In Fig. 5, finger 515 and snap-gauge 517 are only exemplary, and backrest installing connecting rods 510 may include design The various other configurations to control the inclination of backrest installing connecting rods 510 and sway are contacted with stop element 513 in different parts. For example, replacing being formed that it is similar to be formed notch can be formed in the periphery from the periphery of backrest installing connecting rods 510 element outstanding The first joint edge in finger 515 and the second joint edge similar to snap-gauge 517.Also that is, backrest installing connecting rods 510 wrap Periphery and body portion 509 are included, and a kerf can extend inwardly into body portion 509 from periphery.

In one embodiment, the part of backrest installing connecting rods 510 engaged with stop element 513 be configured to by relative to The amount of swaying of upright position is limited in about 49 degree.For example, finger 515 (that is, first joint edge) and snap-gauge 517 are (that is, second Joint edge) the distance between formed a gap, the gap limit stop element 513 backrest installing connecting rods 510 pivot When migrate path.This, which migrates path, can be configured to the amount of swaying that control allows.In one embodiment of the invention, work as use Diameter is about 0.450 " stopper section when, stop part 513 migrate distance in about 0.80 " to about 1.20 " between. Therefore, which can also be with this distance and diameter ratio.Stop element 513 can be used alone, or combine the other of described in the text Stopper section uses, to limit the motion range of linkage mechanism.

In embodiment, preceding lifting linking member 440 includes rear portion 446, front 445 and middle part 447.As described above, preceding lifting The middle part 447 of connecting rod 440 is pivotably coupled to the front 531 of overlap joint connecting rod 535 at pivot 436.Preceding lifting linking member 440 exists Pivot 441 is in the front 901 that rear portion 446 is rotatably coupled to seat mount plate (referring to Fig. 9).In addition, preceding lifting linking member 440 at pivot 452 before front 445 is pivotably coupled to pivot link 450 top 456.Preceding pivot link 450 is in pivot Axis 453 is in the front end 415 that lower part 457 is rotatably coupled to substrate 410 (referring to Fig. 9).

In situation of the invention, preceding pivot link 450, which is included at pivot 451, is pivotably coupled to bracket connecting rod The middle part 458 of 460 lower part 463.The bellcrank before top 464 is pivotably coupled at pivot 461 of bracket connecting rod 460 485.Typically, preceding bellcrank 485 includes top 481, lower part 483 and front 482, as shown in Figure 7.Preceding bellcrank 485 Top 481 bracket connecting rod 460 is pivotably coupled at pivot 461, as described in immediately above.Preceding bellcrank 485 Middle part 482 at pivot 487 by preceding bellcrank 485 be rotatably coupled to seat mount plate 400 middle part 409 (referring to Fig. 9).The lower part 483 of preceding bellcrank 485 is pivotably coupled to the rear end 591 of pedal kinematic link 590 at pivot 486. The front end 592 of pedal kinematic link 590 is pivotably coupled to the rear stool connecting rod 120 of pedal component 200 at pivot 125.

With continued reference to Fig. 4-7, it will illustrate the operation of seat adjustment component 500 according to an embodiment of the invention.It is first First, the power of taking one's seat backward of operator's initiation can be received at backrest.As described above, backrest installing connecting rods 510 cooperate with mirror image connection The backrest installing connecting rods of the supplement of motivation structure are used to support the backrest of seat unit.At one of manually adjustable seat unit In embodiment, balanced threshold should be overcome to bias backrest installing connecting rods backward by being oriented in user's rearward force at backrest 510, it is achieved in the movement from extended position (Fig. 6) to reclined position (Fig. 5).Balanced threshold substantially can be by leaning on back backward Downward user's weight ratio in user's power and seat limits.In operation, the downward force of the weight of user pushes down on Dynamic seat mount plate 400, and user acts on the rearward force by back and passes through backrest installing connecting rods 510, rear controls connecting rod 520, the mutual of rear bellcrank 530, rear pivot link 540 and substrate 410 is connected and upwardly and forwardly pushes seat mount plate 400.It (it should be noted that balanced threshold can be applied to manually adjust in style seat unit, and automates and adjusts style seat Unit comes to adjust linkage mechanism 100 between extended position and reclined position dependent on motor or other linear actuators.) because This, power backward overcomes downward power to cause the adjusting of seat unit.

