Abstract

A headrest assembly includes a headrest bun adjustably supported on a linkage system. An adjustable cover assembly is operable between stowed and deployed positons relative to a position of the headrest bun and is configured to cover the linkage system in use. The adjustable cover assembly includes first and second members, wherein the first member is coupled to the linkage system for movement therewith and the second member is pivotally coupled to the first member. A gap is defined between the first member and the second member, and the gap is maintained by a plurality of spacers disposed on the first member as the cover assembly moves from the stowed position to the deployed position with the headrest bun.

First claim

We claim:

1. A headrest assembly, comprising:
a headrest bun adjustably supported on a linkage system;
a cover assembly having a first member coupled to the linkage system and a second member coupled to the first member, wherein the first member is telescopingly received in the second member; and
a gap defined and maintained between the first and second members as the cover assembly moves between stowed and deployed positions as driven by the linkage system.

2. The headrest assembly of claim 1 , wherein the first member is coupled to the linkage system at an inner surface of the first member.

3. The headrest assembly of claim 2 , wherein the second member is pivotally coupled to the first member.

4. The headrest assembly of claim 3 , wherein the second member is operable between upright and rearwardly tilted positions.

5. The headrest assembly of claim 1 , wherein the first member includes first and second side portions that are spaced apart and a top portion interconnecting the first and second side portions.

6. The headrest assembly of claim 5 , wherein the second member includes first and second side portions that are spaced apart and a top portion interconnecting the first and second side portions.

7. The headrest assembly of claim 6 , wherein the top portion of the first member includes one or more spacers outwardly extending from an outer surface thereof.

8. The headrest assembly of claim 7 , wherein the first and second side portions of the first member each include one or more spacers outwardly extending from outer surfaces thereof.

9. The headrest assembly of claim 8 , including:
an interior rim extending along the top portion and first and second side portions of the second member on an inner surface thereof.

10. The headrest assembly of claim 9 , wherein the one or more spacers of the top portion of the first member engage a portion of the interior rim disposed on the top portion of the second member as the first member moves from a nested position within an interior of the second member to an outwardly extended position.

11. The headrest assembly of claim 10 , wherein the one or more spacers of the first and second side portions of the first member engage portions of the interior rim disposed on the first and second side portions of the second member as the first member moves from a nested position within an interior of the second member to an outwardly extended position.

12. The headrest assembly of claim 11 , wherein the one or more spacers disposed on the top portion and first and second side portions of the first member are configured to maintain the gap between the first member and second member of the cover assembly.

13. A headrest assembly, comprising:
a housing;
a linkage system operable between fore and aft positions relative to the housing; and
a cover assembly operable between stowed and deployed positions, the cover assembly including a first member coupled to the linkage system for movement therewith, and a second member coupled to the first member, wherein the first member is partially received within the second member when the cover assembly is in the stowed position.

14. The headrest assembly of claim 13 , including:
a gap defined between the first member and the second member, wherein the gap defines a clearing distance between the first member and the second member that is maintained between the first member and the second member as the cover assembly moves between the stowed and deployed positions.

15. The headrest assembly of claim 14 , wherein the first member includes a plurality of spacers disposed on an outer surface thereof, the plurality of spacers configured to engage an upper portion of the second member for carrying the upper portion of the second member forward as the cover assembly moves from the stowed position to the deployed position.

16. The headrest assembly of claim 13 , wherein the cover assembly is driven to the deployed position as the linkage system moves to the fore position.

17. The headrest assembly of claim 13 , wherein an upper portion of the first member of the cover assembly extends outwardly relative to an upper portion of the second member when the cover assembly moves from the stowed position to the deployed position.

18. A headrest assembly, comprising:
a cover assembly operable between stowed and deployed positions and configured to partially cover a linkage system, the cover assembly including first and second members, wherein the first member is coupled to the linkage system for movement therewith; and
a plurality of spacers disposed along an outer surface of the first member, wherein the spacers are configured to engage an inner surface of the second member as the linkage system moves towards a fore position from an aft position.

19. The headrest assembly of claim 18 , wherein the first member is in a partially nested position within an interior of the second member when the cover assembly is in the stowed position, and further wherein the first member moves outwardly from the partially nested position when the cover assembly moves from the stowed position to the deployed position.

20. The headrest assembly of claim 18 , including:
a gap defined between the first member and the second member, wherein the gap defines a clearing distance between the first member and the second member that is maintained by the plurality of spacers between the first member and the second member as the cover assembly moves to the deployed position from the stowed position.
