Abstract
A power operation system used in a chair includes a power operation system. The power operation system includes a power headrest operation system, including: a headrest board; a pair of headrest posts; a pair of headrest support posts; a headrest axis of rotation; a first mounting bracket and a second mounting bracket; a headrest actuator; a first pulling mechanism; and a first stopping mechanism. When the headrest actuator drives in the headrest forward direction, the headrest actuator rotates, through rotation of the headrest axis of rotation, the headrest board from a closed headrest position to an open headrest position. When the headrest actuator drives in the headrest backward direction, the first pulling mechanism pulls the headrest board from the open headrest position to the closed headrest position, the first stopping mechanism prevents the headrest board from rotating any further once the headrest board arrives at the closed headrest position.
