Leg support skeleton 2 and for adjusting the quadric chain 3 that the posture of leg support skeleton 2 switches between stretching state and retracted state,
Governor motion 1 and quadric chain 3 are set to two groups, are set relative to seat or so mirror image；Governor motion 1 includes installing plate
11, installing plate 11 is provided with and the ratchet 13 being connected is rotated with it by rotating shaft 12, is meshed with ratchet 13 and realizes the ratchet of locking
14 and the spacer pin 19 for realizing unblock, unblock slide plate 10 are engaged with ratchet 13, the unblock slide plate 10 is engaged with ratchet 13
Rotated and be connected with installing plate 11 by rotating shaft, the installing plate 11 that the spacer pin 19 is fixed between unblock slide plate 10 and ratchet 13
On.Two power intakes of quadric chain 3 are fixedly connected with ratchet 13, ratchet 14 respectively, the power output of quadric chain 3
End is fixedly connected with leg support skeleton 2, is additionally provided with to coordinate with ratchet 13, ratchet 14 on installing plate 11 and is realized the return of quadric chain 3
Return mechanism, on installing plate 11 be provided with reinforcement 18.
As shown in Figure 1,3, the return mechanism of the present embodiment includes torsion spring 15, extension spring 16 and the return being engaged with extension spring 16
Spring 17, torsion spring 15 is located in the rotating shaft 12 that is connected with ratchet 14, two resistance ends of torsion spring 15 respectively with quadric chain 3,
Installing plate 11 is fixedly connected, and one end of extension spring 16 is connected with the resistance end of ratchet 14, and its other end is fixedly connected with installing plate 11,
The two ends of return spring 17 are connected with installing plate 11, quadric chain 3 respectively.
As shown in Figure 1, 2, the quadric chain 3 includes being connected with ratchet 14 head rod 31, it is connected with ratchet 13
The second connecting rod 32 and respectively with head rod 31, the second connecting rod 32 rotate be connected the 3rd connecting rod the 33, the 4th company
Extension bar 34, the middle part of the 3rd connecting rod 33 is rotated by rivet 35 with the second connecting rod 32 to be connected, the end of the 3rd connecting rod 33
Rotated and be connected with the 5th connecting rod 37 by bolt 36, the end of the 4th connecting rod 34 is fixedly connected with the 5th connecting rod 37, the
