This disclosure relates generally to furniture. More specifically, and without limitation, this disclosure is directed to chairs.
Many chairs can be uncomfortable to use for extended periods of time due to the 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 a 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.
Another object of the disclosure is to provide a seating system having a compact internal reclining mechanism configured to support an occupant in upright and reclined positions.
Yet another object of the disclosure is to provide a seating system that is strong, robust, and durable.

In the following detailed description of the embodiments, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration specific embodiments in which the disclosure may be practiced. The embodiments of the present disclosure described below are not intended to be exhaustive or to limit the disclosure to the precise forms in the following detailed description. Rather, the embodiments are chosen and described so that others skilled in the art may appreciate and understand the principles and practices of the present disclosure. It will be understood by those skilled in the art that various changes in form and details may be made without departing from the principles and scope of the invention. It is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures. For instance, although aspects and features may be illustrated in or described with reference to certain figures or embodiments, it will be appreciated that features from one figure or embodiment may be combined with features of another figure or embodiment even though the combination is not explicitly shown or explicitly described as a combination. In the depicted embodiments, like reference numbers refer to like elements throughout the various drawings.
It should be understood that any advantages and/or improvements discussed herein may not be provided by various disclosed embodiments, or implementations thereof. The contemplated embodiments are not so limited and should not be interpreted as being restricted to embodiments which provide such advantages or improvements. Similarly, it should be understood that various embodiments may not address all or any objects of the disclosure or objects of the invention that may be described herein. The contemplated embodiments are not so limited and should not be interpreted as being restricted to embodiments which address such objects of the disclosure or invention. Furthermore, although some disclosed embodiments may be described relative to specific materials, embodiments are not limited to the specific materials or apparatuses but only to their specific characteristics and capabilities and other materials and apparatuses can be substituted as is well understood by those skilled in the art in view of the present disclosure.
It is to be understood that the terms such as “left, right, top, bottom, front, backrest, side, height, length, width, upper, lower, interior, exterior, inner, outer, and the like as may be used herein, merely describe points of reference and do not limit the present invention to any particular orientation or configuration.
As used herein, “and/or” includes all combinations of one or more of the associated listed items, such that “A and/or B” includes “A but not B,” “B but not A,” and “A as well as B,” unless it is clearly indicated that only a single item, subgroup of items, or all items are present. The use of “etc.” is defined as “et cetera” and indicates the inclusion of all other elements belonging to the same group of the preceding items, in any “and/or” combination(s).
As used herein, the singular forms “a,” “an,” and “the” are intended to include both the singular and plural forms, unless the language explicitly indicates otherwise. Indefinite articles like “a” and “an” introduce or refer to any modified term, both previously-introduced and not, while definite articles like “the” refer to a same previously-introduced term; as such, it is understood that “a” or “an” modify items that are permitted to be previously-introduced or new, while definite articles modify an item that is the same as immediately previously presented. It will be further understood that the terms “comprises,” “comprising,” “includes,” and/or “including,” when used herein, specify the presence of stated features, characteristics, steps, operations, elements, and/or components, but do not themselves preclude the presence or addition of one or more other features, characteristics, steps, operations, elements, components, and/or groups thereof, unless expressly indicated otherwise. For example, if an embodiment of a system is described as comprising an article, it is understood the system is not limited to a single instance of the article unless expressly indicated otherwise, even if elsewhere another embodiment of the system is described as comprising a plurality of articles.
It will be understood that when an element is referred to as being “connected,” “coupled,” “mated,” “attached,” “fixed,” etc. to another element, it can be directly connected to the other element, and/or intervening elements may be present. In contrast, when an element is referred to as being “directly connected,” “directly coupled,” “directly engaged” etc. to another element, there are no intervening elements present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” “engaged” versus “directly engaged,” etc.). Similarly, a term such as “operatively”, such as when used as “operatively connected” or “operatively engaged” is to be interpreted as connected or engaged, respectively, in any manner that facilitates operation, which may include being directly connected, indirectly connected, electronically connected, wirelessly connected, or connected by any other manner, method or means that facilitates desired operation. Similarly, a term such as “communicatively connected” includes all variations of information exchange and routing between two electronic devices, including intermediary devices, networks, etc., connected wirelessly or not. Similarly, “connected” or other similar language particularly for electronic components is intended to mean connected by any means, either directly or indirectly, wired and/or wirelessly, such that electricity and/or information may be transmitted between the components.
It will be understood that, although the ordinal terms “first,” “second,” etc. may be used herein to describe various elements, these elements should not be limited to any order by these terms unless specifically stated as such. These terms are used only to distinguish one element from another; where there are “second” or higher ordinals, there merely must be a number of elements, without necessarily any difference or other relationship. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of example embodiments or methods.
