The present invention relates generally to seating units, and more particularly to seating units with reclining capability.
Conventionally, a recliner chair will move from an upright position, in which the backrest is generally upright, to one or more reclined positions, in which the backrest pivots to be less upright. The movement of the seating unit between the upright and reclined positions is typically controlled by a pair of synchronized reclining mechanisms that are attached to the seat, backrest and base of the chair. Many recliners will have an extendable footrest or ottoman that provides support for the occupant's feet in the reclined position.
One particularly popular recliner is the “three-way” recliner, which has two reclined positions: an intermediate “TV position”, in which the footrest or ottoman of the chair is projected forwardly from the chair while the backrest remains substantially upright relative to the seat; and a “fully reclined position”, in which the backrest is less upright (i.e., it has been reclined to a shallower angle relative to the floor). In a “three-way” recliner, the backrest pivots relative to the seat as the chair takes its fully reclined position; this differs from a “two-way” recliner, in which the backrest and seat are rigidly fixed and do not pivot relative to one another as the chair moves to the fully reclined position, and from a “one-way” recliner, which typically has no intermediate “TV” position.
Early in the development of recliners, chair styles tended to be bulky, which limited the popularity of the recliner somewhat. Consumers have begun to demand reclining capability for less bulky chairs. Examples of sleeker, more modern recliner styles are illustrated in U.S. Pat. No. 7,669,922 to Murphy et al and U.S. Pat. No. 7,762,625 to Hoffman et al, the disclosures of each of which is hereby incorporated herein in its entirety.
As chair styling continues to evolve, it may be desirable to provide additional headrest configurations.
As a first aspect, embodiments of the present invention are directed to a reclining seating unit. The seating unit comprises: a base configured to rest on an underlying surface; a seat; a backrest; an ottoman; and a reclining mechanism comprising a plurality of pivotally interconnected links and attached to the base, seat, backrest and ottoman. The reclining mechanism is configured to move the seat, backrest and ottoman relative to the base between (a) an upright position, in which the backrest is generally upright, the seat is generally horizontal, and the ottoman is positioned beneath the seat and faces generally downwardly, (b) a TV position, in which the backrest is generally upright and the ottoman is generally horizontally disposed in front of the seat, and (c) a fully reclined position, in which the ottoman remains generally horizontally disposed in front of the seat and the backrest takes a shallower angle relative to the seat than in the upright and TV positions. The ottoman is between about 8 and 12 inches in length.
As a second aspect, embodiments of the present invention are directed to a reclining seating unit, comprising: a base configured to rest on an underlying surface; a seat; a backrest; an ottoman; and a reclining mechanism comprising a plurality of pivotally interconnected links and attached to the base, seat, backrest and ottoman. The reclining mechanism is configured to move the seat, backrest and ottoman relative to the base between (a) an upright position, in which the backrest is generally upright, the seat is generally horizontal, and the ottoman is positioned beneath the seat and faces generally downwardly, (b) a TV position, in which the backrest is generally upright and the ottoman is generally horizontally disposed in front of the seat, and (c) a fully reclined position, in which the ottoman remains generally horizontally disposed in front of the seat and the backrest takes a shallower angle relative to the seat than in the upright and TV positions. The lowermost point of the ottoman is at least 6 inches from the underlying surface when the seating unit is in the upright position:
As a third aspect, embodiments of the present invention are directed to a reclining seating unit, comprising: a base configured to rest on an underlying surface; a seat; a backrest; an ottoman; and a reclining mechanism comprising a plurality of pivotally interconnected links and attached to the base, seat, backrest and ottoman. The reclining mechanism is configured to move the seat, backrest and ottoman relative to the base between (a) an upright position, in which the backrest is generally upright, the seat is generally horizontal, and the ottoman is positioned beneath the seat and faces generally downwardly, (b) a TV position, in which the backrest is generally upright and the ottoman is generally horizontally disposed in front of the seat, and (c) a fully reclined position, in which the ottoman remains generally horizontally disposed in front of the seat and the backrest takes a shallower angle relative to the seat than in the upright and TV positions. The reclining mechanism includes a footrest linkage that comprises: front and rear ottoman drive links pivotally attached to the seat; a rear ottoman extension link pivotally attached to the front and rear ottoman drive links; an auxiliary ottoman extension link pivotally attached to the rear ottoman drive link; an auxiliary ottoman bracket pivotally attached to the auxiliary ottoman extension link and to the rear ottoman extension link; a main ottoman extension link pivotally attached to the auxiliary ottoman bracket; and a main ottoman bracket to which the ottoman is mounted, the main ottoman bracket being pivotally attached to the rear ottoman extension link and to the main ottoman extension link.
The present invention will be described more particularly hereinafter with reference to the accompanying drawings. The invention is not intended to be limited to the illustrated embodiments; rather, these embodiments are intended to fully and completely disclose the invention to those skilled in this art. In the drawings, like numbers refer to like elements throughout. Thicknesses and dimensions of some components may be exaggerated for clarity. Well-known functions or constructions may not be described in detail for brevity and/or clarity.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
In addition, spatially relative terms, such as “under”, “below”, “lower”, “over”, “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, elements described as “under” or “beneath” other elements or features would then be oriented “over” the other elements or features. Thus, the exemplary term “under” can encompass both an orientation of over and under. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. As used herein the expression “and/or” includes any and all combinations of one or more of the associated listed items.
Where used, the terms “attached”, “connected”, “interconnected”, “contacting”, “coupled”, “mounted” and the like can mean either direct or indirect attachment or contact between elements, unless stated otherwise.
In addition, some components of the seating units described herein (particularly mechanisms thereof) are illustrated herein as a series of pivotally interconnected links or members. Those skilled in this art will appreciate that the pivots between links or other components can take a variety of configurations, such as pivot pins, rivets, bolt and nut combinations, and the like, any of which may be suitable for use with the present invention.
Also, the shapes and configurations of the links themselves may vary, as will be understood by those skilled in this art. Further, some links may be omitted entirely in some embodiments, and additional links may be included in some embodiments.

