Description

Technical Field

[0001] The invention relates to the technical field of sleeping support, and in particular to a mattress for different ages with bidirectional support. Background Art

[0002] In the field of mattress design, in view of the needs of adolescents, the support structure of the mattress is crucial to the spinal health of adolescents. However, the existing mattress designs on the market have the following shortcomings:

[0003] ① Single support structure: Most mattresses on the market currently use a single support structure. This design cannot adapt to the changes in height and body shape of teenagers during their growth, especially the growth needs of the spine. It cannot provide variable sleep support during the growth of teenagers, which is not conducive to the sleep health of teenagers.

[0004] ② Unscientific partition size design: Partially partitioned mattresses can solve the problem of a single supporting structure, but the partition design of traditional mattresses simply divides the bed net into several uniform areas. This design method is not ergonomic and does not partition according to actual human body size data.

[0005] Specifically, when designing a zoned mattress, the specific length of each support zone is a key design parameter.

[0006] Some national standard documents (for example, "Human Body Dimensions of Chinese Minors" and "Human Body Dimensions of Chinese Adults") provide some static human body dimensions for reference. In theory, the width dimensions of each support partition can be determined by referring to the above national standard documents, and then the design of the partitioned mattress can be completed.

[0007] Taking "Human Dimensions of Chinese Minors" as an example, see Figure 1 , the standard document gives the static human dimensions of minors including: height, shoulder height, perineum height, anterior superior iliac spine height and upper arm length;

[0008] Among them, the above-mentioned static human body dimensions such as height, shoulder height, perineum height, height of the anterior superior iliac spine, and upper arm length do not require complex technical means such as X-ray photography, and can be directly obtained by simple measurements on the human body surface. They are "directly measurable body surface dimensions."

[0009] The waist usually refers to the location of the lumbar spine, that is, from the first lumbar vertebra L1 to the fifth lumbar vertebra L5. The first lumbar vertebra L1 and the fifth lumbar vertebra L5 are structural features inside the human body and cannot be directly obtained by simple measurement on the human body surface. Therefore, the waist length of the human body cannot be directly obtained through the existing national standard documents.

[0010] Since the human waist length cannot be directly obtained, the existing method for determining the partition size of the partitioned mattress is often to first determine the length of the head partition, back partition, leg partition, etc. based on the static human body size, and then use the remaining space as the waist partition, that is, the width size of the waist partition is determined last, and its matching degree with the actual waist length size is low. Therefore, the partitioned mattress determined in this way also has poor comfort in waist support.

[0011] In fact, when providing sleeping support to various parts of the human body, lumbar support is the most critical. Therefore, the final design method for determining the length of the lumbar area is extremely unreasonable.

[0012] Therefore, the present invention is committed to developing a bidirectional support mattress for different ages, which is used to solve the problems of the single support structure and unscientific partition size design of existing mattresses, thereby improving the comfort of sleep support for teenagers and promoting their sleep health.

[0013] The above information is presented as background information only to assist with understanding the present disclosure and no determination or admission is made as to whether any of the above may be used as prior art with respect to the present disclosure. Summary of the invention

[0014] The present invention provides a bidirectional support mattress for different ages, which can effectively solve the problems of single support structure and unscientific partition size design of existing mattresses, thereby improving the comfort of sleep support for teenagers and promoting their sleep health.

[0015] To achieve the above object, the present invention provides a mattress for different ages with bidirectional support, comprising: a waist area for younger age groups, a waist area for older age groups, and a hip and leg common area between the waist area for younger age groups and the waist area for older age groups, wherein the width of the waist area for younger age groups and / or the waist area for older age groups is obtained by a method for determining waist length of a human body;

[0016] The method for determining waist length of a human body comprises:

[0017] Obtain several static human dimensions of corresponding age groups;

[0018] According to the static human body dimensions, a distance dimension A from the elbow joint to the end position of the fifth lumbar vertebra L5 is calculated;

[0019] Determine the number of lumbar vertebrae n included in the end position from the elbow joint to the fifth lumbar vertebra L5;

[0020] The waist length dimensions of the five lumbar vertebrae of the corresponding age group are determined according to the distance dimension A and the number of lumbar vertebrae n.

[0021] Optionally, the number of lumbar vertebrae n satisfies the following relationship: 3≤n≤4; waist length dimension = (5 / 3+5 / 4)·A / 2.

[0022] Optionally, the width dimension of the lower-age waist region is smaller than the width dimension of the higher-age waist region.