Similarly, the structures and operations discussed herein may occur out of the order described and/or noted in the figures. For example, two operations and/or figures shown in succession may in fact be executed concurrently or may sometimes be executed in the reverse order, depending upon the functionality/acts involved. Similarly, individual operations within example methods described below may be executed repetitively, individually, or sequentially, to provide looping or other series of operations aside from single operations described below. It should be presumed that any embodiment or method having features and functionality described below, in any workable combination, falls within the scope of example embodiments.
As used herein, various disclosed embodiments may be primarily described in the context of chairs. However, the embodiments are not so limited. It is appreciated that the embodiments may be adapted for use in other applications which may be improved by the disclosed structures, arrangements and/or methods. The system is merely shown and described as being used in the context of chairs for ease of description and as one of countless examples.

In this example arrangement, lower axle 310 has an elongated cylindrical shape extending between opposing ends 316. In this example arrangement, lower axle 310 extends through lower set of holes 138 in side portions 118 of rear support member 102 of backrest 14. In this example arrangement, lower axle 310 extends outward from the sides of backrest 14 through slotted track 224 in frame 16 to connect with rollers 312 positioned within frame 16 at opposing ends 316 of lower axle 310.
While some arrangements may be primarily shown or described as having a continuous axle 310 extending across backrest 14 and outward from the sides of backrest 14, the embodiments are not so limited. Rather, it is contemplated that in one or more arrangements, lower guide assembly 300 may include two separate lower axles 310 connected to each side of backrest 14 to facilitate connection with rollers 312 and slotted track 224, for example as shown in
Rollers 312 are formed of any suitable size, shape, and design and are configured to connect with opposing ends 316 of lower axle 310 and move smoothly within frame 16 along the path of slotted track 224. In one or more various arrangements, rollers 312 may implemented using various means or methods for rolling known in the art including but not limited to, for example, wheels, balls, bearings, or a combination thereof. In one or more various arrangements, rollers 312 may be attached to opposing ends 316 of lower axle 310 using various methods or means for connecting 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.
Upper guide assembly 302 is formed of any suitable size, shape, and design and is configured to connect with and guide an upper portion of backrest 14 along a designated path when backrest 14 is moved from an upright position to a reclined position. In the arrangement shown, as one example, upper guide assembly 302 includes an upper axle 330, links 332, and hinged connections 336, among other components.
In this example arrangement, upper axle 330 has an elongated cylindrical shape extending between opposing ends 338. In this example arrangement, upper axle 330 extends through upper set of holes 136 in side portions 118 of rear support member 102 of backrest 14. In this example arrangement, upper axle 330 extends outward from the sides of backrest 14.
In this example arrangement, links 332 have an elongated generally rectangular planar shape extending between upper ends 342 and lower ends 344. In this example arrangement, lower ends 344 of links 332 are connected to the opposing ends 338 of upper axle 330. In this example arrangement, hinged connections 336 connect upper ends 342 of links 332 to arms 246 at holes 270. In one or more arrangements, edges and/or corners of link 332 are rounded to eliminate sharp edges or corners that may be contacted by an occupant of system 10.
Hinged connections 336 are formed of any suitable size, shape, or design, and are configured to facilitate connection of upper ends 342 of links 332 with arms 246, while permitting links 332 to pivot relative to arms 246. 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 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 connected to upper axle 330 and a second end 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, where tube 368 is operably connected to second ends of torsion springs 352, a tensioner gear mechanism 374 (not shown), 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 (not shown). Tensioner gear mechanism 374 (not shown) 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 (not shown) 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 (not shown) 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 (not shown). 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 through 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.
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 one arrangement shown, as one example, stop feature 358 may be locking assembly 360. Locking assembly 360 is formed of any suitable size, shape, and design and is configured to hold backrest 14 in various intermediate positions between the fully reclined position and the fully upright position. This essentially converts system 10 from a reclining chair to a non-reclining chair when desired by the occupant of system 10. In the arrangement shown, as one example, locking assembly 360 includes a movable body 361 with teeth 362, and a stationary member 363 with indents 364. In the arrangement shown, as one example, locking assembly 360 is configured to connect to reclining mechanism 20 through upper axle 330. More specifically, in the arrangement shown as one example, upper axle 330 extends through apertures in both movable body 361 and stationary member 363, thereby connecting locking assembly 360 to reclining mechanism 20. Movable body 361 is formed of any suitable size, shape, and design and is configured to move along at least a portion of upper axle 330 and between a locked position and an unlocked position. In the arrangement shown, as one example, movable body 361 includes teeth 362.
