FIELD OF THE INVENTION
The present invention relates generally to a chair or seat for theater or auditorium seating and, more particularly, to a reclining chair at a stepped riser support.
BACKGROUND OF THE INVENTION
It is known to provide a recliner chair at a riser support, such as at a theater or auditorium. Examples of chairs or systems on a stepped riser and/or sloped support surface are described in U.S. Pat. Nos. 10,888,162 and 10,507,742.
SUMMARY OF THE INVENTION
The present invention provides a recliner chair positioned on a base, such as a stepped riser support, with the seat of the chair disposed at or along the horizontal portion or face of the stepped riser support and the footrest or ottoman of the chair disposed (when lowered) at or along the vertical portion or face of the stepped riser support. The recliner chair includes an actuator that, when electrically operated to recline the chair, raises the ottoman upward and outward from the vertical portion of the stepped riser support and/or tilts the seat and the seat back toward a reclined position. The ottoman is raised and the seat and seat back are tilted or reclined via a single actuator.
The actuator may be disposed along an arm rest or side portion of the recliner chair and connected to a linkage or reclining mechanism at the ottoman, whereby movement of the ottoman by the actuator may impart movement of the seat and seat back. Optionally, the actuator may be connected to a linkage or reclining mechanism that connects to a frame of the seat, whereby movement of the seat frame (and thus the seat and the seat back) by the actuator imparts movement of the ottoman. The actuator is disposed along and within the arm rest or side portion of the recliner chair such that the area of the horizontal portion of the stepped riser support beneath the seat is devoid of the actuator and mechanisms, which allows for easier cleaning of the recliner chair and stepped riser support.
These and other objects, advantages, purposes and features of the present invention will become apparent upon review of the following specification in conjunction with the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings and the illustrative embodiments depicted therein, an individual recliner chair 10 may be part of a stadium or theater or auditorium seating configuration, which comprises a plurality of chairs arranged in rows (although only one chair is shown in FIG. 1). The individual recliner chairs of the seating configuration may be arranged one next to another at a stepped riser support structure 12 (FIG. 19), with an arm rest 14 at each side of the chair 10. Optionally, each arm rest 14 between adjacent chairs of the row of chairs may be shared by the adjacent chairs. The chair 10 includes a seat or seat portion 16, a seat back 18 and an ottoman 20, with an arm rest 14 at each side of the seat portion 16. The chair 10 includes an actuator 22 and reclining mechanism 24 (FIGS. 4-17) that function to move the ottoman 20 relative to the seat portion 16 and to tilt the seat portion 16 and seat back 18 relative to the support structure 12 to move the chair between an upright or non-reclined seating position or state (FIG. 2) and a reclined seating position or state (FIGS. 1 and 3).
As shown in FIGS. 4-18, the reclining mechanism 24 includes a mounting frame 26 that has rearward brackets 26a and forward brackets 26b that mount to the horizontal portion of the support structure 12 and/or to brackets of adjacent chairs 10 (such as via threaded fasteners or the like). The mounting frame 26 may include rails or plates that extend along opposing sides of the chair 10. A rotatable shaft 28 is rotatably mounted at the frame 26 at a forward portion of the frame 26 and extends across the forward portion of the frame (and rotatably mounts at opposite side portions of the frame). In the illustrated example, the shaft 28 is rotatably mounted between the forward brackets 26b. A seat and seat back frame 30 (including a seat frame portion 30a to which the seat attaches and a seat back frame portion 30b to which the seat back attaches) is mounted at the frame 26 and pivotable relative to the riser 12 with the frame 26. For example, and such as shown in FIGS. 12 and 15, the frame 26 may be pivotally mounted relative to the rearward brackets 26a at a pivot pin 31 at each side of the frame 26. The seat and seat back frame 30 supports the seat portion 16 and the seat back 18 at the frame 26 (FIGS. 7 and 8). The seat frame portion 30a may include a pair of brackets at the forward portion of the frame 26 and the seat back frame portion 30b may include a pair of supports at a rearward portion of the frame 26.
