A vehicle seat assembly comprising:

• a generally horizontal seat cushion having a rear end;
• a seat back including a backrest with lower and upper ends having a use position extending upwardly from the rear end of the seat and against which a seat occupant rests their torso, the seat back further including a headrest mounted at the upper end of the backrest, the headrest having a use position extending upwardly from the upper end of the backrest, the backrest being movable from its use position to a stored position;
• means for vertically adjusting the use position of the headrest relative to the backrest;
• a releasable seat back latch for holding the backrest in its upwardly extending use position;
• the headrest being movable mounted to the backrest for movement relative to the backrest from its upwardly extending use position to a lower stored position;
• and
• releasable coupling means operably associated with the headrest and the seat back latch for coupling the headrest to the seat back latch and for releasing the seat back latch in response to movement of the headrest from its use position to its stored position, the coupling means being released when the headrest is vertically moved above its lowermost vertical position and only being coupled when the headrest is in the lowermost vertical position relative to the backrest whereby the seat back latch is released upon movement of the headrest to its stored position to enable the seat back to be moved to its stored position.
