Description

A supportive headboard and bed Technical Field

[0001] This invention belongs to the field of furniture technology and relates to a backrest and bed with good support. Background Technology

[0002] In existing bed designs, the headboard, as a crucial component for enhancing the user's rest experience, is typically filled with soft materials to provide necessary support and comfort. However, the types of fillings widely used in the market are relatively limited, mainly consisting of traditional soft materials such as sponge and foam. These fillings have certain limitations in performance: on the one hand, while overly soft fillings can increase the tactile comfort of the headboard to some extent, they fail to provide effective support for the back, potentially leading to fatigue or discomfort with prolonged use, and even affecting spinal health. On the other hand, while using firmer fillings to enhance support can improve the support effect to some extent, these fillings often lack sufficient elasticity and cannot adapt to the curves and postures of the body, thus reducing the headboard's fit and overall comfort. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by proposing a backrest and bed with good support, aiming to overcome the shortcomings of poor comfort in existing bed backrests.

[0004] This invention is implemented as follows:

[0005] A supportive backrest includes a backrest cover, which comprises an upper cover, a middle cover, and a lower cover. The inner cavities of the different covers are isolated from each other. The upper cover is filled with an upper filling material, the middle cover is filled with an intermediate filling material, and the lower cover is filled with a lower filling material. The upper and lower filling materials are softer than the middle filling material.

[0006] The upper layer corresponds to the neck and is filled with a softer material. The neck is one of the most naturally curved areas of the body; therefore, soft filling better conforms to the neck's curve, reducing pressure and providing comfortable support. The middle layer corresponds to the back and is filled with a more supportive material. The back is relatively flat and requires firmer support to maintain the spine's natural position. Therefore, the middle layer's filling has a moderate firmness, providing sufficient support while accommodating slight changes in the back's curve. The lower layer corresponds to the lumbar region and also uses a softer material. The lumbar region also has a pronounced natural curve; soft filling adapts to the lumbar curve, providing comfortable support and helping to relieve lumbar fatigue. Through the selection of fillings for the upper, middle, and lower layers, precise support is achieved for different parts of the body, improving the comfort and support of the backrest.

[0007] Preferably, the upper filling material is a mixture of down and plush toy. The lightweight texture of the down allows the upper layer to quickly adapt to the curve of the neck when it comes into contact with the user's neck, reducing the formation of pressure points and providing a better comfort experience. The addition of plush toy provides the upper layer with the necessary elasticity, allowing it to quickly return to its original shape when the user adjusts their posture, maintaining continuous support for the neck.

[0008] Preferably, the lower filling is a mixture of down and plush toy cotton. The lightweight texture of the down allows the lower layer to quickly adapt to the waistline when in contact with the user, reducing pressure points and providing a better comfort experience. The addition of plush toy cotton provides the necessary elasticity to the upper layer, allowing it to quickly return to its original shape when the user adjusts their posture, maintaining continuous support for the waist.

[0009] Preferably, the intermediate packing includes a second layer and a third layer, with the inner cavities of the second and third layers isolated from each other. The upper, second, third, and lower layers are of the same height and arranged sequentially from top to bottom. This prevents the intermediate filling material from accumulating at the bottom of the intermediate packing. This design not only ensures the neatness and aesthetics of the backrest, but more importantly, it allows each packing to play its unique supporting role, collectively providing the user with a comprehensive support experience.

[0010] Preferably, both the second and third layers of the backrest are filled with plush toy cotton. Plush toy cotton has good elasticity, breathability, and durability, and can quickly return to its original shape under pressure, thus providing continuous support for the user. At the same time, the breathability of plush toy cotton helps keep the back dry and comfortable, effectively preventing sweat buildup. The fact that both the second and third layers are filled with plush toy cotton creates a stable support layer in the middle layer. This design not only improves the support of the backrest but also ensures that different areas of the back receive even and moderate support, effectively relieving back fatigue and discomfort.

[0011] Preferably, the support bag includes a cover, the inside of which is sewn with dividers to separate the cover into multiple bags; the dividers divide the internal space of the cover into multiple independent cavities. Each cavity can be specially filled and designed according to the needs of different parts of the body, thereby providing users with more precise and comprehensive support. Alternatively, the different bags can be independent of each other, with adjacent bags fixedly connected by zippers. This facilitates the independent production of each bag.