The ottoman 20 is attached at an ottoman bracket 20a that is pivotally mounted at the forward portion of the frame 26. In the illustrated example, the ottoman bracket 20a is attached to a pair of mounting arms 32 at opposing sides of the ottoman bracket 20a (FIG. 17). A pair of scissor linkages 40 pivotally attach the mounting arms 32 to the forward portion of the frame 26 (FIGS. 12-15). As discussed further below, a pair of first pivot links 34 and a pair of second pivot links 36 are pivotally connected between the rotating shaft 28 and the forward portion of the frame 26 for tilting the frame 26 (i.e., about the pivot pin 31) and extending and retracting the pair of scissor linkages 40 (FIGS. 8-11). Tilting the frame 26 causes the seat portion 16 and the seat back 18 to pivot or tilt relative to the riser 12. Extending the scissor linkages 40 causes the ottoman 20 to extend and pivot relative to the frame 26 and the seat portion 16.
As shown in FIGS. 4-11, the actuator 22 may be disposed within or below one of the arm rests 14 and comprises a linear actuator (e.g., a screw-drive actuator that rotates a shaft to move a drive element along the shaft in either direction, or a hydraulic actuator that extends and retracts a piston and rod responsive to pressurized fluid at one or both ends of a hydraulic cylinder) that connects to a pivoting link 38 that is fixedly attached (such as via welding or other non-rotational attachment) at the shaft 28 of the reclining mechanism 24. When the chair 10 is in an upright or non-lowered position (e.g., FIG. 2), the ottoman 20 is retracted toward the riser 12 and the seat back 18 is substantially upright or vertical relative to the horizontal seat portion 16 to position a user in a generally upright seated position, while the actuator 22 may be in an extended position. To move the chair 10 from the upright position toward a reclined position (e.g., FIGS. 1 and 3), where the ottoman 20 is extended from the riser 12 to support the user's legs and/or feet and the seat back 18 is tilted back toward a horizontal position to position the user in a reclined or laying position, the actuator 22 may be retracted to pull on the pivoting link 38.
Referring to FIGS. 8-15, pulling on the pivoting link 38 to move the chair 10 from the upright position toward the reclined position causes the shaft 28 to rotate. The first pivot links 34 are non-pivotally attached to the shaft 28 (such as via welding or other non-rotational attachment) and pivotally attached to the second pivot links 36. The second pivot links 36 are pivotally attached to the forward portion of the frame 26. As rotation of the shaft 28 rotates the first pivot links 34, the first pivot links 34 and the second pivot links 36 cause the frame 26 to pivot about the pivot link 31 thus raising the forward portion of the frame 26 relative to the riser 12. This causes the seat portion 16 and the seat back 18 to tilt or recline together and in tandem. The seat portion 16 and the seat back 18 may pivot relative to the riser 12 by any suitable degree, such as by 5 degrees or more, 10 degrees or more, 15 degrees or more, and the like.
First ends of the scissor linkages 40 are attached to the mounting arms 32 and second ends of the scissor linkages 40 are constrained to the riser 12 (e.g., via attachment at the forward bracket 26b). Thus, as the forward portion of the frame 26 raises relative to the riser 12, the scissor linkages 40 are pivoted relative to the frame 26 to pivot and extend the ottoman 20 relative to the seat portion 16. That is, the ottoman bracket 20a is pinned or constrained at the same height as the pivot pin 31 to cause substantially simultaneous movement of the ottoman 20 during tilting of the seat portion 16 and seat back 18.
In the illustrated example, the scissor linkages 40 include a connecting link 41 that is pivotally attached to the forward bracket 26b and pivotally attached to a first end of an L-shaped link 42. An opposing second end of the L-shaped link 42 is pivotally attached to a lower link 43 and an upper link 44 that are pivotally attached to the mounting arms 32. A central portion of the L-shaped link 42 between the first end and the second end may be constrained relative to the forward portion of the frame 26. A link 45 may pivotally attach at a first end of the forward portion of the frame 26 and pivotally attach at an opposing second end to the upper link 44. Thus, as the forward portion of the frame 26 raises relative to the riser 26, the first end of the L-shaped link 42 is constrained by the connecting link 41 which causes the L-shaped link 42 to pivot. As the second end of the L-shaped link 42 pivots away from the frame 26, connection between the link 45 and the upper link 44 causes the upper link 44 and the lower link 43 to pivot relative to the L-shaped link 42 and extend the ottoman 20 relative to the seat portion 16.