[0023] Optionally, a side of the low-age waist area away from the hip-leg common area is provided with a low-age shoulder and back area and a low-age head and neck area in sequence;

[0024] The side of the senior waist area away from the hip and leg common area is provided with a senior shoulder and back area and a senior head and neck area in sequence;

[0025] Optionally, the width dimension of the younger shoulder and back partition is smaller than the width dimension of the older shoulder and back partition.

[0026] Optional,

[0027] The static human dimensions include shoulder height, upper arm length, and anterior superior iliac spine height, wherein the distance dimension A=shoulder height-upper arm length-anterior superior iliac spine height.

[0028] Optional,

[0029] The width of the head and neck partition = height - shoulder height;

[0030] The width of the shoulder and back area = shoulder height - height of the anterior superior iliac spine - waist length;

[0031] The width of the waist area = the waist length;

[0032] The width of the buttocks and legs area = the height of the anterior superior iliac spine.

[0033] Optionally, low-hardness springs are correspondingly arranged in the four areas: the low-age waist area, the low-age head and neck area, the high-age waist area, and the high-age head and neck area;

[0034] The three areas of the shoulder and back area for young children, the area shared by the hip and legs, and the shoulder and back area for old people are all provided with high-hardness springs;

[0035] Among them, the support hardness of the low-hardness spring is smaller than the support hardness of the high-hardness spring.

[0036] Optionally, at least one of the waist diameter, wire diameter, and elastic modulus of the springs in different partitions is different.

[0037] Optionally, the width dimensions of the younger head and neck partition, younger shoulder and back partition, younger waist partition, hip and leg common partition, older waist partition, older shoulder and back partition, and older head and neck partition are 330mm, 180mm, 130mm, 440mm, 170mm, 240mm, and 330mm respectively.

[0038] Compared with the prior art, the present invention has the following beneficial effects, providing a bidirectional support mattress for different ages:

[0039] ① By providing two waist zones for young and old people, the mattress can adapt to the physical changes of children and adolescents at different growth stages. Only by changing the sleeping position, it can provide sleeping support suitable for the age group. It is ergonomic and solves the problem of the single support structure of traditional mattresses.

[0040] ② By using static human body size data, first determine the distance dimension A corresponding to the length of n lumbar vertebrae, and then determine the waist length based on A and n, thereby providing a reference for mattress zoning design, making the mattress support more ergonomic, improving the comfort of adolescent sleep support and promoting adolescent sleep health.

[0041] Therefore, the age-specific bidirectional support mattress provided by the present invention can effectively solve the problems of the single support structure and unscientific partition size design of existing mattresses, thereby improving the comfort of sleep support for teenagers and promoting their sleep health.

[0065] Example 1

[0066] Please refer to the attached Figure 3 , is a flow chart of a method for determining waist length of a human body provided by an embodiment of the present invention. The method is applicable to the scenario of obtaining waist length dimension (from the boundary line of the thoracolumbar vertebrae to the end position of the fifth lumbar vertebra L5). It can determine the waist length dimension of a human body according to the static human body dimension, so as to provide a reference for the design of mattress partitions, thereby improving the comfort of sleep support. The method specifically includes the following steps:

[0067] S101: Obtaining several static human body dimensions;

[0068] In this embodiment, several static human dimensions can be obtained from "Human Dimensions of Chinese Minors" and / or "Human Dimensions of Chinese Adults", wherein the static human dimensions include at least one of height, shoulder height, perineum height, anterior superior iliac spine height, upper arm length, thigh length, and tibia height.

[0069] Specifically,

[0070] The static body dimensions of minors that can be directly obtained from the Human Dimensions of Chinese Minors include: height, shoulder height, perineum height, anterior superior iliac spine height and upper arm length;

[0071] The static body dimensions of adults that can be directly obtained from "Chinese Adult Body Dimensions" include: height, shoulder height, upper arm length, perineum height, thigh length, and shin point height.

[0072] It should be noted that when obtaining static human body dimensions from "Human Body Dimensions of Chinese Minors" and "Human Body Dimensions of Chinese Adults", you can only take the value of the 50th percentile (P50). This is because the 50th percentile (P50) size is usually used as a representative of "average" or "medium" size. Zoning design based on P50 data is conducive to making the designed partitions suitable for "average height" individuals in most of the population.

[0073] S102: Calculate the distance A from the elbow joint to the end position of the fifth lumbar vertebra L5 according to the static human body dimensions;

[0074] For minors, the "Human Dimensions of Chinese Minors" is used as the basis: distance dimension A = shoulder height - upper arm length - height of the anterior superior iliac spine;

[0075] For adults, the "Chinese Adult Body Dimensions" is used as the basis: distance dimension A = shoulder height - upper arm length - (thigh length + tibia point height).