Teeth 362 are formed of any suitable size, shape, and design and are configured to be inserted into indents 364 of stationary member 363 in order to lock backrest 14 in an intermediate position. In the arrangement shown, as one example, movable body 361 includes six teeth 362, configured to lock backrest 14 at six different intermediate positions, however any other number of teeth 362 may be present to lock backrest 14 at any number of intermediate positions. In the arrangement shown, as one example, teeth 362 extend outward from movable body 361 in a direction toward stationary member 363. In the arrangement shown, as one example, teeth 362 are chamfered, such that teeth 362 form a pointed end. The purposes of teeth 362 being chamfered is so teeth 362 can more easily be inserted into indents 364 (i.e., perfect alignment is not needed). The chamfered shaped of teeth 362 help to guide teeth 362 into indents 364 properly.
Stationary member 363 is formed of any suitable size, shape, and design and is configured to help facilitate the locking of backrest 14 at intermediate positions. In the arrangement shown, as one example, stationary member 363 includes indents 364. Indents 364 are formed of any suitable size, shape, and design and are configured to receive and hold teeth 362 therein when movable body 361 is in a locked position. Similar to teeth 362, in the arrangement shown as one example there are six indents 364 which help define six intermediate positions, however any other number of indents 364 may be present in order to lock backrest 14 at any number of intermediate positions. Additionally, similar to teeth 362, indents 364 are chamfered in the arrangement shown as one example. The chamfered shape of indents 364 and teeth 362 helps facilitate proper alignment of, insertion into, and engagement of teeth 362 with indents 364. The chamfered indents 364 help guide teeth 362 as they are being inserted into indents 364. In the arrangement shown, when movable body 361 is in the unlocked position, teeth 362 are disengaged from indents 364 of stationary member 363 and backrest 14 is freely movable between the upright position and the reclined position. When a user wants to lock backrest 14 at an intermediate position, the user can move backrest 14 to the desired position and then move movable body 361 of locking assembly 360 inward along upper axle 330. When movable body 361 is moved inward along upper axle 330, teeth 362 are inserted into, and held in locked engagement with, indents 364 of stationary member 363 and backrest 14 is locked in place at the desired position, which can be any position between fully upright, fully reclined, or anywhere in between fully upright and fully reclined. When the user desires to reposition backrest 14 again, the user can move movable body 361 outward along upper axle 330 to the unlocked position, thereby disengaging teeth 362 from indents 364 and allowing backrest 14 to freely move again.
In the arrangement shown, as one example, movable body 361 extends a length from an inward end (which is the end having teeth 362) and an outward end. The length of movable body 361 is as such to give a user a fair amount of surface area to properly engage and operate movable body 361 between an unlocked position and a locked position.
In an unlocked position, movable body 361 rotates with upper axle 330 of reclining mechanism 20. This is accomplished by movable body 361 having a non-round opening through its approximate middle that fits over the non-round exterior surface of upper axle 330 within close and tight tolerances that allow movable body 361 to slide a length along upper axle 330 but prevent relative rotation between upper axle 330 and movable body 361. In the unlocked position movable body 361 is disengaged from stationary member 363 and backrest 14 is in an unlocked position (i.e., backrest 14 is free to move between a fully upright position and a fully reclined position).
In a locked position, movable body 361 is engaged with stationary member 363 of locking assembly 360, thereby inhibiting the rotation of movable body 361. As noted above, movable body fits over upper axle 330 with close and tight tolerances that allow movable body 361 to slide a length along upper axle 330 but prevent relative rotation between upper axle 330 and movable body 361. When movable body 361 is engaged with stationary member 363, movable body 361 is inhibited from rotating which inhibits rotation of upper axle 330 of reclining mechanism 20. In this configuration, backrest 14 is in a locked position at the set position which can be the fully upright position, the fully reclined position, or any other position in between the fully upright position and the fully reclined position.
While locking assembly 360 and its various components have been described according to the arrangement shown, as one example, locking assembly 360 and its various components may be formed of any other size, shape, or design in order to facilitate the locking of backrest 14 at intermediate positions between the fully upright position and the fully reclined position.
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 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.
An alternative arrangement of system 10 is presented in various figures shown as additional examples. The alternative arrangements presented are similar to the system 10 described above and shown in various other figures, and therefore unless specifically stated otherwise herein, the prior teaching and disclosure apply equally to these alternative arrangements. That is, the alternative arrangements described below are configured to be used with the same or similar seat 12, backrest 14, arm covers 18, and reclining mechanism 20 and the like, with the primary difference relating to frame 16 as is described herein.
In one or more alternative arrangements shown in one or more figures, as examples, frame 16 is formed of any suitable size, shape, and design and is configured to operably connect with and support seat 12, backrest 14, and reclining mechanism 20 of system 10 to provide seating for an occupant of system 10. In the arrangement shown, as one example, frame 16 is a chair frame formed of elongated bar stock and having a base section 170, a seat support section 172, and an arm support section 174, among other components.
