This invention can electrically drive the headrest to adjust its angle and position using an electric push rod. The upper crossbeam 23 is connected to the linkage rod 16, while the lower crossbeam 24 is generally fixed. During the upward movement of the upper crossbeam 23, since the linkage rod 16 and the top rod 151 are roughly parallel to the connection section of the upper and lower swing rods 14, the amplitude of the back-and-forth swing during the movement is relatively small. This also minimizes the amount of time the upper crossbeam 23 may flip during the movement, which helps to increase the stability of the structure.

[0046] In summary, the upper part of this utility model can be exposed, and the headrest of the sofa seat is installed through the headrest fixing seat. The up and down swing of the upper and lower swing rods realizes the raising and lowering of the top rod, thereby adjusting the position of the headrest fixing component on the top rod. The headrest of the sofa seat can also be detachably connected to the main body of the sofa seat through the headrest fixing seat, which can realize quick assembly and disassembly of the headrest. Furthermore, the space occupied by the raising and lowering adjustment of the top rod of this utility model is small, which is conducive to the thinning of the backrest. The rotating rod of this utility model is arranged adjacent to the top rod. During the movement, the rotating rod and the top rod maintain a basically vertical posture. During the rotation, the top rod raises or lowers the headrest fixing seat, while the rotating rod drives the headrest fixing seat to rotate, so that the angle can be adjusted simultaneously during the raising and lowering of the headrest. In addition, the curved rod of this utility model can be clamped inward when the top rod and the rotating rod rise, which helps to reduce the space occupied and thus facilitates the thinning of the backrest.

[0047] Furthermore, this invention can electrically drive the headrest to adjust its angle and position using an electric push rod. The upper crossbeam of this invention is connected to the linkage rod, while the lower crossbeam is generally fixed. During the upward movement of the upper crossbeam, since the connection between the linkage rod and the top rod is roughly parallel to the upper and lower swing rods, the amplitude of the back-and-forth swing during the movement is relatively small, which also minimizes the extent of the upper crossbeam's flipping during the movement, thus increasing the stability of the structure.

[0048] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
