The terminology used in the description of the present application is for the purpose of describing particular embodiments only and is not intended to limit the present application. The term "and / or" used in the present application includes any and all combinations of one or more of the associated listed items.

[0035] Reference will now be made to Figures 1 to 3The vehicle seat headrest 100 provided by the application comprises a cover 10, a first chamber 11 arranged in the cover 10, and a foamed filling piece 20 filled in the first chamber 11; the vehicle seat headrest 100 further comprises a barrier film layer 30 and a flexible layer 40, the barrier film layer 30 is arranged between the cover 10 and the foamed filling piece 20, and the flexible layer 40 is arranged between the barrier film layer 30 and the cover 10. It needs to be explained that the headrest commonly used in the vehicle seat at present is generally a PIP headrest, which is made by filling the foamed material in the cover after the cover is combined with the barrier film. However, when the foamed material is filled in the cover, the inside of the cover is expanded and even exuded to the inside or the outer surface of the cover, so that the overall hardness of the cover is too high, thereby affecting the comfort of the headrest. Therefore, the barrier film layer 30 and the flexible layer 40 are arranged in the application, the barrier film layer 30 can prevent the foamed filling piece 20 from exuding, and when the foamed filling piece 20 is filled in the cover 10 and the barrier film layer 30, only the inside of the barrier film layer 30 is expanded, and the expansion degree of the outer cover 10 is not affected; meanwhile, the flexible layer 40 is arranged between the barrier film layer 30 and the cover 10, the cover 10 and the barrier film layer 30 are separated by the flexible layer 40, and the softness of the outer surface of the cover 10 is improved by the flexible layer 40, thereby improving the comfort of the vehicle seat headrest 100.

[0036] Here, the cover 10 comprises a plurality of pieces of material 12, which are spliced and surrounded with each other to form the first chamber 11. In this way, the vehicle seat headrest 100 is convenient to disassemble and maintain.

[0037] Further, the cover 10 is arranged as one of a leather cover and a fabric cover or is spliced from the two, and the specific arrangement can be selected by the user according to the own needs.

[0038] As preferred, a leaning part 13 is formed on the surface of the cover 10, the leaning part 13 is used for the head to lean on, and the flexible layer 40 is arranged at the position of the leaning part 13, so as to improve the hardness of the leaning part 13 by the flexible layer 40, so that the leaning part 13 is relatively soft, and the comfort and satisfaction of the user when using the vehicle seat headrest 100 are improved. Meanwhile, the leaning part 13 is used for the head to lean on, and other positions are not required to be so soft. Therefore, the flexible layer 40 is arranged at the position of the leaning part 13, so as to save the production cost of the vehicle seat headrest 100, thereby improving the performance-price ratio of the product.

[0039] As Figure 2 and Figure 3As shown, the face cover 10 includes a first layer 14 and a second layer 15, the first layer 14 surrounds the first chamber 11, the second layer 15 is arranged in the first chamber 11 and located at the position of the abutting part 13, the second layer 15 is connected with the first layer 14 and surrounds the second chamber 16; wherein the first chamber 11 and the second chamber 16 are separated by the second layer 15. In this way, the foamed filling piece 20 can be separated by the second layer after being filled into the first chamber 11, thereby avoiding the foamed filling piece 20 causing the outer surface of the face cover 10 to be tight, affecting the comfort of the user during use.

[0040] Here, the first layer 14 and the second layer 15 are connected by thread sewing. The first layer 14 and the second layer 15 are connected by thread sewing, which is simple and easy to maintain and repair. Not limited to this, the first layer 14 and the second layer 15 can also be connected by glue or other means.

[0041] Please continue to refer to Figure 2 and Figure 3 , the impermeable film layer 30 and the flexible layer 40 are arranged in the second chamber 16, that is, they are located between the first layer 14 and the second layer 15 of the face cover 10, and at the same time, the flexible layer 40 is arranged between the impermeable film layer 30 and the first layer 14. In this way, the position where the abutting part 13 of the vehicle seat headrest 100 is located is composed of the first layer 14, the flexible layer 40, the impermeable film layer 30, the second layer 15 and the foamed filling piece 20 in turn, and such a setting mode can effectively isolate the hardness of the foamed filling piece 20 in the second layer 15 and the impermeable film layer 30, and further reduce the hardness of the vehicle seat headrest 100 through the setting of the flexible layer 40, thereby improving the overall use comfort of the headrest.

[0042] Here, the impermeable film layer 30 is configured as any one of a non-woven composite impermeable film layer, a polyvinyl chloride film layer, and a high-density polyethylene film layer. Of course, it is not limited to this, and other impermeable materials can also be selected according to needs. Here, the non-woven composite impermeable film layer, the polyvinyl chloride film layer, and the high-density polyethylene film layer can all effectively prevent the foamed filling piece 20 from leaking out and improve the softness of the outer surface of the face cover 10.

[0043] The flexible layer 40 is configured as one or more spliced layers of sponge layer, silica gel layer, and cotton layer. Of course, it is not limited to this, and other materials can also be selected according to needs. Here, the sponge layer, the silica gel layer, and the cotton layer all have good flexibility and comfort, which can adapt to different shapes and pressures and effectively improve the user's experience.

[0044] As Figure 2As shown, the vehicle seat headrest 100 further comprises a reinforcing seat 50, which is arranged in the first cavity 11. It can be understood that, by arranging the reinforcing seat 50 in the first cavity 11, the vehicle seat headrest 100 can always maintain a certain shape and provide support to the head without affecting the comfort of the user.

[0045] Here, the reinforcing seat 50 is made of foamed polypropylene, i.e., EPP material. The EPP material has the characteristics of durability, difficulty in deformation, and light weight, and can reduce the overall weight of the vehicle seat headrest 100 while ensuring the shape and durability of the reinforcing seat 50, thereby improving the performance of the product.

[0046] The application also provides a vehicle seat comprising the vehicle seat headrest 100 described in any of the above embodiments.

[0047] Further, the application also provides a vehicle comprising the vehicle seat described in the above embodiments.

[0048] The technical features of the above embodiments can be combined in any manner. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present application.

[0049] The above embodiments only express several implementation manners of the application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be pointed out that, for those skilled in the art, without departing from the concept of the application, a number of modifications and improvements can be made, which are all within the protection scope of the application.