Base Section 170 of frame 16 is formed of any suitable size, shape, and design and is configured to provide stable support of system 10 on a floor. In the arrangement shown, as one example, base section 170 includes front legs 180, lower front corners 182, side bars 184, lower rear corners 186, and rear legs 188, among other components.
In this example arrangement, front legs 180 have a generally elongated rectangular shape extending from upper ends 190, connected to seat support section 172, to lower ends 192 connected to lower front corners 182. In this example arrangement, lower front corners 182 have a generally elongated rectangular shape extending from lower ends 192 and curving rearward before connecting to front ends 198 of side bars 184. In this example arrangement, side bars 184 each have an elongated rectangular shape extending from front end 198, where side bars 184 are connected to lower front corner 182, to a rear end 200, where side bars 184 are connected to lower rear corner 186. In this example arrangement, lower rear corners 186 have a generally elongated rectangular shape extending from rear ends 200 of side bars 184 and curving upward before connecting to lower ends 206 of rear legs 188. In this example arrangement, rear legs 188 have an elongated rectangular shape extending from lower ends 206, where rear legs 188 are connected to lower rear corners 186, to upper ends 208, where rear legs 188 connect with seat support section 172. In this example arrangement, rear legs 188 extend forward at an angle as rear legs 188 extend from lower ends 206 to upper ends 208.
Seat support section 172 of frame 16 is formed of any suitable size, shape, and design and is configured to support and facilitate connection of frame 16 with seat 12, while operably connecting arm support section 174 to base section 170. In the arrangement shown, as one example, seat support section 172 includes upper rear corners 214 and side bars 220, among other components.
In this example arrangement, upper rear corners 214 have a generally elongated rectangular shape extending from upper ends 208 of rear legs 188 and curving forward before connecting to rear ends 234 of side bars 220. In this example arrangement, side bars 220 each have an elongated rectangular shape extending from rear ends 234, where side bars 220 are connected to center corners 218, to a front end 236, where side bars 220 are connected to upper ends 190 of front legs 180.
Arm support section 174 of frame 16 is formed of any suitable size, shape, and design and is configured to provide an arm rest for an occupant seated in seat 12 while operably connecting backrest 14 with frame 16. In the arrangement shown, arm support section 174 includes front vertical sections 238, lower front bends 240, front sloped sections 242, upper front bends 244, a pair of arms 246, rear bends 248, and rear sloped sections 252.
In this example arrangement, front vertical sections 238 have a generally elongated rectangular shape extending from a lower end 260 connected to upper ends 190 of front legs 180 to an upper end 262.
In this example arrangement, front sloped sections 242 each have a contoured elongated shape extending rearward at an angle from a lower end 256, where front sloped sections 242 connect to upper end 262 of front vertical section 238, to an upper end 258, where front sloped sections 242 connect to upper front bend 244.
In this example arrangement, front bends 244 have a generally elongated rectangular shape extending from upper end 258 of front sloped sections 242 and curving rearward before connecting to front end 264 of arms 246.
In this example arrangement, arms 246 each have an elongated rectangular shape extending from front end 264 to rear ends 266, where arms 246 are connected to rear bends 248. In this example arrangement, arms 246 include holes 270 located proximate to rear ends 266 and extending sideways through arms 246 to facilitate connection with link 332 of upper guide assembly 302 of reclining mechanism 20.
In this example arrangement, arms 246 have recesses 450 in a bottom surface proximate to rear ends 266. Recesses 450 are formed of any suitable size, shape, and design and are configured to receive and conceal link 332 of upper guide assembly 302 when backrest 14 is moved to the upright position. In the arrangement shown, as one example implementation, recesses 450 in each arm 246 includes a first channel 452 extending upward from a bottom surface of arms 246 from a rearward end 454 to a forward end 456. In this example arrangement, recesses 450 in each arm 246 also include a second channel 458 extending from first channel 452 proximate to forward end 456 to an inner side edge of arm 246. The second channel 458 is configured to receive an end 338 of upper axle 330, where upper axle 330 connects with link 332, when backrest 14 is moved to the upright position. In this manner upper guide assembly 302 is concealed from view when backrest is not reclined, thereby giving system a more aesthetically pleasing appearance.
In this example arrangement, rear bends 248 connect arms 246 to rear sloped sections 252. In this example arrangement, rear bends 248 have a generally elongated rectangular shape extending from rear end 266 of arms 246 and curving downward and then forward before connecting to an upper end 276 of rear sloped section 252.
In this example arrangement, rear sloped sections 252 have an elongated rectangular shape extending from upper end 276 to a lower end 278, where rear sloped sections 252 connect with upper rear corners 214 of seat support section 172.
