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, the term “or” includes one or more of the associated listed items, such that “A or B” means “either A or B”. As used herein, the term “and” includes all combinations of one or more of the associated listed items, such that “A and B” means “A as well as B.” The use of “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.

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, 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.

Similarly, it is contemplated that, in some various arrangements, first bracket 484 may be operably connected to backrest 14 using various methods or means that provide 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.
In this example arrangement, hinge mechanism 482 also includes a second bracket 486. Second bracket 484 is formed of any suitable size, shape, and design and is configured to operably connect to front support member 104 of backrest 14 and facilitate hinged connection with link 488. In the arrangement shown, as one example, second bracket 486 has a pair of generally parallel arms 498 that extend rearward from a forward end 502, where second bracket 486 is operably connected to the interior side of front support member 104, to a rearward end 500, where second bracket 486 is pivotally connected with link 488. In this example arrangement, an end of link 488 is positioned between rearward ends 500 of arms 498 of second bracket 486, where arms 498 are pivotally connected with link 488.
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.
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, 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 over-center 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.