[0076] S103: Determine the number n of lumbar vertebrae included in the end position from the elbow joint to the fifth lumbar vertebra L5;

[0077] The human spine has 12 thoracic vertebrae and 5 lumbar vertebrae. In anatomy, the end position of the twelfth thoracic vertebra T12 is defined as the dividing point between the thoracic and lumbar vertebrae (thoracolumbar dividing line). Therefore, the total length of the twelve thoracic vertebrae is defined as the shoulder and back length, and the length of the five lumbar vertebrae is defined as the waist length.

[0078] When conducting human body measurements in "Human Dimensions of Chinese Minors" and "Human Dimensions of Chinese Adults", the reference standard document is "GB / T 5703-2010 Basic Items of Human Body Measurements for Technical Design". "GB / T 5703-2010 Basic Items of Human Body Measurements for Technical Design" states that the measurement method for upper arm length is the vertical distance from the acromion point to the lower edge of the elbow point of the horizontally bent forearm (hereinafter referred to as "elbow joint").

[0079] See also Figure 4 For the general human structure, the starting positions of the two static human dimensions, the height of the anterior superior iliac spine and the length of the thigh, are basically matched with the position of the fifth lumbar vertebra L5; however, there is a significant difference between the end position of the upper arm length (i.e., the elbow joint) and the starting position of the first lumbar vertebra L1 (i.e., the thoracolumbar dividing line). Specifically, the elbow joint is obviously lower than the thoracolumbar dividing line. Therefore, the distance dimension A from the elbow joint to the end position of the fifth lumbar vertebra L5 is not the true length dimension of the five lumbar vertebrae, which is slightly larger than A.

[0080] from Figure 4 It can be seen that the position of the elbow joint corresponds to the position of the second lumbar vertebra L2, that is, the elbow joint is between the starting position of the second lumbar vertebra L2 and the ending position of the second lumbar vertebra L2; then, the number of lumbar vertebrae n included in the ending position from the elbow joint to the fifth lumbar vertebra L5 is 3 (third lumbar vertebra L3~fifth lumbar vertebra L5)~4 (second lumbar vertebra L2~fifth lumbar vertebra L5).

[0081] Therefore, the distance A from the elbow joint to the end position of the fifth lumbar vertebra L5 is the length of 3 to 4 lumbar vertebrae.

[0082] S104: Determine the waist lengths of five lumbar vertebrae according to the distance dimension A and the number of lumbar vertebrae n.

[0083] Generally speaking, the lengths of the lumbar vertebrae are not much different:

[0084] If the distance A from the elbow joint to the end position of the fifth lumbar vertebra L5 is 3 segments, the length of a single lumbar vertebra is A / 3. At this time, the actual length of the five lumbar vertebrae is 5A / 3.

[0085] If the distance A from the elbow joint to the end position of the fifth lumbar vertebra L5 is 4 segments, the length of a single lumbar vertebra is A / 4. At this time, the actual length of the five lumbar vertebrae is 5A / 4.

[0086] If the distance A from the elbow joint to the end position of the fifth lumbar vertebra L5 for half of the people is 3 sections, and the distance A from the elbow joint to the end position of the fifth lumbar vertebra L5 for the other half of the people is 4 sections, then the average value of the two can be taken as a reference for subsequent design, that is:

[0087] Waist length size = (5 / 3+5 / 4)·A / 2=35A / 24.

[0088] In summary, the method for determining the waist length of a human body provided in this embodiment first determines the distance dimension A corresponding to the length dimension of n lumbar vertebrae through the existing static human body dimensions, and then determines the waist length dimensions of the five lumbar vertebrae according to the distance dimension A and the number of lumbar vertebrae n. In this way, the waist length dimension that is not explicitly stated in the existing technology can be calculated, so as to provide a reference for the mattress zoning design, thereby improving the comfort of sleep support.

[0089] Example 2

[0090] This embodiment provides a mattress zoning method, which is suitable for application scenarios where the size of each support partition is limited according to the waist length size provided in Example 1. It can improve the scientificity and rationality of the partition size design and further improve the comfort of sleep support.

[0091] See also Figure 5 The mattress partitioning method provided in this embodiment includes the following steps:

[0092] S201: Obtain waist length according to any method for determining waist length of a human body described in Example 1;

[0093] The specific method for obtaining the waist length has been introduced in Example 1. Based on Example 1, the features not explained in this embodiment are explained in Example 1 and will not be repeated here.