In this example arrangement, rear sloped sections 252 include a slotted track 224 positioned on an inner side of upper rear corners 214. As discussed in more detail with reference to reclining mechanism 20, slotted track 224 is configured to facilitate guiding a lower end of backrest 14 along a designated path when being moved from an upright position to a reclined position. In the example arrangement shown, slotted track 224 is configured to receive a guide member 314 operably connected to an end 316 of lower axle 310 within slotted track 224. Guide member 314 is formed of any suitable size, shape, and design, and is configured to operably hold and guide end 316 of lower axle 310 along slotted track 224 as backrest 14 is moved between reclined and upright positions. In the arrangement shown, guide member 314 is an elongated generally rectangular shaped member configured to be received and move smoothly within slotted track 224 with minimal binding. In the arrangement shown, guide member 314 is connected to end 316 of lower axle 310 by a fastener extending through a hole 318 and into end 316 of lower axle 310. However, the embodiments are not so limited. Rather, it is contemplated that in one or more arrangements guide member 314 may be connected to end 316 of lower axle 310 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.
In one or more arrangements, the range of movement of backrest may be restricted using inserts 460 (not shown). Inserts 460 are formed of any suitable size, shape, and design, and are configured to be inserted into and held within slotted track 224 to restrict the range of motion of guide member 314 within slotted track 224. As an illustrative example, in one or more arrangements, a user may insert an insert 460 into a lower end of slotted track 224 to restrict the distance that guide member 314 can travel downward, and thereby restrict the amount that backrest can be reclined. Conversely, as another example, in one or more arrangements, the user may insert an insert 460 into an upper end of slotted track 224 to restrict the distance that guide member 314 can travel upward, and thereby restrict the amount that backrest can be moved toward the fully upright position. In this manner, positioning and range of motion of backrest 14 may be customized to suit the preferences of a user.
In one or more arrangements, upper guide assembly 302 of reclining mechanism 20 has link 332 positioned to move backrest 14 into a locked upright position when force is applied to a rear portion of backrest 14, where force is typically applied to backrest when a user is seated upright. In this example arrangement, link 332 of upper guide assembly 302 is configured to permit reclining mechanism 20 to be moved to the reclined position when force is applied to an upper portion of backrest 14, where force is typically applied o backrest when a user leans backward while seated.

In the arrangement shown, as one example, back plate 548 is a generally planar member which has a generally flat and planar bottom edge 588, opposing sides 590, and a top edge 592. In the arrangement shown, as one example, bottom edge 588 extends between opposing sides 590. In the arrangement shown, as one example, opposing sides 590 extend upward and at an angle from bottom edge 588 and opposing sides 590 extent in approximate parallel spaced relation to one another. In the arrangement shown, as one example, top edge 592 extends between opposing sides 590 in a generally convex curved manner, however top edge 592 has a recess 595 therein.
In the arrangement shown, as one example, back plate 548 is generally smaller than front plate 542. In the arrangement shown, as one example, back plate 548 is positioned such that top edge 592 of back plate 548 is generally aligned with top edge 554 of front plate 542. However, opposing sides 590 of back plate 548 are shorter than opposing sides 552 of front plate 542. Back plate 548 is configured to be smaller than front plate 542 in order for fasteners, which can be screws, bolts, nails, or any other type of fastener, to extend through front plate 542 near the bottom portion of cartridge 540 and past back plate 548 in order to connect to pocket 530 within inner surface 528 of second legs 482. Additionally, recess 595 is present within the top edge 592 of back plate 548 in order to allow an additional fastener to be passed through front plate 542 at the top portion of cartridge 540 and past back plate 548 in order to connect to pocket 530 within inner surface 528 of second legs 482.
In the arrangement shown, as one example, back plate 548 includes hole 593 configured to receive the portion of node 574 extending outward from the back surface 578 of articulating link 544. In this way, articulating link 544 may be securely and pivotally attached to back plate 548.

Fasteners 596 are formed of any suitable size, shape, and design and are configured to connect back plate 548 to front plate 542. More specifically, fasteners 596 extend through openings 594 of back plate 548 and are received within reception member 556 of front plate 542.
While cartridge 540 has been described according to the arrangement shown, as one example, it will be understood by those skilled in the art that modifications may be made to cartridge 540 which do not depart from the scope of this invention.
