A foldable seat headrest assembly including a locking mechanism that includes a lock lever that can be manipulated by a manual release handle that selectively locks the headrest pad component against a groove formed in a portion of a lock post so as to keep the headrest assembly in an upright position. The groove provides both a back stop and a forward stop for the lock lever. When the lock lever is disengaged from the groove by manipulating the release handle in a downward motion, a dump spring allows the headrest portion to assume a folded or dumped position. In the folded or dumped position, the headrest portion fits compactly against the back portion of the seat. The manual release handle can be associated with either the left or the right side of the headrest assembly allowing the same assembly to be used on either side of a vehicle, e.g., the driver or passenger side of the vehicle, as well in the front and rear seats.

1. A foldable headrest assembly for a seat, comprising: a plate member extending from a distal end to a support end;a seat frame member including a paddle member, said plate member being rotatably supported by said paddle member for rotation about an axis for movement between an upright and a forwardly folded position;wherein said paddle member includes a groove formed therein, wherein said groove includes a first stop surface and a second stop surface; anda latch lever member rotatably supported on one of said plate member and said paddle member for movement between a latched position engaging said groove of said paddle member for preventing folding movement from said upright position toward said forwardly folded position and for movement of said latch lever member to disengage said groove of said paddle member to an unlatched position allowing such folding movement;wherein the latch lever member and the groove are configured such that the latch lever member contacts both the first stop surface and the second stop surface simultaneously when the latch lever member is in the latched position; andwherein the first stop surface and the second stop surface are substantially parallel to one another. 2. The invention according to claim 1, further comprising: a first support member extending from a first distal end to a first support end; anda second support member spaced from said first support member and extending from a second distal end to a second support end for supporting a headrest between said support ends. 3. The invention according to claim 2, further comprising a second plate member extending from said second distal end. 4. The invention according to claim 3, wherein said seat frame member further comprises a second paddle member spaced from said paddle member, said first plate member being rotatably supported by said first paddle member for rotation about an axis, said second plate member being rotatably supported by said second paddle member on said axis for movement in unison with said first plate member between an upright and a forwardly folded position. 5. The invention according to claim 4, further comprising a shaft member extending between and supported by said paddle member and said second paddle member on said axis. 6. The invention according to claim 5, wherein said shaft member includes an ear portion extending from said shaft member in a transverse direction to said axis and said ear portion defines an aperture. 7. The invention according to claim 6, wherein said release member includes a latch handle extending between and rotatably supported by one of said plate member and said rod member. 8. The invention according to claim 7, further comprising a second rod member spaced from and parallel to said rod member, wherein said second end of said biasable member engages said second rod member for biasing said plate member and said second plate member toward said forwardly folded position. 9. The invention according to claim 8, further comprising a second biasable member having a first end and a second end, said second biasable member reacting between said rod member and said second rod member, wherein said second end engages said second rod member for biasing said plate member and said second plate member toward said forwardly folded position. 10. The invention according to claim 6, further comprising a rod member connected to and extending between said plate member and said second plate member, wherein said rod member is spaced apart from and parallel to said shaft member. 11. The invention according to claim 10, further comprising a biasable member having a first end and a second end, wherein said first end engages through said aperture of said ear portion and said second end engages said rod member for biasing said plate member and said second plate member toward said forwardly folded position. 12. The invention according to claim 1, further comprising a release member for selectively rotating said latch lever member to said unlatched position allowing said plate member to rotate about said axis to said forwardly folded position. 13. The invention according to claim 1, wherein said latch lever member is generally L-shaped and said groove defines a generally C-shaped pocket for receiving at least a portion of said latch lever member. 14. A foldable headrest assembly for a seat, comprising: a support member extending from a distal end to a support end;a plate member extending from said distal end;a seat frame member including a paddle member, said plate member being rotatably supported by said paddle member for rotation about an axis for movement between an upright and a forwardly folded position;wherein said paddle member includes a groove formed therein, wherein said groove includes a first stop surface and a second stop surface; anda latch lever member rotatably supported on one of said plate member and said paddle member for movement between a latched position engaging said groove of said paddle member for preventing folding movement from said upright position toward said forwardly folded position and for movement of said latch lever member to disengage said groove of said paddle member to an unlatched position allowing such folding movement;wherein the latch lever member and the groove are configured such that the latch lever member contacts both the first stop surface and the second stop surface simultaneously when the latch lever member is in the latched position; andwherein the first stop surface and the second stop surface are substantially parallel to one another. 15. The invention according to claim 14, further comprising a second support member spaced from said support member and extending from a second distal end to a second support end for supporting a headrest between said support ends. 16. The invention according to claim 15, further comprising a second plate member extending from said second distal end. 17. The invention according to claim 16, wherein said seat frame member further comprises a second paddle member spaced from said paddle member, said first plate member being rotatably supported by said first paddle member for rotation about an axis, said second plate member being rotatably supported by said second paddle member on said axis for movement in unison with said first plate member between an upright and a forwardly folded position. 18.