[0094] S202: Determine the width of each supporting partition according to the waist length;

[0095] In this embodiment, the two files "Human Body Dimensions of Chinese Minors" and "Human Body Dimensions of Chinese Adults" provide different static human body dimensions. Therefore, when designing the mattress partitions:

[0096] ①See Figure 6 , the mattress designed according to the static human body dimensions provided in the "Human Body Dimensions of Chinese Minors" is a partitioned mattress suitable for minors;

[0097] ②See Figure 7 The mattress designed according to the static human body dimensions provided in the "Chinese Adult Human Body Dimensions" is a partitioned mattress suitable for adults;

[0098] Furthermore, currently, most of the zoned mattresses available on the market have a three-zone or five-zone structure.

[0099] Specifically, when it is a three-zone structure, each of the support zones includes a head, shoulder and back zone (zone one), a waist and hip zone (zone two), and a leg zone (zone three);

[0100] When it is a five-zone structure, each of the support zones includes a head and neck zone (zone one), a shoulder and back zone (zone two), a waist zone (zone three), a hip zone (zone four) and a leg zone (zone five).

[0101] Therefore, according to the suitable population and the number of partitions as the division criteria, the mattress partitioning method in this embodiment can be further refined as follows:

[0102] A. Three-zone mattress partitioning method suitable for minors;

[0103] B. Five-zone mattress partitioning method suitable for minors;

[0104] C. Three-zone mattress partitioning method suitable for adults;

[0105] D. Five-zone mattress zoning method suitable for adults.

[0106] A: Three-zone mattress partitioning method suitable for minors

[0107] At this time, in step S202:

[0108] The width of the head-shoulder-back area = height - height of the anterior superior iliac spine - waist length;

[0109] The width of the waist and hip area = waist length + (height of the anterior superior iliac spine - height of the perineum) + transition size;

[0110] The width of the leg area = perineum height - transition size;

[0111] Among them, the transition size is 5cm~10cm.

[0112] B: Five-zone mattress partitioning method suitable for minors

[0113] At this time, in step S202:

[0114] The width of the head and neck partition = height - shoulder height;

[0115] The width of the shoulder and back area = shoulder height - height of the anterior superior iliac spine - waist length;

[0116] The width of the waist area = the waist length;

[0117] The width of the buttocks partition = the height of the anterior superior iliac spine - the height of the perineum + the transition size;

[0118] The width of the leg area = perineum height - transition size;

[0119] Among them, the transition size is 5cm~10cm.

[0120] C: Three-zone mattress partition method suitable for adults

[0121] At this time, in step S202:

[0122] Width of head-shoulder-back zone = height - waist length - (thigh length + shin point height);

[0123] The width of the waist and hip area = waist length + (thigh length + tibia height - perineum height) + transition size;

[0124] The width of the leg area = perineum height - transition size;

[0125] Among them, the transition size is 5cm~10cm.

[0126] D: Five-zone mattress partition method suitable for adults

[0127] At this time, in step S202:

[0128] The width of the head and neck partition = height - shoulder height;

[0129] The width of the shoulder and back area = shoulder height - (thigh length + shin point height) - waist length;

[0130] The width of the waist area = the waist length;

[0131] The width of the buttocks zone = (thigh length + tibia point height) - perineum height + transition size;

[0132] The width of the leg area = perineum height - transition size;

[0133] Among them, the transition size is 5cm~10cm.

[0134] It should be noted that the "Human Dimensions of Chinese Minors" and "Human Dimensions of Chinese Adults" refer to the national standard document "GB / T 5703-2010 Basic Items of Human Measurement for Technical Design" when conducting human body measurements;

[0135] GB / T 5703-2010 Basic Items of Anthropometric Measurements for Technical Design states that the measurement method of perineum height is the vertical distance from the ground to the bottom of the pubic symphysis. Since the lower edge of the buttocks (the natural wrinkle at the junction of the lower edge of the gluteus maximus and the back of the thigh) and the bottom of the pubic symphysis are not on the same horizontal line, the lower edge of the buttocks is lower in the vertical direction relative to the bottom of the pubic symphysis, that is, the height of the lower edge of the buttocks is smaller than the data of perineum height. Therefore, the data of perineum height is not equal to the leg length. Taking into account the transition problem of the buttocks position, the leg length will be reduced by 5 cm to 10 cm from the data of perineum height (referred to as "transition size" in this application). Correspondingly, the buttocks length will be increased by 5 cm to 10 cm based on the height of the anterior superior iliac spine point - perineum height (adults: thigh length + tibial point height - perineum height). That is, the calculation formula for the leg is perineum height - transition size.