[0012] Preferably, the backrest includes a headboard, which includes a back panel and a support platform. The cushion is located on the support platform and abuts against the front side of the back panel. The back panel of the headboard serves as the supporting structure for the backrest, and its front side fits tightly against the cushion, providing stable support for it. The support platform provides a stable placement platform for the cushion.

[0013] Preferably, the backrest has flexible protective layers at the top and both ends. The flexible protective layers cover the top and both ends of the backrest, effectively preventing the user from being injured by hard objects at the edges or corners when leaning against it. At the same time, it also prevents the backrest from being damaged by friction or impact during use.

[0014] Preferably, the backrest is covered with a cover. This not only enhances the overall aesthetics of the cushion but also makes it easier for users to clean and maintain it.

[0015] A bed, including the aforementioned headboard.

[0016] The present invention provides a backrest and bed with good support, which achieves precise support for different parts of the human body by selecting the filling materials of the upper, middle and lower layers, thereby improving the comfort and support of the backrest.

Embodiments of the present invention

[0028] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] Example 1

[0030] This embodiment provides a bed, which is a specific application of the innovative solution of the present invention on a bed. Specifically, as shown in Figures 1-7, the bed includes a backrest, and the backrest includes a backrest 100. The backrest 100 includes an upper backrest 110, a middle backrest, and a lower backrest 140. The inner cavities of the different backrests are isolated from each other. The upper backrest 110 is filled with an upper filling material 111, the middle backrest is filled with an intermediate filling material 121, and the lower backrest 140 is filled with a lower filling material 141. The upper filling material 111 and the lower filling material 141 are softer than the middle filling material 121.

[0031] The upper layer 110 corresponds to the neck and is filled with a softer material. The neck is one of the most physiologically curved areas of the human body; therefore, soft filling better conforms to the neck's curve, reducing neck pressure and providing comfortable support. The middle layer corresponds to the back and is filled with a more supportive material. The back is relatively flat and requires firmer support to maintain the spine's natural position. Therefore, the middle layer's filling has a moderate firmness, providing sufficient support while accommodating slight changes in the back's curve. The lower layer 140 corresponds to the lumbar region and also uses a softer material. The lumbar region also has a pronounced physiological curve; soft filling adapts to the lumbar curve, providing comfortable support and helping to relieve lumbar fatigue. Through the selection of fillings for the upper, middle, and lower layers 110, precise support for different parts of the body is achieved, improving the comfort and support of the backrest.

[0032] As shown in Figure 4, the upper filling 111 is a mixture of down and plush toy cotton. The lightweight texture of the down allows the upper filling 110 to quickly adapt to the curve of the neck when in contact with the user's neck, reducing the formation of pressure points and providing a better comfort experience. The addition of plush toy cotton provides the upper filling 110 with the necessary elasticity, allowing it to quickly return to its original shape when the user adjusts their posture, maintaining continuous support for the neck.

[0033] Furthermore, the lower filling 141 is a mixture of down and plush toy cotton. The lightweight texture of the down allows the lower layer 140 to quickly adapt to the waistline when in contact with the user's waist, reducing pressure points and providing a better comfort experience. The addition of plush toy cotton provides the upper layer 110 with the necessary elasticity, allowing it to quickly return to its original shape when the user adjusts their posture, maintaining continuous support for the waist.

[0034] In this embodiment, the upper filling material 111 and the lower filling material 141 are identical. In other optional embodiments, the upper filling material 111 and the lower filling material 141 can be different. In other optional embodiments, the upper filling material 111 and the lower filling material 141 can also be a mixture of natural latex and memory foam. Natural latex is known for its natural breathability and antibacterial properties, while memory foam can provide personalized support according to the curves of the human body. Although memory foam itself has a certain degree of firmness, it can achieve a softer effect than the middle layer by adjusting its density and thickness. The volume ratio of down and doll cotton in the upper filling material 111 and the lower filling material 141 can be selected as 8:2, with a higher proportion of down. This allows the upper and lower filling materials 110 to quickly adapt to the curves of the corresponding positions of the human body when in contact with the human body, reducing the formation of pressure points and providing users with a more fitting and natural support effect. Although the proportion of plush cotton is relatively small, its good elasticity is still preserved, allowing the upper layer 110 and lower layer 140 to maintain a certain degree of deformation capability when the user adjusts their posture, thereby continuously providing support for the waist. In other optional embodiments, the upper filling 111 and / or the lower filling 141 can also be entirely made of down.

