Abstract

A simplified, compact, recliner mechanism which can be adapted to essentially any type of seating unit is disclosed. The seat-drop and the over-center linkages, as well as the seat-drop movement, may be eliminated utilizing a simplified recliner linkage and a linear actuator to control movement of the recliner mechanism.

First claim

What is claimed:

1. A linkage mechanism for a seating unit, the linkage mechanism comprising:
an arm mounting bracket;
a back mounting bracket having a first portion and a second portion, the back mounting bracket pivotally coupled to the arm mounting bracket between the first portion and the second portion;
a seat rail link pivotally coupled to the second portion of the back mounting bracket; and
a full recline assembly coupled to the seat rail link forward of the pivotal coupling between the seat rail link and the second portion of the back mounting bracket, the full recline assembly pivotally coupled to the arm mounting bracket forward of the pivotal coupling between the arm mounting bracket and the back mounting bracket.

2. The linkage mechanism of claim 1 , wherein the first portion of the back mounting bracket is configured to couple with a seat back.

3. The linkage mechanism of claim 1 , wherein the seating unit comprises an arm-to-floor seating unit.

4. The linkage mechanism of claim 1 , wherein the seating unit comprises a pivot-over-the arm seating unit.

5. The linkage mechanism of claim 1 , wherein the seating unit comprises a “T” cushion seat.

6. The linkage mechanism of claim 1 , wherein the full recline assembly comprises:
a rear full recline pivot link pivotally coupled to the arm mounting bracket on a third end, the rear full recline pivot link having a fourth end opposite the third end;
a center full recline pivot link pivotally coupled on a fifth end to the fourth end of the rear full recline pivot link, the center full recline pivot link having a sixth end opposite the fifth end, the sixth end of the center full recline pivot link being pivotally coupled to the seat rail link; and
a front full recline pivot link having a seventh end opposite an eighth end, the seventh end pivotally coupled to the arm mounting bracket and the eighth end pivotally coupled to the center full recline pivot link between the fifth end and the sixth end.

7. The linkage mechanism of claim 1 , further comprising an ottoman assembly pivotally coupled to the seat rail link and configured to move between a closed position and an extended position.

8. The linkage mechanism of claim 7 , further comprising a linear actuator coupled to the arm mounting bracket and the ottoman assembly for moving the seating unit between a closed position, an extended position, and a reclined position.

9. A linkage mechanism for a seating unit, the linkage mechanism comprising:
an arm mounting bracket;
a back mounting bracket pivotally coupled to the arm mounting bracket;
a seat rail link pivotally coupled to the back mounting bracket and extending forwardly therefrom;
a full recline assembly coupling the seat rail link to the arm mounting bracket;
a seat rail coupled to the seat rail link; and
an ottoman assembly coupled to the seat rail link and configured to move between a closed position and an extended position.

10. The recline linkage of claim 9 further comprising a linear actuator coupled to the arm mounting bracket and the ottoman assembly for moving the seating unit between a closed position, an extended position, and a reclined position.

11. The recline linkage of claim 9 , wherein the full recline assembly comprises:
a roller coupled to the seat rail link; and
a track coupled to the arm mounting bracket, wherein the roller is operatively engaged in the track, wherein the roller is positioned at one end of the track when the seating unit is in a closed position and is positioned at an opposite end of the track when the seating unit is in a reclined position.

12. The recline linkage of claim 11 , wherein the roller remains at the one end of the track when the seating unit moves from the closed position to the extended position.

13. The recline linkage of claim 9 , wherein the full recline assembly comprises:
a rear full recline pivot link pivotally coupled to the arm mounting bracket;
a center full recline pivot link pivotally coupled to the rear full recline pivot link, the center full recline pivot link also pivotally coupled to the seat rail link; and
a front full recline pivot link pivotally coupled to the arm mounting bracket, the front full recline pivot link also pivotally coupled to the center full recline pivot link.

14. A seating unit comprising:
an arm mounting bracket;
a back mounting bracket having a first end opposite a second end, the back mounting bracket pivotally coupled to the arm mounting bracket between the first end and the second end;
a seat rail link pivotally coupled to the second end of the back mounting bracket; and
a full recline assembly coupled to the seat rail link forward of the pivotal coupling between the seat rail link and the second end of the back mounting bracket, the full recline assembly pivotally coupled to the arm mounting bracket forward of the pivotal coupling between the arm mounting bracket and the back mounting bracket.

15. The seating unit of claim 14 , wherein the seating unit comprises an arm-to-floor seating unit.

16. The seating unit of claim 14 , wherein the seating unit comprises a pivot-over-the arm seating unit.

17. The seating unit of claim 14 , wherein the seating unit comprises a “T” cushion seat.

18. The seating unit of claim 14 , wherein the full recline assembly comprises:
a rear full recline pivot link pivotally coupled to the arm mounting bracket on a third end, the rear full recline pivot link having a fourth end opposite the third end;
a center full recline pivot link pivotally coupled on a fifth end to the fourth end of the rear full recline pivot link, the center full recline pivot link having a sixth end opposite the fifth end, the sixth end of the center full recline pivot link being pivotally coupled to the seat rail link; and
a front full recline pivot link having a seventh end opposite an eighth end, the seventh end pivotally coupled to the arm mounting bracket and the eighth end pivotally coupled to the center full recline pivot link between the fifth end and the sixth end.

19. The seating unit of claim 14 further comprising an ottoman assembly pivotally coupled to the seat rail link and configured to move between a closed position and an extended position.

20. The seating unit of claim 19 further comprising a linear actuator coupled to the arm mounting bracket and the ottoman assembly for moving the seating unit between a closed position, an extended position, and a reclined position.
