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～Fig. 8, the utility model embodiment comprises backrest module 1, seat frame assembly 2, bracket component 3, wrench assembly, controlled air spring 8, base assembly, handrail 9.Base assembly comprises the axis of cone 4 and base 5.Wrench assembly comprises spanner 6 and drag-line 7.Seat frame assembly 2 comprises a frame body 21, seat frame base 23, the assembly 22 that is in transmission connection, leg extension assembly 24.Leg extension assembly 24 comprises stretching, extension body 243, extension link 241, positioning linkage rod 242.
Controlled air spring 8 one ends are connected with seat frame body 21, and the other end is connected with backrest module 1, that is to say, controlled air spring 8 one ends are connected with seat frame assembly 2, and the other end is connected with backrest module 1.
Drag-line 7 one ends are connected with spanner 6, and the other end is connected with the control end of controlled air spring 8, that is to say, wrench assembly is connected with controlled air spring 8.Spanner 6 is fixed on the handrail 9, and handrail 9 is fixed on the bracket component 3.
Bracket component 3 is fixing with seat frame base 23 by screw, makes bracket component 3 fixing with seat frame assembly 2.
Taper hole closely is connected on the axis of cone 4 upper ends awls post and the seat frame base 23, makes it closely be connected with a frame assembly 2; Awl post in lower end closely is connected with taper hole on the base 5, and the axis of cone 4 upper ends awl post and lower end are bored post and can be realized relatively rotating.
The assembly 22 that is rotationally connected is rotationally connected with seat frame base 23 by revolute pair b.
The assembly 22 that is in transmission connection is rotationally connected by revolute pair t and backrest module 1, makes backrest module 1 and seat frame assembly 2 be rotationally connected.
As shown in Figure 3, when the user is seated on the frame, backrest is close at the back, both hands place on the both sides handrail 9, when both hands are given 9 one power F that push away forward of handrail, handrail 9 can give reciprocal reaction force F1 to the people simultaneously, this moment is because the people is close to backrest, reaction force F1 is equivalent to act on the backrest module 1, because backrest module 1 links to each other by controlled air spring 8 with seat frame assembly 2, because this moment, controlled air spring 8 was in locking-in state, stroke does not change, and just backrest module 1 remains unchanged with seat frame body 21 relative positions, because revolute pair a, the effect of b and t, make seat frame body 21 rotate around revolute pair b with backrest module 1 integral body, promptly transmission connection piece assembly 22 turns clockwise around revolute pair b, and direction is shown in the A among Fig. 4.
Because seat frame base 23 is in relative static conditions, and displacement backward takes place with respect to seat frame base 23 21 this moments in seat frame body relatively, direction is shown in the B among Fig. 4, because extension link 241 is rotationally connected by revolute pair c, d respectively with seat frame body 21 and seat frame base 23, at this moment, extension link 241 turns clockwise around revolute pair c, thereby make extension link 241 obtain driving force F2, positioning linkage rod 242 1 ends and seat frame body 21 are rotationally connected by revolute pair e, because the effect of driving force F2, positioning linkage rod 242 turns clockwise around revolute pair e.
At this moment, because the inner link of leg extension assembly 24 all is to be rotationally connected by revolute pair, leg extension assembly 24 begins to stretch.Along with the expansion of leg extension assembly 24, when positioning linkage rod 242 rotates to when contacting with limited post f around revolute pair e, because the effect of limited post f, leg extension assembly 24 reaches the maximum position place, as shown in Figure 7.This moment, whole brandreth was in state as shown in Figure 6.Limited post f is on the fixing present frame body 21.
As shown in Figure 6, give 6 one power F3(of spanner this moment is that the people spurs spanner 6) since the effect of drag-line 7, controlled air spring 8 releases, on backrest module 1, apply a power F4(this moment and be generally the deadweight of user back), because controlled air spring 8 is in released state, under the pressurized situation, stroke shrinks, backrest module 1 is rotated around revolute pair t, when controlled air spring 8 was compressed to minimum position, backrest module 1 reached maximum extension position, promptly as shown in Figure 8.
The comfort level provide brandreth to use is provided, backrest module 1 comprises two parts, i.e. active head restraint 11 and backrest body 12, and active head restraint 11 rotates stressed joints by limit hinge y with backrest body 12, and the backrest body 12 and the assembly 22 that is in transmission connection are rotationally connected.When the user give 11 1 power F5(users of active head restraint in use backhand pull headrest) time, active head restraint 11 rotates around y, thereby reaches the adjustment headrest positions, makes the user obtain more comfortable position.