In the arrangement shown, as one example, cartridge 540 must be assembled and then inserted onto frame 16. In the arrangement shown, as one example, the portion of node 574 extending outward from the back surface 578 of articulating link 544 is positioned and inserted into hole 593 of back plate 548. After this, bumper 546 is operably connected to back plate 548 through any means or method of attachment, such as adhesion, screwing, nailing, or any other method. Once bumper 546 is attached to back plate 548, guide wheel 586 is then positioned within slot 584 of articulating link 544. Once this is done, front plate 542 should be positioned such that the opening 558 of front plate 542 is aligned with the portion of node 574 extending outward from the front surface 576 of articulating link 544 and this portion of node 574 may then be inserted into opening 558. Next, reception members 556 of front plate 542 should be aligned with openings 594 of back plate 548 and fasteners 596 may then be inserted through openings 594 and into reception members 556. Once fasteners 596 are inserted through back plate 548 and into reception members 556 of front plate 542, cartridge 540 is assembled.
Once cartridge 540 has been assembled, cartridge 540 is then attached to upper axle 330 extending out of backrest 14. In the arrangement shown, as one example, upper axle 330 is aligned with recess 582 of reception member 580 of articulating link 544 and upper axle 330 is then inserted into recess 582. Once upper axle 330 is in recess 582, pin 583 is inserted through second edge 572 of articulating link 544, and pin 583 engages upper axle 330 within recess 582, thereby securing upper axle 330 in recess 582.
Next, cartridge 540 is to be aligned with pocket 530 within inner surface 528 of second legs 482. Cartridge 540 is then placed into pocket 530. In this angle, front plate 542 of cartridge 540 is wholly or partially covered by backrest 14. A user can rotate backrest 14 in order to view front plate 542, and more specifically bossed holes 560 of front plate 542. When the user can view and access bossed holes 560, the user can secure cartridge 540 to pocket 530 using fasteners such as screws, bolts, nails, or any other type of fastener, which are placed through bossed holes 560 of front plate 542 and driven into second legs 482. The user will need to move backrest 14 between multiple positions in order to insert fasteners into all of the bossed holes 560. Once fasteners have been placed into all bossed holes 560, cartridge 540 is connected to pocket 530 and is ready for use.

Front plate 600 is formed of any suitable size, shape, and design and is configured to allow for the movement of backrest 14 between an upright position and a reclined position while helping contain additional components of cartridge 540. In the arrangement shown, as one example, front plate 600 has a bottom edge 608, opposing sides 610, and a top edge 612. In the arrangement shown, as one example, bottom edge 608 is a generally flat and planar edge which extends between opposing sides 610. Opposing sides 610 are generally flat and planar edges which extend at an angle upward from bottom edge 608 until they reach top edge 612 and opposing sides 610 extend in approximate parallel planar spaced relation to one another. In the arrangement shown, as one example, top edge 612 extends between opposing sides 610 and has a generally convex curvature as it extends across. In the arrangement shown, as one example, front plate 600 includes a generally flat and planar front surface 614 and a back surface 616. Front plate 600 may be formed of any material suitable for use as a plate, including various metallic materials such as stainless steel, aluminum, chromium, or any other metallic material, or various non-metallic materials such as a plastic material, a fiberglass material, or any other non-metallic material.
In the arrangement shown, as one example, front plate 600 includes bossed holes 620, a slot 622 having a first edge 624 and a second edge 626, a first protruded surface 628, a second protruded surface 630, and holes 632.
In the arrangement shown, as one example, front plate 600 includes bossed holes 620. Bossed holes 620 are formed of any suitable size, shape, and design and are configured to receive a fastener therethrough to facilitate connection of cartridge 540 to second legs 482. In the arrangement shown, as one example, bossed holes 620 extend through front plate 600 from the front surface 614 to the back surface 616.
In the arrangement shown, as one example, front plate 600 includes a slot 622. Slot 622 is formed of any suitable size, shape, and design and is configured to receive a portion of gear 602 therein and allow for the movement of gear 602 along slot 622 as the backrest 14 moves between an upright position and a reclined position. In the arrangement shown, as one example, slot 622 extends through front plate 600 from the front surface 614 to the back surface 616. In the arrangement shown, as one example, slot 622 extends a length from a first edge 624 to a second edge 626. In the arrangement shown, as one example, first edge 624 is located at the top right portion of slot 622 and second edge 626 is located at the bottom left portion of slot 622. In the arrangement shown, as one example, a portion of gear 602 is placed through slot 622 and can travel along slot 622 as the backrest 14 is moved from an upright position to a reclined position.
In the arrangement shown, as one example, slot 622 has a width slightly larger than the circumference of the portion of gear 602 extended through slot 622, which allows gear 602 to move along slot 622 with relatively little friction.
