Convenient-to-fold headrest framework mechanism

The utility model discloses a convenient-to-fold headrest framework mechanism which 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 linkage pin, wherein when the folding button is pressed, the folding button compresses a button resetting spring; the end socket of the folding button pushes the unlocking bracket to rotate around the axial line of a mounting column and applies an acting force to an unlocking bracket resetting spring; meanwhile, an unlocking shifting plate pushes the linkage pin to upwards move along a strip-type slot; the linkage pin drives the locking plate to rotate around an unlocking rotating shaft and applies acting force to a locking plate resetting spring to finally enable the locking part of the locking plate to be separated from a locking gap of the fixing plate, and unlocking is realized; at the moment, under the action of the outer force, the headrest bracket can rotate around the folding rotating shaft to realize folding of the headrest framework. The convenient-to-fold headrest framework mechanism is simple and compact in structure and low in manufacturing cost, and the quantity of parts is small.