Once user by by means of offset his/her weight in seat and applying adequately power backward and or Tilted backwards by back and overcome balanced threshold, can realize 510 around the pivot 401 of backrest installing connecting rods movement backward (from The visual angle of Fig. 5, which is seen, to be rotated clockwise) and start the adjusting from extended position to reclined position.Back rotation generates around the pivot 511 torque.Torque is transformed into the power of transversal orientation by rear controls connecting rod 520.Therefore, rear controls connecting rod 520 is pacified in backrest The power of transversal orientation is transmitted between load bar 510 and rear bellcrank 530.Typically, rear controls connecting rod 520 is in rear bellcrank The clockwise torque of around the pivot 536 is formed on 530.Clockwise torque is transformed by bellcrank 530 afterwards is guided from rear pivot The downward power that connecting rod 540 passes through, rear pivot link 540 rotate at pivot 542 around the rear end of substrate 410 416.

The rotation enables seat mount plate 400 during being adjusted to reclined position from extended position relative to substrate 410 forwardly and upwardly translate.In embodiment, connecting rod 510,520 and 540 and rear bellcrank 530 are designed to pacify seat Loading board 400 translates, so that seat is kept with substrate 410 when being adjusted to complete reclined position from the position TV at substantially consistent Tilt angle biasing.In addition, connecting rod 510,520 and 540 and rear bellcrank 530 be designed to make seat mount plate 400 with than The speed that the back rotation of backrest installing connecting rods 510 is big is translate forward, to realize Zero-wall clearance.

Translateing forward for seat mount plate 400 is also influenced by connecting rod 535,440 and 450.In a specific embodiment, rear clock The clockwise torque (being applied by user) of around the pivot 536 generates on overlap joint connecting rod 535 for pulling backward on shape crank 530 The power of the transversal orientation of preceding lifting linking member 440.This pulls the rotation counterclockwise for forming 440 around the pivot 441 of preceding lifting linking member backward, Preceding lifting linking member 440 is rotatably coupled to seat mount plate 400 by pivot 441.Rotation that this is counterclockwise is finally by bosom Stop element 421 prevents.When current lifting linking member 440 is contacted with bosom stop element 421, filling to reclined position is realized Divide and adjusts.The also premenstrual pivot link 450 of rotation counterclockwise of preceding lifting linking member 440 is formed laterally on the front end of substrate 410 415 The power of orientation.450 around the pivot 453 of pivot link is swung forward before the power of the transversal orientation makes, and is achieved in seat mount plate 400 Relative to translateing forward for substrate 410.

It is releasing after backward take one's seat power (for example, by user turned forward) of the back lower than balanced threshold, is allowing 510 biased forward of backrest installing connecting rods.Particularly, pivot link 540 is on rear bellcrank 530 after downward power of taking one's seat allows It pushes up, is rotated counterclockwise to form it.Rotation, which passes through the power of transversal orientation, counterclockwise is used to that backrest to be made to install The power for the transversal orientation that connecting rod 510 rotates in a counterclockwise manner.Also that is, the power of the transversal orientation applied by rear controls connecting rod 520 Backrest installing connecting rods 510 are enable to move forward to substantially upright orientation.In one example, prolong from rear bellcrank 530 The stop element (not shown) stretched prevents its continuous rotation when contacting with seat mount plate 400；To inhibit backrest being in Inclination further along when closure or extended position.

As described above, according to one embodiment of present invention, the size and geometry of various connecting rods and pivot are variable , this allows linkage mechanism 100 to be configured to realize desired functionality.Various connecting rods and pivot can be configured to control seat installation Forwardly and upwardly translational movement of the plate 400 relative to substrate 410.The linkage that Figure 17 A-17C shows linkage mechanism 100 has One example of various sizes of embodiment.The example of transformable size include: substrate 410 pivot 542 and pivot 453 it Between distance；The distance between the pivot 541 and 542 of pivot link 540 afterwards；The pivot 452 and 453 of preceding pivot link 450 it Between distance；Overlap the distance between the pivot 533 and 436 of connecting rod 535；Between the pivot 451 and 461 of preceding controls connecting rod 460 Distance；And the shape of preceding bellcrank 485.

