OVERVIEW OF THE DISCLOSURE:

Many chairs can be uncomfortable to use for extended periods of time due to their inability to properly support an occupant in both upright and reclined positions. Many chairs, such as office chairs, have backrests with reclining mechanisms to permit an occupant to sit with the backrest of the chair in a reclined position. However, such reclining mechanisms tend to be bulky external devices which are not aesthetically pleasing and, as such, may not be desirable for use in certain settings (e.g., in a dining room setting).

Therefore, for all the reasons stated above, and the reasons stated below, there is a need in the art for a seating system having a compact reclining mechanism concealed within the chair that is configured to support an occupant in upright and reclined positions.

It is an object of the disclosure to provide a seating system that improves upon the prior art.

Yet another object of the disclosure is to provide a seating system that is cost effective.

Another object of the disclosure is to provide a seating system that is high quality.

Yet another object of the disclosure is to provide a seating system that has a long useful life. Another object of the disclosure is to provide a seating system that is that is aesthetically pleasing.

In the arrangement shown, as one example, hinged connections 336 are formed by holes in link 332 which are positioned around opposing ends 338 of upper axle 330 and fasteners (e.g., bolts, screws, or any other fasteners) that are connected to holes of arms 246. However, the embodiments are not so limited. Rather, it is contemplated that hinged connections 336 may be implemented using any various methods or means for providing a hinged connecting known in the art.

Counterbalance Assembly 304:

Counterbalance assembly 304 is formed of any suitable size, shape, and design and is configured to apply a bias force sufficient to move backrest 14 to an upright position in the absence of a sufficient opposing force placed on backrest (e.g., by an occupant leaning backward).

In one arrangement shown, as one example, counterbalance assembly 304 includes a pair of arms 350 connected to first ends of torsion springs 352 positioned on upper axle 330 of upper guide assembly 302. In this example arrangement, arms 350 brace against lower axle 310 to prevent rotation of the first ends of torsion springs 352 when tensioned. In this example arrangement, the other ends of torsion springs 352 are connected to upper axle 330, which is connected to lower ends 344 of links 332 of upper guide assembly 302. When viewed from the left side torsion springs 352 are tensioned to rotate upper axle 330 and links 332 clockwise in absence of a sufficient opposing force, thereby moving backrest 14 to the upright position.

However, embodiments are not so limited. Rather, it is contemplated that in various different arrangements counterbalance assembly 304 may utilize various mechanisms to move backrest 14 to the upright position including but not limited to, for example, one or more springs, one or more gas pistons, one or more gas springs, one or more hydraulic pistons, one or more actuators, one or more solenoids, one or more pneumatic members, and/or any other force generating means or combination thereof. As an alternative example, in one or more arrangements, counterbalance assembly 304 includes torsion springs 352 and a tensioner assembly 348 operably connected to upper axle 330. In this example arrangement, torsion springs 352 each have a first end 354 connected to upper axle 330 and a second end 356 connected to a tensioner assembly 348. When viewed from the left side, torsion springs 352 are tensioned to rotate upper axle 330 and links 332 clockwise in absence of a sufficient opposing force, thereby moving backrest 14 to the upright position.

Tensioner assembly 348 is formed of any suitable size, shape, and design and is configured to apply tension to torsion springs 352 so as to cause torsion springs 352 to apply the bias force, by rotating upper axle 330, to move backrest 14 to an upright position in the absence of a sufficient opposing force placed on backrest 14. In the arrangement shown, as one example, tensioner assembly 348 includes a generally cylindrical tube 368 shape extending between opposing ends 370, where tube 368 is operably connected to second ends 356 of torsion springs 352, a tensioner gear mechanism 374, and a housing 366 among other components.

In this example arrangement, upper axle 330 extends through tube 368 and is configured to freely rotate relative to tube 368. In this example arrangement, tube 368 has a set of teeth 372 formed on an exterior surface of the tube 368.

In this example arrangement, tensioner assembly 348 includes a tensioner gear mechanism 374. Tensioner gear mechanism 374 is formed of any suitable size, shape, and design and is configured to engage teeth 372 of tube 368 and facilitate rotation of tube 368 to tension torsion springs 352. In the arrangement shown, as one example, tensioner gear mechanism 374 includes a worm gear 376 positioned to engage teeth 372 and cause tube 368 to rotate when the worm gear 376 is rotated by a user. In this example arrangement, worm gear 376 has a generally cylindrical shape extending from a forward end 378 to a rearward end 380 and has helical features 382 extending along an exterior surface of worm gear 376.

