Abstract

A seat adjustment first lever is adapted to be mounted to a first lateral end of a recline mechanism of a seatback. Rotation of the first lever about a pivot axis disengages the recline mechanism. The first lever includes a first lever input portion extending from the pivot axis for manual rotation of the first lever. A second lever input portion extends from the pivot axis and is sized to receive an input cable for actuation of the first lever from a remote location. A lever output portion extends from the pivot axis and is sized to receive an output cable to connect the first lever to a second lever on a second lateral end of the recline mechanism.

First claim

What is claimed is:

1. A seat adjustment assembly comprising:
a seat adjustment first lever adapted to be mounted to a first lateral end of a recline mechanism of a seatback, whereby rotation of the first lever about a pivot axis disengages the recline mechanism, the first lever comprising:
a first lever input portion extending from the pivot axis for manual rotation of the first lever,
a lever output portion extending from the pivot axis and sized to receive an output cable to connect the first lever to a second lever on a second lateral end of the recline mechanism, and
a second lever input portion extending from the pivot axis and sized to receive an input cable for actuation of the first lever from a remote location;

the input cable attached to the second lever input portion and extending to a remote location spaced apart from the seatback; and
a manual lever oriented in the remote location and connected to the input cable so that rotation of the manual lever actuates the input cable to rotate the first lever and to disengage the recline mechanism to pivot the seatback.

2. The seat adjustment assembly of claim 1 , further comprising a strap attached to a distal end of the first lever input portion for manual rotation of the first lever to rotate the first lever and to disengage the recline mechanism to pivot the seatback.

3. The seat adjustment assembly of claim 2 wherein a slot is formed in the distal end of the first lever input portion, and the slot is sized to receive the strap.

4. The seat adjustment assembly of claim 1 , further comprising:
the second lever adapted to be connected to a second lateral end of the recline mechanism; and
the output cable connected to the first lever output portion of the first lever and connected to the second lever so that rotation of the first lever rotates the second lever to coordinate disengagement of the recline mechanism at the first lateral end and the second lateral end.

5. The seat adjustment assembly of claim 4 further comprising a first biasing member cooperating with the first lever to bias the first lever toward an engaged position of the recline mechanism.

6. The seat adjustment assembly of claim 5 further comprising a second biasing member cooperating with the second lever to bias the second lever toward the engaged position of the recline mechanism.

7. A seat assembly comprising:
a pair of spaced apart seat support brackets;
a seatback pivotally connected to the pair of spaced apart seat support brackets;
a recline mechanism connected to the pair of spaced apart seat support brackets and the seatback, the recline mechanism having an engaged position whereby the seatback is locked relative to the pair of spaced apart seat support brackets, and a disengaged position whereby the seatback is pivotally adjustable relative to the pair of spaced apart seat support brackets; and
the seat adjustment assembly according to claim 4 , wherein the first lever is mounted to a first lateral end of the recline mechanism and the second lever is mounted to a second lateral end of the recline mechanism.

8. A seating arrangement comprising a first seat assembly and a second seat assembly, each according to claim 7 , aligned adjacent each other as a common seating row, wherein the first lever of each seat assembly is oriented laterally outboard and the second lever of each seat assembly is oriented laterally inboard and adjacent the other second lever.

9. A vehicle assembly comprising a seating arrangement with a seat assembly oriented in a seating row, the seat assembly comprising the seat arrangement of claim 1 wherein the remote location is oriented in another row or compartment of the vehicle assembly.

10. A vehicle assembly comprising a seating arrangement with a seat assembly oriented in a seating row, and a rear opening of the vehicle assembly, the seat assembly comprising the seat adjustment assembly of claim 1 wherein the remote location is oriented adjacent the rear opening.

11. A seat adjustment assembly comprising:
a first lever adapted to be mounted to a first lateral end of a recline mechanism of a seatback, whereby rotation of the first lever about a pivot axis disengages the recline mechanism, a first lever input portion extending from the pivot axis of the first lever for manual rotation of the first lever;
an output cable connected to a lever output portion of the first lever and connected to a second lever on a second lateral end of the recline mechanism;
an input cable connected to a second lever input portion of the first lever for actuation of the first lever from a remote location spaced apart from the seatback; and
a manual lever oriented in the remote location and connected to the input cable so that rotation of the manual lever actuates the input cable to rotate the first lever and to disengage the recline mechanism to pivot the seatback.

12. The seat adjustment assembly of claim 11 further comprising a strap attached to a distal end of the first lever input portion for manual rotation of the first lever to rotate the first lever and to disengage the recline mechanism to pivot the seatback.

13. The seat adjustment assembly of claim 11 further comprising:
the second lever adapted to be connected to a second lateral end of the recline mechanism; and
the output cable connected to the lever output portion of the first lever and connected to the second lever so that rotation of the first lever rotates the second lever to coordinate disengagement of the recline mechanism at the first lateral end and the second lateral end.

14. The seat adjustment assembly of claim 13 further comprising a first biasing member cooperating with the first lever to bias the first lever toward an engaged position of the recline mechanism.

15. The seat adjustment assembly of claim 14 further comprising a second biasing member cooperating with the second lever to bias the second lever toward the engaged position of the recline mechanism.

16. A seat assembly comprising:
a pair of spaced apart seat support brackets;
a seatback pivotally connected to the pair of spaced apart seat support brackets;
a recline mechanism connected to the pair of spaced apart seat support brackets and the seatback, the recline mechanism having an engaged position whereby the seatback is locked relative to the pair of spaced apart seat support brackets, and a disengaged position whereby the seatback is pivotally adjustable relative to the pair of spaced apart seat support brackets; and
the seat adjustment assembly according to claim 13 , wherein the first lever is mounted to a first lateral end of the recline mechanism and the second lever is mounted to a second lateral end of the recline mechanism.

17. A seating arrangement comprising a first seat assembly and a second seat assembly, each according to claim 16 , aligned adjacent each other as a common seating row, wherein the first lever of each seat assembly is oriented laterally outboard and the second lever of each seat assembly is oriented laterally inboard and adjacent the other second lever.

18. A vehicle assembly comprising a seating arrangement with a seat assembly oriented in a seating row, the seat assembly comprising the seat adjustment assembly of claim 11 wherein the remote location is oriented in another row or compartment of the vehicle assembly.

19. A vehicle assembly comprising a seating arrangement with a seat assembly oriented in a seating row, and a rear opening of the vehicle assembly, the seat assembly comprising the seat adjustm