Thus, with the chair 10 in the upright position and when the actuator 22 is operated to pull at the end of the pivoting link 38, the seat portion 16 and the seat back 18 may tilt or pivot relative to the riser 12 and the ottoman 20 may pivot upward and extend relative to the riser 12 substantially together and in tandem with one another to move the chair 10 toward the reclined position. Similarly, with the chair 10 in the reclined position, the actuator 22 may be operated to retract the ottoman 20 and tilt the seat portion 16 and the seat back 18 back toward the upright position substantially together and in tandem. The actuator 22 and reclining mechanism 24 may function to move the ottoman 20 and the seat portion 16 and the seat back 18 between the upright position and the reclined position via a single actuation of the actuator 22. For example, the user may control operation of the actuator 22 via a switch or button or input 46 at the arm rest 14, where a first press and hold of the button 46 may move the chair 10 from the upright position toward the reclined position and releasing the button 46 may hold the chair 10 in a desired position between the upright position and the reclined position, and a second press and hold of the button 46 may move the chair toward the upright position (FIG. 1).
Optionally, the ottoman 20 and/or the ottoman bracket 20a may be mounted to the mounting arms 32 via a spring-loaded or flexible mounting plate 32a (FIG. 17). That is, the flexible mounting plate 32a may be attached at the ottoman bracket 20a and pivotable relative to the mounting arms 32 to accommodate forces experienced at the ottoman 20 and/or the ottoman bracket 20a. Optionally, the flexible mounting plate 32a is attached at the mounting arms 32 and pivotable relative to the ottoman bracket 20a. For example, if a lower portion of the ottoman 20 catches on an obstruction while the ottoman 20 is being retracted, the ottoman 20 pivots in a first direction relative to the mounting arms 32. If an upper portion of the ottoman 20 catches on the obstruction while the ottoman 20 is being retracted, the ottoman 20 pivots in an opposite second direction relative to the mounting arms 32. The flexible mounting plate 32a may move partially away from the mounting arms 32 when pivoted and the flexible mounting plate 32a may be biased toward engagement with the mounting arms 32 (e.g., via a coil spring or other biasing member) to maintain the ottoman 20 and ottoman bracket 20a against the mounting arm 32 when no obstruction is present.
As shown in FIGS. 4-7, the actuator 22 is accommodated within the arm rest 14 along one side of the chair 10, with the pivoting link 38 non-rotatably attached at an end of the shaft 28. This allows a region or space 48 beneath the seat portion 16 to be generally empty or devoid of obstructions. That is, the region 48 between the upper surface of the riser 12 and the seat portion 16 is devoid of any portion of the actuator 22 or structural support of the chair 10 and may be easily accessed when the chair 10 is moved to the reclined position, such as for cleaning of the riser 12. The region 48 may be bound by the upper surface of the riser 12, the lower surface of the seat portion 16, the frame 26 extending along opposing sides of the chair 10 and the seat back frame portion 30b at the rearward portion of the frame 26.
Moreover, the actuator 22 may be attachable and detachable as a separate unit from the chair 10 to allow for easier installation and maintenance. For example, the actuator 22 includes a mounting bracket or plate or rail 50 that attaches (e.g., via threaded fasteners or other suitable attachment means) to the rearward bracket 26a and the forward bracket 26b along one side of the chair 10. The pivoting link 38 includes a coupling portion 39 that fixedly attaches to the end of the shaft 28 and the pivoting link 38 is rotated via extension and retraction of an arm 52 of the actuator 22. The arm 52 is extended and retracted relative to a housing 54 (e.g., that accommodates a motor or hydraulic cylinder). To accommodate vertical movement of the arm 52 and pivoting link 38 as the pivoting link 38 pivots the shaft 28, the housing 54 is pivotally mounted to the mounting rail 50 via a pivot pin 56. That is, as the arm 52 extends and retracts relative to the housing 54 to pivot the pivoting link 38, the arm 52 and housing 54 may pivot relative to the mounting rail 50 about the pivot pin 56 to accommodate the rotation of the pivoting link 38.
The rearward brackets 26a may include slots to allow the frame 26 and the actuator 22 to be mounted at an angle relative to one another (FIG. 16). In other words, the chair 10 and the actuator 22 may be pivoted relative to one another (e.g., about the mounting point at the forward bracket 26a) via movement of the mounting rail 50 relative to the rearward bracket 26a as accommodated by movement of fasteners extending through the slots at the rearward bracket 26a. Moreover, the brackets 26a, 26b may attach between the frame 26 of one chair and the mounting rail 50 of the actuator 22 of an adjacent chair (e.g., FIG. 18). This allows for adjacent chairs 10 to be mounted at the risers 12 and angled relative to one another, such as at angles of 1 degree or more, 2.5 degrees or more, 5 degrees or more, and the like to form a radius of chairs. A pin attaching the end of the actuator arm 52 and the pivoting link 38 may provide clearance to accommodate the shaft 28 and/or pivoting link 38 being disposed at an angle relative to the arm 52.
