The present invention compared with prior art, have simple and durable, characteristics such as easy to operate, change caused motion by attitude and drive the something or somebody to fall back on device linkedly by sliding seat, both simplify the position adjustments of something or somebody to fall back on device, and can guarantee the support of the power that all head provided in each position of sliding seat again.
Description of drawings:
Fig. 1 is the side view that the preferred embodiment of the present invention reaches relevant attachment;
Fig. 2 is the side view that the preferred embodiment of the present invention is in primary importance, and wherein the something or somebody to fall back on installation portion is in the punctured position of approximate horizontal;
Fig. 3 is the side view that the preferred embodiment of the present invention is in the second place;
Fig. 4 is the side view that the preferred embodiment of the present invention is in the 3rd position, and wherein the something or somebody to fall back on installation portion is in roughly parallel with backrest body side frame expanded position.
The specific embodiment:
Referring to Fig. 1～Fig. 4, embodiment of the invention headrest device of movable seat comprises something or somebody to fall back on upper connecting rod 4, something or somebody to fall back on driving arm 5, the first something or somebody to fall back on support 6, the second something or somebody to fall back on support 7, something or somebody to fall back on installing plate 8, upper connector 9, backrest fastening member 10, following connector 11.Wherein, an end and the something or somebody to fall back on lower link 3 of something or somebody to fall back on upper connecting rod 4 are fixed together, thereby the motion of mechanical extending apparatus is delivered on the something or somebody to fall back on.Something or somebody to fall back on upper connecting rod 4 other ends and something or somebody to fall back on driving arm 5 are riveted together and form the tenth turning cylinder J.Something or somebody to fall back on driving arm 5, the first something or somebody to fall back on support 6, upper connector 9 is riveted together and forms the 5th turning cylinder E, something or somebody to fall back on driving arm 5, the second something or somebody to fall back on support 7, upper connector 9 is riveted together and forms the 4th turning cylinder D, something or somebody to fall back on support 6, something or somebody to fall back on installing plate 8 is riveted together and forms the 7th turning cylinder G, the second something or somebody to fall back on support 7, something or somebody to fall back on installing plate 8 is riveted together and forms the 6th turning cylinder F, upper connector 9, backrest fastening member 10 is riveted together and forms the 8th turning cylinder H, backrest fastening member 10, following connector 11 is riveted together and forms the 9th turning cylinder I, the first something or somebody to fall back on support 6, following connector 11 is riveted together and forms the 3rd turning cylinder C.Backrest fastening member 10 is fixed on the backrest frame 14.
When something or somebody to fall back on installing plate 8 is in appearance at sliding seat (being in primary importance shown in Figure 2), drives extending apparatus (this device is a prior art) and be in the curling position.Along with opening gradually of sliding seat, drive extending apparatus work and the integrated leg device of putting is wherein forwards launched, the first rotating shaft A that movable connector 17 drives on the base side attachments 2 moves to the back upper place.Backrest connecting rod 12 rear ends rotate counterclockwise around the second rotating shaft B simultaneously, and backrest connecting rod 12 front ends rotate counterclockwise around the 11 turning cylinder K.On the other hand, movable rotating backward of connector 17 is delivered to base side attachment 2 through base side attachment 1, in conjunction with the travelling forward of backrest connecting rod 12, the second rotating shaft B is moved upward again, so promote something or somebody to fall back on lower connecting rod 3, something or somebody to fall back on upper connecting rod 4 moves upward.Under the upwards promotion of something or somebody to fall back on lower connecting rod 3, something or somebody to fall back on upper connecting rod 4, something or somebody to fall back on driving arm 5 rotates counterclockwise along the tenth turning cylinder J, thereby drive upper connector 9,10 rotations of backrest fastening member, and drive something or somebody to fall back on support 6, something or somebody to fall back on support 7 upwards promotes, because the speed that the 6th turning cylinder F promotes greater than the 7th turning cylinder G, therefore causes something or somebody to fall back on installing plate 8 to turn forward gradually and reaches the second place shown in Figure 3.Compare with primary importance shown in Figure 2 this moment, and base seat frame 15 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, if base seat frame 15 further moves forward greatly, and the bottom and the backrest connecting rod 12 that drive back frame 14 further move forward, and back frame 14 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 of back frame 14 and base connecting rod 3, following something or somebody to fall back on connecting rod 4, go up that something or somebody to fall back on connecting rod 5 also tilts and and the continuation that moves 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.For the equivalent transformation of inventive embodiments 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.
