Reclining seating unit for use in theater with riser arrangement

Abstract

A seating unit includes: a frame having a pair of arms, wherein each of the arms includes a cutaway portion in a lower rear area thereof, the cutaway portion configured to receive a tread and a riser of a riser arrangement; a backrest; a seat; a first footrest; a reclining mechanism; and a linear actuator. The reclining mechanism is connected between the backrest, seat, and first footrest, the reclining mechanism comprising a series of pivotally interconnected links and configured to move the seating unit between: (a) an upright position, in which the backrest is disposed at a first generally upright backrest angle relative to the seat, the seat is disposed at a first generally horizontal seat angle and at a first longitudinal position, and the first footrest is retracted below a forward portion of the seat; and (b) a fully reclined position, in which the backrest is disposed at a second backrest angle relative to horizontal that is shallower than the first backrest angle, the first footrest is extended in front of the seat, the seat has a second seat angle that is deeper relative to horizontal than the first seat angle, and the seat has a second longitudinal position that is rearward of the first longitudinal position. The reclining mechanism includes a footrest mechanism attached to the first footrest, the footrest mechanism configured to control relative movement of the first footrest relative to the seat. The linear actuator is attached to the reclining mechanism and the footrest linkage and configured to move the backrest, seat and first footrest between the upright and fully reclined positions. The linear actuator and the footrest linkage reside entirely below a front portion of the seat and in front of the cutaway portion of the arms.

What is claimed is: 
     
         1 . A reclining seating unit, comprising:
 a frame having a pair of arms, wherein each of the arms includes a cutaway portion in a lower rear area thereof, the cutaway portion configured to receive a tread and a riser of a riser arrangement;   a backrest;   a seat;   a first footrest;   a reclining mechanism connected between the backrest, seat, and first footrest, the reclining mechanism comprising a series of pivotally interconnected links and configured to move the seating unit between: (a) an upright position, in which the backrest is disposed at a first generally upright backrest angle relative to the seat, the seat is disposed at a first generally horizontal seat angle and at a first longitudinal position, and the first footrest is retracted below a forward portion of the seat; and (b) a fully reclined position, in which the backrest is disposed at a second backrest angle relative to horizontal that is shallower than the first backrest angle, the first footrest is extended in front of the seat, the seat has a second seat angle that is deeper relative to horizontal than the first seat angle, and the seat has a second longitudinal position that is rearward of the first longitudinal position;   wherein the reclining mechanism includes a footrest mechanism attached to the first footrest, the footrest mechanism configured to control relative movement of the first footrest relative to the seat;   a linear actuator attached to the reclining mechanism and the footrest linkage and configured to move the backrest, seat and first footrest between the upright and fully reclined positions;   wherein the linear actuator and the footrest linkage reside entirely below a front portion of the seat and in front of the cutaway portion of the arms.   
     
     
         2 . The seating unit defined in  claim 1 , wherein the cutaway portion is defined by a front edge and an upper edge, and wherein the front edge is substantially perpendicular to the upper edge. 
     
     
         3 . The seating unit defined in  claim 1 , wherein the linear actuator includes a rail, and wherein the rail is disposed at an angle of at least 30 degrees in the upright position. 
     
     
         4 . The seating unit defined in  claim 1 , further comprising a second footrest, wherein in the upright position, the second footrest is generally vertically disposed and rearward of the first footrest, and in the fully reclined position the second footrest is generally horizontally disposed and forward of the first footrest. 
     
     
         5 . The seating unit defined in  claim 1 , wherein the reclining mechanism further includes a carrier link that is fixed relative to the seat, and wherein the linear actuator is pivotally attached to a lower forward end portion of the carrier link. 
     
     
         6 . The seating unit defined in  claim 5 , wherein the backrest is fixed to a backpost, and wherein the carrier link is pivotally connected to the backpost. 
     
     
         7 . A reclining seating unit, comprising:
 a frame having a pair of arms;   a backrest;   a seat;   a first footrest;   a reclining mechanism connected between the backrest, seat, and first footrest, the reclining mechanism comprising a series of pivotally interconnected links and configured to move the seating unit between: (a) an upright position, in which the backrest is disposed at a first generally upright backrest angle relative to the seat, the seat is disposed at a first generally horizontal seat angle and at a first longitudinal position, and the first footrest is retracted below a forward portion of the seat; and (b) a fully reclined position, in which the backrest is disposed at a second backrest angle relative to horizontal that is shallower than the first backrest angle, the first footrest is extended in front of the seat, the seat has a second seat angle that is deeper relative to horizontal than the first seat angle, and the seat has a second longitudinal position that is rearward of the first longitudinal position;   wherein the reclining mechanism includes a footrest mechanism attached to the first footrest, the footrest mechanism configured to control relative movement of the first footrest relative to the seat;   a linear actuator attached to the reclining mechanism and the footrest linkage and configured to move the backrest, seat and first footrest between the upright and fully reclined positions;   wherein the linear actuator includes a rail, and wherein the rail defines an angle relative to horizontal of at least 30 degrees in the upright position.   
     
     
         8 . The seating unit defined in  claim 7 , further comprising a second footrest, wherein in the upright position, the second footrest is generally vertically disposed and rearward of the first footrest, and in the fully reclined position the second footrest is generally horizontally disposed and forward of the first footrest. 
     
     
         9 . The seating unit defined in  claim 7 , wherein the reclining mechanism further includes a carrier link that is fixed relative to the seat, and wherein the linear actuator is pivotally attached to a lower forward end portion of the carrier link. 
     
     
         10 . The seating unit defined in  claim 7 , wherein the backrest is fixed to a backpost, and wherein the carrier link is pivotally connected to the backpost.
