The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment: referring to Fig. 1～Figure 14, backrest module 1 is rotationally connected with seat frame assembly 3 by two rotating shaft B.Seat frame assembly 3 is rotatably connected on the armrest support 12.
The stiff end of controlled air spring 2 is rotatably connected on the backrest module 1, and simultaneously, the movable end of controlled air spring 2 is rotationally connected on the present frame assembly 3.
Wrench assembly 5 comprises spanner 51, spanner fixed mount 52 and cable wire.On one side of the fixing present frame assemblies 3 of spanner fixed mount 52 (about all can), spanner 51 be rotatably connected on the spanner fixed mount 52.One end of spring is fixed on the spanner 51, and the other end is fixed on the spanner fixed mount 52, and spring plays the effect that resets to spanner 51.Cable wire one end is fixed on the spanner 51, and the other end is fixed in the movable end place of controlled air spring 2.Tension by spanner 51 and unclamping drives cable wire and moves, and realizes release and locking to controlled air spring 2.
Interlock headrest 7 is rotatably connected on the backrest module 1 by turning joint t.Turning joint t comprises hinge connecting sheet t1, latch t2, rivet t3, pad t4.Hinge connecting sheet t1 is two, and two hinge connecting sheet t1 are rotationally connected by rivet t3.Wherein a slice hinge connecting sheet t1 and backrest module 1 are fixing, are fixed with latch t2 on this hinge connecting sheet t1; Another sheet hinge connecting sheet t1 is fixing with interlock headrest 7, and this hinge connecting sheet t1 is provided with confined planes t5.That is to say that interlock headrest 7 can rotate with respect to backrest module 1.When hinge connecting sheet t1 forwarded extreme position to clockwise or counterclockwise, confined planes t5 blocked latch t2, made it continue to turn in the same direction again.The maximum rotation angle of turning joint t can be regulated by the width D of latch t2 and confined planes t5 height H and hinge connecting sheet t1.Such turning joint t is two.
Backrest module 1 includes backrest brace 11 fixed thereon, and seat frame assembly 3 includes seat frame brace 31 fixed thereon.Have chute 91 on the interlock slide plate 9, interlock slide plate 9 one ends and backrest brace 11 are rotationally connected, the other end is slidingly connected with seat frame brace 31 by the screw of chute 91 and seat frame brace 31, when backrest module 1 changed with an angle of frame assembly 3, the screw of seat frame brace 31 terminations can be realized sliding in chute 91.
Gangbar 8 one ends are rotatably connected on the interlock headrest 7, and the other end is rotatably connected on the centre position of interlock slide plate 9.
When present embodiment was in rounding state, controlled air spring 2 was in the full extension state, and spanner 51 is in releasing orientation simultaneously, guarantees that controlled air spring 2 is locked in the full extension state all the time.When straining spanner 51 at once, by the connection of cable wire, controlled air spring 2 is in released state, at this moment, on backrest module 1, apply one generally, rely on user back strength as the power F1(of Fig. 2 direction), controlled air spring 2 is subjected to force compresses, backrest module 1 is rotated around rotating shaft B, realize the stretching, extension of backrest module 1, when controlled air spring 2 is in complete rounding state, unclamp spanner 51, lock controlled air spring 2, this moment, present embodiment just was in the full extension state.
In stretching process, armrest support 12 is fixing all the time, and seat frame assembly 3 relative to armrest support 12 skew takes place and rotates, and leg rest is stretched assembly 19 produce a stretching force, makes leg rest stretch assembly 19 and stretches.
When present embodiment is in rounding state, backrest module 1 is in initial position with seat frame assembly 3, and the screw of seat frame brace 31 1 ends is positioned at the low order end of interlock slide plate 9 chutes 91, because the connection of gangbar 8, interlock headrest 7 is in same position (being initial position) with backrest module 1.When controlled air spring 2 is subjected to force compresses, backrest module 1 is with respect to seat frame assembly 3 angles change (being that backrest module 1 is toppled over backward), this moment, the screw of seat frame brace 31 1 ends slided in chute 91, because the pulling of gangbar 8, interlock headrest 7 relatively rotates by turning joint t and backrest module 1, when backrest module 1 is stretched over maximum position, screw slippage on the seat frame brace 31 is to the high order end of chute 91, and interlock this moment headrest 7 relative backrest module 1 link to maximum angle.
Present embodiment from complete rounding state to complete deployed condition process, strain spanner 51 all the time, when unclamping spanner 51, controlled air spring 2 locking positions, thus realized any control to the present embodiment angle.
When present embodiment is in extended configuration, promptly strain spanner 51, at this moment, controlled air spring 2 is in released state, and controlled air spring 2 relies on the pressure of internal gas to reset rapidly, thereby backrest module 1 is rotated around rotating shaft B, be in the full extension state up to controlled air spring 2, remove to unclamp spanner 51, lock controlled air spring 2, present embodiment is in complete rounding state.
The utility model is realized manual operation by wrench assembly 5 and controlled air spring 2.When back push-rod electric machine 10 and leg rest push-rod electric machine 11 are installed in the utility model, just can realize electric functions, by hand controller, can control motor range, thereby reach the flexible function of stretching in back with leg rest.Back push-rod electric machine 10 is connected on the backrest module 1, and its push rod is connected with seat frame assembly 3.Leg rest push-rod electric machine 11 connects on the present frame assembly 3, and its push rod is connected with armrest support 12.
The utility model can also cooperate band to change the chassis and use by simple repacking, realizes the band rotating function.Band changes the chassis and has following two kinds of structures:
As Fig. 7 is a kind of structure.At armrest support 12 bottoms welding a connecting piece 13, be welded to connect with axle 14 then, axle sleeve 15 is placed in the axis hole on chassis 16, be taper fit, axle 14 is enclosed within the plastic bushings in the axle sleeve 15, and therefore axle 14 can be realized rotation axle sleeve 15 in, thus the feasible band rotating function that the utlity model has.
As 8 figure is another kind of structure.Brace 13 and armrest support 12 welding weld an axle sleeve 17 then on brace 13, circle has the tapering and the axis of cone 18 to match in this axle sleeve 17, and the axis of cone 8 bottoms can match with chassis 16 axis holes.The axis of cone 18 itself is with and is changeed, upper end connecting bushing 17, and the lower end connects chassis 16, thus the feasible band rotating function that the utlity model has.
The utility model can also be by to the widening of armrest support 12, thereby realize deriving of products such as 2 people positions, 3 people positions, makes the utility model form seriation, meets the demand of market diversification.
As Fig. 9, the utility model 2 people positions are that 2 people position armrest supports are joined in 21 people positions
As Figure 10, the utility model 3 people positions are that 3 people position armrest supports are joined in 31 people positions.
The utility model is by widening backrest module 1, seat frame assembly 3 and armrest support 12, other structural principles are constant, can also realize 1.5 people positions (as Figure 11), and on this basis, according to many people position implementation, can also realize 2.5 people positions (as Figure 12).
