Background technology
Referring to Fig. 5, present existing Disassembling sofa seat does not have can realize carrying out the motion of each attitude on the basis of placing by wall, be that the Disassembling sofa backrest leans on the wall placement and will put leg when launching forward, the Disassembling sofa backrest only moves forward very little one section, then when backrest when transferring, backrest moves when moving down backward, causes backrest just to contact wall when not being put into the position, make the Disassembling sofa seat can not lean on wall fully, space availability ratio is not high; Existing sliding seat does not have the function that backrest and human body back are synchronized with the movement yet, its back is positioned at sitting posture back K when human body is seated, its head is positioned at sitting posture head L, when human body is lain down, because its seat position is constant, cause its back to be positioned at lying posture back K ', its head is positioned at lying posture head L ', produce a displacement U, make human body uncomfortable.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in prior art, and provide a kind of simple for structure, realize sliding seat zero by wall, realize backrest and seat cushion each attitude of sliding seat all seamless and backrest with the sliding seat backrest hunting gear of back-moving.
the utility model solves the problems of the technologies described above the technical scheme that adopts: this sliding seat backrest hunting gear, it is characterized in that being provided with back rest, backrest the first support member, backrest the first connector, backrest the second support member, backrest the second connector, the backrest guide, back rest is connected by the first rotating shaft with backrest the first support member, back rest is connected by the 7th rotating shaft with the backrest guide, backrest the first support member is connected by the second rotating shaft with backrest the first connector, the backrest guide is connected by the 6th rotating shaft with backrest the first connector, backrest the second support member is connected by the 3rd rotating shaft with backrest the first connector, backrest the second connector is connected by the 5th rotating shaft with the backrest guide, backrest the second support member intersects with backrest the second connector and is connected by the 4th rotating shaft afterwards.
The first rotating shaft described in the utility model, the second rotating shaft, the 6th rotating shaft, the 7th rotating shaft center line separately consists of parallelogram.
A backrest limiting rivet is set on backrest guide described in the utility model, be used for supports and spacing when sliding seat is lain down.
The utility model is simple for structure, and is convenient and practical, realized sliding seat zero by wall, realize backrest and seat cushion each attitude of sliding seat all seamless and backrest with back-moving, make that human body back is imperceptible friction sense, a raising sliding seat comfort level.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
the present embodiment sliding seat backrest hunting gear comprises back rest 1, backrest the first support member 2, backrest the first connector 3, backrest the second support member 4, backrest the second connector 5, backrest guide 6, back rest 1 is connected by the first rotating shaft A with backrest the first support member 2, back rest 1 is connected by the 7th rotating shaft I with backrest guide 6, backrest the first support member 2 is connected by the second rotating shaft B with backrest the first connector 3, backrest guide 6 is connected by the 6th rotating shaft H with backrest the first connector 3, back rest 1, backrest the first support member 2, backrest the first connector 3, backrest guide 6 is by the first rotating shaft A, the second rotating shaft B, the 6th rotating shaft H, the 7th rotating shaft I controls displacement and the pendulum angle of back rest 1, to reach displacement and the lying posture angle that is fit to sliding seat backrest needs, the first rotating shaft A wherein, the second rotating shaft B, the 6th rotating shaft H, the 7th rotating shaft I center line separately consists of parallelogram ABHI(referring to Fig. 1), to reach flexible adjustment and adjustable range is large, backrest the second support member 4 is connected by the 3rd rotating shaft C with backrest the first connector 3, backrest the second connector 5 is connected by the 5th rotating shaft G with backrest guide 6, backrest the second support member 4 intersects with backrest the second connector 5 and is connected by the 4th rotating shaft F afterwards, make displacement that sliding seat forms upon deployment drive backrest the second support member 4 and backrest the second connector 5 and open to control the effect that backrest the first connector 3 and backrest guide 6 open to reach displacement, allow (in figure, the left side the is front) motion forward of backrest bottom when allowing the backrest middle and upper part move down, reach the backrest purpose substantially not mobile with respect to human body back with this.
The utility model also arranges a backrest limiting rivet J on backrest guide 6, be used for support and spacing when sliding seat is lain down, and increases the stability of backrest.
The present embodiment backrest the second support member 4 is connected by the 9th rotating shaft E with the sliding seat drive unit, and backrest the second connector 5 is connected by the 8th rotating shaft D with the sliding seat drive unit, and power and sliding seat drive unit that human body back is driven link.
when being in the sitting posture state at sliding seat, the present embodiment back rest 1 (is in state shown in Figure 2), sliding seat drive unit (this device is prior art) is in rounding state, along with sliding seat is opened gradually, the sliding seat drive unit forms displacement by the 8th rotating shaft D and the 9th rotating shaft E, thus this backrest angle original state of maintenance and with put leg drive unit synchronous shift (namely being in state shown in Figure 3), when continuing motion, sliding seat launches, opening gradually by the 8th rotating shaft D and the 9th rotating shaft E position makes rotating shaft F begin to rotate, drive the 3rd rotating shaft C and rotating shaft G opens, the 6th rotating shaft H and the 4th rotating shaft F Distance Shortened and drive 3 backrest connectors one and rotate immediately, the second rotating shaft B is moving downward because of 3 backrest connectors also, backrest the first support member 2 is moved downward by the second rotating shaft B traction, at the same time because of the motion of the 6th rotating shaft H and the second rotating shaft B, backrest the first connector 3 and backrest the first support member 2, the angle of backrest guide 6 reduces, make the 7th rotating shaft I and the second rotating shaft B distance reduce, above mechanism moves forward backrest, back rest 1 is little because of the displacement that the first rotating shaft A on backrest the first support member 2 turns, on backrest guide 6, the displacement of the 7th rotating shaft I is large, thereby change its angle, make back rest 1 tilt to reach gradually backward lying posture state (being state shown in Figure 4).On rear backrest guide 6, backrest limiting rivet J can pressure-bearing live backrest the first connector 3 when launching fully, increases backrest stability.
The utlity model has and eliminate backrest, realize backrest and seat cushion each attitude of sliding seat all seamless and human body back friction feel and sliding seat during in various attitude backrest can not clip the function of metope, and have simple and durable, the characteristics such as easy to operate, the variation by the sliding seat attitude drives back-rest means for chair.
Every simple deformation of the present utility model or equivalent transformation should be thought to fall into protection domain of the present utility model.
