Screwed part or main shaft 260 are coupled to drive shaft 254, and cross over sizable part of main shaft guide rail 192.It is main Axis 260 has nearside and distal thread end 264,268.As shown, proximal thread is right-hand thread, and distal thread is left Hand screw thread, but chirality can be reversed in alternative embodiments.Proximal thread end 264 is rotationally fixed to and is received in In the opening 272 limited in the end of drive shaft 254, so that main shaft 260 is revolved with drive shaft 254 when motor 234 activates Turn.Traveling member or sliding block (i.e. nearside sliding block 280 and distal side sliding block 284) are fixed around each end of thread 264,268 of main shaft 260 Position.Each sliding block 280,284 includes the internal screw thread ontology for engaging with main shaft 260；Be formed as main shaft guide rail 192 A part the matched opposed groove 290,292,294,296 of opposed edge 300,304.In main shaft rotation, opposite spiral shell Line spindle end 264,268 causes sliding block together with groove/edge interface of the sliding block 280,284 with main shaft guide rail 192 280,284 along main shaft 260 opposite translational motion.It is sliding that the buffer 308 being positioned adjacently with drive shaft 254 provides nearside The limit of one end of the traveling of block 280.Second buffer 312 adjacent with the stop part 316 of centrally-located establishes the second traveling The limit, and limit the moving range of nearside sliding block 280.

Nearside and distal side flexible cable 320,324 are coupled to nearside sliding block 280 and distal side sliding block 284 respectively.Each Drag-line 320,324 includes first end 330, second end 334 and drag-line ontology 338.First end 330, which has, is assemblied in each sliding block 280, the connector 344 in 284 ontology to move.The drag-line ontology 338 of each drag-line 320,324 is from first end 330 extend, and drag-line ontology 338 limits interlude 350, and a part of interlude 350 is corresponding logical generally within each In road 180.Interlude 350, which terminates at, to be coupled to volume end accessory 354 (for example, drag-line 324) or is alternatively coupled to At the second end 334 of hook accessory 356 (for example, drag-line 320).Volume end accessory 354 is adapted to engage with such as torsionspring of spring 362 First end 358.Although be shown as it is associated with distal end portion 124, spring 362 can using distally and proximally drag-line 320, One or both operation in 324 corresponding second end 334.Spring 362 includes second end 366, and second end 366 is configured to It is attached to the hook end 370 of hinge 374, and when tenant sits down first and in operation during enhancing tenant's comfort level Allow the limited deflection of lumbar support system 100.The hook accessory 356 of drag-line 320 winds the hook end of opposite hinge 374 370 a part.

Hinge 374 is formed hinge of " living ", in the side opposite with hook end 370, upper and lower part 130,134 this two At person, the adjacent basket 110 of " work " hinge.As shown, hinge 374 include the first, second, and third pivotal point 380,384, 388, but be also in this range fewer of more than three pivotal points.As shown in Fig. 2,4 and 5, pivoting point 380, 384, interference of the prevention to motor 234 during the process of 388 travelings for being positioned at basket 110.Hinge 374 and basket 110 are preferred Ground is formed as one part.Alternatively, hinge 374 can be fastened to basket 110 in the manner known to persons skilled in the art Separate piece.The hook end 370 of hinge 374 is formed to be assemblied on coupling element, the coupling element in the form of being attached silk 390, The attachment silk 390 is fixed to the corresponding vertical support member 34,38 of frame 26 (see Fig. 1).

In operation, using the electric activation switches preferably with 14 adjacent positioned of backrest 18 or seat bottom, seat is accounted for According to person's actuation power actuator 230.With reference to Figure 4 and 5, when actuator 230 is activated, lumbar support system can contract completely Return is set in any position between (Fig. 4) and fully extended position (Fig. 5).When being powered to motor 234, worm gear 246 is connect Conjunction rotates drive shaft 254, to rotate main shaft 260 simultaneously.If lumbar support system 100 is started to retract basket 110, Main shaft 260 rotates in a first direction.If lumbar support system 100 is started to extend basket 110, main shaft 260 is opposite Second direction on rotate.Starting in either direction is that user can be selected using electric activation switches.Due to sliding block 280, the interaction at the edge 300,304 of 284 groove 290,292,294,296 and main shaft guide rail 192, the rotation of main shaft 260 Turn to translate sliding block 280,284, one in sliding block 280,284 advances on proximal direction (120), and sliding block 280,284 In another advance on distal direction (124).

