Recliners are generally well known in the furniture industry. The term recliner is used throughout this description to describe articles of furniture that include a reclining mechanism. Generally recliners are chairs that allow the user to recline and are equipped with extendable footrests. Recliners are often in the form of a plush chair, however, they might also take the form of an oversized seat, a seat-and-a-half, a love seat, a sofa, a sectional, and the like. Recliners are known in both a manual configuration (where the user releases the reclining mechanism from a closed position to a TV position, and moves the reclining mechanism from the TV position to a full recline position) and a motorized version (where a motor is used to move the mechanism between the various positions).
The reclining motion is achieved in recliners with a linkage mechanism that is coupled to a base. The linkage mechanisms found in recliners in the art include a plurality of interconnected links that provide one or more mechanisms for extending a footrest, reclining the recliner, and obstructing movements of the chair when in specific orientations. Typically, recliners known in the art provide three positions: an upright seated position with the footrest retracted beneath the chair (the “closed position”); a television viewing position in which the chair back is slightly reclined but still provides a generally upright position with the footrest extended (the “TV position”), and a full-recline position in which the chair back is reclined an additional amount farther than in the TV position but still generally inclined with respect to the seat of the chair and with the footrest extended (the “fully reclined position”).
These types of prior art recliner mechanisms, while functional, suffer from a number of drawbacks. One of which includes a problem known as shirt pull. Shirt pull occurs as the user reclines the back of the chair, and the chair back rotates back, but also away from the seat, increasing the distance between the bottom of the back cushion and the back of the seat cushion. This movement not only results in shirt pull, but also removes support from the lower lumbar area of the user seated in the chair. In some cases, a gap may form between the seat cushion and the back cushion resulting in discomfort to the user seated in the chair. This motion is caused by a back bracket pivot point that is typically below and behind the point where the chair back cushion and the seat cushion meet. It would be desirable to provide a recliner, whether manual or motorized, having a back pivot point projected to as close as possible to the point at which the bottom of the back cushion and the back of the seat cushion meet.
Further, recliners typically move forward when changing from the closed position to the TV position, and from the TV position to the fully reclined position to accommodate the reclining of the back and the shifting of the center of gravity of the recliner and the user seated therein. Moreover, in order to provide as much wall clearance as possible, recliners have moved forward as much as possible. Recliners known in the art have a minimum wall clearance of 4.5 inches in order to fully move between the closed position, the TV position, and the fully reclined position. The amount of wall clearance is limited principally by two factors, the angle relative to a base rail of front and rear pivot links in the closed position and the arcs about which they may travel and the length of the front and back pivot links. In the closed position, known pivot links are set at an angle just forward of normal to the base rail. This allows gravity to assist the user of the chair to move from the closed position to the TV position. It would be desirable to provide a recliner having a wall clearance less than 4.5 inches, and as small as possible, to allow the user as much freedom as possible when positioning the recliner in a room.
Embodiments of the invention are defined by the claims below, not this summary. A high-level overview of various aspects of the invention are provided here for that reason, to provide an overview of the disclosure, and to introduce a selection of concepts that are further described below in the detailed-description section. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in isolation to determine the scope of the claimed subject matter.
In an embodiment of the invention a linkage for use in reclining furniture is described. The linkage includes a back bracket supported by forward and rear back pivot links. The bottom of the rear back pivot link is pivotally coupled to a rear lift link, and the bottom of the forward back pivot link is pivotally coupled to a seat mounting plate, and the rear lift link is pivotally coupled to the seat mounting plate at a different location. A control link is pivotally coupled on one end to the seat mounting plate and on the other end to an intermediate point on the rear back pivot link. The control link operates to pull the pivoting linkage of the back bracket, and the forward and rear back pivot links as the overall linkage is moved from the closed position, to the TV position, and to the full recline position. The resulting pivot point for the back of the recliner is projected upwardly and forwardly, to a point where an upholstered back and seat meet on a finished chair, resulting in far less shirt pull than in previously known mechanisms and chairs. During recline, the bottom of the back of the chair will follow the user, offering full support of the user's back and avoid the undesirable gap between cushions, even in the full-recline position.
The back bracket rotating about the projected pivot point in the linkage described above allows for a decreased minimum wall clearance than in previously known mechanisms and chairs. When the recliner moves from the closed position to the TV position, and from the TV position to the fully reclined position, the back bracket moves forward allowing the back of the chair to recline while providing additional clearance. In other words, the forward movement associated with the projected pivot point allows the recliner to be placed closer to the wall than previously known mechanisms and chairs.
In another embodiment, the linkage is supported above a base rail by front and rear pivot links. In a motorized version, the rear pivot link may be set at an angle behind normal to the base rail, which provides a longer arc for the rear pivot link to travel. Hence, in addition to the additional forward movement due to the projected pivot point disclosed above, the motorized version may include even more forward movement due to the longer arc of travel for the rear pivot link. This embodiment can eliminate wall clearance for the recliner entirely and the recliner can be placed adjacent a wall and still move between the closed position and the fully reclined position without contacting the wall.