In the arrangement shown, as one example, front plate 600 includes a first protruded surface 628 and a second protruded surface 630. First protruded surface 628 and second protruded surface 630 are formed of any suitable size, shape, and design and are configured to help facilitate engagement between front plate 600 and back plate 604 while allowing gear 602 to be properly engaged and operable when positioned between front plate 600 and back plate 604. In the arrangement shown, as one example, first protruded surface 628 extends a first distance outward from the back surface 616 of front plate 600 and the second protruded surface 630 extends a second distance outward from the back surface 616 of front plate 600. In the arrangement shown, as one example, the first distance is greater than the second distance, meaning the first protruded surface 628 extends outward from back surface 616 a greater distance than the second protruded surface 630. However, in various other arrangements, as examples, the first protruded surface 628 and the second protruded surface 630 may extend outward from back surface 616 the same distance, or the second protruded surface 630 may extend outward from back surface 616 a greater distance than the first protruded surface 628.
In the arrangement shown, as one example, when the front plate 600 and back plate 604 are brought together, the first protruded surface 628 of the front plate 600 is positioned adjacent the back surface 640 of back plate 604. Likewise, when front plate 600 and back plate 604 are brought together, the second protruded surface 630 of front plate 600 is positioned adjacent the protruded surface 656 of back plate 604. In this arrangement, as one example, gear 602 is able to be positioned in between front plate 600 and back plate 604 such that the teeth 636 of gear 602 engage with the teeth 658 of the protruded surface 656 of back plate 604. That is, the first protruded surface 628 and second protruded surface 630 of front plate 600, and the protruded surface 656 of back plate 604 create a space that allows the teeth 636 of gear 602 to engage with the teeth 658 of the protruded surface 656 of back plate 604 while still allowing gear 602 to rotate and move along slot 622, rather than be held in place due to friction between gear 602 and front plate 600 and/or back plate 604.
In the arrangement shown, as one example, front plate 600 also includes holes 632. Holes 632 are formed of any suitable size, shape, and design and are configured to help facilitate connection of front plate 600 to back plate 604. In the arrangement shown, as one example, holes 632 are generally circular holes configured to receive bolts, screws, or various other fasteners configured to hold front plate 600 and back plate 604 in secured engagement. However, holes 632 may be formed of any other shape or size in order to accommodate various fasteners to hold front plate 600 and back plate 604 together.
Gear 602: In the arrangement shown in
In the arrangement shown, as one example, gear 602 is generally cylindrical in shape and has teeth 636 extending outward from gear 602. Teeth 636 are formed of any suitable size, shape, and design and are configured to help facilitate movement of gear 602 when backrest 14 is moving between a reclined position and an upright position. In the arrangement shown, as one example, teeth 636 extend outward from gear 602 in a generally helical manner, however in other arrangements teeth 636 may extend outward from gear 602 in a straight manner or in any other manner. In the arrangement shown, as one example, teeth 636 are configured to engage with teeth 658 of the protruded surface 656 of back plate 604. When the backrest 14 of system 10 is being reclined or moved to an upright position, gear 602 will move in a path along slot 622 and the teeth 636 of gear 602 rotate, in the process engaging with teeth 658 of the protruded surface 656 of back plate 604, in order to facilitate smooth and quiet reclining of backrest 14.
In the arrangement shown, as one example, gear 602 includes engagement feature 638. Engagement feature 638 is formed of any suitable size, shape, and design and is configured to facilitate connection between gear 602 and reclining mechanism 20. In the arrangement shown, as one example, engagement feature 638 is a hole generally in the shape of a hexagon which is configured to receive upper axle 330 of upper guide assembly 302 of reclining mechanism 20, thereby facilitating engagement between gear 602 and reclining mechanism 20. While engagement feature 638 is shown as being a hole generally in the shape of a hexagon, it will be understood by those of skill in the art that engagement feature 638 may be a hole in any other shape, and engagement feature 638 may be formed of any other shape or design configured to engage upper axle 330. In this way, gear 602 of cartridge 540 is connected to reclining mechanism 20 and reclining mechanism 20 and cartridge 540 work together to smoothly facilitate the movement of backrest 14 between a reclined and upright position.
Back Plate 604: In the arrangement shown, as one example, cartridge 540 includes back plate 604. Back plate 604 is formed of any suitable size, shape, and design and is configured to help facilitate connection of the various components of cartridge 540. In the arrangement shown, as one example, back plate 604 is a generally planar member which has a bottom edge 642, opposing sides 644, and a top edge 646. In the arrangement shown, as one example, bottom edge 642 extends between opposing sides 644 and opposing sides 644 are generally flat and planar edges which extend at an angle upward from bottom edge 642 until they reach top edge 646, and opposing sides 644 extend at an approximate parallel planar spaced relation to one another. In the arrangement shown, as one example, top edge 646 extends between opposing sides 644 in a generally convex curved manner, however top edge 646 has a recess 648 therein. In the arrangement shown, as one example, back plate 604 also includes a generally flat and planar front surface 641 and a back surface 640.
