A kind of comfortable seat
Technical field
The utility model relates to chair art, is specifically related to a kind of comfortable seat.
Background technology
During seat design, handrail is a very important part, mainly contains horizontal bar shaped handrail in existing design, without the handrail of handrail and certain radian, but all cannot solve and allows the arm of people really obtain the problem loosened.
And for example patent of invention, a kind of chair disclosed in number CN 202234035 U, it possesses the resinous backrest with multiple elongated hole, and it is set to such structure, and elongated hole possesses: the wide width part with the wide part extended in the longitudinal direction; With continuous in this wide width part roughly wide the narrow width part being formed, extend in the longitudinal direction.But what this invention did not still have a real solution arm shelves uncomfortable problem.
The bar shaped handrail of level is set in prior art usually, people is allowed to obtain comfort successively, and this design not naturally droops but will keep certain angle due to the arm of human body, elbow joint directly can touch the harder surface of handrail simultaneously, and wrist also well cannot adjust posture, keeping the arm of the descendant of sitting posture can feel uncomfortable for a long time; Or handrail cancelled by some seat, staff can be put nowhere, and with it can only being placed on, the shoulder of long-time descendant can not feel well; Again or some seat adopt the handrail of certain radian, but radian is not by designing, and the chair back does not coordinate yet the Curve Design of this radian handrail, cause still solving the tight sense of people's shoulder to bicipital muscle of arm place, thus uncomfortable problem.
Described top of the present utility model changeover portion, changeover portion of the described end, described interior to pars convoluta, described export-oriented pars convoluta, described vertical arm rest section and the described straight setting to arm rest, people's problem that arm can well be placed nowhere when normal sitting position can well be solved, because this set meets the curve everywhere of the arm of human body, the arm of the such people also reliable point and obtain comfort when natural relaxation, described top changeover portion simultaneously, changeover portion of the described end, described interior to pars convoluta, described export-oriented pars convoluta, described vertical arm rest section and described directly to arm rest all with the 4th radian by the direction, the back side of the described chair back towards frontal with the 4th bending curvature, coordinate the bending of the 4th radian that human body back just in time can be coordinated to the curve at shoulder place, and when human body can not be caused firmly to lean against a plane, with this, further comfort is obtained to the constriction of back.The demand that when described interior changeover portion, described outer changeover portion and the setting of described support pars convoluta have just in time coordinated human body forearm square, wrist is sagging, such people adjusts the posture of forearm with regard to available mistake oneself and obtains comfort, and the curve that page laminating human buttock is set of the 6th radian, disperse the downforce of buttocks and obtained comfort further.