In one embodiment of the invention, between rear 540 pivot 541 and 542 and the pivot of preceding pivot link 450 The distance between 452 and 453 influence the translateing forward relative to substrate of seat mount plate 400.For example, increasing pivot 541 and 542 The distance between and increase the distance between pivot 452 and 453 and facilitate the increased of seat mount plate 400 and translate forward, Which improve zero wall features (for example, wall clearance) of linkage mechanism.Reducing the distance between these pivots helps to improve The gap at seat and linkage.

In one embodiment of the invention, the distance between pivot 541 and 542 is in the English from about 7 inches to about 8.6 It is very little, preferably from about in the range of 7.3 inches to about 8.6 inches.For example, in one embodiment, in order to form seat mount plate The 400 desired amount of translateing forward, the distance between pivot 541 and 542 is about 8.6 inches, and more specifically about 8.573 English Very little (for example, Figure 17 A-17C).In another embodiment, in order to form desired seat gap value, between pivot 541 and 542 Distance is about 7.3 inches, and more specifically about 7.328 inches (for example, Fig. 4-7).In another embodiment of the present invention, pivot The distance between axis 452 and 453 is in from about 8.5 inches to about 10 inch, preferably from about 8.7 inches to about 9.8 inches of model In enclosing.For example, in one embodiment, in order to form the desired amount of translateing forward of seat mount plate 400, pivot 541 and 542 The distance between be about 9.8 inches, and more specifically about 9.804 inches (for example, Figure 17 A-17C).In another embodiment, In order to form desired seat gap value, the distance between pivot 541 and 542 is about 8.7 inches, and more specifically about 8.714 inches (for example, Fig. 4-7).

The distance between pivot can be defined as mutual ratio.For example, if the ruler of some or all linkage mechanisms 100 It is very little to be expanded or shunk with a coefficient, ratio may be used to determine the suitable distance between pivot.Therefore, of the invention one In a embodiment, the distance between pivot 541 and 542 and pivot 452 and 453 ratio are about 8.6:9.8, and the distance is than forming seat The desired amount of translateing forward of position mounting plate (for example, Figure 17 A-17C).In another embodiment of the invention, 541 He of pivot The distance between 542 and pivot 452 and 453 ratio are about 7.3:8.7, and the distance is than foring desired seat gap value (example Such as, Fig. 4-7).

In another embodiment of the invention, the phase of preceding pivot link 450, preceding lifting linking member 440 and preceding bellcrank 485 Other elements to position relative to linkage mechanism 100 shift forward.For example, the pivot 453 of preceding pivot link 450 may be arranged at More front on substrate 410, so that the increase of the distance between pivot 542 and pivot 453 and pivot 453 are towards the front of substrate 410 Further displacement.In addition, pivot 411 --- preceding lifting linking member 440 is attached on seat mount plate 400 at the pivot --- with And pivot 487 --- preceding bellcrank 485 is attached on seat mount plate 400 at the pivot --- shifts forward.

When constituting linkage mechanism, pivot link 450, preceding lifting linking member 440 and preceding bellcrank 485 are shifted forward before making Combining with other elements of linkage mechanism 100 can contribute to seat plate 400 and translates up relative to the higher of pedestal 410. For example, the distance between pivot 451 and 461 of bracket connecting rod 460 influences the translating up relative to substrate 410 of seat plate 400. Also that is, increasing the distance between pivot 451 and 461 facilitates translating up for increase, which improve the layout of linkage mechanism spies Sign.Spatial layout feature improvement is to be swayed because seat and chair are mobile at faster speed with balancing backrest.

In one embodiment of the invention, the distance between pivot 451 and 461 is in from about 8 inches to about 8.6 inch In the range of.For example, in one embodiment, the distance between pivot 451 and 461 is about 8.1 inches, and more specifically about 8.077 inches (for example, Fig. 4-7).In another embodiment, in order to increase translating up for seat mount plate 400, pivot 451 It is about 8.5 inches and more specifically about 8.535 inches (for example, Figure 17 A-17C) with the distance between 461.Therefore, Figure 17 A- One embodiment of the present of invention shown in 17C include pivot link 450 before making, preceding lifting linking member 440 and preceding bellcrank 485 to Anterior displacement (relative to embodiment shown in Fig. 4-7) (relative to seat mount plate 400) and will be between pivot 451 and 461 Distance is configured to about 8.5 inches.

