Embodiment 1
Seeing Fig. 3 to Fig. 7, the leg support of seat system be given in figure, including leg support part 100, take position portion
Divide 200 and leg support part 100 and part 200 of taking position are coated with the surface cover 300 of getting up.
Leg support part 100 includes leg support frame assembly 110 and the lower limb being molded on leg support frame assembly 110
Torr foaming body 120, part of taking position 200 includes taking position frame assembly 210 and being molded over frame assembly of taking position
Medicated cushion foaming body 220 on 210；Surface cover 300 covers at leg support foaming body 120 and medicated cushion foaming body 220
On, wherein the rear end of surface cover 300 and part 200 of taking position are near seatback portion (not shown)
This one end connect.
Leg support frame assembly 110 include one piece of leg support gripper shoe 111, left and right leg support regulating part 112a,
112b and leg support support 113, left and right leg support regulating part 112a, 112b are arranged on leg support gripper shoe 111
Arranged on left and right sides, assembling time, left and right leg support regulating part 112a, 112b are relative to leg support gripper shoe 111
Before and after position can be adjusted, to adapt to the requirement of different leg support length, leg support gripper shoe 111 is used
To support leg support foaming body 120.The front end of leg support support 113 is fixing with leg support gripper shoe 111 to be connected, example
As welding or employing securing member connect.
Frame assembly 210 of taking position includes take position skeleton 211 and left and right downslide guidance tape 212,213, left,
The upside of bottom right chute board 212,213 is respectively fixedly connected with in the arranged on left and right sides of skeleton 211 bottom surface of taking position,
Left and right downslide guidance tape 212,213 is provided with left and right gliding groove 212a, 213a.
Leg support gripper shoe 111 is arranged on by slide track component 410 on a pair takes position on skeleton 211, wherein
Glidepath 411 in upper slide track component 410 is fixed on takes position on skeleton 211, in upper slide track component 410
Upper slide rail 412 and leg support gripper shoe 111 fixing be connected.
The leg support drive mechanism of this embodiment includes motor 510, turbine and worm decelerator 520, screw mandrel
530, nut 540；Turbine and worm decelerator 520 is arranged on the bottom surface of skeleton 211 of taking position, worm gear
The input of worm gear box 520 is connected with the output shaft of motor 510, turbine and worm decelerator 520
Outfan be connected with one end of screw mandrel 530, nut 540 is engaged on screw mandrel 530.Additionally nut 540
Further aspect is connected with surface cover pull bar 610, and fastening is passed through in the most also rear end with leg support support 113
Part connects.
It is left and right that the left and right end of surface cover pull bar 610 is each passed through on left and right downslide guidance tape 212,213
Gliding groove 212a, 213a, such surface cover pull bar 610 both can be supported on left and right downslide guidance tape 212,
On 213, can move back and forth in left and right gliding groove 212a, 213a simultaneously.
The front end of surface cover 300 extands rearward to surface cover pull bar 610 and surface cover after walking around leg support part 100
Pull bar 610 connects.
The feature of the present embodiment is to use in external force in this one end that surface cover 300 is connected with surface cover pull bar 610
The lower elongation of effect and the stretch fabric 310 shortened when external force disappears, so when leg support part 100 is stretched out,
Stretch fabric 310 can be elongated, and when leg support part 100 is retracted, stretch fabric 310 can be shortened.
Certainly surface cover 300 can all use elongation under external force and the bullet shortened when external force disappears
Power cloth or stretch fabric 310 use tension spring component to substitute.
Referring particularly to Fig. 4 A to Fig. 5 B, the operation principle of the present embodiment is as follows:
When needs stretch out leg support part 100, forward starts motor 510, and motor 510 passes through worm and gear
Reducing gear 520 drives screw mandrel 530 to rotate forward, screw mandrel 530 drive nut 540 along screw mandrel 530 to
Moving close to turbine and worm decelerator 520 direction, now nut 540 1 aspect passes through leg support support 113
Promoting whole leg support part 100 to stretch out, such as, stretch out 100mm, nut 540 drives surface cover pull bar simultaneously
610 left and right gliding groove 212a, 213a along left and right downslide guidance tape 212,213 travel forward, and make
The front end of surface cover 300 is also followed leg support part 100 and is travelled forward the elastic force on 50mm, furthermore surface cover 300
Cloth 310 is also extended 50mm by the pulling force of surface cover 300, makes surface cover 300 just meet leg support part 100
The requirement stretched out.
When leg support part 100 regained by needs, reverse starting motor 510, motor 510 passes through worm and gear
Reducing gear 520 drives screw mandrel 530 to rotate backward, screw mandrel 530 drive nut 540 along screw mandrel 530 to
Moving away from turbine and worm decelerator 520 direction, now nut 540 1 aspect passes through leg support support 113
Driving whole leg support part 100 to be retracted into initial position, such as rollback 100mm, nut 540 drives simultaneously
Surface cover pull bar 610 left and right gliding groove 212a, 213a along left and right downslide guidance tape 212,213 to
Rear motion, makes the front end of surface cover 600 also follow leg support part 100 rearward movement 50mm, furthermore surface cover 300
On stretch fabric 310 after the pulling force losing surface cover 300, also shrink 50mm, make surface cover 300 just meet lower limb
The requirement that torr part 100 is return.
Embodiment 2
Seeing the Fig. 8 accompanying drawing with reference to embodiment 1, this embodiment 2 is with the difference of embodiment 1
Leg support drive mechanism is different, and the leg support drive mechanism of this embodiment includes motor 510a and a crank even
Linkage, motor 510a is arranged on the crank 521a on the bottom surface of skeleton 210 of taking position, in toggle
One end be connected with the output shaft of motor 510a, one end hinge of the other end of crank 521a and connecting rod 522a
Connecing, on the one hand the other end of connecting rod 522a is connected with surface cover pull bar 610, the most also with leg support support
The rear end of 113 is connected by securing member.
The remainder of this embodiment is with embodiment 1.
The operation principle of this embodiment is as follows:
When needs stretch out leg support part 100, forward starts motor 510a, motor 510a and drives crank
521a rotates forward an angle, the crank 521a drivening rod 522a motion of rotation, connecting rod 522a
On the one hand promote whole leg support part 100 to stretch out by leg support support 113, such as, stretch out 100mm, simultaneously
Drive surface cover pull bar 610 left and right gliding groove 212a, 213a along left and right downslide guidance tape 212,213
Travel forward, make the front end of surface cover 300 also follow leg support part 100 and travel forward 50mm, furthermore surface cover
Stretch fabric 310 on 300 is also extended 50mm by the pulling force of surface cover 300, makes surface cover 300 just meet lower limb
The requirement that torr part 100 is stretched out.
When leg support part 100 regained by needs, reverse starting motor 510a, motor 510a drive crank
521a rotates backward an angle, counter-rotational crank 521a drivening rod 522a adverse movement, connects
Bar 522a mono-aspect drives whole leg support part 100 to be retracted into initial position, example by leg support support 113
Such as rollback 100mm, drive simultaneously the surface cover pull bar 610 left side along left and right downslide guidance tape 212,213,
Bottom right chute 212a, 213a rearward movement, makes the front end of surface cover 300 also follow leg support part 100 backward
Stretch fabric 310 on motion 50mm, furthermore surface cover 300 also shrinks 50mm after the pulling force losing surface cover 300,
Surface cover 300 is made just to meet the requirement that leg support part 100 is return.
