[0039] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.
[0040] A new type of bed back filling structure, referring to Figure 1 and Figure 2 , including a support frame 1. In the present embodiment, the support frame 1 adopts a wooden frame structure to ensure the strength support of the bed backrest. In other embodiments, the support frame 1 may also adopt a steel structure frame, or a frame made of other materials, as long as it can provide high-strength support.
[0041] A buffer layer 2 is provided on the surface of the support frame 1. By providing the buffer layer 2, the user is prevented from directly contacting the support frame 1 when using the bed backrest, thereby reducing the stiffness during use. In the present embodiment, the height of the buffer layer 2 is 3 cm, and other heights may be used in other embodiments, which may be selected according to actual conditions. The buffer layer 2 may be fixed to the support frame 1 by glue, and may be fixed to the support frame 1 by Velcro or other means. In the present embodiment, the buffer layer 2 is made of sponge, and the sponge is a high-resilience sponge that can play a high buffering role, and the sponge is wrapped in cloth to reduce the possibility of the sponge being damaged and scattered during use. In other embodiments, the buffer layer 2 may also be made of latex pads or other materials, as long as they can play a buffering role.
[0042] In order to further increase the cushioning effect, an elastic band 3 is provided on the side of the buffer layer 2 away from the support frame 1. The two ends of the elastic band 3 correspond to the two ends of the support frame 1 one by one and are fixedly connected to the support frame 1, so that the elastic band 3 is stretched straight on the surface of the buffer layer 2. Therefore, when the user uses the bed backrest, the elastic band 3 and the buffer layer 2 can cushion the user at the same time, and compared with the buffer layer 2, the elastic band 3 has a certain supporting force, can provide a certain support to the user, and increase the user's experience.
[0043] In this embodiment, there are several elastic bands 3, and the width of each elastic band 3 is 6 cm, and the several elastic bands 3 are crisscrossed to form a mesh structure; in other embodiments, only one elastic band 3 can be provided, and the width of the elastic band 3 is the same as the width of the buffer layer 2.
[0044] In order to release the force of the bed back uniformly when the user uses the bed back, a cotton isolation layer 4 is provided on the side of the elastic band 3 away from the buffer layer 2. The cotton isolation layer 4 is fixedly connected to the elastic band 3 to form a whole, so that several elastic bands 3 can be evenly compressed, ensuring that the force of the bed back is evenly released. In this embodiment, the cotton isolation layer 4 is glued to the elastic band 3 by glue. In other embodiments, the cotton isolation layer 4 can be fixedly connected to the elastic band 3 by Velcro or other methods, as long as the cotton isolation layer 4 and the elastic band 3 can be fixed to each other to form a whole.
[0045] The side of the cotton sheet isolation layer 4 away from the elastic band 3 is provided with an elastic layer 5, which provides secondary buffering. However, if only one buffer layer 2 is provided, it is easy to collapse after long-term use. By providing the elastic layer 5, double buffering is achieved to reduce the occurrence of collapse. In this embodiment, the elastic layer 5 uses springs 51, and there are a plurality of springs 51, which are evenly distributed on the cotton sheet isolation layer 4.
[0046] In order to reduce the interference between adjacent springs 51, each spring 51 adopts an independent pocket spring 51, and adjacent springs 51 are connected by the mounting belt of the pocket spring 51, and two adjacent mounting belts are fixedly connected to each other, thereby ensuring that several springs 51 are connected to each other, and during the user's use, the interference between the springs 51 is small.
[0047] Reference Figure 3 and Figure 4 The elastic layer 5 can also be made of bio-based materials. The elastic layer 5 includes a plurality of first biological base layers 52 and a plurality of second biological base layers 53. The first biological base layers 52 are repeatedly bent to form a wavy shape, and the second biological base layers 53 are planar. One second biological base layer 53 is arranged between adjacent first biological base layers 52. The plurality of first biological base layers 52 and the plurality of second biological base layers 53 together form the elastic layer 5.
[0048] Reference Figure 1 and Figure 2 The elastic layer 5 is provided with a pressure relief layer 6 on one side away from the cotton isolation layer 4. The pressure relief layer 6 is provided to provide the user with a comfortable wrapping experience, so that the user can feel wrapped by the pressure relief layer 6 when leaning on the bed backrest, thereby improving the use experience. In this embodiment, the pressure relief layer 6 is a feather pad, and in other embodiments, a cotton pad or other material pressure relief layer 6 can also be used.
[0049] The feather pad includes a cloth bag and feathers filled in the cloth bag. In order to increase the comfort of the feather pad, the cloth bag is also filled with down silk, and the ratio of feathers to down silk is 3:7, so that the feather pad has the softness of feathers and the resilience of down silk, which increases the user experience. In order to reduce the accumulation of down silk and feathers in the down pad, a number of small bags are sewn on the cloth bag, and the small bags are evenly distributed on the inner wall of the cloth bag. Each small bag is filled with feathers and down silk, which reduces the accumulation of feathers and down silk. In other embodiments, some small bags may be filled with feathers alone, and another part of the small bags may be filled with down silk alone. It is also possible that all small bags are filled with down silk, and the feathers are filled in the cloth bag.
[0050] The end of the pressure relief layer 6 away from the elastic layer 5 is provided with a covering layer 7, and the covering layer 7 covers the pressure relief layer 6, the elastic layer 5, the cotton isolation layer 4, the elastic band 3 and the buffer layer 2. The covering layer 7 can be made of plush cloth, leather and other materials, which can be adapted to various user usage scenarios.
[0051] In order to reduce the occurrence of wrinkles on the covering layer 7, an elastic cotton support layer 8 is provided between the covering layer 7 and the pressure-relieving layer 6. The elastic cotton support layer 8 provides a full feeling to the covering layer 7 and reduces the occurrence of wrinkles on the fabric.
[0052] The implementation principle of the embodiment of the present application is: a buffer layer 2 is set to provide basic buffering, an elastic layer 5 is set to provide secondary buffering, which increases the use experience and can improve the sense of wrapping, and a pressure relief layer is set to further provide a sense of wrapping and increase the user experience.
[0053] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