[0136] S203: performing size compensation on the support area and / or the leg area corresponding to the head according to the width of the pillow, and determining a final width size of the support area and / or the leg area corresponding to the head;

[0137] In the above mattress partitioning methods A to D, generally, the sum of the width dimensions of each support partition (generally less than 180cm) will be smaller than the actual length of the bed net. Take a 180×200cm mattress as an example, the width of the surrounding strip is 1cm. If there is an edge reinforcement system around (width 8cm), the bed net size is 162×182cm in width×length; if there is no edge reinforcement system around (width 8cm), the bed net size is 177×197cm in width×length; that is, whether it is 182cm with an edge reinforcement system or 197cm without an edge reinforcement system, it will be greater than 180cm. Excess size = total length of bed net - sum of the width dimensions of each support partition.

[0138] The excess size can be handled as follows:

[0139] When the width of the support area where the head is located (i.e. the head-shoulder-back partition or the head-neck partition) is smaller than the width of the pillow (the width of the pillow is usually 40×60cm or 48×74cm), at least part of the excess size will be compensated to the support area where the head is located to ensure that the pillow can be placed normally. In this way, the waist and hips or the shoulder and back can correctly correspond to the position of the shoulder or waist. After ensuring that the support area where the head is located can normally accommodate the pillow, the remaining excess size will be compensated to the leg area.

[0140] It should be noted that for mattresses with edge reinforcement systems, when considering whether a pillow can be placed in the support area where the head is located, the width of the edge reinforcement system should also be taken into consideration, that is:

[0141] If (the width of the support area where the head is located + the width of the edge reinforcement system) < the width of the pillow, it can be considered that the size of the support area where the head is located is not enough to accommodate the pillow, and the excess size should be compensated to the support area where the head is located first;

[0142] On the contrary, if (the width of the support area where the head is located + the width of the edge reinforcement system) > the width of the pillow, it can be considered that the size of the support area where the head is located is sufficient to accommodate the pillow, and the excess size can be compensated to the leg area.

[0143] S204: Calculate and obtain the number of rows of independent tube springs corresponding to each supporting partition according to the waist diameter of the independent tube spring and the width size of each supporting partition after compensation.

[0144] After obtaining the final width dimension of each supporting partition, the number of rows of independent tube springs corresponding to each supporting partition can be obtained by dividing the width dimension of each supporting partition by the waist diameter of the independent tube spring.

[0145] Among them, for a three-zone mattress, the hardness of the waist and buttocks is higher than that of the head, shoulders, back and legs; for a five-zone mattress, the hardness of the head, neck, waist and legs is higher than that of the shoulders, back and buttocks.

[0146] The following is an example with specific parameters:

[0147] The target group of a children's mattress is 7-12 years old. We want to design a five-zone independent spring mattress suitable for children of this age group. First, based on the human body data in GB / T 26158-2010 "Human Body Dimensions of Chinese Minors", there are human body dimension data of minors aged 7-10 and 11-12, among which the basic data is taken according to the average size, that is, the 50th percentile P50. Minors aged 7-10: height 132cm, shoulder height 103.8cm, anterior superior iliac spine height 70.4cm, perineum height 56.5cm, upper arm length 24cm; minors aged 11-12: height 146.6cm, shoulder height 116.9cm, anterior superior iliac spine height 80.1cm, perineum height 64.7cm, upper arm length 27.1cm. According to the formula, first calculate the value of A, 7-10 years old minors: A=9.4cm; 11-12 years old minors: A=9.7cm. Then calculate the waist length, for minors aged 7-10: waist length = 13.71cm; for minors aged 11-12: waist length = 14.15cm. Finally, calculate the data of the five zones based on the existing data, for minors aged 7-10: head and neck = 28.2cm, shoulder and back = 19.7cm, waist = 13.7cm, hips = 18.9cm, legs = 51.5cm; for minors aged 11-12: head and neck = 29.7cm, shoulder and back = 22.7m, waist = 14.1cm, hips = 20.4cm, legs = 59.7cm. So for the five-zone independent spring bed net for minors aged 7-12, there are two ways. First, the weights of the two age groups are divided equally, that is, head and neck = 29cm, shoulder and back = 21cm, waist = 14cm, hips = 20cm, and legs = 56cm; second, if among the target population of 7-12 years old, according to actual sales conditions, it is found that sales to minors aged 11-12 account for a higher proportion, then the 11-12 year old population can be given a higher weight, and the final value will also change.