Pivot link 450, preceding lifting linking member 440 and preceding bellcrank 485, which shift forward, before making can be used various modes It limits.For example, preceding bellcrank 485 can be attached on seat mount plate 400 by pivot 487 in various positions.In the first configuration In, about 4 inches of distance can extend (for example, Fig. 4-7) between pivot 487 and 536.It is shifted forward in preceding bellcrank 485 The second configuration (for example, Figure 17 A-17C) in, about 4.5 English may be present between the pivot 487 of pivot 536 and preceding bellcrank 485 Very little distance, so that pivot 487 shifts about 0.9 inch compared to the first configuration horizontally forward.

In the embodiment shown in Fig. 4-7, preceding bellcrank 485 includes cane shape configuration, bellcrank before which allows 485 rotate around starter bar 350.Also that is, the bending of preceding bellcrank 485 allow before bellcrank 485 from closed position (for example, Fig. 7) is moved to extended position (for example, Fig. 6) Shi Xuanzhuan without colliding with transmission mechanism 350.But current bell song When handle 485 is shifted forward to avoid interference starter bar 350, the bending section of preceding bellcrank 485 can be differently composed.Example Such as, slot can be positioned in the periphery of preceding bellcrank 485 or the middle part of preceding bellcrank 485 (for example, Figure 17 B and 17C) in, The slot provides when preceding bellcrank is rotated around starter bar 350 and migrates path for starter bar 350.

Referring now to Fig. 8 A-8D and 18A-18D, the automation form of linkage mechanism 100 is shown, and will be passed through now The following examples describe the automation form.In one embodiment, which includes pair as shown in figures 8 a-8d Linkage configuration.In an alternative embodiment, which includes the single-drive connecting rod structure as shown in Figure 18 A-18D Type.

Referring now to Fig. 8 A-8D, which may include linear actuators 300, which includes fixing Angle support 315, motor mechanism 320 on starter bar 350 (having been described above) and by motor mechanism 320 and motor starting The track 330 that device module 340 interconnects.In addition, the linear actuators may include keeping interval in substantially parallel each other The right motor link 380 and left motor link 390 for the relationship opened.In addition, settable be used as the table rested below seat unit The bearing assembly 600 on the basis on face.

Particularly, bearing assembly 600 can be used for accommodating linear actuators 300.Bearing assembly 600 shown in Fig. 8 may include Preceding cross member 610 and holding and the rear cross member 620 of preceding cross member 610 relationship in substantially parallel being spaced apart. Cross member 610 and 620 is used to for linear actuators 300 and substrate 410 being supported on above underlying surfaces.The bearing of Fig. 5 and 15 Casing 411 and 412 is arranged to promote linear actuators 300 and substrate 410 to the specified level above underlying surfaces.

In embodiment, the substrate 410 that cross member 610 and 620 is used as across linkage mechanism 100 joins with mirror image is incorporated in The crossbeam between the substrate of supplement within the organization is moved, which is arranged to be in substantially flat with linkage mechanism 100 The relationship in the ranks separated.In addition, cross member 610 and 620 can be formed by raw metal.Similarly, seat mount plate 400, base Plate 410 and multiple connecting rods including linkage mechanism 100 are usually such as struck out fashioned iron by raw metal and are formed.However, it should be understood that and It recognizes, well known any suitable rigid or firm material in furniture industry can be used to replace above-mentioned material.

In the embodiment of linear actuators 300, motor mechanism 320 is attached at preceding cross member by coupling or being fixed on Shell on 610 and protected.Motor mechanism 320 is operably coupled to the front end of track 330.The rear end of track 330 couples Or it is fixedly attached on rear cross member 620.Track 330 includes first stroke section 331 and second stroke section 332.Horse It is configured under the automation control of motor mechanism 320 longitudinally to translate along track 330 up to starter module 340 or slideably Engagement.Right motor link 380 and left motor link 390 are pivotably coupled to motor starter module 340, and by means of pivot Axis 382 and 392 is pivotably coupled to the angle support 383 and 393 (respectively) extended from angle support 315.