As shown in FIGS. 4-6, the arm rest 14 provides a casing for the actuator 22 that attaches to the mounting rail 50. That is, the arm rest 14 includes an open end and recess or cavity that accommodates the actuator 22. To attach the arm rest 14 at the actuator 22, a rearward portion of the arm rest 14 is slidingly engaged with the mounting rail 50 so that a rear lip or tab 50a of the mounting rail 50 engages a rear inner lip 14a of the arm rest 14. The forward portion of the arm rest 14 is then lowered toward the riser 12 and a front inner lip 14b of the arm rest 14 is attached to a front lip or tab 50b of the mounting rail 50, such as via a threaded fastener or other attachment means. Thus, the rear tab 50a holds the rear inner lip 14a of the arm rest between the tab 50a and the riser 12 and the front inner lip 14b is secured to the front tab 50b. This secures the arm rest 14 relative to the actuator 22 and the chair 10 with as few as one fastener, and the arm rest 14 is readily pivoted relative to the rear tab 50a and/or removed from the mounting rail 50 to provide access to the actuator 22.
The actuator 22 and chair 10 may thus be mounted to a variety of different base structures, such as the riser 12 or a standalone base having individual legs. The side-mounted actuator 22 and reclining mechanism 24 allow the chair 10 (or optionally a plurality of chairs in a row) to be moved to the reclining position for obstruction-free access to the regions 48 beneath the seats. Moreover, the chairs 10 may be mounted at oblique angles (e.g., up to 5 degrees or more) relative to one another and/or relative to their associated actuator 22 for arranging rows of chairs in radiused or semi-circular arrangements. The actuator 22 is mountable to the chair 10 as a unit and the arm rest 14 provides a cover or casing that removably attaches to the actuator. The actuator 22 may be coupled to chairs having any suitable reclining mechanism actuated by rotation of a shaft.
Although shown and described as having a linear actuator that moves an end of a pivoting link to pivot a shaft of the reclining mechanism to move the ottoman and seat and seat back, it is envisioned that the actuator may directly rotatably drive the shaft to rotate the shaft in either direction. For example, the actuator may comprise a rotationally driving actuator that drives an output shaft that is linked (either directly connected or keyed or indirectly connected via a gear train or drive belt) to the horizontal shaft.
Optionally, with the chair in the upright position, the actuator and the reclining mechanism may function to initially extend the ottoman and then, with the ottoman extended, tilt or pivot the seat portion and the seat back toward the reclined position. For example, a chair 110 is mounted to a horizontal support surface of the riser 12 (FIG. 19). The chair 110 includes a seat or seat portion 116, a seat back 118 and an ottoman 120, with an arm rest 114 at each side of the seat portion 116. The chair 110 includes an actuator 122 and reclining mechanism 124 (FIGS. 22-31) that function to move the ottoman 120 relative to the seat portion 116 and to tilt the seat portion 116 and seat back 118 relative to the support structure 112 to move the chair between an upright or non-reclined seating position or state (FIG. 20) and a reclined seating position or state (FIGS. 19 and 21).
The reclining mechanism 124 includes a mounting frame 126 that has brackets 126a that mount to the horizontal portion of the support structure 12 (such as via threaded fasteners or the like). A rotatable shaft 128 is rotatably mounted at the frame 126 at a forward portion of the frame 126 and extends across the forward portion of the frame (and rotatably mounts at opposite side portions of the frame). A seat and seat back frame 130 (including a seat frame portion 130a to which the seat attaches and a seat back frame portion 130b to which the seat back attaches) is pivotally mounted at a rearward portion of the frame 126. For example, and such as shown in FIG. 28, the frame 126 may be pivotally mounted at a pivot pin 131 at each side of the frame 126.
The ottoman 120 is attached at an ottoman bracket 120a that is pivotally mounted at a forward portion of the seat and seat back frame 130 via mounting arms 132 that are linked to the rotatable shaft 128 via a pair of pivot links 134, 136. The mounting arms 132 are fixedly or non-pivotally attached at the ottoman bracket 120a and pivotally attached at opposite side regions of the seat frame 130a, while the pivot links 134 are non-pivotally attached at the shaft 128 (such as via welding or other non-rotational attachment) and pivotally attached to the respective links 136, which in turn are pivotally attached at the ottoman bracket 120a or at the mounting arms 132.
