Abstract

A linkage for use in reclining furniture may include a back bracket supported by forward and rear back pivot links. The bottom of the rear back pivot link may be pivotably coupled to a rear lift link and the bottom of the forward back pivot link may be pivotably coupled to the rear lift link in a different location. A control link may be pivotably coupled on one end to one of the forward back pivot link and the rear back pivot link. The control link may pull the pivoting linkage of the back bracket and the forward and back pivot links as the overall linkage is moved from a closed to a TV to a full-recline position. The resulting pivot point for the back is projected upwardly and forwardly, to a point where an upholstered back and seat meet on a finished chair.

First claim

The invention claimed is:

1. A linkage for use in rocking-reclining furniture comprising:
a rocker cam;
a base plate coupled to the rocker cam;
a motor bell crank;
a motor tube coupled to the motor bell crank;
and
a strut having a first end opposite a second end, the strut pivotably coupled proximate the first end to the motor bell crank, the strut pivotably coupled proximate the second end to the base plate.

2. The linkage of claim 1 further comprising:
the motor bell crank having an inward facing surface;
the base plate having an outward facing surface; and
the strut having a strut inward facing surface and a strut outward facing surface, the strut inward facing surface being adjacent to the outward facing surface of the base plate, the strut outward facing surface being adjacent to the inward facing surface of the motor bell crank.

3. The linkage of claim 1 further comprising:
the motor bell crank being substantially planar and positioned in a first plane;
the strut being substantially planar and positioned in a second plane; and
the base plate being substantially planar and positioned in a third plane, wherein the second plane is between the first plane and the third plane.

4. The linkage of claim 3 , wherein the first plane, the second plane, and the third plane are each parallel to one another.

5. The linkage of claim 1 further comprising the motor bell crank being pivotably coupled with a front lift link.

6. The linkage of claim 1 further comprising a back bracket that pivots relative to a seat mounting plate about a projected pivot point.

7. The linkage of claim 6 , wherein the projected pivot point is forward and above a rearward end of the seat mounting plate.

8. The linkage of claim 6 further comprising:
a rear lift link positioned below the back bracket;
a forward back pivot link pivotably coupled to the back bracket at a first pivot point and pivotably coupled at a second pivot point to one of a seat mounting plate and the rear lift link;
a rear back pivot link pivotably coupled to the back bracket at a third pivot point and pivotably coupled to the rear lift link at a fourth pivot point, the third pivot point being rearward of the first pivot point, the fourth pivot point being rearward of the second pivot point; and
a control link having a first end opposite a second end, the first end pivotably coupled to the forward back pivot link at a fifth pivot point, and the second end pivotably coupled to a front lift link, the fifth pivot point being intermediate to the first pivot point and the third pivot point.

9. A linkage for use in gliding-reclining furniture comprising:
a glide bracket;
a first glide link and a second glide link, each pivotally coupled to the glide bracket;
a base plate pivotally coupled to the first glide link and the second glide link;
a motor bell crank;
a motor tube coupled to the motor bell crank; and
a strut having a first end opposite a second end, the strut pivotably coupled proximate the first end to the motor bell crank, the strut pivotably coupled proximate the second end to the base plate.

10. The linkage of claim 9 , wherein the glide bracket is coupled to a base rail.

11. The linkage of claim 9 , wherein the linkage is configured to glide above the glide bracket.

12. The linkage of claim 9 further comprising:
a front pivot link coupled to the base plate forward of the strut; and
a rear pivot link coupled to the base plate rearward of the strut.

13. The linkage of claim 12 further comprising:
a front lift link;
a rear lift link; and
a seat mounting plate,
wherein the front lift link is pivotally mounted to the front pivot link and pivotally coupled to the seat mounting plate, and the rear lift link is pivotally coupled to the rear pivot link and pivotally coupled to the seat mounting plate.

14. The linkage of claim 13 further comprising:
a rear back pivot link pivotally coupled the rear lift link;
a back bracket pivotally coupled to the rear back pivot link; and
a forward back pivot link pivotally coupled to the back bracket, the forward back pivot link being pivotally coupled to the rear lift link.

15. The linkage of claim 14 further comprising a rearward portion of a control link pivotally coupled to the forward back pivot link, a forward portion of the control link pivotally coupled to the front lift link.
