Abstract

A furniture member may include a base frame and a seat assembly mounted on the base frame. The seat assembly may include a seat frame, a seatback, a seat bottom, and a legrest mechanism. The legrest mechanism may be mounted to the seat frame and attached to a legrest platform. The legrest mechanism may include a drive rod coupled to a pantograph linkage that is movable relative to the seat frame between retracted and extended positions.

First claim

What is claimed is:

1. A furniture member comprising:
a base frame; and
a seat frame mounted on the base frame;
a seatback mounted to the seat frame;
a seat bottom mounted to the seat frame; and
a legrest mechanism mounted to the seat frame and attached to a legrest platform, the legrest mechanism including a pantograph linkage that is movable relative to the seat frame between a retracted position and an extended position,
wherein the legrest mechanism includes a mid-ottoman bracket non-rotatably attached to a link of the pantograph linkage, the mid-ottoman bracket is disposed between the seat bottom and the legrest platform when the pantograph linkage is in the extended position.

2. The furniture member of claim 1 , wherein the mid-ottoman bracket is removably attached to the link of the pantograph linkage with a fastener.

3. The furniture member of claim 2 , wherein the pantograph linkage includes a first support link, a swing link, a second support link, a cross link, a third support link, a bracket link, wherein the legrest platform is mounted to the bracket link, and wherein the first support link, the swing link, the second support link, the cross link, and the third support link are flat and free of offsets.

4. The furniture member of claim 3 , wherein the first support link and the third support link are in line with each other.

5. The furniture member of claim 4 , wherein the swing link, the cross link, and a portion of the bracket link are in line with each other.

6. The furniture member of claim 5 , wherein the first support link has a varying width.

7. The furniture member of claim 6 , further comprising a front swing link having a first end pivotably coupled to a first bracket fixedly attached to the seat bottom and a second end pivotably coupled to a second bracket fixedly attached to one or both of a front rail plate and a side rail plate of the seat frame.

8. The furniture member of claim 7 , wherein the seatback is rotatable relative to the seat bottom between a reclined position and an upright position, wherein rotation of the seatback causes rotation of the front swing link relative to the seat frame, and wherein rotation of the front swing link relative to the seat frame moves the seat bottom relative to the seat frame.

9. The furniture member of claim 1 , further comprising a rocker member attached to the seat frame and rollingly contacting the base frame, wherein the rocker member supports the seat frame relative to the base frame such that the seat frame is movable between a rocked-back tilt position and a rocked-forward tilt position.

10. A furniture member comprising:
a base frame; and
a seat frame mounted on the base frame;
a seatback mounted to the seat frame;
a seat bottom mounted to the seat frame; and
a legrest mechanism mounted to the seat frame and attached to a legrest platform, the legrest mechanism including a pantograph linkage that is movable relative to the seat frame between a retracted position and an extended position,
wherein the pantograph linkage includes a first support link, a swing link, a second support link, a cross link, a third support link, a bracket link, wherein the legrest platform is mounted to the bracket link, and wherein the first support link, the swing link, the second support link, the cross link, and the third support link are flat and free of offsets.

11. The furniture member of claim 10 , wherein the first support link and the third support link are in line with each other.

12. The furniture member of claim 11 , wherein the swing link, the cross link, and a portion of the bracket link are in line with each other.

13. The furniture member of claim 12 , wherein the first support link has a varying width.

14. The furniture member of claim 12 , wherein the legrest mechanism includes a mid-ottoman bracket non-rotatably attached to the cross link of the pantograph linkage, the mid-ottoman bracket is disposed between the seat bottom and the legrest platform when the pantograph linkage is in the extended position.

15. The furniture member of claim 14 , wherein the mid-ottoman bracket is removably attached to the cross link of the pantograph linkage with a fastener.

16. The furniture member of claim 12 , further comprising a front swing link having a first end pivotably coupled to a first bracket fixedly attached to the seat bottom and a second end pivotably coupled to a second bracket fixedly attached to one or both of a front rail plate and a side rail plate of the seat frame.

17. The furniture member of claim 16 , wherein the seatback is rotatable relative to the seat bottom between a reclined position and an upright position, wherein rotation of the seatback causes rotation of the front swing link relative to the seat frame, and wherein rotation of the front swing link relative to the seat frame moves the seat bottom relative to the seat frame.

18. The furniture member of claim 10 , further comprising a rocker member attached to the seat frame and rollingly contacting the base frame, wherein the rocker member supports the seat frame relative to the base frame such that the seat frame is movable between a rocked-back tilt position and a rocked-forward tilt position.
