At this time, if there is an obstacle between the headrest 20 and the backrest 10, the headrest 20 is stopped, the restoring force of the spring does not push the sliding assembly 400 and the first slider 610 to move downward, the motor pushes the second slider 620 to move downward, the first slider 610 and the second slider 620 are separated from each other, and the torque output by the motor does not cause pressure on the obstacle. So both protected the motor, importantly, when the barrier is the human body, protected the user not to be hurt. If there is no obstacle, the headrest 20 moves downward until it abuts against the backrest 10, or reaches a preset position.
To sum up, the headrest adjusting device and sofa thereof that this application provided, compare current headrest adjusting device and the advantage lies in: the elastic component and other structures are ingeniously arranged, so that a user is prevented from being injured by the extrusion of the headrest and the backrest when using the headrest adjusting device, and the headrest adjusting device is simple in structure and easy to maintain and popularize.
