Abstract

A recliner mechanism includes a housing plate and a recliner heart. The housing plate includes a plate body. The recliner heart is mounted to the housing plate and operable in an unlocked state permitting relative rotation between a seat back and a seat bottom, and a locked state preventing relative rotation between the seatback and the seat bottom. The housing plate includes a fore end proximate a front of the seat bottom and an aft end opposing the fore end and proximate a rear end of the seat bottom. The plate body includes a protrusion extending outwardly therefrom at or near the aft end.

First claim

What is claimed is:

1. A recliner mechanism comprising:
a housing plate including a planar plate body; and
a recliner heart mounted to the housing plate and operable in an unlocked state permitting relative rotation between a seatback and a seat bottom, and a locked state preventing relative rotation between the seatback and the seat bottom,
wherein the housing plate includes a fore end proximate a front of the seat bottom and an aft end opposing the fore end and proximate a rear end of the seat bottom, the planar plate body includes a second protrusion extending outwardly therefrom at or near the aft end,
wherein the planar plate body includes a first protrusion extending outwardly therefrom at or near the fore end of the housing plate, and
wherein when the first and second protrusions are in non-deformed states prior to absorbing a force associated with a vehicle impact event, a first distance between a surface of the planar plate body and a peak of the first protrusion is different from a second distance between the surface of the planar plate body and a second peak of the second protrusion.

2. The recliner mechanism of claim 1 , wherein the first and second protrusions are allowed to absorb energy and deform upon an impact event, thereby reducing energy transferred to the recliner heart.

3. The recliner mechanism of claim 1 , wherein the first and second protrusions are allowed to absorb energy and stretch upon an impact event, thereby reducing energy transferred to the recliner heart.

4. The recliner mechanism of claim 1 , wherein the first and second protrusions are allowed to absorb energy and collapse upon an impact event, thereby reducing energy transferred to the recliner heart.

5. The recliner mechanism of claim 1 , wherein the housing plate includes a flange extending from and at least partially around the planar plate body, and wherein the flange and the first and second protrusions extend in the same direction.

6. The recliner mechanism of claim 1 , wherein the planar plate body defines an opening extending therethrough such that an end of the second protrusion is spaced apart from the planar plate body.

7. The recliner mechanism of claim 1 , wherein the second protrusion is an elongated protrusion extending from the aft end of the housing plate toward the fore end of the housing plate.

8. The recliner mechanism of claim 1 , wherein the second protrusion has a first end positioned at or near the aft end and a second end positioned closer to the fore end than the aft end, and wherein the second protrusion is curved along a length thereof from the first end to the second end.

9. The recliner mechanism of claim 1 , wherein the first protrusion partially defines an opening in the housing plate.

10. The recliner mechanism of claim 9 , wherein the first protrusion is integrally formed with the housing plate and is formed from the same sheet metal as the housing plate, and wherein the first protrusion has a V-shaped or U-shaped cross section.

11. The recliner mechanism of claim 6 , wherein a curved slot is formed in the planar body of housing plate, and wherein the curved slot is disposed between the first and second protrusions and is partially defined by the first protrusion.

12. A recliner mechanism comprising:
a housing plate including a planar plate body; and
a recliner heart mounted to the housing plate and operable in an unlocked state permitting relative rotation between a seatback and a seat bottom, and a locked state preventing relative rotation between the seatback and the seat bottom,
wherein the housing plate includes a fore end proximate a front of the seat bottom and an aft end opposing the fore end and proximate a rear end of the seat bottom, the planar plate body includes a first protrusion extending outwardly therefrom at or near the fore end and a second protrusion extending outwardly therefrom at or near the aft end,
wherein a curved slot is formed in the planar body of the housing plate, and wherein the curved slot is disposed between the protrusions and is partially defined by the first protrusion, and
wherein the second protrusion partially defines an opening in the housing plate, and wherein the opening is partially defined by the planar body of the housing plate.

13. The recliner mechanism of claim 12 , wherein the housing plate includes a flange extending from and at least partially around the planar plate body, and wherein the flange and the first and second protrusions extend in the same direction.

14. The recliner mechanism of claim 13 , wherein the second protrusion is an elongated protrusion extending from the aft end of the housing plate toward the fore end of the housing plate.

15. The recliner mechanism of claim 14 , wherein when the first and second protrusions are in non-deformed states prior to absorbing a force associated with a vehicle impact event, a first distance between a surface of the planar plate body and a peak of the first protrusion is different from a second distance between the surface of the planar plate body and a second peak of the second protrusion.

16. The recliner mechanism of claim 15 , wherein the second protrusion is curved along a length thereof extending between the aft and fore ends.

17. The recliner mechanism of claim 16 , wherein the first and second protrusions are integrally formed with the housing plate and are formed from the same sheet metal as the housing plate, and wherein the first and second protrusions have a V-shaped or U-shaped cross section.