If tenant it is expected to extend basket 110 to provide more lumbar supports, the rotating clockwise of main shaft 260 (from Distal direction 124 is observed) cause that nearside sliding block 280 is distally advanced along main shaft 260 and distal side sliding block 284 is along main shaft 260 advance to nearside, i.e. sliding block 280,284 and their respective attachment drag-line 320,324 is closer to each other.With sliding block 280, 284 assemble, and a part of the interlude 350 of each drag-line is slided in their respective channel 180, to contact basket 110. As in Fig. 4 as shown in arrow 392, this contact produces the power against basket 110 for guiding basket forward.When nearside sliding block 280 When contacting buffer 312, motor 234 stops, this stops the rotation of main shaft 260.Well known to a person skilled in the art at certain The other methods powered off at a progress point to motor 234 also can be used in being used together with lumbar support system 100.

The hinge 374 that attachment silk 390 is anchored at hook end 370 promotes the movement of basket 110 by flexure, is advanced with running through Smooth movement is provided to range.As shown in FIG. 5, pivoting point 380,384,388 allow when fully extended hinge 374 around Motor 234 falls down.Each is secured to the attachment silk 390 of the corresponding vertical supporting element 30,34 of frame 26 if necessary It is rotated with the movement of lumbar support system 100.

If tenant it is expected that basket 110 is retracted to reduce lumbar support amount, the rotation counterclockwise of main shaft 260 causes nearside Sliding block 280 is advanced along main shaft 260 to nearside and distal side sliding block 284 is distally advanced along main shaft 260, i.e., sliding block 280, 284 and they respective attachment drag-line 320,324 separate.As sliding block 280,284 moves away from out, from the interlude of drag-line 350 mitigate against the pressure of basket 110, and as shown in arrow 394, basket 110 retracts backward in response in Fig. 5.Work as cunning When block 280 contacts buffer 308, motor 234 stops as previously described.

During the process that basket 110 is advanced, extends from being retracted into and retracted from extending to, the holding of drag-line 320,324 is set It sets in essentially identical plane, and the angle [alpha] between the first end 330 and second end 334 of each drag-line 320,324 (see Fig. 4) keeps obtuse angle.

Fig. 6 shows the alternative version of the lumbar support system 400 for seat 410, is preceding describing its totality Feature.Seat 410 includes seat bottom 414 (shown in dotted line), foldable seat backrest 418 and has vertical support member 434,438 frame 426.In profile pad or flexure pad 440 in the form of lumbar support member include laterally outside silk 444, in Centre silk 448 and the multiple transverse wires 452 extended between laterally outside silk 444.Frame 426 can further comprise a pair of of reception Device 456, the pair of receiver 456 are used to receive the supporting element of head rest (not shown).As shown, lumbar support system 400 The lumbar support mechanism 500,502 being independently adjusted including a pair.

Fig. 7 shows lumbar support system 400, Fig. 8 be shown specifically referred to relative to proximal end 520 and distal end portion 524 it is close The component of lumbar support mechanism 500 is adjusted in side.

