The vehicle seat assembly also includes at least one first linkage that is moveably connected to the seatback frame, is operatively connected to the upper armature, and is operatively connected to the lower armature. The vehicle seat assembly further includes at least one second linkage that is moveably connected to the seatback frame and is operatively connected to the lower armature. The lower armature is operable to concurrently move each of the first linkage and the second linkage relative to the seatback frame in response to a predetermined force applied to the lower armature to thereby move the upper armature and move the head restraint toward the occupant.
