It is former that the work that the entirety of seat 100 is leaned forward and backrest 10 is laid flat is described in detail with the seat 100 shown in Fig. 2 below
Reason.
Seat 100 is overall to lean forward：As shown in figure 5, when user is normally sitting on seat 100, cam can with latch 23
Not contact.The seat 100 of the present invention can in the past in the middle row seat chair 100 in three rows of seats 100 afterwards, when on back seat 100
Passenger when needing to get on or off the bus, floor latch unlocks the second connecting plate 33, and now user promotes forward backrest 10, with reference to Fig. 6, Fig. 8,
Shown in Figure 10 and Figure 12, the quadric chain that is formed between third connecting rod 53, fourth link 54, the connecting plate 33 of pedestal 20 and second
Rotate forward, rear link (i.e. fourth link 54) and second connecting rod 52, the second side arm the 412, the 4th of the quadric chain connect
The quadric chain formed between bar 54, pedestal 20 and recliner assembly 30 has identical fourth link 54, due to recliner
32 are in lockup state, and recliner assembly 30 and backrest frames 11 are an entirety, and the side arm 412 of third connecting rod 53 and second is forward
Rotate, it is final to drive positioned at front by first connecting rod 51, second connecting rod 52, the first side arm 411, the second side arm 412 and pedestal
The five-bar mechanism formed between 20 rotates forward so that seat 100 is overall to rotate (leaning forward) forward.
Seat 100 is overall lean forward during, the second side arm 412 connected with the pin joint of the first connecting plate 31 second
Side arm 412 and backrest 10 are relatively rotated, and the first side arm 411 and the second side arm 412 are relatively rotated, so present
After the entirety of chair 100 leans forward, the angle of 10 and first side arm of backrest 411 changes, because above-mentioned angle changes, so as to
So that the angle that cushion 40 is rotated down reduces, it can so ensure that the deflection of cushion 40 of seat 100 is relatively small, can make
The distance for sitting basin for obtaining release lever 70 and seat 100 is relatively large.Thus, it is such to be designed to the thickness of seat 100
Compression so that the scope of application of seat 100 of such a structure is wider；Simultaneously as when leaning forward, the angle of the front end of cushion 40 declines not
It is very big, can ensures the release lever 70 of slide rail in the range of suitable comfortableness；Simultaneously for bowl portion, pipe can be used
The section bar additional seat web frame such as material, can reduce the manufacturing cost of seat 100.
Cam unlocking manner：With reference to shown in Fig. 7, Fig. 9 and Figure 11, when the entirety of seat 100 leans forward, cam is pressed downward unlocking
Pin 23, until latch 23 is moved downward to unlocked position, so as to unlock dynamic rail 22, it is overall so to allow for seat 100
Forward slip, increase the space of the 3rd row's passenger getting on/off as much as possible.And the entirety of seat 100 leans forward forward to front position
When, dynamic rail 22 is still in released state.
The process of design use state is returned to for seat 100, it is opposite with above-mentioned link motion process.Pass through backrest 10
Rotate backward driving so that pulls back five connecting rods under two double leval jib collective effects, realizes that seat 100 is overall backward and turn
It is dynamic, until returning to design use state.
The unlocking manner of projective structure 34 of second connecting plate 33：As shown in figure 21 and figure, leaned forward in the entirety of seat 100
When, the mark of motion rail 22 of projective structure 34 is divided into two stages：1st, move forward and up, this process realizes projective structure 34
Motion upwards, process accumulation of energy is pushed in next step to realize, and forward close to the rear portion of release lever 70；2nd, move downward forward,
This process predominantly pushes process, and the gravity of seat 100 directly can be applied to the rear portion of release lever 70 by this process, realizes
Unblock, seat 100 being capable of overall forward slip.
Solve lock set unlocking manner：When seat 100 leans forward, the second connecting plate 33 rotates forward, the phase of the second connecting plate 33
Ground is answered to pull bracing wire 81, bracing wire 81 pulls solution locking plate 83 to be moved to latch 23, latch can be pressed downward so as to solve locking plate 83
23 to unlocked position, and now, the Relative orbit determination 21 of dynamic rail 22 can slide.
It should be noted that the above-mentioned any mode of synchronizing unlocking mode of three kinds of dynamic rails 22 can realize that dynamic rail 22 solves
Lock, when seat 100 is designed production, choose a kind of.
Backrest 10 is laid flat：As shown in Figure 13, Figure 15, Figure 17 and Figure 18, second in floor latch locking recliner assembly 30
Connecting plate 33, four companies formed between second connecting rod 52, the second side arm 412, fourth link 54, pedestal 20 and recliner assembly 30
The second connecting plate 33 in linkage is fixed connecting rod, and recliner 32 switches released state by lockup state, and backrest 10 is around angle modulation
The rotary shaft of device 32 rotates, and second connecting rod 52 rotates forward, and in five-bar mechanism, the connecting rod on the first side arm 411 with
It is described when parallel motion and the second connecting rod on side arm 412 has limited the free degree of second connecting rod 52, it can promote
Five-bar mechanism rotates forward, finally realizes the entire lowering of 100 cushion of seat 40, while backrest 10 rotates be laid flat forward.
Backrest 10 is laid flat the cam unlocking manner of process：With reference to shown in Figure 14, Figure 16 and Figure 19, in initial position, cam
With latch 23 not in contact with now dynamic rail 22 does not unlock, and when backrest 10 rotates 30 ° forward, cam presses to latch 23
Unlocked position, when backrest 10 continues to rotate forward, continue to increase for the volume under pressure of latch 23, until maximum position, so
Cam is rotated further afterwards, and the volume under pressure of latch 23 reduces, until when backrest 10 is turned down to 70 °, now latch 23 is in critical
Released state.Because dynamic rail 22 is in released state during this, when promoting seat 100 backward, seat 100 can be realized to be slided backward
Move until rearmost position；Backrest 10 continues to be laid flat forward, and cam gradually slowly separates with latch 23, until backrest 10 is laid flat,
Both separation, slide rail return to lockup state.
It should be noted that the setting of cam can realize different works when seat 100 leans forward and when backrest 10 is laid flat
With, because the angle that second connecting rod 52 rotates in two operating process is different, second connecting rod during seat 100 leans forward
52 rotate about 80 °, and backrest 10 is laid flat process and rotates about 115 °, and rotational angle difference can realize the shape for pushing slide rail unblock pad
State is different.When seat 100 leans forward, cam can persistently push slide rail；When backrest 10 is laid flat, in pilot process is laid flat
It can realize that slide rail unlocks, seat 100 is overall to be adjusted backward, is realized locking again being laid flat aft ramp, is prevented seat 100 from sliding.