As described above, linkage mechanism 100, which is attached to, provides linkage mechanism 100 in reclined position, extended position and closure position The linear actuators 300 of power adjustment between setting.In one exemplary embodiment, motor starter module 340 is linking The automation of mechanism 100 migrates during adjusting toward and away from motor mechanism 320.In a particular embodiment, motor mechanism 320 control motor starter modules 340 migrate moving for section 331 and 332 along track 330.

In operation, the control signal in the user from seat unit or other places can trigger motor mechanism 320 and draw The longitudinal translation of motor starter module 340 is sent out, which generates the movement of linkage mechanism 100 again.It is as follows more abundant Ground discussion, it is first stage and second stage that sliding action, which is adjusted sequence,.During the first stage, motor mechanism 320 makes Motor starter module 340 is moved forward relative to motor mechanism 320, and the holding of motor mechanism 320 is substantially fixed at suitably Thus seat adjustment component 500 is adjusted to extended position (Fig. 6 and 8C) from closed position (Fig. 7 and 8B) by position.

Adjusting in first stage includes causing motor starter module 340 to migrate section 331 along the first of track 330 to indulge To traversing or sliding.Motor starter module 340 migrates this traversing in motor link 380 and 390 in section 331 first Place generates the thrust forwardly and upwardly pushed in angle support 315, is thus rotatably adjustable starter bar 350.Also that is, horse Migrate in section 331 up to starter module 340 first causes angle support 393 in pivot 392 towards the traversing of motor mechanism 320 On rotate clockwise (based on the view provided by Fig. 8 B), thus rotate clockwise angle support 315 and starter bar 350. Fig. 8 C provides the graphical representation of exemplary of angle support 393, angle support 315 and starter bar 350 after rotating clockwise from Fig. 8 B. As described above, starter bar 350 is adjusted by rotation control seat unit in closed position and extended position (that is, stretching, extension pedal Component 200) adjusting.

Once the stroke of first stage is substantially finished, second stage just starts.During second stage, motor starter Module 340 is moved forward relative to motor mechanism 320 again, and the holding of motor mechanism 320 is substantially fixed at appropriate location.? In embodiment, the adjusting in second stage includes causing second stroke section 332 of the motor starter module 340 along track 330 It is longitudinal traversing.Due to linkage mechanism full extension and starter bar 350 is prevented from further rotating, motor starter module 340 It is pushed forward in angle support 315 in this traversing generated at motor link 380 and 390 that second migrates in section 332 With upward thrust, translate starter bar 350 forwardly and upwardly relative to substrate 410.This of starter bar 350 is put down Move control seat unit between extended position and reclined position adjusting (that is, no user act on by back to Adjusting of the starting to seat adjustment component 500 under the auxiliary of power afterwards).For example, the forwardly and upwardly translation of starter bar 350 is drawn It plays seat plate 400 also forwardly and upwardly to move, this causes backrest installing connecting rods 510 to rotate clockwise on pivot 401 again.

In one example, the combination of motor mechanism 320, track 330 and motor starter module 340 is implemented as " electricity Dynamic " linear actuators 300.In this example, linear actuators 300 is by providing it the controller control of the manual operation of instruction System.These instructions can the offer in the actuating for detecting the controller of manual operation of user's starting.In addition, these instructions can make Linear actuators 300 executes the movement of complete first stage and/or second stage.Alternatively, described instruction can make it is linear activated Device 300 is partially completed the movement of first stage and/or second stage.Therefore, linear actuators 300 can be with independent Various positions that mode is moved in the stroke of first stage or second stage simultaneously maintain the position.

Although the combined particular configuration of motor mechanism 320, track 330 and motor starter module 340 has been described, It is understood and appreciated that, can be used and the other types of appropriate device of sequential adjustment is provided, and the embodiment of the present invention is not It is limited to linear actuators 300 as described herein.For example, the group of motor mechanism 320, track 330 and motor starter module 340 Close the implementable telescopic device to stretch out and withdrawing in a sequential manner.