When the actuator is actuated to pull at the end of a pivoting link 138 (via linear or translational movement of a connecting portion of the actuator that connects to the end of the pivoting link), the pivoting link 138 pivots and rotates the horizontal shaft 128, which in turn pivots the first pivot links 134 to pivot the ottoman outward and upward (see, for example, FIGS. 22-25 and 27). As the first pivot links 134 pivot, the second pivot links 136 also pivot to extend the ottoman, which pivots relative to the frame 130 via the mounting arms 132. When initially pivoted (when the actuator is actuated to begin reclining the chair from the non-reclined position of FIG. 26), the ottoman pivots relative to the seat and seat back frame 130 (via pivoting of the mounting arms 132 relative to the seat and seat back frame 130) and the seat and seat back frame 130 (and thus the seat 116 and seat back 118) does not pivot or move relative to the frame 126 and the support structure 12 (see FIG. 27). This allows the person sitting in the chair to raise the ottoman without reclining the seat or seat back.
When the ottoman is raised a threshold amount, the mounting arms 132 contact a stop at the seat and seat back frame 130 (e.g., the mounting arms 132 may be formed at an angle such that a portion of the mounting arms 132 near the pivot attachment engages a flange or surface of the seat and seat back frame) to limit further pivotal movement of the mounting arms 132 and the ottoman relative to the seat and seat back frame 130. Further rotation of the shaft 128 (by further actuation of the actuator) causes the ottoman to raise further and to raise the forward end of the seat and seat back frame 130 upward. Such upward movement of the forward end of the seat and seat back frame 130 pivots the seat and seat back frame 130 (and the seat and seat back) about the pivot pin 131 at the rearward portion of the frame 126 to recline the chair.
Thus, the actuator and reclining mechanism function to move the ottoman and seat and seat back from a non-reclined position (where the ottoman is lowered to be along the vertical surface or portion of the riser support structure) to a reclined position (where the ottoman is raised and the seat is tilted upward and the seat back is tilted rearward), with a single actuation of the actuator (e.g., the user pushes one button and holds that one button until the ottoman and seat are in the desired position). The actuator is located at and along the side of the seat (e.g., in the arm rest structure) and thus the area immediately beneath the seat is devoid of any actuator components and reclining mechanism components. Thus, the chair and support structure can be easily cleaned by tilting up the seat or removing the seat (see, for example, FIGS. 30 and 31).
Optionally, the actuator may operate to pivot the seat and seat back along with the ottoman as the actuator is actuated to recline the chair from the fully non-reclined position. For example, and such as shown in FIGS. 32-41, the reclining mechanism 224 may have a pair of links 240, 241 (FIG. 34) that connect a forward portion of the seat and seat back frame 230 to the horizontal shaft 228 rotatably mounted at the base frame 226 (with the links 240 fixedly or non-rotationally attached at the shaft), such that rotation of the shaft 228 (rotated via actuation of the actuator) pivots the links 240 and moves the forward portion of the frame 230 (e.g., pivots the frame 230 about a pivot axis at a pivot pin or location 231 at or near or forward of the seat back bracket 230b. As the forward portion of the frame is raised/tilted, a scissor-linkage 242 that attaches the ottoman bracket 220a to the forward portion of the frame 230 extends to extend the ottoman. The scissor-linkage 242 includes two links that are pivotally attached at spaced apart portions of the forward portion of the frame 230, with one of those links 242a being connected to a link 243 (FIG. 34) that is pivotally attached at the frame 226. Link 242a is a generally L-shaped link that is pivotally attached at the frame 230 and at the distal end of the link 243 (distal from the frame 226), such that movement of the end of the L-shaped link 242a causes the link to pivot relative to the frame 230, which causes pivoting and extending/retracting of the ottoman. Thus, the ottoman extends as the frame 230 is tilted and raised toward the reclined state (FIG. 34), as the link 243 limits upward movement of the end of the L-shaped link 242a and causes the L-shaped link 242a to pivot, and the ottoman retracts as the frame is lowered toward the closed or non-reclined state (FIG. 32).