[0148] Here we will explain it by weighted average. After the data of the five zones are obtained, the sum of the data of the five zones is 140cm. The standard length of the mattress is 200cm. The reinforcement system of the edges is 8cm wide and the surrounding strip is 1cm thick. Therefore, for a 200cm long mattress, the actual length of the bed net is only 182cm. Should the remaining 42cm be at the head or the foot? You can make the following considerations:

[0149] Since most pillows for minors are 40 x 60cm in size, it is necessary to ensure that the first area of ​​the bed net can accommodate the width of a pillow so that the second area can correctly correspond to the shoulders and back. Now the head and neck = 29cm, the edge reinforcement is 8cm, and the surrounding strip is 1cm, which adds up to 38cm. Considering that the edge of the pillow is not completely aligned with the edge of the mattress, there will be a certain margin, about 2~3cm, so 5cm is divided into the first area of ​​42cm, and the remaining 37cm is given to the fifth area. The final five-area data is: head and neck = 34cm, shoulders and back = 21cm, waist = 14cm, hips = 20cm, legs = 93cm. For a 182cm long bed net, if the waist diameter of the spring is 6.5cm, there are 29 rows of independent tube springs. It should be noted that due to the slight compression between the springs, the spring with a waist diameter of 6.5cm is actually used in the bed net for about 6.3cm. Therefore, the final number of rows of the five zones is: 5 rows for head and neck (zone 1), 4 rows for shoulders and back (zone 2), 2 rows for waist (zone 3), 4 rows for buttocks (zone 4), and 14 rows for legs.

[0150] In summary, the mattress zoning method provided in this embodiment has the following beneficial effects:

[0151] ① By first determining the waist length and then determining the width of each support partition according to the waist length, the waist length is used as the key parameter for the design of the partitioned mattress, which changes the design method of the prior art of finally determining the length of the waist partition, so that the width of the waist partition is more closely matched with the actual waist length, and the design of the partitioned mattress is more scientific and reasonable, especially improving the support comfort of the waist;

[0152] ② According to the static human body dimensions of different groups of people, three-zone mattresses and five-zone mattress partitioning methods suitable for minors and adults are provided, making the mattress design more targeted and the positioning more accurate;

[0153] ③ Considering the influence of pillow width on the head support area, a method of size compensation for the head and leg areas was proposed to ensure that the pillow can be placed normally and the waist and hips are correctly aligned with the waist position;

[0154] ④ A method for calculating the number of spring rows based on the waist diameter of the independent tube spring and the width of each supporting partition was proposed, which provided a reference for the specific production of mattresses;

[0155] The partition data is based on the national standard big data of Chinese human body dimensions. The data source is authoritative and reliable. The bed net partition data calculated based on this data is more suitable for the Chinese body shape, which is conducive to the development of partitioned mattresses that are truly suitable for the Chinese body dimensions.

[0156] Example 3

[0157] This embodiment provides a bidirectional support mattress for different ages, which can execute the method provided by any embodiment of the present invention and has the corresponding functional modules and beneficial effects of the execution method.

[0158] On the basis of the above-mentioned embodiments, for the features not explained in this embodiment, the explanations in other embodiments are adopted and will not be repeated here.

[0159] See also Figure 8 The different-age bidirectional support mattress provided in this embodiment comprises a waist area 1c for young people, a waist area 1c for old people, and a hip-leg common area 3 located between the waist area 1c for young people and the waist area 1c for old people, wherein the width dimensions of the two waist areas are obtained by the method for determining the waist length of a human body described in Example 1. That is, the width dimensions of the waist area for young people and / or the waist area for old people are determined as follows:

[0160] Obtain several static human dimensions of corresponding age groups;

[0161] According to the static human body dimensions, a distance dimension A from the elbow joint to the end position of the fifth lumbar vertebra L5 is calculated;

[0162] Determine the number of lumbar vertebrae n included in the end position from the elbow joint to the fifth lumbar vertebra L5;

[0163] The waist length dimensions of the five lumbar vertebrae of the corresponding age group are determined according to the distance dimension A and the number of lumbar vertebrae n.

[0164] By using the waist length as the width of the waist region, the widths of the two waist regions, namely the younger waist region 1c and the older waist region 1c, can be determined.