Turning now to the reclining mechanism 21, each of the reclining mechanisms 21 is a mirror image of the other reclining mechanism 21 about a vertical plane that extends from the front of the chair 10 to the rear and is centered between the arms 29. In the interest of brevity, only one reclining mechanism 21 will be described herein, with the understanding that the discussion is equally applicable to the other reclining mechanism 21. Also, the reclining mechanism 21 will be described first with respect to the fully reclined position (

A drive link 168 is attached to the front ottoman drive link 108 at a pivot 172, and extends rearwardly therefrom to a pivot 170 with the frame mounting bracket 60.
Operation of the chair 10 typically begins in the upright position (
To move the chair 10 to the TV position of
The rearward movement of the seat 16 also drives the footrest linkage 150 to extend. As the seat 16 moves rearwardly, the drive link 168 rotates only slightly, with the net effect that the front ottoman drive link 108 rotates counterclockwise considerably about the pivot 110. This action also extends the rear ottoman extension link 112 and the auxiliary ottoman extension link 118, which in turn rotates the rear ottoman drive link 104 counterclockwise about the pivot 106. Once rotation of the rear ottoman drive link 104 causes the axis defined by the spring 105 to pass the pivot 106, the spring 105 then urges the rear ottoman drive link 104 toward the TV position.

In addition, the geometry of the auxiliary ottoman extension link 118, the auxiliary ottoman bracket 128, and the main ottoman extension link 134 allows a large main ottoman 20a to be employed. In a conventional footrest linkage that uses a single front ottoman extension bracket, the designer is faced with the issue of sufficient extension of the ottoman in front of the seat in order to provide a comfortable support surface for the feet of an occupant. However, with an ottoman such as that of the chair 10 that folds beneath the seat well off the underlying surface, not only must the main ottoman 20a be extended well forward of the seat 16 in order to provide a comfortable support surface for the occupant, the footrest linkage 150 must also unfold in such a way that the main ottoman 20a does not strike the underlying surface as it unfolds.
These functions are accomplished in the chair 10. As the rear and front ottoman drive links 104, 108 rotate and force the rear ottoman extension link 112 forward, the auxiliary ottoman extension link 118 also moves forward and rotates clockwise relative to the rear ottoman drive link 104 about the pivot 126. However, the use of the auxiliary ottoman extension link 118, the auxiliary ottoman bracket 128, and the main ottoman extension bracket 134 and the geometry of their pivot points causes the main ottoman 20a to rotate counterclockwise about the pivot 124 relatively slowly compared to the rotation of the front and rear ottoman drive links 108, 104. This reduced rotation of the main ottoman 20a enables the main ottoman 20a to be located well in front of the seat 16, with its upper edge raised slightly, before it rotates to a substantially vertical position (see
To be more specific, the front and rear ottoman drive links 108, 104 rotate counterclockwise approximately 120 degrees in moving from the upright to the TV position. This action drives the main ottoman 20a to rotate approximately 150 degrees. However, the front and rear ottoman drive links 108, 104 rotate about 70 degrees (more than half of their total rotation) in order to move the main ottoman 20a to the substantially vertical orientation of
In addition, the geometry of the auxiliary ottoman extension link 118, the auxiliary ottoman bracket 128, and the main ottoman extension link 134 permits the inclusion of the auxiliary ottoman 20b. Many recliners strive to avoid the presence of sizable gaps between the seat and any ottomans as a safety concern; generally speaking, gaps of greater than 5 inches by 5 inches are disfavored. This issue is typically addressed by the inclusion of one or more additional ottomans, such as the auxiliary ottoman 20b. However, such an ottoman must be able to retract into and extend from a position beneath the seat 16 that does not interfere with the movement of the reclining mechanism 21 or the detract from the appearance of the chair 10. The use of the auxiliary ottoman extension link 118, the auxiliary ottoman bracket 128, and the main ottoman extension link 134 allows the auxiliary ottoman 20a to reside between the seat 16 and the main ottoman 20b in the upright position, yet extend to a location in front of the seat 16 and rearward of the main ottoman 20b in the TV and upright positions.

The chair 10 can be returned to the TV and/or upright position by the occupant pushing downwardly with his feet on one or more of the ottomans 20a, 20b or pulling forwardly on the arms 29. The links of the reclining mechanism 21 will reverse the various movements described above.
Those skilled in this art will recognize that the reclining mechanism 21 may be employed with a variety of reclining seating units, including sofas and sectional units, including those that have fewer ottomans. Also, the reclining mechanism may be employed with seating units that actuate in different ways, such as handles, release levers, and the like.
The foregoing is illustrative of the present invention and is not to be construed as limiting thereof. Although exemplary embodiments of this invention have been described, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention.
