The specific embodiment:

Referring to Fig. 1～Fig. 4, the sliding seat of the embodiment of the invention comprises:

Backrest module, this backrest module comprisesback frame 8, medial side attachment 9,backrest fastening member 10,backrest connecting rod 11, medial side attachment 9,backrest fastening member 10 all are fixed on theback frame 8,backrest connecting rod 11 front ends and medial side attachment 9 are articulated in the 4th rotating shaft D, and backrest module is a prior art.

Base assembly, this base assembly comprisesbase seat frame 13 and drives extending apparatus, described base assembly and described backrest module are hinged, described driving extending apparatus comprisesmovable connector 1,base side attachment 2, base connecting rod 3 and the integrated leg device of putting,movable connector 1 is fixedlyed connected withbase side attachment 2, base connecting rod 3 links at the first rotating shaft A withbase side attachment 2,movable connector 1 links with the integrated leg device 15 of putting that is installed in the preceding bottom of base, drive extending apparatus and drive backrest module, the base assembly motion, the wherein integrated leg device 15 of putting is prior art.

Something or somebody to fall back on device, this something or somebody to fall back on device comprise following something or somebody to fall back on connectingrod 4, go up something or somebody to fall back on connectingrod 5, something or somebody to fall back onfixture 6, something or somebody to fall back onkeeper 7 and something or somebody to fall back on installingplate 14; Wherein, one end of following something or somebody to fall back on connectingrod 4 is installed on theback frame 8, the other end of following something or somebody to fall back on connectingrod 4 andbackrest connecting rod 11 rear ends, base connecting rod 3 link in the second rotating shaft B, following something or somebody to fall back on connectingrod 4 flexibly connects by bolt with last something or somebody to fall back on connectingrod 5, form the 3rd rotating shaft C, can rotate withback frame 8 motions.Something or somebody to fall back onfixture 6 lower ends are fixed together by bolt and last something or somebody to fall back on connectingrod 5, and something or somebody to fall back onfixture 6 other ends and something or somebody to fall back on installingplate 14 weld together.Something or somebody to fall back onkeeper 7 is installed on theback frame 8, and something or somebody to fall back onfixture 6 parts are enclosed within 7 li of something or somebody to fall back on keepers, can slide in something or somebody to fall back onkeeper 7.

When something or somebody to fall back onfixture 6 is in appearance at sliding seat (being in primary importance shown in Figure 2), this position base assembly, something or somebody to fall back on device (comprising something or somebody to fall back on fixture 6) are in the curling position.Along with opening gradually of sliding seat,base seat frame 13 forwards moves, drive extending apparatus work simultaneously and the integrated leg device of putting is wherein forwards launched, the first rotating shaft A thatmovable connector 1 drives on thebase side attachment 2 moves to the back upper place with respect to base seat frame 13.The bottom that drives backframe 8 that moves forward ofbase seat frame 13 also moves forward, and then drivebackrest connecting rods 11 by the medial side attachment that is connected with back frame 89 and travel forward,backrest connecting rod 11 rear ends rotate counterclockwise around the second rotating shaft B simultaneously, andbackrest connecting rod 11 front ends rotate counterclockwise around the 4th rotating shaft D.On the other hand, movable rotating backward ofconnector 1 is delivered to base connecting rod 3 throughbase side attachment 2, in conjunction with the travelling forward ofbackrest connecting rod 11, the second rotating shaft B is moved upward again, and then promote down something or somebody to fall back on connectingrod 4, go up something or somebody to fall back on connectingrod 5 and move upward.Following something or somebody to fall back on connectingrod 4, under upwards the promoting of something or somebody to fall back on connectingrod 5, move on to behind something or somebody to fall back onfixture 6 lower ends and reach the second place shown in Figure 3.Compare with primary importance shown in Figure 2 this moment, andbase seat frame 13 stretches out slightly forward, puts leg and opens, and backrest recedes slightly, and something or somebody to fall back on erects linkedly, is suitable for seated person and leans against and see TV on the seat, thereby also can be called the TV position.During the TV position, ifbase seat frame 13 further moves forward greatly, and the bottom and thebackrest connecting rod 11 that drive backframe 8 further move forward, and backframe 8 tilts greatly simultaneously.At this moment,movable connector 1 further rotates backward and translation by its predetermined path of movement, and impels base connecting rod 3 still to move upward.Under the synergy that moves upward of the inclination ofback frame 8 and base connecting rod 3, following something or somebody to fall back on connectingrod 4, last something or somebody to fall back on connectingrod 5 also tilt and move upward, make sliding seat be in the 3rd position shown in Figure 4, seated person almost can be sitting on the seat with lying posture, but the something or somebody to fall back on device ejects the extreme higher position linkedly.In whole motion process, with the motion of sliding seat, the something or somebody to fall back on device can provide good supporting to head all the time.

The present invention is not limited to above preferred embodiment, and can adopt other any mechanism and the simple deformation of the above-mentioned position linkage that can realize something or somebody to fall back on and sliding seat, as long as can realize above-mentioned linkage function.In the present invention, hinged bolt, pin or the rivet of adopting between above-mentioned each parts realized.The arc design of something or somebody to fall back onfixture 6, something or somebody to fall back onkeeper 7 has guaranteed the attractive in appearance of sofa outward appearance.For the equivalent transformation of sliding seat width and type of drive, and the equivalent transformation of run-on point connected mode all belongs to the scope of protection of the invention.
