- 8. The article of furniture of claim 7 wherein said third board link pivots about said pivotal interconnection between its third portion and said support link in response to pivotable movement of said first board link.
- 9. The article of furniture of claim 7 wherein said pivotal interconnection between said third portion of said third board link and said first end of said support link is common with said pivotal interconnection between said first end of said support link and said second connector link.
- 10. The article of furniture of claim 7 wherein said pivotal interconnection between said second portion of said third board link and said first board link is common with said pivotal interconnection between said second connector link and said first board link.
- 11. The article of furniture of claim 7 wherein said pivotal interconnection between said second portion of said third board link and said first board link is common with said pivotal interconnection between said second connector link and said first board link.
- 12. The article of furniture of claim 7 wherein said primary and secondary leg rest panels are upholstered members.
- 13. In an article of furniture having a seat assembly supported from a chair frame and an actuation mechanism for enabling a dual leg rest assembly to move between a stowed position and an extended position, said dual leg rest assembly comprising:
- a first leg rest panel;
- a pantograph linkage interconnecting said first leg rest panel to the actuation mechanism for articulated movement of said first leg rest panel from the stowed position to the extended position;
- an ottoman panel; and
- an ottoman link having a bracket portion on which said ottoman panel is secured, a first pivot portion pivotably interconnected to a first link and a second link of said pantograph linkage such that said first link is interdisposed between said ottoman link and said second link, and a second pivot portion pivotably coupled to said second link of said pantograph linkage, whereby said ottoman panel moves along an arcuate path relative to said second pivot portion in response to articulated movement of said pantograph linkage.
- 14. In an article of furniture having a seat assembly supported from a chair frame and an actuation mechanism for enabling a dual leg rest assembly to move between a stowed position and an extended position, said dual leg rest assembly comprising:
- a first leg rest panel;
- a pantograph linkage interconnecting said first leg rest panel to the actuation mechanism for articulated movement of said first leg rest panel from the stowed position to the extended position, said pantograph linkage including a drive link operably coupled to the actuation mechanism at a first end and pivotally connected to a support link at a second end;
- an ottoman panel; and
- an ottoman link having a bracket portion on which said ottoman panel is secured, a first pivot portion pivotably interconnected to a first board link of said pantograph linkage, and a second pivot portion pivotably coupled to connection link of said pantograph linkage and said support link, said pivotal connection between said drive link and said support link is substantially colinear with said first end of said drive link and said second pivot portion of said ottoman link when the leg rest assembly is in the extended position whereby said ottoman panel moves along an arcuate path relative to said second pivot portion in response to articulated movement of said pantograph linkage.
- 15. The leg rest assembly of claim 14 wherein said pantograph linkage further comprises:
