Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of textile, concretely relates to a kind of zip-like structure sponge pad and supporting pad. BACKGROUND

[0002] Children's spines undergo significant rapid growth and changes during growth, with infancy and adolescence being two key stages.

[0003] During infancy, around 3 months, as the head-lifting action develops, the cervical vertebrae begin to curve forward; by 6 months, when the baby can sit, the thoracic curvature appears, which is curved backward; and by 1 year when the baby learns to walk, the lumbar curvature forms. By 6 to 7 years, the three natural curves of the spine, the cervical curvature, the thoracic curvature and the lumbar curvature, are fixed by ligaments. During the adolescent growth period (9-12 years), the vertebral body size is close to that of an adult, and the spinal morphology is basically determined, and gradually forms the four natural physiological curves of the cervical curvature, the thoracic curvature, the lumbar curvature and the sacral curvature, which are usually fully formed at the age of 10.

[0004] In related technologies, sponge is commonly used as the material of children's mattress or pillow core. However, the existing sponge pad has the following problems: when the weight of the child changes, the mechanical transition between the layers of the mattress is discontinuous, which is easy to cause "pressure fault", and the shoulder, hip and other parts are subjected to sinking compression, while the waist is in a state of suspended support, which further aggravates the risk of imbalance of the spine stress. In addition, the sponge pad is easy to deform plastically, which leads to a decrease in supporting force and poor durability. SUMMARY

[0005] Therefore, the utility model provides a zip-like structure sponge pad and supporting pad to solve the above-mentioned technical problems of discontinuous mechanical transition between the layers of the mattress, easy to cause "pressure fault", which leads to sinking compression of the shoulder, hip and other parts, while the waist is in a state of suspended support, which further aggravates the risk of imbalance of the spine stress.

[0006] To achieve the above-mentioned scheme, the technical scheme of the utility model is as follows:

[0007] In a first aspect, the utility model provides a zip-like structure sponge pad, which comprises an upper layer and a lower layer. The bottom of the upper layer is provided with a plurality of upper teeth, and the top of the lower layer is provided with a plurality of lower teeth. The upper teeth and the lower teeth are interlocked. The density of the lower layer is greater than or equal to 25 kg / m 3 , and the difference between the density of the lower layer and the density of the upper layer is 2-5 kg / m 3 .

[0008] The principle of the sponge pad with the zipper-like structure is that: the sponge pad with the zipper-like structure is provided with an upper layer and a lower layer, a plurality of upper teeth are additionally arranged at the bottom of the upper layer, a plurality of lower teeth are additionally arranged at the top of the lower layer, the upper teeth and the lower teeth are mutually engaged, and the density of the lower layer is greater than or equal to 25 kg / m 3 , and the difference between the density of the lower layer and the density of the upper layer is 2-5 kg / m 3 , so that a differentiated density structure of the upper and lower layers can be formed, and a progressive support system is formed, thereby avoiding the problems of the shoulder, hip and other parts being subjected to sinking compression and the waist being suspended and supported in the prior art, and the risk of imbalance of the spine stress is aggravated.

[0009] In addition, the inventor has found that the existing children's mattress has the following defects: it cannot adapt to the rapid change of the spinal curvature and body weight distribution of children aged 3-12 years old, and it is difficult to adapt to the body size change of children during rapid growth, for example, in the infant period (3-6 years old), the support of the waist and hip area needs to be strengthened to prevent kyphosis; in the school age period (7-10 years old), the rapidly increasing body weight load needs to be evenly distributed; in the prepuberty period (10-12 years old), preventive support for scoliosis is also needed, and the commercially available mattress lacks an adjustable mechanism, and can only be replaced to achieve stage adaptation, resulting in waste of resources; the comfort needs to be improved, and the mattress not only needs to have good support performance, but also should provide scientific and reasonable comfort performance, the small arteriole capillary pressure bearing capacity of children aged 0-9 years old needs to be soft, and children aged 10 years old and above need to support the spine and sleep on a hard end, and the use of a too soft mattress may increase the risk of scoliosis, and long-term use of a hard mattress may affect sleep comfort.

[0010] Optionally, the upper teeth are distributed along the longitudinal direction, the upper teeth comprise a base and a crown in the form of an arc-shaped protrusion, along the longitudinal direction, the sponge pad with the zipper-like structure is sequentially divided into a first zone, a second zone, a third zone, a fourth zone, a fifth zone and a sixth zone, and the upper teeth and the lower teeth satisfy the following relationship formulas (a) and (b):

[0012] (b) 2.2 ≤ λ5 ≤ 2.4, λ5 > λ2, and λ2 is greater than λ1, λ3, λ4 and λ6;

[0014] Specifically, the upper teeth and the lower teeth are arranged to meet the relationship (a) and (b), so that a progressive support system is formed by differentiating the dense and sparse structures in the head and tail areas, to adapt to the support needs of different parts of the child's body, reduce local pressure points such as shoulders and hips, help to relieve muscle tension and pain, promote deep sleep, and improve sleep quality; and while ensuring good elasticity, the stability of the structure is ensured; the first area, the second area, and the third area provide comfortable pressure relief effect for younger children (0-9 years old, not including 9 years old), and the third area, the fourth area, the fifth area, and the sixth area are used by rotating 180° to provide favorable support for teenagers (over 9 years old); in addition, the body weight can be evenly distributed when lying down, reducing local pressure points such as shoulders and hips, and the sponge quickly rebounds when turning over, reducing sleep disturbance, prolonging deep sleep time, and improving sleep quality.
