Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, the headrest lining structure in this embodiment includes a central body 1, wherein two side wings 2 are disposed on two sides of the central body 1, when the position of the headrest lining structure is adjusted by using an adjusting assembly as described in the background art, the side wings 2 deflect relative to the central body 1 to support the rear side of the head, the central body 1 and the side wings 2 are connected by a freely deformable bladder 3, which is generally a liquid bladder, preferably a liquid bladder filled with colloidal liquid, the side wings 2 are limited to rotate in a limited manner with the center of the bladder 3 as a rotation center, and the rotation extrusion causes the bladder 3 to deform to fill a gap between the main body and the side wings 2.