Driving assembly or actuator 530 are such as wrapped in the preceding System describe about Fig. 1 substantially as shown in figure 3 a It includes: the motor 534 of interaction；Motor drive shaft with pinion gear 538；Shell 542；Worm gear 546；Cap 550 and drive shaft 554. Screwed part or main shaft 560 are coupled to drive shaft 554, and cross over sizable part of main shaft guide rail 562.Main shaft 560 has There are right hand proximal thread and left hand distal thread.Proximal thread end 564 is rotationally fixed to and receives by drive shaft 554 In the opening 572 that end limits, and in the actuating of motor 534, proximal thread end 564 is rotated with drive shaft 554.Sliding block (i.e. nearside sliding block 580 and distal side sliding block 584) is positioned rotating around each end of thread 564,568 of main shaft 560, each sliding block With the internal screw thread ontology for being engaged with main shaft 560.Opposed groove 590,592,594,596 be formed as main shaft guide rail 562 A part opposed edge 600,604 match, to cause the opposite translational motion of sliding block 580,584 during operation.With Buffer 608 that drive shaft 554 is positioned adjacently provides the first travel limit of nearside sliding block 580, and with centrally-located The second adjacent buffer 612 of stop part 616 provides the second travel limit, these limit limit the mobile model of nearside sliding block 580 It encloses.

Nearside and distal side drag-line 620,624 are coupled to nearside sliding block 580 and distal side sliding block 584 respectively.Each drag-line 620,624 include first end 630, second end 634 and drag-line ontology 638.The first end 630 of each drag-line 620,624 includes It is coupled to connector 644 of the ontology of corresponding sliding block 580,584 to move with it.The drag-line of each drag-line 620,624 Ontology extends from first end 630, and drag-line ontology limits interlude 650.As shown in FIG. 8, nearside lumbar support mechanism The interlude 650 of 500 distal side drag-line 624 is longer than the interlude 650 of the nearside drag-line 620 of same lumbar support mechanism.Drag-line 624 this longer interlude 650 is located in rigid sleeve 652, which has bigger than the diameter of drag-line 624 Internal diameter, to allow the moving freely in rigid sleeve 652 of drag-line 624.Nearside and distal side drag-line 620,624 are in each Between a part of section 650 pass through clip 660 and by the clip 660 include, clip 660 is by outer filaments 444 by nearside and distal side Drag-line 620,624 and thus by lumbar support mechanism 500 be connected to flexure pad 440.Each interlude 650 terminates at second end At 634, second end 634 is coupled to hook accessory 668, and hook accessory 668 itself is fixed to the corresponding vertical support portion of frame 426 Part 434,438.With reference to Fig. 7, distal side lumbar support mechanism 502 is the mirror image of nearside lumbar support mechanism 500.

Seat occupant can optionally select to activate nearside lumbar support mechanism 500 or distal side waist in an identical manner Supporting mechanism 502.Alternatively, seat occupant can using identical actuation of the switch nearside and distal side mechanism 500, Both 502.Operation description below will focus on supporting mechanism 500, but be equally applicable to supporting mechanism 502.

Using the electric activation switches preferably with 414 adjacent positioned of backrest 418 or seat bottom, seat occupant is started Actuator 530 for nearside lumbar support mechanism 500.With reference to Fig. 9 and Figure 10, when actuator 530 is activated, mechanism 500 It can be in any position between fully retracted position (Fig. 9) and fully extended position (Figure 10).It is powered to motor 534 When, the engagement of worm gear 546 rotates drive shaft 554, to rotate main shaft 560 simultaneously.If lumbar support mechanism 500 is started Less support is provided to retract, then main shaft 560 rotates in a first direction.If lumbar support mechanism 500 started with Extend and more supports are provided, then main shaft 560 is rotate in the opposite direction.Starting in either direction is that user can Utilize electric activation switches selection.As in the fig. 1 embodiment, the rotation of main shaft 560 translates sliding block 580,584, sliding block 580, the edge 600,604 of 584 groove 590,592,594,596 and main shaft guide rail 562 interacts, thus a sliding block 580, it 584 advances on proximal direction (520), and another sliding block 580,584 is advanced on distal direction (524).