In this example arrangement, helical features 382 engage teeth 372 so as to cause tube 368 to rotate when worm gear 376 is rotated. In this example arrangement, worm gear 376 has a set of contact features 384 at forward end 378 to facilitate operable connection with a tool (e.g., a socket, wrench, screwdriver, or any other tool) for rotation of worm gear 376 by a user. In this example arrangement, features 384 at forward end 378 are accessible by a user via a hole 434 in backrest 14. For example, in one or more arrangements, features 384 at forward end 378 of worm gear 376 may be accessible from a hole 434 positioned in rear support member 102 of backrest support assembly 100. Additionally or alternatively, in one or more arrangements, features 384 at forward end 378 of worm gear 376 may be accessible from a hole 434 positioned in front support member 104 of backrest support assembly 100, which is accessible by removing cushion 106 from front support member 104. Additionally or alternatively, in one or more arrangements, features 384 at forward end 378 of worm gear 376 may be accessed by removing front support member 104 from rear support member 102 to expose tensioner assembly 348. However, the embodiments are not limited to these example arrangements. Rather it is contemplated that in various different arrangements may provide access for adjustment of tensioner assembly 348 using various other methods of means known in the art.

However, the arrangements are not so limited. Rather, it is contemplated that tensioner assembly 348 may be implemented using various different arrangements of components and/or may be positioned at various locations within system 10 to facilitate tensioning of torsion springs 352 of counterbalance assembly 304.

However, embodiments are not so limited. Rather, it is contemplated that in various different arrangements counterbalance assembly 304 may utilize various mechanisms to move backrest 14 to the upright position including but not limited to, for example, one or more springs, one or more gas pistons, one or more gas springs, one or more hydraulic pistons, one or more actuators, one or more solenoids, one or more pneumatic members, and/or any other force generating means or combination thereof.

Housing 366:

Housing 366 is formed of any suitable size, shape, and design and is configured to house cylindrical tube 368 and tensioner gear mechanism 374 and connect counterbalance assembly 304 with backrest 14. In the arrangement shown, as one example, housing 366 includes a front plate 400 and a back plate 402 forming a hollow interior 404 for housing cylindrical tube 368 and tensioner gear mechanism 374.

In this example arrangement, front plate 400 has a generally rectangular shape having a front surface 406 and a back surface 408, extending between a top 410, a bottom 412, and opposing sides 414. In this example arrangement, back plate 402 also has a generally rectangular shape having a front surface 418 and a back surface 420, extending between a top 422, a bottom 424, and opposing sides 426.

In this example arrangement, front surface 418 of back plate 402 and back surface 408 of front plate 400 each have a set of semi-cylindrical recesses 430 configured to receive and hold tube 368 of tensioner assembly 348. In this example arrangement, tube 368 is positioned in an opening defined by recesses 450, which extends between opposing sides 414/426 of front plate 400 and back plate 402. In this example arrangement, front surface 418 of back plate 402 and back surface 408 of front plate 400 also have circular recesses 432 configured to receive and hold worm gear 376. In this example arrangement, circular recesses 432 are positioned proximate to semi-cylindrical recesses 430 so helical features 382 of worm gear 376 engage teeth 372 of tube 368. More specifically, rearward end 380 of worm gear 376 is positioned within circular recess 432 of back plate 402 and forward end 378 of worm gear 376 is positioned in circular recess 432 of front plate 400. In this example arrangement, front plate 400 has an access hole 434 extending from front surface 406 into circular recess 432 of front plate 400 to provide access to contact features 384 of worm gear 376 to facilitate tensioning of torsion springs 352.

In one or more arrangements, front plate 400 and back plate 402 of tensioner assembly 348 are connected together by a set of fasteners 438 (e.g., bolts) that extend though holes 440 in front plate 400 and into back plate 402. However, the embodiments are not so limited. Rather, it is contemplated that in one or more arrangements front plate 400 and back plate 402 of tensioner assembly 348 may be connected using various methods or means including but not limited to, for example, screws, bolts, clamps, pins, rivets, welding, snap connectors, friction fit connectors, adhesives, chemical bonding, and/or any other process or means that results in a permanent of semi-permanent connection.

Stop Features 358:

In one or more arrangements, reclining mechanism 20 includes one or more stop features 358 (not shown) configured to facilitate positioning of seat 12 at one or more intermediate positions between the upright position and the reclined position. In one or more arrangements, as one example, stop feature(s) 358 may be recesses inside frame 16 that rollers 312 roll over when backrest 14 is moved between the upright and reclined positions. Due to a slightly larger amount of force required to move rollers 312 out of such recess, reclining mechanism 20 helps hold backrest 14 at one or more defined intermediate positions, thereby increasing reclining options for the occupant. However, the embodiments are not so limited. Rather, it is contemplated that reclining mechanism 20 may utilize various methods and means for holding backrest 14 at one or more intermediate positions including but not limited to, for example, recesses, protrusions, indents, detents, holes, compressive fittings, frictional stops, magnetic components, gears, latches, non-linear springs, non-linear cams and pulleys and/or any other suitable means or methods known in the art.