[0165] The different-age bidirectional support mattress provided in this embodiment is, on the one hand, partitioned and designed according to the human body size data of different age groups, and provides two waist zones for young and old people (children sleep at the end with the low-age waist zone 1c, and adolescents sleep at the end with the high-age waist zone 1c). Only by changing the sleeping position, the sleeping support adapted to the age group can be provided at different age stages, making the mattress support more ergonomic, thereby solving the problem that the traditional mattress support structure is single and cannot meet the needs of people of different age groups;

[0166] On the other hand, the distance dimension A corresponding to the length dimension of n lumbar vertebrae is first determined by the existing static human body dimensions, and then the waist length dimensions of the five lumbar vertebrae of the corresponding age group are determined according to the distance dimension A and the number of lumbar vertebrae n. Thus, the waist length dimension that is not explicitly stated in the existing technology can be calculated, so as to provide a reference for the mattress zoning design, thereby improving the comfort of sleep support.

[0167] Therefore, the age-specific bidirectional support mattress provided by the present invention can effectively solve the problems of the single support structure and unscientific partition size design of existing mattresses, thereby improving the comfort of sleep support for teenagers and promoting their sleep health.

[0168] The side of the low-age waist area 1c away from the hip-leg common area 3 is provided with a low-age shoulder and back area 1b and a low-age head and neck area 1a in sequence;

[0169] The elderly waist area 1c is provided with an elderly shoulder and back area 1b and an elderly head and neck area 2a in sequence on one side away from the hip and leg common area 3.

[0170] It should be noted that after the widths of the two waist zones are determined, the sizes of other zones can be determined according to the mattress zone division method provided in Example 2.

[0171] Generally, since the body size of a younger person is smaller than that of an older person, the width of the shoulder and back partition 1b of a younger person is smaller than that of the shoulder and back partition 1b of an older person.

[0172] It should be noted that, consistent with Example 2, in this embodiment, after the width of the head and neck partition is calculated, it is necessary to compensate the width of the head and neck partition according to the total length of the different-age bidirectional support mattress, the pillow width, and the sum of the widths of the partitions. The specific compensation method is shown in Example 2 and will not be repeated here.

[0173] Optionally, the support hardness required for the low-age waist area 1c, the low-age head and neck area 1a, the high-age waist area 1c, and the high-age head and neck area 2a is relatively low, and therefore, low-hardness springs are correspondingly provided;

[0174] The support hardness required by the three parts of the shoulder and back area 1b for young people, the hip and leg common area 3, and the shoulder and back area 1b for old people is relatively high, so high-hardness springs are set accordingly;

[0175] Among them, the support hardness of the low-hardness spring is smaller than the support hardness of the high-hardness spring.

[0176] Furthermore, as a way to adjust the support hardness of the spring, at least one of the waist diameter, wire diameter, and elastic modulus of the spring in different partitions may be made different.

[0177] The following is an example with specific parameters:

[0178] The four body size data (height, shoulder height, height of the anterior superior iliac spine point and upper arm length) of five age groups (4-6 years old, 7-10 years old, 11-12 years old, 13-15 years old, 16-17 years old) of male and female minors were taken out, and the data of A was calculated according to the formula. Then the waist length was calculated. Finally, the data of the four sub-areas of the head and neck, shoulders and back, waist, and hips and legs of the five age groups of men and women were calculated based on the data of height, shoulder height, height of the anterior superior iliac spine point and waist length.

[0179] The five age groups are divided into two age groups, 4-10 years old and 11-17 years old. The four sub-regional data of the two age groups of 4-6 years old and 7-10 years old for boys and girls are averaged; the four sub-regional data of the three age groups of 11-12 years old, 13-15 years old, and 16-17 years old for boys and girls are averaged to get the four sub-regional data of the two age groups of 4-10 years old and 11-17 years old. For underage boys aged 4-10: head and neck = 27.2cm, shoulder and back = 17.9cm, waist = 12.9cm, hip and leg = 63.7cm; for underage girls aged 4-10: head and neck = 27.4cm, shoulder and back = 17.6cm, waist = 12.4cm, hip and leg = 63.4cm;

[0180] For male minors aged 11-17: head and neck = 31.9cm, shoulder and back = 24.5cm, waist = 16.6cm, hip and leg = 87.3cm; for female minors aged 11-17: head and neck = 30.9cm, shoulder and back = 23.5cm, waist = 16.4cm, hip and leg = 84.1cm;

[0181] It can be seen that the data of the four sub-areas of boys and girls in the age group of 4-10 years old are very different. In the age group of 11-17 years old, except for the hips and legs, the data of the remaining parts of boys and girls are within 1cm. Since the bed net structure is mainly to ensure the correct support of the upper body spine, the arrangement of the bed net in the hips and legs has little effect. Therefore, the structural design of the bed net can be universal for different distinctions between boys and girls. Therefore, for minors aged 4-10: head and neck = 27.3cm, shoulder and back = 17.7cm, waist = 12.7cm, hips and legs = 63.6cm; for minors aged 11-17: head and neck = 31.4cm, shoulder and back = 24.0cm, waist = 16.5cm, hips and legs = 85.8cm.

[0182] After obtaining the data of the four sub-areas of the two age groups, the main consideration is the distribution of the head and neck, shoulders and waist on both sides of the bed net for 4-10 years old and 11-17 years old. Special consideration should be given to whether the data of the head and neck need to be adjusted. First, because the size of most pillows for minors is 40×60cm, it is necessary to ensure that the first area on both sides of the bed net can accommodate the width of a pillow, so that the second area can correctly correspond to the shoulders and back. Second, it is necessary to determine whether there is an edge reinforcement system. If there is, the width of the edge reinforcement system needs to be added to the data of the head and neck in the first area, and then determine whether the added data can accommodate the width of a pillow.

[0183] For a 180×200cm mattress, the width of the strip is 1cm. If there is an edge reinforcement system (8cm) around the edges, the actual size of the bed net is 162x182cm in length and width. The head and neck data for the first zone of minors aged 4-10 is 27.3cm, and the head and neck data for the first zone of minors aged 11-17 is 31.4cm. The size of the pillow is 40×60cm. Considering that the edge of the pillow is not completely aligned with the edge of the mattress, there will be a certain margin, about 2-3cm. Therefore, the head and neck data for the first zone plus the edge reinforcement system (8cm) and the strip of 1cm should be 42cm, so the data for the head and neck in the first zone is 33cm. Therefore, for a bed net with an edge reinforcement system, one side is used for the 4-10 years old stage, with the head and neck = 33cm, the shoulders and back = 18cm, and the waist = 13cm; the other side is used for the 11-17 years old stage, with the head and neck = 33cm, the shoulders and back = 24cm, and the waist = 17cm. The remaining 44cm is in the middle of the bed net, which is the hip and leg area in the fourth zone.

[0184] For a 180×200cm mattress, the width of the strip is 1cm, and the thickness of the cotton felt is 0.5cm. If there is no edge reinforcement system (8cm) around the edges, the actual size of the bed net is 177x197cm in length and width. The size of the pillow is 40×60cm. Considering that the edge of the pillow is not completely aligned with the edge of the mattress, there will be a certain margin, about 2-3cm, so the head and neck area of ​​the first zone plus the strip of 1cm should be 42cm. Therefore, for a bed net without an edge reinforcement system, one side is used for 4-10 years old, with the head and neck = 41cm, the shoulders and back = 18cm, and the waist = 13cm; the other side is used for 11-17 years old, with the head and neck = 41cm, the shoulders and back = 24cm, and the waist = 17cm. The remaining 43cm is in the middle of the bed net, which is the hip and leg area of ​​the fourth zone.

[0185] After obtaining the final data of each area, divide the data by the waist diameter of the spring to get the number of independent spring rows in each area. If the waist diameter of the spring is 6.5cm, since the springs will be slightly squeezed against each other, the actual size of the spring with a waist diameter of 6.5cm in the bed net is about 6.3cm. The actual size of the bed net with edge reinforcement system is 162x182cm, and the number of spring rows is 26×29 rows. The specific arrangement of the bed net is as follows Figure 3 As shown; the actual size of the bed net without edge reinforcement system is 177x197cm, the number of spring rows is 29×32 rows, the specific arrangement of the bed net is as follows Figure 8 In this embodiment, after calculation based on specific data, the widths of the young head and neck partition 1a, the young shoulder and back partition 1b, the young waist partition 1c, the hip and leg shared partition 3, the old waist partition 1c, the old shoulder and back partition 1b, and the old head and neck partition 2a are 330mm, 180mm, 130mm, 440mm, 170mm, 240mm, and 330mm, respectively.

[0186] In summary, the age-specific bidirectional support mattress provided in this embodiment has the following beneficial effects:

[0187] ① Adapt to the needs of different age groups: By providing two waist zones for young and old people, the mattress can adapt to the physical changes of children and adolescents at different growth stages. Only by changing the sleeping position, it can provide sleeping support adapted to the age group. It is ergonomic and solves the problem of the single support structure of traditional mattresses.

[0188] ② Scientific and reasonable partition size design: By using static human body size data, first determine the distance dimension A corresponding to the length of n lumbar vertebrae, and then determine the waist length based on A and n, so as to provide a reference for the mattress partition design, make the mattress support more ergonomic, improve the comfort of adolescent sleep support and promote adolescent sleep health.
