Abstract

A headrest assembly includes a linkage system with a first adjustment mechanism configured to power fore and aft movement of a mounting plate. A headrest bun is slideably coupled to the mounting plate and is vertically adjustable via a second adjustment mechanism. A telescoping cover assembly is operable between stowed and deployed positions and configured to substantially conceal the linkage system as the linkage system moves between extended and retracted positions. A disconnect clip includes a first portion disposed on one or more support posts configured to support the headrest assembly, and a second portion disposed on the seatback frame. Power is provided to the first and second adjustment mechanisms when the first portion of the disconnect clip is electrically coupled to the second portion of the disconnect clip.

First claim

What is claimed is:

1. A vehicle seat, comprising:
a seatback having a seatback frame;
one or more support posts removeably received in a portion of the seatback frame;
a headrest assembly supported on the one or more support posts, the headrest assembly comprising:
a linkage system including a mounting plate;
a first adjustment mechanism coupled to the linkage system for driving the linkage system between extended and retracted positions;
a second adjustment mechanism coupled to the mounting plate and further coupled to a headrest bun through an access aperture disposed through the mounting plate, wherein the second adjustment mechanism drives the headrest bun between raised and lowered positions relative to the mounting plate; and

a power clip assembly having a first portion disposed on the one or more support posts and a second portion disposed on the seatback frame, wherein power is provided to the first and second adjustment mechanisms when the first portion of the power clip assembly is electrically coupled to the second portion of the power clip assembly.

2. The vehicle seat of claim 1 , including:
a telescoping cover assembly operable between stowed and deployed positions and configured to substantially conceal the linkage system as the linkage system moves between the extended and retracted positions.

3. The vehicle seat of claim 2 , wherein the telescoping cover assembly includes a first portion and a second portion, and further wherein the first portion extends outwardly from the second portion in the deployed position and the first portion is partially nested with the second portion when the telescoping cover is in the stowed position.

4. The vehicle seat of claim 1 , wherein one of the first portion, the second portion and both the first and second portions of the power clip assembly include a guide sleeve configured to receive the one or more support posts of the headrest assembly.

5. The vehicle seat of claim 4 , wherein the first portion of the power clip assembly includes a power plug and further wherein the second portion of the power clip assembly includes a receptacle configured to receive the power plug in a connected configuration.

6. The vehicle seat of claim 1 , wherein the one or more support posts include first and second support posts having first and second locking mechanisms disposed on the seatback frame associated therewith, the first and second locking mechanisms configured to retain the first and second support posts on the seatback frame when the headrest assembly is received on the seatback frame.

7. The vehicle seat of claim 6 , wherein the first and second locking mechanisms each include release tabs operably coupled thereto and configured to release the locking mechanisms from a locked condition to remove the headrest assembly from the seatback frame.

8. The vehicle seat of claim 1 , wherein the linkage system further includes a base plate and first and second links, wherein the first and second links pivotally interconnect the mounting plate and the base plate.

9. The vehicle seat of claim 8 , wherein the adjustment mechanism is pivotally coupled to the base plate and the second link.

10. A headrest assembly, comprising:
a linkage system having a first adjustment mechanism for powering fore and aft movement of a mounting plate;
a headrest bun having a support plate slideably coupled to the mounting plate; and
a second adjustment mechanism operably coupled between the mounting plate and the headrest bun through an access aperture disposed through the mounting plate for powering vertical movement of the headrest bun relative to the mounting plate.

11. The headrest assembly of claim 10 , wherein the support plate of the headrest bun is slideably coupled to the mounting plate by a rail and channel arrangement.

12. The headrest assembly of claim 11 , wherein the mounting plate includes first and second sides and further wherein the first side of the mounting plate includes first and second channels coupled thereto on opposite sides of the access aperture.

13. The headrest assembly of claim 12 , wherein the support plate includes first and second sides and further wherein the second side of the support plate includes first and second rails coupled thereto and configured to be slideably received in the first and second channels of the mounting plate.

14. The headrest assembly of claim 13 , including:
a rear trim cover, and
a telescoping cover assembly having first and second portions, the telescoping cover assembly operable between stowed and deployed positions relative to the fore and aft movement of the linkage system, wherein the first portion of the cover assembly is coupled to the second side of the mounting plate, and further wherein the second portion of the cover assembly is operably coupled to the rear trim cover.

15. A headrest assembly, comprising: a linkage system comprising a base plate and a mounting plate pivotally interconnected by first and second links; an actuator operably coupled to the linkage system for translating the linkage system between extended and retracted positions; and a cover assembly operable between stowed and deployed positions and having a first portion that is partially nested within a second portion when the cover assembly is in a stowed position, wherein the actuator is a linear actuator pivotally coupled between the base plate and one of the first and second links, wherein the actuator includes a threaded member having a mounting tab disposed thereon which is pivotally coupled to the second link.

16. The headrest assembly of claim 15 , wherein the actuator pivots independently of one or more pivot axes of the linkage system when driving the linkage system between extended and retracted positions.

17. The headrest assembly of claim 15 wherein the first portion extends outwardly from the second portion in the deployed position.

18. The headrest assembly of claim 17 , including:
a headrest bun slideably coupled to a first side of the mounting plate, wherein the front portion of the cover assembly is coupled to a second side of the mounting plate.
