Abstract

A seat assembly includes a seat back that is pivotable about an axis of rotation, and a reclining assembly. The reclining assembly includes a base, a carrier secured to the base and including a rod guide, a curved rod interfacing the rod guide, a spring having a fixed end and a rotatable end, and a curved spring housing that extends over the spring.

Claims

1. A vehicle seat assembly comprising:

a seat back that is pivotable about an axis of rotation and including a first connector; and

a reclining assembly that includes

a base adapted to be mounted to a portion of a vehicle,

a carrier secured to the base and including a rod guide,

a curved rod interfacing the rod guide for movement relative to the base, wherein the curved rod has a radius of curvature that extends from an origin proximate the axis of rotation when the seat assembly is mounted in the vehicle,

a second connector attached to the curved rod and attachable to the first connector, and

a spring disposed about the curved rod and having a fixed end that is fixed relative to the base and a movable end that is movable with respect to the fixed end, wherein the spring is movable between a first orientation for retaining the curved rod with respect to the base and a second orientation for allowing the curved rod to move with respect to the base to adjust pivot angle of the seat back.

2. The vehicle seat assembly of claim 1 wherein the carrier is formed integrally with the base.

3. The vehicle seat assembly of claim 1 wherein the curved spring housing includes a transverse slot that receives the movable end therein, the movable end being biased into engagement with a wall of the transverse slot when the movable end is in a first orientation.

4. The vehicle seat assembly of claim 3 wherein in the first orientation, an inner surface of the spring engages the curved rod to substantially inhibit movement of the curved rod relative to the carrier.

5. The vehicle seat assembly of claim 3 wherein rotation of the movable end through the transverse slot to a second orientation increases an internal diameter of the spring, and wherein in the second orientation, an inner surface of the spring is spaced apart from the curved rod to permit movement of the curved rod relative to the carrier.

6. An adjustable connector assembly for use with a vehicle seat back pivotally mounted in a vehicle, the connector assembly comprising:

a base adapted to be mounted to a portion of the vehicle;

a carrier secured to the base and including a rod guide;

a curved rod interfacing the rod guide for movement relative to the base, the curved rod defining a first curved central axis;

a connector attached to the curved rod and attachable to the seat back; and

a spring disposed about an outer perimeter of the curved rod, the spring having a fixed end and a movable end, wherein the spring is movable between a first orientation for retaining the curved rod with respect to the base and a second orientation for allowing the curved rod to move with respect to the base.

7. The adjustable connector assembly of claim 6 wherein the spring is a curved spring defining a third curved central axis that is coaxial with the first curved central axis.

8. The adjustable connector assembly of claim 6 wherein the curved rod includes a radius in the range of approximately 350 mm to approximately 550 mm.

9. The adjustable connector assembly of claim 6 further comprising a striker secured to the curved rod at a first end of the curved rod, the striker defining at least a portion of a latch interface.

10. The adjustable connector assembly of claim 9 further comprising an end cap secured to the curved rod at a second end of the curved rod opposite the first end.

11. The adjustable connector assembly of claim 6 wherein the carrier is a first carrier defining a first central axis, and wherein the adjustable connector assembly further comprises a second carrier secured to the base and including a second rod guide defining a second central axis that intersects the first central axis at an oblique angle.

12. A vehicle seat adjustable striker assembly comprising:

a base adapted to be mounted to a portion of a vehicle;

a first carrier secured to the base and including a first rod guide defining a first central axis;

a second carrier secured to the base and including a second rod guide defining a second central axis that intersects the first central axis at an oblique angle;

a spring housing extending between the first and second carriers; and

a spring disposed at least partially within the spring housing and extending between the first and second carriers.

13. The vehicle seat adjustable striker assembly of claim 12 wherein the spring housing is a curved spring housing that defines a curved central axis.

14. The vehicle seat adjustable striker assembly of claim 12 wherein the spring is an eccentrically-loaded spring having a fixed end and a rotatable end.

15. The vehicle seat adjustable striker assembly of claim 14 further comprising a spring retainer disposed at an inboard surface of the first carrier, the spring retainer including a retention post that receives the fixed end of the spring.

16. The vehicle seat adjustable striker assembly of claim 14 wherein the spring housing includes a transverse slot extending through a wall of the spring housing, wherein the rotatable end of the spring extends at least partially through the transverse slot.

17. The vehicle seat adjustable striker assembly of claim 16 wherein the transverse slot extends at least 45 degrees about a central axis of the spring housing.

18. The vehicle seat adjustable striker assembly of claim 16 further comprising a handle secured to the rotatable end of the spring proximate the transverse slot.

19. The vehicle seat adjustable striker assembly of claim 16 wherein rotational movement of the rotatable end of the spring through the transverse slot increases an internal diameter of the spring from a first diameter to a second diameter.

20. The vehicle seat adjustable striker assembly of claim 16 further comprising a second spring disposed within the spring housing, the second spring including a second fixed end and a second rotatable end that extends through the transverse slot.