[0035] As shown in Figures 2-5, the intermediate packing includes a second packing 120 and a third packing 130. The inner cavities of the second packing 120 and the third packing 130 are isolated from each other. The upper packing 110, the second packing 120, the third packing 130, and the lower packing 140 have the same height and are arranged sequentially from top to bottom. This avoids the accumulation of the intermediate filling 121 at the bottom of the intermediate packing. This design not only ensures the neatness and aesthetics of the backrest appearance, but more importantly, it allows each packing to play its unique supporting role, collectively providing the user with a comprehensive support experience. In other optional embodiments, the intermediate packing may also be a packing with only one inner cavity.

[0036] Furthermore, the intermediate filling 121 inside the second layer 120 and the third layer 130 is made of plush toy cotton. Plush toy cotton has good elasticity, breathability, and durability, and can quickly return to its original shape under pressure, thus providing continuous support for the user. At the same time, the breathability of the plush toy cotton also helps keep the back dry and comfortable, effectively preventing sweat buildup. The fact that both the second layer 120 and the third layer 130 are filled with plush toy cotton makes the intermediate layer a stable support layer as a whole. This design not only improves the support of the backrest but also ensures that different areas of the back receive even and moderate support, thereby effectively relieving back fatigue and discomfort.

[0037] In other alternative embodiments, the intermediate filling 121 can also be a mixture of down fibers and doll cotton, simply by adjusting the ratio of the two, for example, a volume ratio of down fibers to doll cotton of 2:8. In other alternative embodiments, the intermediate filling 121 can also be a mixture of memory foam and microfibers, which can maintain a certain level of support while avoiding excessive rigidity. In this case, the upper filling 111 and the lower filling 141 can be made of softer feathers or a mixture of down fibers and microfibers to ensure that the overall softness-hardness gradient meets the requirements.

[0038] As shown in Figures 5 and 6, the different bag bodies are independent of each other, and adjacent bag bodies are fixedly connected by zippers 160. This facilitates the independent production of each bag body, and each bag body can be specially filled and designed according to the needs of different parts of the human body, thereby providing users with more precise and comprehensive support.

[0039] As shown in Figures 1, 2, and 7, the backrest includes a headboard 200, which is a wooden frame structure. The headboard 200 includes a back panel 210 and a support platform 220. The cushion 100 is located on the support platform 220 and abuts against the front side of the back panel 210. The back panel 210 of the headboard 200 serves as the support structure for the backrest, and its front side fits tightly against the cushion 100, providing stable support for the cushion 100. The support platform 220 provides a stable placement platform for the cushion 100.

[0040] As shown in Figure 2, the backrest 100 has flexible protective layers 300 on its top and both ends. The flexible protective layers 300 are made of sponge material and their design covers the top and both ends of the backrest 100, effectively preventing users from being injured by hard objects on the edges or corners when leaning against the backrest 100. At the same time, it also prevents the backrest 100 from being damaged by friction or impact during use.

[0041] Furthermore, a cover 400 is fitted onto the backrest. This not only enhances the overall aesthetics of the backrest 100 but also facilitates cleaning and maintenance for the user.

[0042] Example 2

[0043] The main difference between this embodiment and Embodiment 1 lies in the structure of the backrest 100. As shown in Figures 8-10, specifically, the backrest 100 includes a cover 170, the inner side of which is sewn with a dividing fabric 150 to divide the cover 170 into multiple compartments; the dividing fabric 150 divides the internal space of the cover 170 into multiple independent cavities. Each cavity can be specially filled and designed according to the needs of different parts of the human body, thereby providing users with more precise and comprehensive support.

[0044] In actual use, as shown in Figure 8, the separator 150 may not completely cover the length of the wrapping sleeve 170. That is, the internal spaces of the wrapping sleeve 170 at both ends are connected. The separator 150 is only sewn to the corresponding inner edge of the wrapping sleeve 170 along its length. This simplifies the structure of the separator 150 being fixed inside the wrapping sleeve 170 and can still play a basic role in isolation.

[0045] The other structures in this embodiment are the same as in Embodiment 1.
