The specific embodiment

The present invention is described in further detail below in conjunction with drawings and Examples.

As Fig. 1, the chair that present embodiment disclosed mainly is made up of three parts: cushion portion 11 and rest portions 12 and support portion 13, and wherein adopt axle 14 to connect between cushion portion 11 and the rest portions 12.Cushion portion 11 and rest portions 12 are formed by inside and outside two parts.Skin is the overcoat of being made by retractility and all reasonable material of gas permeability, and the overcoat volume depends on the cumulative volume of inside stuffing, and the overcoat shape is cut out according to the ergonomics curve.Inside stuffing is made up of a kind of hollow bead of inflation.

As Fig. 2, according to mechanics principle,, this power can be decomposed into two the power N1 and the N2 of quadrature so if spherical object A0 is subjected to a downward pressure N, its magnitude relationship satisfies ^N=^N1+^N2, and wherein N1 and N2 show as the oblique pressure that is applied on spherical object A1 and the spherical A2.And spherical object A2 pressure N2, as shown in Figure 3, pressure N2 can be decomposed into the power N2x of horizontal direction and the N2y of vertical direction, and its magnitude relationship satisfies ^N2=^N2x+^N2y.According to Newton's law, as long as the resistance that N2x is subjected in the horizontal direction greater than object A2, object will move along the direction of N2x, and is same, as long as the resistance that N2y is subjected to greater than the object in the vertical direction, object will move along the N2y direction.

When the people is sitting on the chair, apply a pressure Nc for the filling bead under the contact-making surface of cushion portion 11, this little club moves down, simultaneously, moving of this bead will cause near bead to move along the direction of Nc1 and Nc2 again, so transmit, and reach stable state up to all positions of filling beads, be cushion top layer filling bead pressure equal and opposite in direction everywhere, this moment, cushion portion 11 was in full accord with the curve of human body.The mechanism of action of rest portions 12 is identical with cushion.Inner little bulb diameter of filling can be arranged between 1mm～10mm, and the bead of this kind size is suitable for the quick dispersion transmission of power.

Charge into compression ratio in the inflation beads of filling in cushion portion 11 and the rest portions 12 and be 3 to 5 times compressed air, the air bearing power of this compression ratio is suitable and the effect of expanding with heat and contract with cold is obvious, when the people was sitting on the chair for a long time, the temperature of cushion portion 11 can raise, bead gas inside expanded by heating, it is fuller that cushion will become, after the people left, after temperature reduced, cushion can recover former state again, even if long-term the use can not caused the cushion gross distortion yet.Axle 14 effects are the angles of regulating between cushion portion 11 and the rest portions 12, by this axle, the angle of cushion portion 11 and rest portions 12 can be spent between 180 degree 90 according to the personal like and regulate arbitrarily, can select 90 degree when for example all serious, 135 degree can be selected when leaning on respite, 180 degree can be selected when lying down rest.

Support portion 13 is used for cushion portion 11 and rest portions 12 are supported to suitable height.In the present embodiment, the groove interface that sets up standard between support portion 13 and the cushion portion 11 fits together by this road groove, and support portion 13 shapes can be made multiple, what stability was best is that four traditional pin support, and the curved surface of can making that comfortableness is best supports so that shake.

The preferred version that the foregoing description is realized for the present invention; and non-limiting exhaustive, the present invention can also have other variations under same idea, need to prove; without departing from the inventive concept of the premise, any conspicuous replacement is all within protection domain of the present invention.