In order to extend lumbar support mechanism 500, seat occupant starts the mechanism to rotate clockwise main shaft 560 (from remote Side direction 524 is observed), this causes, and nearside sliding block 580 is distally advanced along main shaft 560 and distal side sliding block 584 is along main shaft 560 advance to nearside, i.e. sliding block 580,584 and their respective attachment drag-line 620,624 is closer to each other.With sliding block 580, 584 assemble, interlude 650 contact laterally outside silk 444, thus force flexure pad 440 the region crossed over by mechanism 500 to Before, as in Fig. 9 as shown in arrow 692.When nearside sliding block 580 contacts buffer 612, motor 534 stops, this makes main shaft 560 rotation stops.As shown in figure 9 and in figure 10, hook end 668 allows the connection around vertical support member 434,438 to rotate, To allow the smooth movement of lumbar support mechanism 500 when lumbar support mechanism 500 is advanced forward.Although it is not shown, with The spring of one in drag-line 620,624 or the two coupled in series can allow for limited deflection and provide to tenant " give way (give) " is to enhance the comfort level of the device.

In order to retract lumbar support mechanism 500 to reduce lumbar support amount, seat occupant starter mechanism 500 is with counterclockwise Live spindle 560, this cause nearside sliding block 580 to nearside advance and distal side sliding block 584 distally advance, i.e., sliding block 580, 584 and they respective attachment drag-line 620,624 separate.As sliding block 580,584 becomes to be spaced further apart, from drag-line 620, 624 interlude 650 mitigates against the pressure of laterally outside silk 444, and in response, and flexure pad 440 retracts backward, such as exists In Figure 10 as shown in arrow 694.As described earlier, when nearside sliding block 580 contacts buffer 608, motor 534 stops.

Lumbar support mechanism 500,502 is operating independently, and the two can be passed through they of completeness by operation Range.For example, lumbar support mechanism 500,502 both of which can extend, both of which can be retracted or one can It is fully or partly retracted when another completely or partially extends.With reference to Figure 11, nearside lumbar support mechanism 500 In fully extended position, at the same distal side lumbar support mechanism 502 in fully retracted position (in order to observe, the horse of mechanism 502 Up to being not present).As shown in Figure 12, nearside lumbar support mechanism 500 is in fully retracted position, while distal side lumbar support Mechanism 502 is in fully extended position.Between the range shown in figs. 11 and 12, any degree of mechanism 500,502 it is only Vertical extension/retraction is all possible.By 500,502 points of vertical distance D opened of mechanism₁It is about 50mm, but for concrete application For, there can be greater or lesser amplitude.

As lumbar support system 100, during the process that profile pad 440 is advanced, extend and from being retracted into from prolonging Reach retraction, the holding of drag-line 620,624 is arranged in essentially identical plane, and the of each drag-line 620,624 Angle beta (such as seeing Fig. 9) between one end 630 and second end 634 keeps obtuse angle.

In some applications, by the operation of mechanism substantially as described earlier, as shown in Figure 13, single waist branch Support mechanism such as mechanism 500 can be used individually.

Rigid support silk 1170 includes: a pair of of hook 1174,1176, and the pair of hook 1174,1176 is used for and basket 1040 Lower base member 1052 engages；And rail portion, the rail portion have the closed slide 1180,1184 of the first and second connections.Support Silk 1170 further forms ring 1190 between guide rail 1184 and hook 1176.It is suitable for accommodating guide rail 1180,1184 with size The extremity piece 1200 of semi-circular grooves 1204 includes the guide portion 1210 to extend back from the first face 1214.Guide portion 1210 is additionally Rest upon the upper end 1220 of main shaft 1150.Supporting wire 1170 is operably linked to driving assembly 1130 via bracket 1144.Sliding block 1160 opposed channel 1230 is matched with the guide rail 1180,1184 of supporting wire 1170, so that 1160 energy of sliding block during operation Enough translational motions.First buffer 1234 adjacent with bracket 1144 provides the first travel limit of sliding block 1160, and with draw It leads the second adjacent buffer 1238 of portion 1210 and second travel limit is provided, these limit limit the moving range of sliding block 1160.

