject to resting on of human body back to form interaction force under Action of Gravity Field and make the elastic load of the back cushion human body that evenly reclining, and to reach to have, correct faulty sitting posture and natural support and bestly take suitable dependence effect.
