Abstract

A recliner heart may include a first locking plate, a second locking plate, a cam and a lubricant member. The first locking plate includes an outer diametrical surface having first teeth formed thereon. The second locking plate is rotatable relative to the first locking plate and includes an inner diametrical surface having second teeth formed thereon. Some of the second teeth are meshingly engaged with some of the first teeth. The cam is connected to the second locking plate and includes a groove formed therein. The lubricant member is disposed in the groove of the cam.

First claim

What is claimed is:

1. A recliner heart comprising:
a first locking plate including an outer diametrical surface having first teeth formed thereon;
a second locking plate rotatable relative to the first locking plate and including a first inner diametrical surface having second teeth formed thereon, some of the second teeth are meshingly engaged with some of the first teeth;
a cam connected to the second locking plate and including a pair of first grooves formed therein; and
a pair of first lubricant members disposed in the first grooves of the cam, wherein the first lubricant members are formed from a material selected from the group consisting of: a fibrous material and a porous polymeric material, wherein the first lubricant members, the cam and an inner section of the first locking plate cooperate to define a lubricant pocket and the lubricant pocket is enclosed between the pair of first lubricant members, the cam and the inner section of the first locking plate.

2. The recliner heart of claim 1 , wherein the second locking plate includes a plate body, a hub and a rim, and wherein the cam is disposed over the hub and the rim includes the first inner diametrical surface having the second teeth formed thereon.

3. The recliner heart of claim 2 , wherein the cam includes a body defining an aperture and an attachment portion, and wherein the first grooves are formed in the attachment portion.

4. The recliner heart of claim 3 , wherein a second inner diametrical surface of the body includes second grooves formed therein, and wherein second lubricant members are disposed within respective second grooves and contact the hub.

5. The recliner heart of claim 4 , wherein the cam is configured to rotate relative to the hub so that the second lubricant members lubricate the hub.

6. The recliner heart of claim 3 , further comprising a bushing ring disposed between the cam and the first locking plate, and wherein the cam is configured to rotate relative to the bushing ring so that the first lubricant members lubricate the bushing ring.

7. The recliner heart of claim 6 , wherein the first lubricant members are substantially cylindrically shaped and each of the first lubricant members includes a flat surface that contacts the bushing ring.

8. The recliner heart of claim 6 , wherein first lubricant members contact the bushing ring, and wherein the first lubricant members and the bushing ring cooperate to form the lubricant pocket, and wherein lubricant in the lubricant pocket lubricates the bushing ring when the cam rotates relative to the bushing ring.

9. The recliner heart of claim 8 , wherein the material of the first lubricant members is resiliently compressible.

10. The recliner heart of claim 1 , wherein the material of the first lubricant members is a felt material that is saturated with lubricant.

11. A recliner heart comprising:
a first locking plate including an outer diametrical surface having first teeth formed thereon;
a second locking plate rotatable relative to the first locking plate and including a first inner diametrical surface having second teeth formed thereon, some of the second teeth are meshingly engaged with some of the first teeth;
a first hub extending through the first and second locking plates and configured to rotate;
a cam rotationally fixed to the first hub;
a first wedge rotationally fixed to the first hub and including a pair of first grooves formed therein;
a pair of first lubricant members disposed in the first grooves of the first wedge;
a bushing ring disposed between the cam and the first locking plate, wherein the pair of first lubricant members, the first wedge and the bushing ring cooperate to define a lubricant pocket and the lubricant pocket is enclosed between the pair of first lubricant members, the first wedge and an inside surface of the bushing ring, wherein the first hub, the cam, and the first wedge are configured to rotate relative to the bushing ring so that the first lubricant members lubricate the bushing ring; and
a second wedge disposed between the cam and the bushing ring and rotationally fixed to the first hub, wherein the second wedge includes a second groove formed therein.

12. The recliner heart of claim 11 , wherein the second locking plate includes a plate body, a second hub and a rim, and wherein the cam is disposed over the second hub and the rim includes the first inner diametrical surface having the second teeth formed thereon.

13. The recliner heart of claim 12 , wherein the first wedge is disposed between the cam and the bushing ring and includes a third groove formed therein, and wherein a second lubricant member is disposed in the third groove.

14. The recliner heart of claim 13 , further comprising a third lubricant member disposed in the second groove, and wherein the third lubricant member contacts the bushing ring.

15. The recliner heart of claim 14 , wherein the cam includes a body defining an aperture and a distal portion, and wherein the first and second wedges are positioned at opposites sides of the distal portion.

16. A recliner heart comprising:
a first locking plate including an outer diametrical surface having first teeth formed thereon;
a second locking plate rotatable relative to the first locking plate and including a first inner diametrical surface having second teeth formed thereon, some of the second teeth are meshingly engaged with some of the first teeth;
a cam connected to the second locking plate;
a bushing ring disposed between the cam and the first locking plate; and
a plurality of lubricant members attached to the cam, wherein the cam, the bushing ring, and two of the plurality of lubricant members cooperate to form a pocket that moves as the cam rotates relative to the bushing ring, and wherein the pocket is at least partially disposed between the two of the plurality of lubricant members.

17. The recliner heart of claim 16 , wherein the plurality of lubricant members are made of a resiliently compressible material.

18. The recliner heart of claim 16 , wherein the pocket contains lubricant therein that lubricates the bushing ring as the cam rotates.

19. The recliner heart of claim 16 , wherein the plurality of lubricant members are made of a felt material that is saturated with lubricant.

20. The recliner heart of claim 16 , wherein the plurality of lubricant members are made of a porous polymeric material.