Drag-line 1250 includes first end 1254, second end 1258 and drag-line ontology 1260.First end 1254 and connector 1264 are integrally formed or are fixed to the connector 1264, and connector 1264 is connected to the ontology of sliding block 1160, with sliding block 1160 is mobile.Drag-line ontology 1260 is from first end 1254 by guide portion 1210 towards the top edge 1048 of basket 1040 and by logical Road 1270 extends, and the access 1270 is by the generally laterally bracket component 1274 of centrally-located near the edge of basket 1,040 1048 It limits.Access 1270 is formed with arch drag-line contact portion 1278, so that drag-line 1250 rotates about 180 ° and along lower base member 1052 direction is advanced downwards, i.e., the angle between the first and second ends 1254,1258 is about 0 °, but can be with range from about 0 ° to about 15 °.The second end 1258 of drag-line 1250 is firmly connected to eyelet 1282, receives spring by the eyelet 1282 Spring 1290 is connected to ring 1190 by the second end 1294 of 1290 first end 1286, spring 1290.

The electric actuation preferably with backrest or seat bottom adjacent positioned such as is used for other embodiments discussion preceding Switch, seat occupant start the actuator 1130 for being used for lumbar support mechanism 1100.With reference to Figure 22 and 24 (there are also 25 and 26), When actuator 1130 is activated, mechanism 1100 can be in any position being fully retracted between (Figure 22) and fully extended (Figure 24) In setting.When being powered to motor 1134, the engagement of worm gear rotates drive shaft and rotates main shaft 1150 simultaneously.If lumbar support Mechanism 1100 is activated in retraction and provides less support, then main shaft 1150 rotates in a first direction.If lumbar support Mechanism 1100 is activated in extension and provides more supports, then main shaft 1150 rotates in a second opposite direction.Any Starting on direction is that user can be selected using electric activation switches.The rotation of main shaft 1150 translates sliding block 1160, sliding The channel 1204 of block 1160 is translated along guide rail 1180,1184.

In order to extend lumbar support mechanism 1100, seat occupant starter mechanism is with live spindle in a second direction 1150, this causes sliding block 1160 to move down towards base member 1052.As sliding block 1160 is mobile, the contact branch of drag-line ontology 1260 The arch portion 1278 of frame 1274.By drag-line ontology 1260 act on the first and second ends 1254,1258 in drag-line 1250 it Between tension apply downward force on bracket 1274.Because bracket 1274 is fixedly secured to basket 1040 (specifically in top edge Near 1048), so when drag-line 1250 is fixed to base member 1052 indirectly by supporting wire 1170 simultaneously, even by elasticity The top edge 1048 for connecing the basket 1040 of the promotion of device 1044 is slided along the vertical support member 1020,1024 of frame section 1010, from And extend the waist contact area of basket 1040 forward, to support the lumbar region of seat occupant as shown in Figure 24.Work as cunning When block 1160 contacts buffer 1234, motor 1134 stops, this stops the rotation of main shaft 1150.

In order to retract lumbar support mechanism 1100 to reduce lumbar support amount, seat occupant actuating mechanism 1100 is Live spindle 1150 on one direction, this causes sliding block 1160 to move up towards top edge 1048.With sliding block 1160 such as this journey Into the pressure from drag-line ontology 1260 against arch portion 1278 mitigates, and basket 1040 retracts backward in response, such as further It is shown in Figure 25 and 26, this makes top edge 1048 along vertical support member 1020,1024 upwards.Such as retouched preceding It states, when sliding block 1160 contacts buffer 1238, motor 1134 stops.

In some applications, bracket 1274 is substituted by strut rail (not shown), which crosses at least the one of top edge 1048 Part, for strut rail preferably in the form of the second rigid filaments, which is presented the connection of the second end 1294 for spring 1290 Connect surface.Using the drag-line 1250 shorter than showing and describing in Figure 22-26, driven motor 1134 with live spindle 1150 simultaneously When translator slider 1160, shorter drag-line 1250 is not acted on bracket 1274 by drag-line ontology 1260 as previously described, But it is acted on by spring 1290 (that is, second end 1294) directly to strut rail and therefore to the application of the top edge 1048 of basket 1040 Power, identically to extend and to retract basket 1040.In other words, carbine 1294 is attached to strut rail rather than supporting wire 1170 On ring 1190.Alternatively, in some applications, the second end 1258 of drag-line is during operation directly (in no spring In the case where 1290) in top edge 1048 apply downward force.

