Abstract

A vehicle seat is provided herein. The vehicle seat includes a seatback pivotally coupled to a seat bottom. An adjustment assembly is operably coupled with the seat and includes a linear actuator. The linear actuator is configured to release a recliner mechanism when moved in a first direction and is configured to release a track assembly when moved in a second direction.

Claims

1. A vehicle seat comprising:

a seatback pivotally coupled to a seat bottom; and

an adjustment assembly operably coupled with the seat and including a linear actuator, the linear actuator configured to release a recliner mechanism when moved in a first direction and configured to release a track assembly when moved in a second direction.

2. The vehicle seat of claim 1, wherein the linear actuator is configured as a rack and a pinion, the pinion driven by a motor.

3. The vehicle seat of claim 1, wherein the recliner mechanism includes a shaft extending between a pair of recliner hearts.

4. The vehicle seat of claim 1, wherein the adjustment assembly is operably coupled with the recliner mechanism via a wire, the linear actuator configured to pull the recliner arm generating a force on the wire to rotate a first portion of the recliner mechanism relative a second portion of the recliner mechanism to release the seatback.

5. The vehicle seat of claim 1, further comprising:

a first switch electrically coupled to the adjustment assembly for moving the linear actuator in a first direction; and

a second switch electrically coupled to the adjustment assembly for moving the linear actuator in a second direction.

6. The vehicle seat of claim 5, further comprising:

a third switch coupled to the adjustment assembly configured to move the linear actuator in a first direction to release the recliner mechanism and then move the linear actuator in a second direction to release the track assembly.

7. The vehicle seat of claim 2, wherein the rack defines a pinion cavity, first and second channels, and first and second guides, the first channel and first guide disposed on an opposing side of the pinion cavity from the second channel and second guide.

8. The vehicle seat of claim 7, wherein a recliner arm is disposed within the first channel and a first pin is operably coupled with the recliner arm, the first pin extending into the first guide.

9. The vehicle seat of claim 8, wherein a track assembly arm is disposed within the second channel and a second pin is operably coupled with a track assembly arm, the second pin extending into the second guide.

10. The vehicle seat of claim 8, wherein the rack is configured to linearly move in a first direction causing the first pin to contact an end portion of the first guide thereby pulling the recliner arm in the first direction.

11. The vehicle seat of claim 10, wherein the rack is configured to linearly move in a second direction causing a second pin to contact an end portion of the second guide thereby pulling the track assembly arm in the second direction.

12. The vehicle seat of claim 1, further comprising:

a pivot assembly including a first portion coupled with a recliner arm second portion having a coupling portion for removably fixing a wire thereto, wherein the wire is operably coupled with the recliner mechanism.

13. A vehicle seat comprising:

a seatback pivotally coupled to a seat bottom;

an adjustment assembly operably coupled with the seat and configured to pull a recliner arm when moved in a first direction and a track assembly arm when moved in a second direction;

a wire operably coupled with the recliner arm and a recliner mechanism to release the seatback relative the seat bottom; and

a disengagement rod operably coupled with the track assembly arm.

14. The vehicle seat of claim 13, wherein the seatback is locked relative the seat bottom and the track assembly is locked relative a vehicle floor in a neutral position.

15. The vehicle seat of claim 13, wherein the adjustment assembly includes a rack that defines a pinion cavity, first and second channels, and first and second guides, the first channel and first guide disposed on an opposing side of the pinion cavity from the second channel and second guide.

16. The vehicle seat of claim 15, wherein the rack is configured to linearly move in a first direction causing a first pin to contact an end portion of the first guide thereby pulling the recliner arm in the first direction and to linearly move in a second direction causing a second pin to contact an end portion of the second guide thereby pulling the track assembly arm in the second direction.

17. A vehicle seat comprising:

a seatback pivotally coupled to a seat bottom; and

an adjustment assembly including a rack and a pinion configured to release a first feature and a second feature when the rack is moved in first and second directions, wherein the rack defines a pinion cavity and first and second guides, the first guide disposed on an opposing side of the pinion cavity from the second guide.

18. The vehicle seat of claim 17, wherein a recliner arm is disposed within a first channel and a first pin is operably coupled with a recliner arm, the first pin extending into the first guide.

19. The vehicle seat of claim 18, wherein a track assembly arm is disposed within a second channel and a second pin is operably coupled with a track assembly arm, the second pin extending into the second guide.

20. The vehicle seat of claim 19, wherein the rack is configured to linearly move in the first direction causing the first pin to contact an end portion of the first guide thereby pulling the recliner arm in the first direction and in a second direction causing the second pin to contact an end portion of the second guide thereby pulling the track assembly arm in the second direction.