As shown in FIGS. 38-41, the actuator 222 is disposed within an arm rest casing 214a of the arm rest of the recliner chair. The actuator 222 mounts to the base frame 226 and within the arm rest casing 214a and has an end 222a connected to the pivot link 238 that is fixedly attached (such as via welding or other non-rotational attachment) at the shaft 228. As can be seen with reference to FIGS. 40 and 41, the pivot link 238 may include a coupling portion 239 that couples to the end of the shaft 228 and is non-rotatably attached at the end of the shaft, such that pivoting of the link 238 pivots or rotates the coupling portion 239 and the shaft 228, which imparts pivotal movement of the link 240 to raise the front end of the frame 230 and to pivot the link 242a of the scissor mechanism 242.
Optionally, and such as shown in FIGS. 42-44, the actuator may rotate the shaft 328 (that is rotatably mounted at a forward portion of a base frame 326) of a reclining mechanism 324 to raise the forward portion of the seat and seat back frame 330 while also pivoting/extending the ottoman as the actuator operates to adjust the chair from the non-reclined position (FIG. 42) toward the fully reclined position (FIG. 44). As shown in FIGS. 43 and 44, the ottoman is pivoted and extended responsive to a linkage or pair of links 342, 343 that connect to the footplate or ottoman bracket and that pivot the ottoman as the seat and seat back are reclined. In the illustrated embodiment, the link 342 is pivotally attached at the base frame 326 and the link or mounting arm 343 pivotally joins the other end of the link 342 with the ottoman bracket 320a. The mounting arm or link 343 is a generally L-shaped arm or link that is pivotally mounted at the bracket 330 (such as in a similar manner as link 242a, discussed above). As the forward portion of the frame is raised/tilted via a pair of links 344, 345 that connect the frame 330 to the shaft 328 (with links 344 fixedly attached at the shaft 328), the link 342 pivots and limits upward movement of the end of the mounting arm 343, which causes the mounting arm 343 to pivot relative to the frame 330 and thus to extend and pivot the ottoman bracket 320a relative to the frame 330 to extend the ottoman. Thus, the ottoman extends as the frame 330 is tilted and raised toward the reclined state (FIG. 44) and the ottoman retracts as the frame is lowered toward the closed or non-reclined state (FIG. 42).
Thus, the recliner chair provides pivoting movement of the seat and the seat back and the ottoman via rotational driving of a horizontal shaft at a forward portion of the base frame, with the reclining mechanism comprising a plurality of pivoting linkages or arms that impart the desired movement of the ottoman and seat and seat back when the actuator is actuated to recline or lower the chair. The reclining mechanism is disposed at the side regions of the ottoman and frame, and the actuator is disposed at the arm rest structure or other structure at a side region of the chair, such that the regions of the support surface beneath the seat portion and behind the ottoman is substantially clear or devoid of actuator components and/or reclining mechanism components, with the frame and the horizontal drive shaft being about the only components at those regions.
Optionally, in some implementations, the actuator may be disposed at the support structure, such as at the vertical portion or face of the support structure, and may operate to push the ottoman outward and upward away from the vertical face of the support structure. For example, and such as shown in FIGS. 45 and 46, the actuator 422 may extend and retract to raise and lower the ottoman, and linkages that connect the ottoman 420 to the seat and seat back frame pivot to raise and tilt the seat 416 and seat back 418 as the ottoman is raised.
Optionally, the actuator may be disposed at the horizontal portion or face of the support structure, and may operate to push or pull the seat back to pivot the seat back between the upright and reclined positions. For example, and such as shown in FIGS. 47 and 48, the actuator 522 may extend and retract to raise and lower the seat back 518, and linkages that connect the seat and seat back frame to the ottoman 520 pivot to raise and tilt the ottoman as the seat and seat back are adjusted.
Therefore, the recliner chair over riser structure has a single actuator for raising the ottoman and correspondingly tilting/reclining the seat and seat back. The actuator and reclining mechanism are arranged at the chair and support structure remote from the area or region immediately under the seat and/or behind the ottoman, such that cleaning of the chair and support structure is enhanced. The chair may simply be reclined or partially reclined (or the seat portion may be lifted or removed) to provide access to the support structure under the chair, with the support structure in that area being substantially devoid of components of the actuator and/or reclining mechanism.
Changes and modifications in the specifically described embodiments can be carried out without departing from the principles of the invention, which is intended to be limited only by the scope of the appended claims, as interpreted according to the principles of patent law including the doctrine of equivalents.
