A headrest assembly having a bracket mount affixed to an upper portion of a seatback frame and at least one headrest bun supporting tube pivotally secured to the bracket mount. A spring biased cam is pivotally secured to the bracket mount and, in a normally biased position, engages an underside projection of a selected one of the supporting tubes, the cam also having an outwardly projecting pin. At least one wheel shaped component is rotatably mounted to an exterior of the bracket mount in proximity to the cam, the wheel having an outer circumferential location which, upon being rotated, contacts the projecting pin causing the cam to pivot in a downward unseating direction from the supporting tube, triggering release of the headrest and supporting tubes in a forwardly rotating and dump position.
