Abstract

A vehicle seat easy entry system includes a vehicle seat having a seat bottom and a seat back. A seat track assembly receives the vehicle seat and selectively allows forward and rearward travel of the seat bottom. A seat track locking mechanism is engageable to lock the seat bottom with respect to the seat track assembly. A recliner mechanism controls an orientation of the seat back. The recliner mechanism is engageable to lock the seat back with respect to the seat bottom. An easy entry handle is arranged such that assertion of the easy entry handle releases the seat track locking mechanism. The seat track assembly and the recliner mechanism are configured such that movement of the seat bottom to a forward position releases the recliner mechanism, thereby allowing the seat back to rotate to an easy entry position.

Claims

1. A vehicle seat easy entry system comprising:

a vehicle seat including a seat bottom and a seat back;

a seat track assembly including a seat track locking mechanism, the seat track assembly receiving the vehicle seat and selectively allowing forward and rearward travel of the seat bottom with respect to a portion of the seat track assembly, the seat track locking mechanism being engageable to lock the seat bottom with respect to the portion of the seat track assembly;

a recliner mechanism for controlling an orientation of the seat back with respect to the seat bottom, the recliner mechanism being engageable to lock the seat back with respect to the seat bottom; and

an easy entry handle arranged such that assertion of the easy entry handle releases the seat track locking mechanism;

wherein the seat track assembly and the recliner mechanism are configured such that movement of the seat bottom to a forward position releases the recliner mechanism, thereby allowing the seat back to rotate to an easy entry position.

2. The vehicle seat easy entry system of claim 1 wherein the seat track assembly allows forward and rearward travel of the seat bottom over a travel range including the forward position, a plurality of middle positions, and a rearward position.

3. The vehicle seat easy entry system of claim 1 wherein the recliner mechanism allows rotation of the seat back with respect to the seat bottom over a travel range between the easy entry position and a seating position.

4. The vehicle seat easy entry system of claim 1 wherein the easy entry handle is located at the seat back.

5. The vehicle seat easy entry system of claim 1 further comprising:

a tow bar operatively connected to the seat track assembly to allow a user to manually adjust a position of the seat bottom.

6. The vehicle seat easy entry system of claim 1 further comprising:

a cable arrangement connecting the easy entry handle and the seat track locking mechanism.

7. The vehicle seat easy entry system of claim 6 wherein the seat track assembly allows forward and rearward travel of the seat bottom over a travel range including the forward position, a plurality of middle positions, and a rearward position.

8. The vehicle seat easy entry system of claim 6 wherein the recliner mechanism allows rotation of the seat back with respect to the seat bottom over a travel range between the easy entry position and a seating position.

9. The vehicle seat easy entry system of claim 6 wherein the easy entry handle is located at the seat back.

10. The vehicle seat easy entry system of claim 6 further comprising:

a tow bar operatively connected to the seat track assembly to allow a user to manually adjust a position of the seat bottom.

18. The vehicle seat easy entry system of claim 1 further comprising:

a tow bar operatively connected to the seat track assembly to allow a user to manually adjust a position of the seat bottom within a first range of forward and rearward travel, wherein a first stop limits forward movement of the seat bottom caused by operation of the tow bar, and a second stop forward of the first stop limits forward movement of the seat bottom when the easy entry handle was asserted.

11. A vehicle seat easy entry system comprising:

a vehicle seat including a seat bottom and a seat back;

a seat track assembly including a seat track locking mechanism, the seat track assembly receiving the vehicle seat and selectively allowing forward and rearward travel of the seat bottom with respect to a portion of the seat track assembly over a travel range including a forward position, a plurality of middle positions, and a rearward position, the seat track locking mechanism being engageable to lock the seat bottom with respect to the portion of the seat track assembly;

a recliner mechanism for controlling an orientation of the seat back with respect to the seat bottom to allow rotation of the seat back with respect to the seat bottom over a travel range between an easy entry position and a seating position, the recliner mechanism being engageable to lock the seat back with respect to the seat bottom; and

an easy entry handle arranged such that assertion of the easy entry handle releases the seat track locking mechanism;

wherein the seat track assembly and the recliner mechanism are configured such that movement of the seat bottom to the forward position releases the recliner mechanism, thereby allowing the seat back to rotate to the easy entry position.

12. The vehicle seat easy entry system of claim 11 wherein the easy entry handle is located at the seat back.

13. The vehicle seat easy entry system of claim 11 further comprising:

a tow bar operatively connected to the seat track assembly to allow a user to manually adjust a position of the seat bottom.

14. The vehicle seat easy entry system of claim 11 further comprising:

a cable arrangement connecting the easy entry handle and the seat track locking mechanism.

15. The vehicle seat easy entry system of claim 14 wherein the easy entry handle is located at the seat back.

16. The vehicle seat easy entry system of claim 14 further comprising:

a tow bar operatively connected to the seat track assembly to allow a user to manually adjust a position of the seat bottom.

17. The vehicle seat easy entry system of claim 11 further comprising:

a tow bar operatively connected to the seat track assembly to allow a user to manually adjust a position of the seat bottom, wherein a first stop limits forward movement of the seat bottom caused by operation of the tow bar, and a second stop forward of the first stop limits forward movement of the seat bottom when the easy entry handle was asserted.

19. A vehicle seat with an easy entry system comprising:

a vehicle seat including a seat bottom and a seat back;

a seat track assembly including a seat track locking mechanism, the seat track assembly receiving the vehicle seat and selectively allowing forward and rearward travel of the seat bottom with respect to a portion of the seat track assembly, the seat track locking mechanism being engageable to lock the seat bottom with respect to the portion of the seat track assembly;

a recliner mechanism configured to control an orientation of the seat back with respect to the seat bottom, the recliner mechanism being engageable to lock the seat back with respect to the seat bottom;

a tow bar operatively connected to the seat track assembly to allow a user to manually adjust a position of the seat bottom within a first range of the forward and rearward travel, wherein a first stop limits forward movement of the seat bottom caused by operation of the tow bar; and

an easy entry handle that is actuatable to release the seat track locking mechanism to allow the seat bottom to move forward past the first stop to thereby release the recliner mechanism and allow the seat back to rotate to an easy entry position.