Figure 27 shows another lumbar support for vehicle seat with the feature similar with the feature of system 1000 System 1300.For the sake of clarity, system 1300 will renumber.System 1300 includes separate frame portion 1310, the frame section 1310 have the vertical support member 1320,1324 for installing flexible waist support basket 1340.Basket 1340 is included in top edge Elastomeric connector 1344 near 1348 and the elastomeric connector near lower base member 1,352 1350,1351, to promote Basket 1340 along vertical support member 1320,1324 traveling.As indicated, lumbar support system 1300 includes adjustable waist branch Support mechanism 1400.

Rigid support silk 1470 includes: a pair of of hook 1474,1476 for engaging with lower base member 1352；And have first With the first rail portion of the closed slide 1480,1484 of the second connection；And the closed slide with the first and second connections 1486,1488 the second rail portion.It is respectively adapted to accommodate the semi-circular grooves of guide rail 1180,1184 and 1186,1188 with size First and second extremity pieces 1500 of slot 1504 each include the guide portion 1510 to extend back.The guidance of each extremity piece 1500 Portion 1510 additionally rests upon the upper end 1520,1522 of corresponding main shaft 1450,1452.Supporting wire 1470 can be grasped via bracket 1444 It is connected to driving assembly 1430,1432 with making.

The opposed channel 1530 of sliding block 1460 is matched with the guide rail 1480,1484 of supporting wire 1470, to draw during operation Play the translational motion of sliding block 1460.First buffer 1534 adjacent with bracket 1444 provides the first traveling pole of sliding block 1460 Limit, and second buffer 1538 adjacent with the guide portion 1510 of associated extremity piece 1500 provides the second travel limit, this A little limit limit the moving range of sliding block 1460.

The opposed channel 1540 of block 1462 is matched with the guide rail 1486,1488 of supporting wire 1470.Block 1462 includes across block 1462 aperture 1542, the aperture 1542 receive strut rail 1544, which is coupled to vertical support member 1320,1324 And extend between vertical support member 1320,1324.Strut rail 1544 is fixed to support member 1320,1324 with band 1546. Therefore, block 1462 is fixed also relative to frame section 1310.It such as will be further detailed, the first buffer 1548 and the second buffer 1549 determine travel limit associated with block 1462.

Drag-line 1550 includes first end 1554, second end 1558 and drag-line ontology 1560.First end 1554 and connector 1564 are integrally formed or are fixed to the connector 1564, and connector 1564 is connected to the ontology of sliding block 1460 with sliding block 1460 is mobile.Drag-line ontology 1560 is from first end 1554 by being associated the guide portion 1510 of extremity piece 1500 and towards basket 1340 Top edge 1348 extends.Drag-line ontology 1560 passes through access 1570, and the access 1570 is by near the edge of basket 1,340 1348 Generally laterally the bracket component 1574 of centrally-located limits.Access 1570 is formed with arch drag-line contact portion 1578, thus drag-line 1550 about 180 ° of rotations are simultaneously advanced downwards along the direction of lower base member 1352, i.e., between the first and second ends 1554,1558 Angle be about 0 °, but can be with range from about 0 ° to about 15 °.The second end 1558 of drag-line 1550 is firmly connected to hook 1582, which is received by the aperture 1586 of the extremity piece 1500 contacted with main shaft 1452.

The electric actuation preferably with backrest or seat bottom adjacent positioned such as is used for other embodiments discussion preceding Switch, seat occupant start the actuator 1430,1432 for being used for lumbar support mechanism 1400.With reference to Figure 27 and 29, work as actuating When device 1430 is activated, mechanism 1400 can be in any position being fully retracted between (Figure 27) and fully extended (Figure 29). When the motor 1434 to actuator 1430 is powered, the engagement of worm gear rotates drive shaft and rotates main shaft 1450 simultaneously.If Lumbar support mechanism 1400 is activated in retraction and provides less support, then main shaft 1450 rotates in a first direction.If Lumbar support mechanism 1400 is activated in extension and provides more supports, then main shaft 1450 revolves in a second opposite direction Turn.Starting in either direction is that user can be selected using electric activation switches.The rotation of main shaft 1450 makes sliding block 1460 translations, the channel 1504 of sliding block 1460 and guide rail 1480,1484 interact.

