Abstract
A seating device comprises a seating surface and a backrest with a rotary device. The rotary axial line of the backrest is positioned on the place which is 5-20 centimeter ahead the most anterior of the contact place of the back and the backrest and within the range between 0-10 centimeter higher than the seating surface and the rim of a soft cushion of the seat. The design essential of the utility model is that the rotation axis of the backrest is arranged basically in coincidence with the rotation axis of the human hip. When people lean back along with the backrest, a relatively great sliding between a human back and the backrest can be prevented, thereby the position of the comfort point of the backrest keeps accurate and the coats of users cannot be hauled upward so that the comfortable degree of people is increased.
Description
Technical field
The new shape of this practicality relates to a kind of tool, particularly a kind of seat tool that has the rotation backrest.
Background technology
In the present chair that has rotatable back, the sofa in uses such as automobile, aircraft, offices, the common feature of its backrest rotation is: the rotating shaft of backrest is positioned near backrest and the position that the seat plate face combines, this class backrest when reclining backward, backrest can not with the same moved further in people's back.This is because mostly the reclining design of chair or sofa backrest is from the angle that makes the backrest adjustable inclination, the hip joint pivot center skew of the rotation of its backrest and human body is bigger, the user is at health backward during reclining, backrest and human body back produce bigger slippage, drag and make on user's the last clothing, also can cause the position deviation of the comfortable point of backrest, bring discomfort to the user.
