For seats, such as automobile seats, because passengers have different height and sitting posture, in order to adapt to the needs of different passengers, headrest needs to be set to be height-adjustable. The inventor of the present disclosure found that the structure of the current seat headrest height-adjustable mechanism generally needs to be integrated into the headrest rod type headrest. However, for non-headrest rod-type headrest structures, height-adjustable movable headrest modules generally have a complex structure, many parts, and occupy a large space, resulting in a complicated assembly process of the seat and inconvenient disassembly and assembly.

The inventor has found that structure of current headrest height-adjustable mechanism generally needs to be integrated into headrest with headrest rod. For headrest without headrest rod, structure of the height-adjustable headrest mechanism is complex, and has many parts, and occupies large space, resulting in a complicated assembly process of the seat and inconvenient disassembly and assembly.

After in-depth research, the inventors of the present disclosure provide a movable headrest module to solve the above problems.
