Description
Technical field
The present invention relates to a kind of experiment seat and control method, this experiment seat is seat surface, the synchronous support human body of chair back energy in change sitting posture, and this control method can make this seat be suitable for different use crowds and different environments for use.
Background technology
There is following two problems in modern handle official bussiness seat:
One:, existing seat have employed the form of the overall chair back mostly, and the inclination angle of this kind of chair back, mostly at 90 degree to 115 degree, is difficult to the waist of human body under forward sitting position state and provides support, the people bent over one's desk working lays boudoir in seat rear, is used for avoiding unsettled the brought muscular fatigue of waist.By shoulder blade and spine-supporting backside pressure during people's trunk bending backwards sitting posture, the radian of back-supported and reclining angle, and what kind of back-supported form is the most rational, industry is but without final conclusion.
Its two: sit people on the seat and constantly adjusting posture, single sitting posture form very easily produces fatigue, is also not suitable for modern life style.Sitting posture form mainly can be divided into forward sitting position, upright sitting posture and layback sitting posture, uses the seat of adjustable inclination backrest can meet different sitting posture demand.The seat of existing backrest adjustable inclination, mainly employs the reclining system of TG/KTG/STG, and the common ground of these systems under reclining state is that backrest is connected by the turning cylinder on chassis with seat.But in use, these inclining mechanisms can not give human body back effective support, usually can produce waist unsettled, the problems such as holding-down.Because such mechanism does not meet ergonomics, under sitting posture state, trunk and thigh bend at pelvis place, under forward sitting position, the acute angle that this bending angle is is summit with hipbone greater trochanter point, when people's trunk bending backwards, bending angle becomes large until obtuse angle gradually, and summit is still at hipbone greater trochanter point.In this series of rotation, the rotating axle center of human body is hipbone greater trochanter point always, and the rotating axle center of seat inclining mechanism but departs from herein.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of seat that people can be made in forward sitting position, upright sitting posture, layback sitting posture form to obtain rationally support, and provides evaluation to be suitable for the size adjustment method of different users and different environments for use.
The present invention is achieved through the following technical solutions.
Experiment seat of the present invention comprises underframe, waist bracket, back bracket, cushion, bustle and back pad.It is characterized in that: cushion is adjustable in the degree of depth and horizontal rotation angle, bustle is adjustable in height, the degree of depth and level (X-axis) anglec of rotation, back pad height, the degree of depth, horizontally rotate in (X-axis) angle and vertical (Z axis) anglec of rotation adjustable, the height of the waist pivot point that waist bracket is connected with underframe is greater than surface height, the line of waist both sides pivot point is arranged in seat surface rear end, and waist pivot point is adjustable at height, depth direction.
On underframe, the adjustment of three nest mechanism can change the height of bustle, the height of waist pivot point and the degree of depth of back pad respectively, nest mechanism is made up of two kinds of steel pipes that caliber size is different, can relative sliding between two steel pipes, bigbore steel pipe there are several locating holes, small-bore steel pipe also there are several locating holes, be installed with alignment pin in locating hole, play regulation stall.
Underframe and cushion rear portion are connected by slidably axle, and between the two with the free degree of relative sliding and rotation, underframe and cushion front contact place are wrapped up by reusable cohesive material, and both can fix or be separated.
Slidably axle between underframe and cushion comprises support and alignment pin, and support is fixed on cushion, and is provided with elongated slot, and alignment pin is fixed on underframe, and its diameter is less than groove width, can in elongated slot relative sliding.
Waist bracket is provided with a pair resilient rotating shaft, and rotating shaft is joint steel pipe respectively, and original state two steel pipe is tightened and at an angle, angularly can be reduced by side's pressure.
Bustle comprises about a pair flat line-locked steel plate, adds the packing ring of different number between steel plate from bustle, can realize bustle level is turned over and under turn over.Back pad comprises about a pair flat line-locked steel plate, and between steel plate from back pad, add the packing ring of different number, can realize back pad level is turned down, vertical varus is turned up.
Underframe is removable, and comprise a pair base and two stulls, base is provided with through hole, and stull end face is provided with screwed hole, both is fixed by screw.The present invention is compared with existing seat, and mainly contain three advantages: the first, lumbar pad is separated with back cushion by the present invention, and the independent lumbar pad rotated ensure that human body waist under various sitting posture state can reasonably be supported.Back cushion and the back cushion that be separated symmetrical by two pieces forms, and two pieces of back cushions form a bending cambered surface, and this cambered surface is consistent with the arc shape of human body back, after guarantee human body by time obtain the support of the best.
The second, for the inclining mechanism of backrest, the present invention proposes a new concept, and the position of inclining mechanism rotating shaft is moved on to the trochiterian outside of Human Physiology rotary part------hipbone on bottom seat surface.By rotating the position of axle, change movement locus during backrest bending.Simultaneously by the angle of inclination of adjustment seat surface, seat is agreed with more to the support energy of human body surface and the spine form of human body and physiological movement characteristic.
3rd, by arranging adjustment hole position, the present invention can regulate the concrete size of seat on sitting face height, the sitting face degree of depth, pivot point height, the pivot point degree of depth, seat surface level angle, bustle vertical angle, back pad level angle and back pad vertical angle, this governor motion expands the scope of application of seat, the Sitting comfort under test analysis different crowd, different operating condition can be used for, for seat design practice provides theoretical foundation as experimental provision.
