A kind of comfortable chair
Technical field
The utility model relates to chair art, is specifically related to a kind of comfortable chair.
Background technology
During seat design, handrail is a very important part, mainly contains the plane chair back, the waveform chair back in existing design, but all cannot solve back when allowing the long-term maintenance sitting posture of people is really loosened thus the problem felt comfortably cool.
And for example utility model patent, a kind of seat cushion number disclosed in CN 203073754 U has the technical scheme of flexible bar chair: comprise chassis, support bar, pallet, seat cushion, wherein support bar is provided with pedal, described seat cushion becomes the U-shaped of level, and the inner chamber of described seat cushion is provided with many reinforcements.But this utility model does not still have real solution solve back when allowing the long-term maintenance sitting posture of people really to be loosened thus the problem felt comfortably cool.
The chair back of plane is set in prior art usually, such chair back does not have the concavo-convex Curve Design according to human body back so keep sitting posture people cognition not feel well for a long time, the chair sense of discomfort that special right chair one class is lifted and sat is more obvious, prior art is had again to design waist and the back curve of the waveform curve laminating human body of the chair back, but this design is appointed so does not have the curve considering shoulders of human body and tail bone, so keep sitting posture for a long time, tail bone and the shoulder of human body are easily ached.
Cervical vertebra support portion of the present utility model, tail bone support portion, shoulder support portion, the projection that well laminating cervical vertebra is set of waist parcel and dorsal branch support part, the projection of tail bone, the depression of protruding waist of shoulder and the curve of back side, each position of human body back is made to have corresponding support portion to go to support, even if keep sitting posture so for a long time, because human body is that nature leans against on the chair back, back does not have position to need firmly remove position and attitude and keep the demand of the support sense at other other positions, back so whole back is relaxation state, reach long-time sitting posture and also can obtain comfortable technique effect.
