On bar 222, and the rope body 552 is set on reel 551 and tool can fold elasticity, the support of rope body 552 one end and foot pad unit 4
It is combined in front of portion 42, and foot pad unit 4 is provided and folds elasticity.
Electric rod 6, which has motor 61, can drive 6 expanding-contracting action of electric rod, behind 6 one end of electric rod and 2 sitting frame 21 of seat unit
The 6th articulated section 213 of Fang Zhongyang is pivotally connected, and the other end is pivotally connected with the 22nd articulated section 535 for making 53 central front of motion block, and
Keep foot pad unit 4 undeployed and the electric rod 6 stretches a segment length state when 2 rear of seat unit is not improved.
The electric rod when present invention enables chair back unit 3 not swing back, foot pad unit 4 is un-extended, 2 rear of seat unit is not improved
6 can set spread length to position and make 53 angle of motion block and ensure that foot pad unit 4 will not stretch and 2 rear of seat unit will not mention
Height, but the telescopic rod 54 has extension elongation at this time, and the rope body 552 of the rope hauling device 55 can draw the support portion of foot pad unit 4
42 is equivalent to have preferably equivalent stability.
Referring to Fig. 5, the present invention, which enables electric rod 6 that can drive when extending, makees 53 top biased forwards of motion block drive telescopic rod 54
Forward and foot pad unit 4 are unfolded, and the backrest 31 of chair back unit 3 can be deviated slightly backward at this time, and the abutment end at 4 rear of foot pad unit
415 with the stop section 214 of seat unit 2 against the maximum expanded angle of foot pad unit 4 can be limited, and can provide the exhibition of foot pad unit 4
The backrest 31 of chair back unit 3 will not substantially swing back in order to which occupant reads or make other work when opening.
Referring to Fig. 6, the present invention enables electric rod 6, persistently elongation can enable and make 53 rear of motion block and offset up and drive the chair back
The first connecting rod 32 of unit 3 deviates and 31 backward wing of backrest, and this is made 53 front side top of motion block and can deviate simultaneously towards front
And compressible telescopic rod 54, thus the telescopic rod 54 can provide and make the sustainable actuating length of motion block 53 and make backrest 31 that can normally swing back
Movement do not influence foot pad unit 4, and make chair back unit 3 movement can be detached from foot pad unit 4, the backrest 31 swing back larger angle when can
Occupant's relatively approach lying position is provided to have preferable lying or leaning comfort, and arc-shaped slot when aforementioned 31 backward wing of backrest
313 convex buttons 215 that can correspond to seat unit 2 are acted to have preferable action stability, and the arc-shaped slot 313 can limit backrest 31
Maximum reclined by angle.
Referring to Fig. 4, the present invention enables electric rod 6 that can enable when shortening again makees 53 reserve migration of motion block, and chair back list can be driven
The backrest 31 of member 3 folds and foot pad unit 4 folds, and the rope body 552 of the rope hauling device 55 can draw foot pad list by appropriate pulling force
Member 4 folds stability to be promoted.
Fig. 7,8 are please referred to, electric rod 6 can be enabled to shorten again when the present invention stands up to act, and can drive and make the offset of motion block 53 simultaneously
Make that movement can be raised before the first and second frame body 51,52, but the first and second frame body 51,52 can interlock seat unit 2 it is corresponding raise and
Rear raises up movement, and can provide that occupant's buttock can be improved and center of gravity is convenient for standing up to act forward.
Therefore the present invention need only use an electric rod 6 can make foot pad unit 4 fold or be unfolded, 31 hypsokinesis of backrest
Angle adjustment, 2 raising of seat unit movement, black box of the present invention, which is simplified and can be had, preferably makees dynamic stability, and the present invention can
Foot pad unit 4 and 31 separating action of backrest is enabled to promote read or lie low rest more preferably convenience and comfort effect, and aforementioned reality
It applies example to illustrate for the present invention, and non-present invention limits, equivalent change also should belong to the present invention for it for all institutes of spirit according to the present invention