In the arrangement shown, as one example, back plate 604 is generally smaller than front plate 600. In the arrangement shown, as one example, back plate 604 is positioned such that top edge 646 of back plate 604 is generally aligned with top edge 612 of front plate 600. However, opposing sides 644 of back plate 604 are shorter than opposing sides 610 of front plate 600. Back plate 604 is configured to be smaller than front plate 600 in order for fasteners, which can be screws, bolts, nails, or any other type of fastener, to extend through front plate 600 near the bottom portion of cartridge 540 and past back plate 604 in order to connect to pocket 530 within inner surface 528 of second legs 482. Additionally, recess 648 is present within the top edge 646 of back plate 604 in order to allow an additional fastener to be passed through front plate 600 at the top portion of cartridge 540 and past back plate 604 in order to connect to pocket 530 within inner surface 528 of second legs 482.
In the arrangement shown, as one example, back plate 604 also includes openings 650. Openings 650 are formed of any suitable size, shape, and design and are configured to allow fasteners 652 to pass therethrough. Fasteners 652 are formed of any suitable size, shape, and design and are configured to connect back plate 604 to front plate 600. More specifically, fasteners 652 extend through openings 650 of back plate 604 and are received within holes 632 of front plate 600
In the arrangement shown, as one example, the back surface 640 of back plate 604 includes a recessed surface 654 and a protruded surface 656 having teeth 658. In the arrangement shown, as one example, recessed surface 654 is formed into back surface 640 and extends in a path generally similar to the path of slot 622. In the arrangement shown, as one example, recessed surface 654 is provided to allow gear 602 to slide smoothly along back surface 640 of back plate 604 as it also moves along slot 622. That is, recessed surface 654 is provided such that when gear 602 moves along slot 622, gear 602 experiences reduced friction and resistance from back surface 640 due to recessed surface 654.
In the arrangement shown as one example, back surface 640 also included a protruded surface 656. Protruded surface 656 is formed of any suitable size, shape, and design and is configured to help facilitate engagement between front plate 600 and back plate 604 while allowing gear 602 to be properly engaged and operable when positioned between front plate 600 and back plate 604. In the arrangement shown, as one example, protruded surface 656 extends a distance outward from the back surface 640 of back plate 604. As described herein, when front plate 600 and back plate 604 are brought together, protruded surface 656 of back plate 604 is positioned adjacent second protruded surface 630 of front plate 600.
In the arrangement shown, as one example, protruded surface 656 also includes teeth 658. Teeth 658 are formed of any suitable size, shape, and design and are configured to engage with teeth 636 of gear 602. In the arrangement shown, as one example, teeth 658 extend across an edge of protruded surface 656 along a path generally parallel to the path of slot 622 in order for teeth 658 to engage teeth 636 of gear 602 while gear 602 is positioned within and moving along slot 622. In the arrangement shown, as one example, teeth 658 of protruded surface 656 also help facilitate the smooth movement of backrest 14 between the upright and reclined positions.
While cartridge 540 has been described according to the alternative arrangement shown, as one example, it will be understood by those skilled in the art that modifications may be made to cartridge 540 which do not depart from the scope of this invention.
In the arrangement shown in
Back plate 604 may then be aligned such that teeth 636 of gear 602 and teeth 658 of protruded surface 656 of back plate 604 are in alignment. In this position, the openings 650 of back plate 604 and the holes 632 of front plate 600 should also be in alignment, thereby allowing fasteners 652 to be inserted through openings 650 and holes 632, in order to secure front plate 600 and back plate 604 together. Once fasteners 652 are placed through openings 650 of back plate 604 and holes 632 of front plate 600, the first protruded surface 628 of front plate 600 will rest adjacent the back surface 640 of back plate 604 and the second protruded surface 630 of front plate 600 will rest adjacent the protruded surface 656 of back plate 604.
Once cartridge 540 has been assembled, cartridge 540 is then attached to upper axle 330 extending out of backrest 14. In the arrangement shown, as one example, upper axle 330 is aligned with engagement feature 638 of gear 602 and upper axle 330 is then inserted into engagement feature 638.
Next, cartridge 540 is to be aligned with pocket 530 within inner surface 528 of second legs 482. Cartridge 540 is then placed into pocket 530. In this angle, front plate 600 of cartridge 540 is wholly or partially covered by backrest 14. A user can rotate backrest 14 in order to view front plate 600, and more specifically bossed holes 620 of front plate 600. When the user can view and access bossed holes 620, the user can secure cartridge 540 to pocket 530 using fasteners such as screws, bolts, nails, or any other type of fastener, which are placed through bossed holes 620 of front plate 600 and driven into second legs 482. The user will need to move backrest 14 between multiple positions in order to insert fasteners into all of the bossed holes 620. Once fasteners have been placed into all bossed holes 620, cartridge 540 is connected to pocket 530 and is ready for use.