In another embodiment of the invention, automation form includes the single-drive connecting rod configuration as shown in Figure 18 A-18D. Embodiment shown in Figure 18 A-18D and the similarity of Fig. 8 A-8D are that motor 1818 is attached on track 1820, and horse Up to before being attached on cross member 610, and one end of track 1820 is attached on rear cross member 620.In addition, motor starter Module 1812 is slidably attached on track 1820 so that motor starter module 1812 can using motor 1818 (or certain Other linear actuators) it is traversing along track 1820.In general, transmission connects as motor starter module 1812 crosses track 1820 Bar 1810 causes seat unit to move between folding position, extended position and reclined position.

The structure of embodiment shown in Figure 18 A-18D is different from Fig. 8 A-8D in all fields.For example, two kinematic links 380 and 390 (for example, Fig. 8 A) are replaced by single kinematic link 1810 (for example, Figure 18 A).In addition, in Figure 18 A-18D, motor Starter module 1812 and angle support 1814 and 1816 are differently composed.

In one embodiment of the invention, motor starter module 1812 includes that can slide motor starter module 1812 It is attached to the carrying ontology 1822 of track 1820 dynamicly.For example, carrying ontology 1822 may include a hole (not shown), work as motor When starter module 1812 is slidably coupled to track 1820, track 1820 is stretched out through the hole.In addition, motor starter mould Block 1812 includes a pair of installation tab 1824 and 1826 to extend back, and each installation tab includes corresponding hole.

Installing tab 1824 and 1826 includes gap positioned there between, and one end of kinematic link 1810 is entrenched in In the gap.The hole for installing tab 1824 and 1826 receives single fastener, which, which also passes through, is inserted into the gap Hole in the end of kinematic link 1810 is stretched out, and is opened so that kinematic link 1810 is pivotly attached at motor at pivot 1828 In dynamic device module 1812.Therefore, kinematic link 1810 is pivotly attached at motor starter mould at one end through pivot 1828 On block 1812.The opposite end of kinematic link 1810 is entrenched between angle support 1814 and 1816, and is existed by single fastener It is pivotly attached in angle support 1814 and 1816 at pivot 1830.In addition, two angle supports 1814 and 1816 are attached at angle On bracket 315.For example, corresponding single fastener can be used to be attached in angle support for each angle support 1814 and 1816.

The operation of linear actuators (for example, motor 1818) and single kinematic link 1810 is described now with reference to Figure 18 D, Figure 18 D shows driving member in the state diagram of different phase.For example, Figure 18 D show the mechanism in closed position 1840, stretch Set driving member when being conditioned between 1842 and reclined position 1844 in exhibition position.

In closed position 1840, thus the offset motor starter module 1812 backward of motor 1818 keeps the mechanism Closed position (for example, Fig. 1 and 7), and when kinematic link 1810 is such as in terms of the side of Figure 18 D in generally horizontal orientation. From closed position 1840, the starting of motor 1818 slides motor starter module 1812 towards motor 1818, thus should Mechanism operating is to extended position 1842.The relative level orientation of single kinematic link 1810 at least partly facilitates to open in motor The forward driving forces that dynamic device module 1812 applies when sliding towards motor 1818 to pivot 1830.Also that is, due to kinematic link 1810 keep it to be substantially horizontal orientation, so the forward force transformation distributed on pivot 1818 by motor starter module 1812 At the forward thrust acted on by kinematic link 1810 on pivot 1830.

Pushing forward on pivot 1830 from closed position 1840 causes angle support 1814 and 1816 suitable on pivot 1830 Hour hands pivot (based on the view provided in Figure 18 D), thus cause rotating clockwise for starter pipe 350.Such as in this explanation Described in the other parts of book, starter pipe 350 rotates clockwise the stretching for causing pedal component.The extension of pedal component Point limited by stop element 422 (Fig. 4) so that the engagement of stop element 422 and connecting rod 130 hinder starter pipe 350 into one Step rotation.

In one embodiment of the invention, transmission tube 350 rotates critical degree, by seat unit from normal place (for example, 1840) are adjusted to the position TV (for example, 1842).For example, in one embodiment, transmission tube 350 is from folding position 1840 rotate at least about 104 degree when being adjusted to extended position 1842.In another embodiment, transmission tube 350 is to be in about 104 degree Amount rotation in the range of to about 104.815 degree.Naturally, when the critical degree is close to constant (that is, about 104 degree), can lead to The length of angle support 1814 and 1816 is overregulated to adjust the operation of linkage mechanism.
