A kind of durable chair
Technical field
The utility model relates to chair art, is specifically related to a kind of durable chair.
Background technology
Chair generally can be provided with rotating function, and chair in use runs into the rotating manner of discontinuity often, and both human body just can not be sat and then rotate chair, and this have the rotating manner of angular force can cause very large impact to the life-span of chair
And for example utility model patent, a kind of bar chair disclosed in number CN 202234035 U, for improve seat support service life and design.Comprise seat support, upper pillar stand, foot-operated circle, lower pillar stand and cup dolly, the surface of described seat support and upper pillar stand is provided with one deck leather or cloth.But the problem that this utility model does not still have the life-span of real solution chair not grow.
The above-mentioned bar chair of prior art, is provided with one deck leather or cloth on the surface of seat support and upper pillar stand, although there is not the phenomenon of painting and coming off because of friction, cannot extend the life-span of the rotating mechanism of chair.If the life problems solving rotating mechanism goes amendment from rotating mechanism itself, need to overthrow Classic couture die sinking again, such cost is huge, and the design defect of the unknown is also not easy prediction and controls, but set about from the matching design of chair itself and rotating mechanism, be more prone to accomplish the effective life-span postponing chair under the prerequisite of controlling cost.
Back pad flap design of the present utility model effectively can say that when people leans against back cushion the twisting at people back and body posture control in certain scope, the design of component flank again can by human body sitting posture state time, on the component flank that the pressure dissipation of buttocks tiltedly rises to side, that a part of pressure becomes non-perpendicular pressure, simultaneously this part dispersed pressure balance human body rotates angular force during chair under each sitting posture state, ensure that the axle center of chair is consistent with actual rotation axle, what rotating mechanism so just can be made to rotate is more smooth, stuck internal part or clamping rotating mechanism when can not act on rotation because of having angular force and life-span of causing declines, extend the service life of chair, simultaneously because the pressure of lower seat is disperseed, chair is to the reaction force of human body being reduced too like this, human body can obtain again the raising of certain comfort level.