Illustrative embodiments of the invention are described in detail below with reference to the attached drawing figures, and wherein:

Some aspects of this disclosure have been described with respect to the illustrative examples provided by
One aspect disclosed herein is directed to a linkage mechanism including a seat mounting plate for mounting a recliner seat thereon, a back bracket for mounting a recliner back portion thereon and an intermediate link between the seat mounting plate and the back bracket. The seat mounting plate may have a first pivot point. The intermediate link may have a first end opposite a second end. The first end of the intermediate link may be pivotally connected to the seat mounting plate at the first pivot point. The back bracket may have a forward pivot point. The second end of the intermediate link may be pivotally connected to the back bracket at the forward pivot link. Upon forward motion of the seat mounting plate as the linkage mechanism unfolds from a closed position the forward pivot point may be moved forwardly and downwardly.
In some aspects, the linkage mechanism may also include a back support link having a back support link first end opposite a back support link second end. The back support link first end may be pivotally connected to the back bracket at a rear pivot point. The rear pivot point may be rearward of the forward pivot point. The back support link second end may be pivotally connected to a rear lift link rearward of a pivotal connection between the rear lift link and the seat mounting plate.
In other aspects the linkage mechanism may also include a back control link. The back control link may have a back control link first end opposite a back control link second end. The back control link first end may be pivotally connected to the back support link intermediate to the back support link first end and the back support link second end. The back control link second end may be pivotally connected to the seat mounting plate at a second pivot point. The second pivot point may be positioned rearward on the seat mounting plate from the first pivot point.
The linkage mechanism may be configured to move between the closed position and a fully reclined position. Whereupon movement of the linkage mechanism from the closed position to the fully reclined position the forward pivot point of the back bracket may be moved forwardly and upwardly. Whereupon movement of the linkage mechanism from the closed position to the fully reclined position the rear pivot point of the back bracket may be moved forwardly and downwardly. In other aspects, whereupon movement of the linkage mechanism from the closed position to the fully reclined position the back bracket may rotate around a projected pivot point. The projected pivot point may be forward and above the forward pivot point of the back bracket when the linkage mechanism is in the closed position. The projected pivot point may be rearward and above the forward pivot point of the back bracket when the linkage mechanism is in the fully reclined position.
In some aspects, the linkage mechanism is configured to stop at a TV position intermediate to the closed position and the fully reclined position. The linkage mechanism may also include a motor coupled to the linkage mechanism. The motor may be configured to move the linkage mechanism between the closed position and the fully reclined position. In other aspects, the linkage mechanism is configured to be manually moved between the closed position and the fully reclined position.
Another aspect disclosed herein is directed to a reclining seating unit requiring reduced wall clearance. The reclining seating unit may include a linkage mechanism having a seat mounting plate, a back bracket indirectly coupled to the seat mounting plate. The back bracket may be configured to move forward relative to the seat mounting plate as the seating unit moves from a closed position towards a fully reclined position. The reclining seating unit may also include a finished seat back coupled to the back bracket. The finished seat back may have a trailing edge comprising the rearwardmost edge of the reclining seating unit. The reclining seating unit may be configured to require between 0 inches and 4.5 inches of clearance rearward of the trailing edge when the reclining seating unit is in the closed position in order to for the seating unit to move unobstructed to the fully reclined position.
In other aspects, the reclining seating unit may also include an intermediate link that indirectly couples the back bracket to the seat mounting plate. The intermediate link may have a first end opposite a second end. The first end of the intermediate link may be pivotally connected to the seat mounting plate at a first pivot point. The second end of the intermediate link may be pivotally connected to the back bracket at a second pivot point.
The reclining seating unit may be configured to be manually moved between the closed position and the fully reclined position. Said reclining seating unit may require between 2 inches and 4.5 inches of clearance rearward of the trailing edge when the reclining seating unit is in the closed position in order for the reclining seating unit to move unobstructed to the fully reclined position. The reclining seating unit may also include a motor coupled to the linkage mechanism. The motor may be configured to move the reclining seating unit between the closed position and the fully reclined position.
Another aspect disclosed herein is directed to a motor-driven linkage mechanism. The motor-driven linkage mechanism may be configured to move between a closed position and a fully reclined position. A motor may be coupled to the linkage mechanism and configured to move the linkage mechanism between the closed position and the fully reclined position. A base rail having a forward end opposite a rearward end may be positioned beneath the linkage mechanism. A rear pivot link may be pivotally connected to the base rail at a first pivot point and pivotally connected to the linkage mechanism at a second pivot point. An angle between the base rail and a line extending from the first pivot point to the second pivot point may be an obtuse angle when the linkage mechanism is in the closed position.
The motor-driven linkage mechanism may also include a forward pivot link pivotally connected to the base rail at a third pivot point and pivotally connected to the linkage mechanism at a fourth pivot point, in accordance with some aspects. A second angle between the base rail and a line extending from the third pivot point to the fourth pivot point may be an obtuse angle when the linkage mechanism is in the closed position.
The angle between the base rail and the line extending from the first pivot point to the second pivot point may be an acute angle when the linkage mechanism is in the fully reclined position. The first pivot point may be forward of the second pivot point when the linkage mechanism is in the closed position.
