Description

TECHNICAL FIELD

[0001] The utility model belongs to furniture technical field relates to a backrest and bed with good supporting property. BACKGROUND

[0002] In the existing bed design, the bed backrest as the important component of promoting user rest experience, its inside is usually filled with soft material to provide necessary support and comfort. However, the filling widely used in the current market is single, mainly traditional soft material such as sponge, foam plastic. This kind of filling has certain limitation in performance: on the one hand, when the filling is too soft, although it can increase the touch comfort of backrest to a certain extent, it is difficult to form effective supporting force to the back of human body, and long-term use can cause user to feel fatigue or discomfort, and even affect the health of spine. On the other hand, if the filling with relatively hard texture is selected to enhance the supporting property, although it can improve the supporting effect to a certain extent, this kind of filling often lacks sufficient elasticity, and cannot adapt to the curve and posture of human body, thereby reducing the fitting degree and overall comfort of backrest. SUMMARY

[0003] The utility model provides a backrest and bed with good supporting property aiming at the problems existing in the prior art, to overcome the defects of poor comfort of the existing bed backrest.

[0004] The utility model is realized as follows:

[0005] A backrest with good supporting property, including back bag, the back bag includes upper layer package body, intermediate package body and lower layer package body, the inner cavity between different package bodies is isolated, the upper layer package body is filled with upper layer filling, the intermediate package body is filled with intermediate filling, the lower layer package body is filled with lower layer filling, the upper layer filling and lower layer filling are softer than the intermediate filling.

[0006] The upper layer package body corresponds to the neck of human body, and is filled with relatively soft filling. The neck is one of the most obvious parts of human physiological curve, therefore, the soft filling can better fit the curve of neck, reduce the pressure of neck, and provide comfortable support. The intermediate package body corresponds to the back of human body, and is filled with filling with better supporting property. The back is relatively flat, and needs more solid support to maintain the natural state of spine. Therefore, the hardness of the filling of intermediate package body is moderate, which can provide sufficient supporting force and adapt to the slight curve change of back. The lower layer package body corresponds to the waist of human body, and also uses relatively soft filling. The waist is also a part with relatively obvious physiological curve, and the soft filling can adapt to the curve of waist, provide comfortable support for waist, and help to relieve the fatigue of waist. Through the selection of the filling of upper layer package body, intermediate package body and lower layer package body, the precise support to different parts of human body is realized, and the comfort and supporting property of backrest are improved.

[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, the intermediate filling material in both the second and third layers of the package is plush cotton. Plush 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 cotton also helps keep the back dry and comfortable, effectively preventing sweat buildup.

[0011] Both the second and third layers of the backrest are filled with plush toy cotton, creating a stable support layer within the middle layer. This design not only enhances the backrest's support but also ensures even and appropriate support for different areas of the back, effectively relieving back fatigue and discomfort.

[0012] Preferably, the support bag includes a cover, the inside of which is sewn with a dividing fabric to divide the cover into multiple bags; the dividing fabric divides 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 human body, thereby providing users with more precise and comprehensive support.

[0013] Alternatively, different packages can be produced independently, with adjacent packages secured together by zippers. This allows for independent production of each package.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] A bed, including the aforementioned headboard.

[0018] 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.

Detailed Implementation

[0030] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of this utility model easier to understand and master. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0031] Example 1

[0032] This embodiment provides a bed, which is a specific application of the innovative solution of this utility model in the field of beds. Specifically, as follows... Figures 1-7 As shown, the bed includes a backrest, which 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.

[0033] 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.

[0034] like Figure 4As shown, 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 it comes into contact with the user's neck, reducing the formation of pressure points and providing a better comfort experience for the user. 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.

[0035] 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.

[0036] 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 may be different. In other optional embodiments, the upper filling material 111 and the lower filling material 141 may 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.

[0037] The volume ratio of down and plush toner in both the upper filling 111 and the lower filling 141 can be selected as 8:2, with a higher proportion of down. This allows the upper and lower fillings to quickly adapt to the curves of the body when in contact with it, reducing pressure points and providing a more fitting and natural support. Although the proportion of plush toner is relatively small, its good elasticity is still preserved, allowing the upper and lower fillings to maintain a certain degree of deformation when the user adjusts their posture, thus continuously providing support for the lower back. In other optional embodiments, the upper filling 111 and / or the lower filling 141 can also be entirely composed of down.

[0038] like Figures 2-5As shown, 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 are of the same height and 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.

[0039] Furthermore, the intermediate filling 121 inside the second layer 120 and the third layer 130 is made of plush cotton. Plush 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 cotton also helps keep the back dry and comfortable, effectively preventing sweat buildup.

[0040] Both the second layer (120) and the third layer (130) are filled with plush toy cotton, creating a stable support layer within the middle layer. This design not only enhances the backrest's support but also ensures even and appropriate support for different areas of the back, effectively relieving back fatigue and discomfort.

[0041] 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.

[0042] like Figure 5 , 6 As shown, the different bag units are independent of each other, and adjacent bag units are fixedly connected by zippers 160. This facilitates the independent production of each bag unit, and each bag unit 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.

[0043] like Figure 1 , 2As shown in Figure 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 is in close contact with the cushion 100, providing stable support for the cushion 100. The support platform 220 provides a stable placement platform for the cushion 100.

[0044] like Figure 2 As shown, 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.

[0045] 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.

[0046] Example 2

[0047] The main difference between this embodiment and Embodiment 1 lies in the structure of the retainer 100. For example... Figures 8-10 As shown, specifically, the support bag 100 includes a cover 170, the inner side of which is sewn with a dividing fabric 150 to divide the cover 170 into multiple bags; 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.

[0048] In actual use, such as Figure 8 As shown, 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.

[0049] The other structures in this embodiment are the same as in Embodiment 1.