In order to extend lumbar support mechanism 1400, seat occupant starter mechanism is with live spindle in a second direction 1450, this causes sliding block 1460 to move down towards base member 1352.As sliding block 1460 is mobile, the contact branch of drag-line ontology 1460 The arch portion 1578 of frame 1574.By drag-line ontology 1560 act on the first and second ends 1554,1558 in drag-line 1550 it Between tension apply downward force on bracket 1574.Because bracket 1574 is fixedly secured to basket 1340 (specifically in top edge Near 1348), so when drag-line 1550 is fixed to base member 1352 indirectly by supporting wire 1470 simultaneously, by elasticity The top edge 1348 for the basket 1340 that connector 1344 promotes is slided along the vertical support member 1320,1324 of frame section 1310, To extend the waist contact area of basket 1340 forward, to support the lumbar region of seat occupant as shown in Figure 29.When When sliding block 1460 contacts buffer 1534, the motor 1434 of actuator 1430 stops, this stops the rotation of main shaft 1450.

In order to retract lumbar support mechanism 1400 to reduce lumbar support amount, seat occupant starter mechanism 1400 is Live spindle 1450 on one direction, this causes sliding block 1460 to move up towards top edge 1348.With sliding block 1460 such as this journey Into the pressure from drag-line ontology 1560 against arch portion 1578 mitigates, and basket 1340 retracts backward in response, this to push up Edge 1348 is along vertical support member 1320,1324 upwards.As described earlier, when sliding block 1460 contacts buffer 1538 When, the motor 1434 of actuator 1430 stops.

With reference to Figure 27 and 30, supporting mechanism 1400 and basket 1340 can be vertically adjusted, to allow to position as institute's phase The seat occupant flexibility of basket 1340.When actuator 1432 is activated, mechanism 1400 can completely reduce (Figure 27) and It is increased in any position between (Figure 30) completely.When the motor 1434 to actuator 1432 is powered, the engagement of worm gear makes to drive Moving axis rotation simultaneously rotates main shaft 1452 simultaneously.If lumbar support mechanism 1400 is activated in reduction, main shaft 1452 is first It is rotated on direction.If lumbar support mechanism 1400 is activated in raising, main shaft 1452 rotates in a second opposite direction. Starting in either direction is that user can be selected using electric activation switches.The rotation of main shaft 1452 makes 1400 He of mechanism Basket 1340 is translated relative to fixed block 1462, and the channel 1540 of fixed block 1462 and guide rail 1486,1488 interact.

In order to increase lumbar support mechanism 1400 and supporting element 1340, seat occupant starter mechanism is in a second direction Live spindle 1452.The screw thread of main shaft 1452 and the interaction of the screw thread for the block 1462 for being fixed to frame section 1310 cause entirely Mechanism 1400 and basket 1340 are translated up relative to block 1462.When without the actuating of other actuator 1430, in drag-line 1550 When interior tension is maintained, the Extendible Extent of basket 1340 is remained unchanged.Connector 1344,1350,1351 operationally contacts perpendicular Straight support member 1320,1324, to allow and guide the moving upwards in basket 1340 vertically oriented as institute's phase of basket 1340 Waist contact area.When 1548 contact block 1462 of buffer, the motor 1434 of actuator 1432 stops, this makes main shaft 1452 Rotation stop.In order to reduce lumbar support mechanism 1400, seat occupant starter mechanism 1400 to rotate in a first direction Main shaft 1452, this causes mechanism 1400 and basket 1340 to translate downwards relative to block 1462.As described earlier, when buffer 1549 connects When contact block 1462, the motor 1434 of actuator 1432 stops.

With reference to Figure 30 and 31, pass through the actuating of actuator 1430 as previously described, basket 1340 can fully retract and Extend in any height in the vertical range determined by buffer 1548,1549.Point of actuator 1430,1432 is not required The operation opened, so that adjusting and retraction/extension can be completed at the same time vertically.
