Abstract
The utility model comprises a hard bottom plate, which has a front surface, the front surface is slightly convex at the longitudinal part, and a concave arc surface is formed at the transverse part, and the front surface of the hard bottom plate is provided with a buffer material and a filling material, the combination form of the buffer material and the filling material can be overlapped or side by side or other combination forms, and the front surface of the hard bottom plate can be completely covered or arranged at intervals on the front surface of the hard bottom plate by the buffer material and the filling material, and finally, the hard bottom plate is accommodated in a coating body; when a user leans on the cladding body, the back of the user can sink into the concave cambered surface, and the lumbar vertebra, the thoracic vertebra and the cervical vertebra can be supported by the convex curved surface of the hard bottom plate and the filling material and the buffer material, so that the force of the user lying down instantly is absorbed by the filling material and the buffer material, and the pressure is dispersed and reduced. Therefore, the hard bottom plate provides strong and stable supporting force, and the phenomenon that the back lying force is too large to cause injury or discomfort is avoided.
Description
Technical field
The utility model relates to a kind of back cushion plate structure, be meant that especially a kind of moment strength when lying after with the user by hard base plate and fender absorbs, and support by hard base plate and fender lumbar vertebrae, thoracic vertebrae and cervical vertebra with the user, when avoiding the user to sit, the back cushion plate structure of uncomfortable situation takes place in its back.
Background technology
Press, the user who generally needs sitting on seat, to handle official business, big city buys the support of back cushion as the vertebral curve at waist or back, to reach the purpose of long-time comfort for sitting posture.
But commercially available back cushion is of a great variety, the back cushion of direct imitation human vertebra curve plotting is arranged or have the back cushion of guiding mechanism, yet commercially available back cushion has following shortcoming at present:
1. because everyone stature and sitting posture are neither together,, can't accurately reach support effect out of the ordinary if buy the back cushion of copying the human vertebra curve.
2. back cushion commonly used mainly be with foam as supporter, if foaming is cotton partially firmly the time, its buffering effect is limited, and the user can because of after the strength of lying too big, and cause the injured facts in back easily, and after prolonged the leaning on of foaming material that should be hard partially, also allow the user back produce discomfort easily.
3. when soft partially as if the foaming cotton, though have good buffering effect, user's back can be sunken in the foaming material, and then causes the not convenient property of user in activity.
This shows that above-mentioned article commonly used still have many shortcomings, real non-one kindhearted design, and demand urgently being improved.
Every shortcoming that the utility model applicant derives in view of above-mentioned back cushion is urgently to think to be improved innovation, and after concentrating on studies through taking great pains to attain one's goal for many years, successfully this part back cushion plate structure is finished in research and development finally.
The utility model content
The purpose of this utility model is to provide a kind of back cushion plate structure, is the use of the shape collocation fender of the front end surface by a hard base plate, lumbar vertebrae, thoracic vertebrae and the cervical vertebra appropriateness at user back is supported, to reach the purpose that comfortable seat is lain.
Of the present utility model time a purpose is to provide a kind of back cushion plate structure, is to absorb the strength that the user lay after moment by a fender, avoids user's health to come to harm.
Another purpose of the present utility model is to provide a kind of back cushion plate structure, is that the front end surface at hard base plate is provided with fender and fills material, strengthens the purpose that the back is supported to reach.
Can reach the back cushion plate structure of above-mentioned utility model purpose, include a hard base plate, fill material, fender and cladding; Wherein, this hard base plate has a front end surface, this front end surface is the convex surface that slightly becomes a projection at vertical position, and laterally the position is formed with a cancave cambered surface, and with fender and fill material and be incorporated on the front end surface of hard base plate, this fender and fill the front end surface that material can be covered with the front end surface of hard base plate or be arranged at intervals at hard base plate, and this buffer body and the combining form of filling material can be and overlaps or side by side or other combining form, at last, hard base plate is placed in the cladding; When lying at the cladding surface behind the user, user's back is sunk in the cancave cambered surface of hard base plate, lumbar vertebrae, thoracic vertebrae and cervical vertebra place then are subjected to hard base plate convex surface and fender and fill the support of material, to reach the correct comfortable purpose of lying and leaning on, and by fender and fill the strength that material absorbs moment when disperseing to lie behind the user, avoid the user because of after lie that strength is too big, to cause health to take place injured; And providing strong and stable support force by hard base plate, the strength of lying after avoiding is too big, causes the generation of injured or the uncomfortable facts, to reach the purpose that comfortable seat is lain.
Advantage of the present utility model and technique effect are:
Back cushion plate structure provided by the utility model when comparing mutually with other common technology, has more following advantage:
1. the utility model is the use by the shape collocation fender of a hard backplate surface, with lumbar vertebrae, thoracic vertebrae and the support of cervical vertebra appropriateness at user back, to reach the purpose that comfortable seat is lain.
2. the utility model is to absorb the strength that the user lay after moment by a fender, avoids user's health to come to harm.
3. the utility model is provided with fender and fills material at hard backplate surface, strengthens the purpose that the back is supported to reach.
