The second pillow core is located in the recess 121. The second pillowcase 21 is annular and wraps around (fits over or winds around) the upper surface, lower surface, front surface and rear surface of the first pillow body 10 (the first pillowcase 11).

[0025] In this embodiment, the front, rear, left, right, up and down are all the directions when the double-layer headrest is installed on a vertical chair back, and are only used to explain the relative position relationship between the components of the double-layer headrest in a certain specific posture. If this specific posture changes, the directional indication will also change accordingly.

[0026] See Figure 3, in this embodiment, the concave portion 121 of the first pillow core 12 serves as the limit for the second pillow core and can be referred to as the limit concave portion, that is, the structure of the first pillow core 12 around the concave portion 121 is used for the limit of the second pillow core. Usually, the concave portion 121 is a curved surface concave. In this embodiment, the first pillow core 12 only provides left and right limits for the second pillow core and penetrates through the upper and lower ends of the first pillow core 12 in the up and down direction; in another embodiment, the first pillow core 12 provides up, down, left and right limits for the second pillow core, and usually the height of the up and down limits is lower than the height of the left and right limits.

[0027] In this embodiment, the first pillow core 12 is a memory foam pillow core, for example, made of slow rebound memory foam. There is no limitation here, and the first pillow core 12 can also be made of materials such as hard cotton.

[0028] Furthermore, to improve the stability of the second pillow body 20, a first magic tape can be added. The first split body of the first magic tape is arranged on the front surface of the first pillowcase 11, corresponding to the concave portion 121. The second split body of the first magic tape is arranged on the second pillowcase 21, corresponding to the first split body. The first split body can be pasted on the second split body, and the second magic tape is located between the second pillow core and the first pillow core 12.

[0029] In this embodiment, the first pillowcase 11 and the second pillowcase 21 are fixedly connected by sewing. The upper surface of the first pillowcase 11 and the upper surface of the second pillowcase 21 are fixedly connected by sewing.

[0030] In this embodiment, the second pillowcase 21 is annular, and the second pillowcase 21 contacts (usually fits) the upper surface, lower surface, front surface and rear surface of the first pillowcase 11.

[0031] Here, the second pillowcase 21 includes a second pillow core accommodating area 211 and a second connecting belt area 212. The second pillow core accommodating area 211 and the second connecting belt area 212 are fixedly connected by sewing or are an integral structure. The second pillow core accommodating area 211 fits the front surface of the first pillowcase 11, and the second connecting belt area 212 fits the upper surface, lower surface and rear surface of the first pillowcase 11. Usually, the width of the second connecting belt area 212 is smaller than that of the second pillow core accommodating area 211.

[0032] The second pillowcase 21 can be an inseparable ring shape, and the first pillow body is compressed to put the second pillowcase 21 on the first pillow body 10. The second pillowcase 21 can also be a detachable ring shape, for example, connected by a second magic tape 2121 etc. to form a ring shape, and the second pillowcase 21 is wound around the first pillow body 10 up and down.

[0033] In this embodiment, the second pillow core includes a pillow core cover that can be opened and closed, which can be a pillow core cover with a zipper, or a pillow core cover with buttons (including male and female buttons) or other forms. The pillow core cover is filled with addable and removable filling cotton, and the addition and removal are synchronized in terms of weight and quantity, that is, a certain amount of filling cotton is added or removed. The thickness of the second pillow core is adjusted by adding or removing filling cotton in the pillow core cover. In one embodiment, the filling cotton is several groups of cotton balls, which are usually called cotton balls. It can be understood that the cotton balls are not required to be spherical. By way of example and not limitation, the filling cotton can be cashmere cotton, camel hair cotton, silk cotton, filter cotton, bamboo charcoal cotton, graphene cotton, nanofiber cotton, antibacterial cotton, Sorona's elastic cotton, etc. In another embodiment, the filling cotton is several layers of pillow core chips (sheet-shaped pillow cores). The pillow core chips can be made of memory cotton and other materials. That is, several layers of pillow core chips can be installed in the pillow core cover of the second pillow core. The several layers of pillow core chips are overlapped and placed in sequence, and the thickness can be adjusted by increasing and decreasing the total number of layers of the pillow core chips. For example, the thickness range of the pillow core chips is 0.5 cm to 3 cm.