In Operation:

In operation, when backrest 14 is moved to an upright position, rollers 312 are moved within frame 16 upward and rearward along slotted track 224 to an upper end of slotted track 224, thereby moving a lower end of backrest 14 upward and rearward. At the same time, link 332 of upper guide assembly 302 moves an upper end of backrest 14 upward and forward. Conversely, when backrest 14 is moved to a reclined upright position, rollers 312 are moved downward and forward along slotted track 224 to a lower end of slotted track 224, thereby moving a lower end of backrest 14 downward and forward. At the same time, link 332 of upper guide assembly 302 moves the upper end of backrest 14 downward and rearward. This guided movement of backrest 14 between upright and reclined positioned facilitates a more natural movement of an occupant between upright and reclined positions.

In the arrangement shown, as one example, arms 498 are pivotally connected with link 488 by fasteners 504 that extend through holes in arms 498 and an end of link 488. However, the arrangements are not so limited. Rather, it is contemplated that arms 498 may be pivotally connected with link 488 using various methods and/or means including but not limited to, for example, fasteners, axles, bearings, hinges, joints, and/or any other method or mean for providing a hinged connection.

Similarly, it is contemplated that, in some various arrangements, second bracket 486 may be operably connected to front support member 104 using various method or means that provides a secure connection including, but not limited to, adhesive, glue, fasteners (e.g., screws, bolts, clamps, pins, rivets, and the like), welding, snap connectors, friction fit connectors, chemical bonding, and/or any other method or means of secure connection.

Link 488:

In this example arrangement, hinge mechanism 482 also includes a link 488. Link 488 is formed of any suitable size, shape, and design and is configured to operably connect to both the first bracket 484 and the second bracket 486. In the arrangement shown, as one example, link 488 has opposing ends 506 and extends between the forward end 494 of first bracket 484 and the forward end 502 of second bracket 486. In this example arrangement, opposing ends 506 of link 488 are positioned between forward end 494 of first bracket 484 and forward end 502 of second bracket 486, where each forward end is pivotally connected with link 488.

In the arrangement shown, as one example, the forward end 494 of first bracket 484 and forward end 502 of second bracket 486 are pivotally connected with link 488 by fasteners 496 and fasteners 504 that extend through holes in arms 490 of first bracket 484, arms 498 of second bracket 486, and opposing ends 506 of link 488. However, the arrangements are not so limited. Rather, it is contemplated that the forward end 494 of first bracket 484 and forward end 502 of second bracket 486 may be pivotally connected with link 488 using various methods and/or means including but not limited to, for example, fasteners, axles, bearings, hinges, joints, and/or any other method or mean for providing a hinged connection. Link 488 allows first bracket 484 and second bracket 486 to move and pivot around one another using link 488 when access assembly 476 is moved between an open and closed position.

In Operation:

In operation, a user may want to access the counterbalance assembly 304 of system 10 for any reason including but not limited to, for example, repairs or replacement of parts and/or to adjust force applied by counterbalance assembly 304. In one or more arrangements, access assembly 476 has hinge mechanism 482 positioned to move front support member 104 into an open position when force is applied to a bottom portion of cushion 106 and front support member 104.

In one or more arrangements, access assembly 476 has hinge mechanism 482 configured to hold front support member 104 in the closed position when an occupant is seated in the seating system 10. In one arrangement shown, the forward end 494 of first bracket 484 extends over the forward end 502 of second bracket 486 when front support member 104 is in a closed position. In this position, when a user applies forward force to a bottom portion of front support member 104, the forward end 502 of second bracket 486 is moved away from the forward end 494 of first bracket 484, towards front support member 104, thereby moving front support member 104 away from rear support member 102. In this position, a user may then move front support member 104 upward to disengage hook bracket 480 from receiving bracket 478 and permit upper edge 124 of front support member 104 to be moved forward and downward away from rear support member 102 to an open position. In this open position, the counterbalance assembly 304 may be accessed by a user.

To close front support member 104, a user may move front support member 104 towards rear support member 102. In this position, the user may engage hook bracket 480 and receiving bracket 478 by lifting the hook portion of hook bracket 480 over receiving bracket 478. In this position, the user may apply force to a lower edge 126 of front support member 104 to move front support member 104 towards rear support member 102 and into a closed position.

As lower edge 126 of front support member 104 is moved rearward, hinged connections of link 488 with first bracket 484 and second bracket 486 causes front support member 104 to be pulled downward, thereby tightening the engagement between receiving brackets 478 and hook brackets 480. Link continues to increase downward force applied to front support member 104 as lower edge 126 of front support member 104 is moved rearward until front support member is oriented vertically. As lower edge 126 of front support member 104 is moved further rearward closer to rear support member 102, link moves front support member 104 upward slightly, reducing the downward force applied to front support member 104. Due to the reduction in downward force, front support member 104 is held in this rearward closed position until a user purposefully applies forward force to move lower edge 126 of front support member 104 forward. In this manner, link 488, first bracket 484, and second bracket 486 operate as an overcenter lever to hold lower edge 126 of front support member 104 in a rearward closed position, where front support member 104 is securely attached to rear support member 102.
