Abstract

An easy entry seat assembly may include a seat frame having a seat bottom and a backrest supported for pivotal movement relative to the seat bottom. A reclining mechanism may be provided on the seat frame to selectively control pivotal movement of the backrest relative to the seat bottom. A backrest stopper mechanism may be provided on the seat frame. The backrest stopper mechanism may include an easy entry stopper that can be movable from a non-actuated position to an actuated position to stop pivotal movement of the backrest in an easy entry position. An easy entry actuator may be provided on the seat frame, wherein operation of the easy entry actuator can cause movement of the easy entry stopper to the actuated position and release the reclining mechanism.

Claims (31)

1. An easy entry seat assembly comprising:

a seat frame having a seat bottom and a backrest, the backrest configured for pivotal movement relative to the seat bottom;

a reclining mechanism provided on the seat frame to selectively control pivotal movement of the backrest relative to the seat bottom;

a backrest stopper mechanism provided on the seat frame, the backrest stopper mechanism including an easy entry stopper that is movable from a non-actuated position to an actuated position to stop pivotal movement of the backrest in an easy entry position; and

an easy entry actuator provided on the seat frame, wherein operation of the easy entry actuator causes movement of the easy entry stopper to the actuated position and releases the reclining mechanism

wherein the reclining mechanism includes a recliner lever, and operation of the recliner lever is configured to move the easy entry stopper from the actuated position to the non-actuated position.

2. The easy entry seat assembly of claim 1 , wherein the easy entry stopper is mounted on or connected to the seat frame by a pivot pin for pivotal movement.

3. The easy entry seat assembly of claim 1 , wherein the easy entry stopper is mounted on or connected to a portion of the seat frame that remains generally stationary relative to pivotal movement of the backrest.

4. The easy entry seat assembly of claim 1 , wherein the easy entry stopper is biased in the actuated position by a biasing mechanism.

5. The easy entry seat assembly of claim 1 , wherein the easy entry stopper includes a tab that is received within a slot formed in the seat frame to limit a range of motion of the easy entry stopper.

6. The easy entry seat assembly of claim 1 , wherein a portion of the backrest is configured to contact the easy entry stopper when the easy entry stopper is in the actuated position.

7. The easy entry seat assembly of claim 6 , wherein the backrest includes a backrest stopper mechanism that is configured to contact the easy entry stopper when the easy entry stopper is in the actuated position.

8. The easy entry seat assembly of claim 1 , wherein the backrest stopper mechanism further includes a latch member that is movable between a locked position to lock the easy entry stopper in the non-actuated position and an unlocked position to release the easy entry stopper to the actuated position.

9. The easy entry seat assembly of claim 8 , wherein the reclining lever includes a handle to facilitate pivotal movement of the reclining lever.

10. The easy entry seat assembly of claim 8 , wherein the latch member includes a latching portion that is configured to engage the easy entry stopper and lock the easy entry stopper in the non-actuated position.

11. The easy entry seat assembly of claim 1 , further including an actuating mechanism that is connected between the easy entry actuator and a latch member.

12. The easy entry seat assembly of claim 11 , wherein operation of the easy entry actuator moves the latch member from a locked position to an unlocked position, thereby releasing the easy entry stopper to the actuated position.

13. The easy entry seat assembly of claim 12 , wherein operation of the easy entry actuator simultaneously releases the reclining mechanism to permit pivotal movement of the backrest.

14. An easy entry seat assembly comprising:

a seat frame having a seat bottom and a backrest supported for pivotal movement relative to the seat bottom;

a reclining mechanism provided on the seat frame to selectively control pivotal movement of the backrest relative to the seat bottom; and

a backrest stopper mechanism provided on the seat frame, wherein the backrest stopper mechanism includes:

an easy entry stopper provided on a portion of the seat frame that remains generally stationary relative to the backrest, wherein the easy entry stopper is movable from a non-actuated position to an actuated position for contact with the backrest to stop pivotal movement of the backrest in an easy entry position when the reclining mechanism has been released;

a latch member provided on the seat frame, wherein the latch member is movable about a single axis relative to the seat frame between a locked position to lock the easy entry stopper in the non-actuated position and an unlocked position to release the easy entry stopper to the actuated position; and

an easy entry actuator provided on the seat frame, wherein operation of the easy entry actuator causes movement of the latch member from the locked position to the unlocked position and also releases the reclining mechanism.

15. The easy entry seat assembly of claim 14 , wherein the backrest includes a backrest stopper that is configured to contact the easy entry stopper when the easy entry stopper is in the actuated position.

16. The easy entry seat assembly of claim 14 , wherein an actuating mechanism is connected between the easy entry actuator and the latch member, and the latch member includes a connector configured to facilitate attachment of the actuating mechanism.

17. The easy entry seat assembly of claim 14 , wherein the latch member includes a hook-shaped portion configured to selectively engage the easy entry stopper.

18. The easy entry seat assembly of claim 14 , wherein the reclining mechanism includes a recliner lever, and operation of the recliner lever is configured to move the easy entry stopper from the actuated position to the non-actuated position.

19. The easy entry seat assembly of claim 18 , wherein the recliner lever includes a ramped cam surface that, upon rotation of the recliner lever, is configured to contact and move the easy entry stopper from the actuated position to the non-actuated position.

20. The easy entry seat assembly of claim 19 , wherein the easy entry stopper includes a reset pin, and the ramped cam surface is configured to contact the reset pin for movement of the easy entry stopper.
