The invention discloses a folding device for a seat headrest framework. The folding device comprises a headrest rod, a headrest bracket, a folding rotating shaft, a fixing plate, a folding button, a headrest base framework, an unlocking bracket, a locking plate, an unlocking rotating shaft and a linking pin. When the folding button is pressed, a button return spring is pressed by the folding button, the unlocking bracket is driven to rotate around an axis of a mounting pillar under the driving of an end of the folding button, an acting force is also applied to an unlocking bracket return spring, and meanwhile, the linking pin is driven to upward move along a bar-shaped slot by an unlocking stirring plate, the linking pin drives the locking plate to rotate around a locking rotating shaft and applies an acting force to a locking plate return spring, and lastly, a locking part of the locking plate quits from a locking notch of the fixing plate, so that the unlocking is realized, and meanwhile, the headrest bracket can rotate around the folding rotating shaft under an effect of an external force so that the folding of the headrest framework is realized. The folding device for the seat headrest framework has the advantages of simple structure, few parts, compact structure and low manufacturing cost.
