DETAILED DESCRIPTION OF THE INVENTION

[0018] The following clearly and completely describes the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments, and all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without any creative efforts are all within the protection scope of the present invention.

[0019] As shown in Figures 1 to 5, the height-adjustable back support pillow includes a back support section 2 and a head support section 3, the head support section 3 has a first neck lifting structure 31 and a second neck lifting structure 32, an arc-shaped recess 33 is formed between the first neck lifting structure 31 and the second neck lifting structure 32, and the thickness X at the position of the first neck lifting structure 31 is greater than the thickness Y at the position of the second neck lifting structure 32, and the back support section 2 can be installed on the side adjacent to the first neck lifting structure 31 or the side adjacent to the second neck lifting structure 32.

[0020] In this application, the user can first freely choose either the first neck lifting structure 31 or the second neck lifting structure 32 as support for the neck, the arc-shaped recess 33 corresponds to the position of the back of the head, the back support part 2 can be placed on either side of the head support part 3, it can adapt to different physiological curvatures of the cervical vertebrae, the support is more fitting and comfortable, by changing the position of the back support part 2 it can indirectly adapt to different people, it forms three-point support for the head, neck and back, and improves comfort during sleep.

[0021] The top ends of the first neck lifting structure 31 and the second neck lifting structure 32 are arc surface structures.

[0022] Specifically, as shown in FIGS. 1 to 5 and 8, the thickness of the back support portion 2 gradually decreases in the direction from the head support portion 3 to the direction away from the head support portion 3.

[0023] The gradually changing thickness design fits the physiological curvature of the human back, becoming gradually thinner from the head support section 3 outwards, allowing for a natural fit from the upper back to the lumbar junction, avoiding localized floating and providing more uniform support.

[0024] Furthermore, as shown in FIGS. 1, 6 and 7, the thickness of the back support part 2 gradually decreases from the center C of the back support part 2 toward both sides of the back support part 2.

[0025] The design, which is thick in the middle and gradually thins towards the sides, can adapt to the position of the spine and the muscles on both sides of the back when lying on your back, lifting the middle and creating a supportive effect that fits both sides, avoiding localized lifting or pressure on the back.

[0026] As shown in FIG. 7, the upper surface of the back support part 2 forms an arc-shaped curved surface.

[0027] Specifically, as shown in FIGS. 1 to 6 and 8, the back support portion 2 has an inclined portion 21, which is located at one end of the back support portion 2 away from the head support portion 3.

[0028] The design of the inclined portion 21 away from the head support portion 3 forms a smoothly continuing support gradient, avoiding the appearance of a sharp edge at the end of the back support portion 2. The inclined portion 21 can adapt to the natural engagement angle between the back and the bed surface, making the support curve from the upper back to the lumbar region smoother, and avoiding discomfort caused by the end of the support portion being too hard or too thick.

[0029] Specifically, the head support part 3 and the back support part 2 are connected by a detachable structure.

[0030] The detachable structure allows the head support part 3 and the back support part 2 to be flexibly disassembled, and they can be used in combination to achieve coordinated support for the head and back, or the head support part 3 can be used alone to adapt to different usage scenarios.

[0031] Disassembly makes cleaning and maintenance easy, and the head support part 3 or back support part 2, which are prone to getting dirty, can be washed separately and dried in the sun. After being connected, it is also possible to prevent the head support part 3 and back support part 2 from separating.

[0032] Specifically, the detachable structure is a zipper structure.

[0033] The zipper structure is easy and intuitive to operate, opens and closes smoothly, and allows for quick combination or disassembly of the head support part 3 and the back support part 2 without requiring complicated steps. Specifically, the zipper structure includes two first element parts, one second element part, and a slider, and the first element parts are sewn to both ends of the head support part 3, the second element part that fits with the first element parts is sewn to the back support part 2, and the slider is attached to the second element part, so that the position of the back support part 2 can be easily changed at any time on both sides of the head support part 3, and the back support part 2 can be selectively connected to either side.

[0034] In this application, due to the general nature of fastener structures, the fastener structures are not shown in the drawings.

[0035] Specifically, as shown in Figures 1 to 4, it further includes at least one height adjustment unit 4, which is detachably installed below the head support unit 3 to change the height of the head support unit 3.

[0036] By adding the height adjustment part 4, the height of the head support part 3 can be adjusted to suit different heights, usage scenes or needs. The height of the head support part 3 can be adapted to the actual usage needs, and by designing it to be detachable, it can be removed when the height is not to be adjusted.

[0037] Specifically, the head support part 3 and the height adjustment part 4 are connected by a first hook-and-loop fastener structure.

[0038] The connection is strong and has cushioning properties, and the adhesiveness of the hook-and-loop fastener allows it to be attached to the head support part 3 and the height adjustment part 4, while at the same time allowing it to adapt to slight misalignment between the parts with slight deformation.

[0039] The hook-and-loop fastener structure can be used repeatedly, and after bonding, relatively large displacement and misalignment do not occur between the head support part 3 and the height adjustment part 4.

[0040] Specifically, when there are more than two height-adjusting units 4, the adjacent height-adjusting units 4 are connected to each other by the second hook-and-loop fastener structure.

[0041] In this application, due to the generality of the hook-and-loop fastener structure, the fastener structure is not shown in the drawings. In actual operation, the number of embedded height adjustment parts 4 may be two, three, or even more. Specifically, the first hook-and-loop fastener structure and the second hook-and-loop fastener structure both include hook and loop surfaces and are general connection auxiliary materials.

[0042] Specifically, the inner cores of the back support part 2 and the head support part 3 are both made of low-resilience sponge, and the inner core of the height adjustment part 4 is made of high-resilience sponge.

[0043] The resilient sponge can fit the physiological curvature of the human body, automatically deforming according to the pressure on the head and back, adhering to the contours of the body, dispersing localized pressure and reducing the feeling of oppression.

[0044] The inner cores of the back support part 2 and the head support part 3 are both made of low-resilience sponge, and the inner core of the height adjustment part 4 is made of high-resilience sponge, and both are covered externally with pillowcases.

[0045] It should be noted that all directional indications in the embodiments of the present application, such as up, down, left, right, front, back, etc., are merely for interpreting a specific posture, the relative positional relationship between each member, the movement situation, etc. as shown in the drawings, and when this specific posture changes, the directional indications also change accordingly.