[0034] Generally, to improve the comfort and fitting degree, the deformation degree of the second pillow core is greater than that of the first pillow core 12. Under the same acting force, the deformation of the second pillow core is greater than that of the first pillow core 12.

[0035] In this embodiment, two sets of strap mounting parts are provided on the rear surface of the first pillowcase 11. Refer to Figure 2 , and the two sets of strap mounting parts are arranged one above the other. Each set of strap mounting parts includes two strap mounting rings 111, and the two strap mounting rings 111 are arranged one on the left and the other on the right. The double-layer headrest further includes two length-adjustable socket-type binding straps. The length of the binding straps can be adjusted by a Japanese character buckle and can be tightened or loosened as needed. The two binding straps are mounted on one set of strap mounting parts. The binding straps are used to mount the double-layer headrest on the seat. Here, the binding straps can be elastic.

[0036] Here, a 9-shaped hook is sleeved on the binding strap, and the binding strap is mounted on the strap mounting ring 111 through the 9-shaped hook. An open ring, a spring lock, etc. can also be used to realize the connection between the binding strap and the strap mounting ring 111.

[0037] In an application example, the double-layer headrest is fixed on the seat by a one-word binding strap. Specifically: the two binding straps are connected into a single strap, which is called a one-word binding strap here. According to the height of the user, a set of strap mounting parts is selected. The one-word binding strap is mounted on the two strap mounting rings 111 of a set of strap mounting parts through two 9-shaped hooks on it, and the double-layer headrest is tied to the seat back by the one-word binding strap. This method is applicable to ordinary vehicle seats.

[0038] In another application example, the double-layer headrest is fixed to the seat by left and right double binding straps. Specifically: Select a set of strap mounting parts according to the user's height. One binding strap is mounted on one strap mounting ring 111 and bound to the seat; the other binding strap is mounted on the other strap mounting ring 111 and bound to the seat, that is, the two binding straps are not connected to each other. This method is applicable to the sports seats of vehicles.

[0039] It should also be noted that the double-layer headrest is not limited to the two binding straps, nor is it limited that all the straps are mounted on the same set of strap mounting parts, and even does not require that all the straps pass through the strap mounting ring 111.

[0040] It can be understood that usually the way to install the double-layer headrest on the seat is selected according to the type of seat. The seat is a vehicle seat or an office seat, etc.

[0041] The installation process of preparing a double-layer headrest with adjustable thickness and installation height is as follows: Obtain the pillowcases of the first pillowcase 11 and the second pillowcase 21. Put the first pillow core 12 into the first pillowcase 11, put an appropriate amount of filling cotton into the pillow core cover and zip it up. Put the pillow core cover into the second pillow core accommodating area 211 of the second pillowcase 21. Wrap the second pillowcase 21 around the first pillowcase 11 and fasten it by pasting the second magic tape 2121. Removably mount the binding strap on the strap mounting ring 111, and bind the double-layer headrest to the seat back by the binding strap. The user feels the thickness and position of the double-layer headrest. If the thickness is uncomfortable, remove the double-layer headrest on the seat, take out or add filling cotton to change the thickness of the double-layer headrest. If the position is uncomfortable, fine-tune the position by adjusting the tightening degree of the binding strap and / or replacing the binding strap to other sets of strap mounting parts.

[0042] As can be seen from the above detailed description of the specific embodiments of the present utility model, compared with the prior art, the present utility model designs a double-layer structure with an adjustable thickness of the second pillow core. While ensuring the basic thickness and support through the first pillow core 12, the user can adjust the thickness of the second pillow core according to the conditions of the shoulders, neck and head to improve comfort. The front surface of the first pillow core 12 of the present utility model has a recess 121, and the recess 121 runs through the upper and lower ends of the first pillow core 12. The second pillow core is located in the recess 121. With such a design, the stability of the second pillow core is improved. Through the fixed connection between the first pillowcase 11 and the second pillowcase 21, and the second pillow core is located in the recess 121, and the second pillowcase 21 wraps around the upper surface, lower surface, front surface and rear surface of the first pillowcase 11, making the double-layer headrest structure stable and not easily displaced during use. On the rear surface of the first pillowcase 11 of the present utility model, at least two groups of strap mounting parts are sequentially arranged from top to bottom. With such a design, the height of the headrest can be adjusted, which is suitable for users of different heights and can adjust the mounting height of the headrest according to the height. It can be seen that the double-layer headrest provided by the present utility model improves the applicable range and use comfort of the headrest.
