Abstract

A vehicle headrest assembly includes a headrest member operably coupled to a seatback. The headrest member is moveable between upright and folded positions relative to the seatback. A support assembly includes first and second linkages which are pivotally coupled to the headrest member and the seatback at opposite ends thereof. First and second latch brackets are coupled to the first and second linkages respectively and operable between latched and unlatched positions for moving the headrest member to the folded position from the upright position when the latch brackets are in the unlatched position.

First claim

What is claimed is:

1. A vehicle headrest assembly comprising:
a headrest member operably coupled to a seatback between upright and folded positions;
a support assembly including first and second linkages pivotally coupled to the headrest member and the seatback at opposite ends thereof; and
first and second latch brackets coupled to the first and second linkages respectively and operable between latched and unlatched positions for moving the headrest member to the folded position from the upright position, wherein the first latch bracket is coupled to a cross member and a first actuator within the seatback, and further wherein the first actuator drives the first latch bracket vertically to move the headrest member between fore and aft positions.

2. The vehicle headrest assembly of claim 1 , wherein the first and second latch brackets each include a body portion having a slot therethrough and a latch member pivotally coupled to the body portion between latched and unlatched positions.

3. The vehicle headrest assembly of claim 2 , wherein each latch member includes a ramped portion and an engagement notch.

4. The vehicle headrest assembly of claim 3 , wherein the first linkage includes a support arm extending outwardly therefrom and coupled to the slot of the first latch bracket by a first fastener.

5. The vehicle headrest assembly of claim 4 , wherein the first fastener is retained in the engagement notch of the latch member of the first latch bracket when the latch member of the first latch bracket is in the latched position.

6. The vehicle headrest assembly of claim 5 , wherein the second linkage is coupled to the slot of the second latch bracket by a second fastener, and further wherein the second fastener is retained in the engagement notch of the latch member of the second latch bracket when the latch member of the second latch bracket is in the latched position.

7. The vehicle headrest assembly of claim 6 , the latch members of the first and second latch brackets further include handle portions for engagement by a user to move the latch members to the unlatched position from the latched position when folding the headrest member.

8. The vehicle headrest assembly of claim 7 , the latch members of the first and second latch brackets further include biasing mechanisms biasing the latch members towards the latched position.

9. A vehicle headrest assembly comprising:
a headrest member having a headrest bracket;
a seatback having a cross member with a first actuator disposed thereon;
a first linkage pivotally coupled to the cross member at a lower end and pivotally coupled to the headrest bracket at an upper end, the first linkage having a support arm extending outwardly therefrom;
a first latch bracket coupled to the first actuator, and further coupled to the support arm;
a second linkage coupled to a second latch bracket at a lower end, and pivotally coupled to the headrest bracket at an upper end, wherein the second latch bracket is disposed on the cross member, and further wherein the first and second linkages define a support assembly moveable between fore and aft positions as powered by the first actuator; and
wherein the first and second latch brackets are operable between latched and unlatched positions, and further wherein the headrest member is moveable to a folded position when the first and second latch brackets are in the unlatched position.

10. The vehicle headrest assembly of claim 9 , including:
a track assembly operably coupled to the headrest member; and
a second actuator coupled to the headrest bracket, wherein the headrest member is vertically adjustable as driven by the second actuator.

11. The vehicle headrest assembly of claim 10 , wherein the first and second latch brackets each include a body portion having a curved slot therethrough and a latch member pivotally coupled to the body portion between latched and unlatched positions.

12. The vehicle headrest assembly of claim 11 , wherein each latch member includes a ramped portion and an engagement notch.

13. The vehicle headrest assembly of claim 12 , wherein the support arm is coupled to the curved slot of the first latch bracket by a first fastener.

14. The vehicle headrest assembly of claim 13 , wherein the first fastener is retained in the engagement notch of the latch member of the first latch bracket when the latch member of the first latch bracket is in the latched position.

15. The vehicle headrest assembly of claim 14 , wherein the second linkage is coupled to the curved slot of the second latch bracket by a second fastener, and further wherein the second fastener is retained in the engagement notch of the latch member of the second latch bracket when the latch member of the second latch bracket is in the latched position.

16. A vehicle headrest assembly comprising:
a support assembly including first and second linkages pivotally coupled to a headrest member between fore and aft positions, the headrest member being vertically adjustable;
first and second latch brackets coupled to the first and second linkages respectively, the latch brackets being operable between latched and unlatched positions, wherein the headrest member is moveable to a folded position when the latch brackets are in the unlatched position;
a first actuator configured to drive the headrest member between the fore and aft positions; and
a second actuator for adjusting a vertical position of the headrest member.

17. The vehicle headrest assembly of claim 16 , wherein the first linkage includes:
a lower end pivotally coupled to a cross member disposed within a seatback to define a first lateral axis,
an upper end pivotally coupled to the headrest member to define a second lateral axis, and

wherein the second linkage includes:
an upper end pivotally coupled to the headrest member to define a third lateral axis,
a lower end pivotally coupled to the second latch bracket to define a fourth lateral axis, wherein the each of the lateral axes cooperate to maintain an angle of the headrest member as the support assembly moves between fore and aft positions.
