Description

Technical Field

[0001] The invention relates to the technical field of sleeping support, and in particular to a partitioned mattress for optimizing lumbar support. Background Art

[0002] As the demand for healthy sleep increases among middle-aged and elderly people, they have higher requirements for waist support and protection. This is because as people age, the spine may degenerate or deform slightly. If the mattress is too soft and cannot provide enough support, the waist and spine may not maintain a natural curve when sleeping, which may cause or aggravate low back pain and other problems in the long run. A mattress with strong waist support can help middle-aged and elderly people maintain a correct sleeping posture, reduce muscle soreness caused by bad sleeping posture, and thus improve sleep quality.

[0003] Although most of the existing mattresses on the market have a certain degree of comfort, they often lack special designs in terms of lumbar support, which makes it impossible to effectively solve the problem of insufficient lumbar support for middle-aged and elderly people, thereby affecting their sleep quality and physical health. Especially for people with fragile lumbar spines, long-term lack of proper support may lead to increased lumbar pressure, inducing or aggravating low back pain and other problems.

[0004] Although some mattresses currently claim to have zoned support, most of the zone designs are too broad and do not provide precise support designs for the waist.

[0005] 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] Taking "Human Dimensions of Chinese Adults" as an example, see Figure 2 , the standard document gives the static human dimensions of an adult including: height, shoulder height, upper arm length, perineum height, thigh length, shin point height;

[0009] Among them, the above-mentioned static human body dimensions such as height, shoulder height, perineum height, anterior superior iliac spine height, upper arm length, thigh length, and tibial point height 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 surface dimensions."

[0010] 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.

[0011] 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.

[0012] 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.

[0013] Therefore, it is necessary to develop a partitioned mattress that optimizes lumbar support, which can determine the waist length of the human body according to the static human body size, and then scientifically determine the width of the waist zone, thereby improving the comfort of lumbar support and protecting lumbar health.

[0014] 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

[0068] Example 1

[0069] 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:

[0070] S101: Obtaining several static human body dimensions;

[0071] 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.

[0072] Specifically,

[0073] 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;

[0074] 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.

[0075] 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.

[0076] 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;

[0077] 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;

[0078] 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).

[0079] S103: Determine the number n of lumbar vertebrae included in the end position from the elbow joint to the fifth lumbar vertebra L5;

[0080] 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.

[0081] 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").

[0082] 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.

[0083] 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).

[0084] 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.

[0085] S104: Determine the waist lengths of five lumbar vertebrae according to the distance dimension A and the number of lumbar vertebrae n.

[0086] Generally speaking, the lengths of the lumbar vertebrae are not much different:

[0087] 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.

[0088] 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.

[0089] 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:

[0090] Waist length size = (5 / 3+5 / 4)·A / 2=35A / 24.

[0091] 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.

[0092] Example 2

[0093] This embodiment provides a mattress zoning method, which is suitable for application scenarios in which 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.

[0094] See also Figure 5 The mattress partitioning method provided in this embodiment includes the following steps:

[0095] S201: Obtain waist length according to any method for determining waist length of a human body described in Example 1;

[0096] 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.

[0097] S202: Determine the width of each supporting partition according to the waist length;

[0098] 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:

[0099] 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;

[0100] 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;

[0101] Furthermore, currently, most of the zoned mattresses available on the market have a three-zone or five-zone structure.

[0102] Specifically, when it is a three-zone structure, each of the support zones includes a shoulder and back zone (zone one), a waist and hip zone (zone two), and a leg zone (zone three);

[0103] 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).

[0104] 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:

[0105] A. Three-zone mattress partitioning method suitable for minors;

[0106] B. Five-zone mattress partitioning method suitable for minors;

[0107] C. Three-zone mattress partitioning method suitable for adults;

[0108] D. Five-zone mattress zoning method suitable for adults.

[0109] A: Three-zone mattress partitioning method suitable for minors

[0110] At this time, in step S202:

[0111] The width of the shoulder and back area = height - height of the anterior superior iliac spine - waist length;

[0112] The width of the waist and hip area = waist length + (height of the anterior superior iliac spine - height of the perineum) + transition size;

[0113] The width of the leg area = perineum height - transition size;

[0114] Among them, the transition size is 5cm~10cm.

[0115] B: Five-zone mattress partitioning method suitable for minors

[0116] At this time, in step S202:

[0117] The width of the head and neck partition = height - shoulder height;

[0118] The width of the shoulder and back area = shoulder height - height of the anterior superior iliac spine - waist length;

[0119] The width of the waist area = the waist length;

[0120] The width of the buttocks partition = the height of the anterior superior iliac spine - the height of the perineum + the transition size;

[0121] The width of the leg area = perineum height - transition size;

[0122] Among them, the transition size is 5cm~10cm.

[0123] C: Three-zone mattress partition method suitable for adults

[0124] At this time, in step S202:

[0125] The width of the shoulder and back area = height - waist length - (thigh length + shin point height);

[0126] The width of the waist and hip area = waist length + (thigh length + tibia height - perineum height) + transition size;

[0127] The width of the leg area = perineum height - transition size;

[0128] Among them, the transition size is 5cm~10cm.

[0129] D: Five-zone mattress partition method suitable for adults

[0130] At this time, in step S202:

[0131] The width of the head and neck partition = height - shoulder height;

[0132] The width of the shoulder and back area = shoulder height - (thigh length + shin point height) - waist length;

[0133] The width of the waist area = the waist length;

[0134] The width of the buttocks zone = (thigh length + tibia point height) - perineum height + transition size;

[0135] The width of the leg area = perineum height - transition size;

[0136] Among them, the transition size is 5cm~10cm.

[0137] 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;

[0138] 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.

[0139] 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;

[0140] In the above-mentioned mattress partitioning methods A~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 mattress. Taking 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 mattress size width×length is 162×182cm; if there is no edge reinforcement system around (width 8cm), the mattress size width×length is 177×197cm; that is, whether it is 182cm with an edge reinforcement system or 197cm without an edge reinforcement system, it will be greater than 180cm.

[0141] Excess size = total length of mattress - sum of widths of each support partition.

[0142] The excess size can be handled as follows:

[0143] When the width of the support area where the head is located (i.e. the shoulder and back area or the head and neck area) 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 should 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 can be compensated to the leg area.

[0144] 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:

[0145] 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;

[0146] 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.

[0147] It should be noted that the edge reinforcement system specifically refers to a structural design at the edge of the mattress, and its main function is to increase the stability of the mattress and prevent the mattress from being deformed or shifted due to external forces during use. This system usually includes a reinforced edge frame and / or reinforced surrounding strips.

[0148] Reinforced edge frames are usually made of a hard material (such as wood or metal) and are installed around the edges of the mattress to provide additional support and stability. Reinforced gussets are usually made of a soft but somewhat flexible material (such as foam) and are placed around the edges of the mattress to secure and reinforce it.

[0149] This edge reinforcement system can improve the overall durability and service life of the mattress, ensuring that users have a stable and comfortable sleeping experience during use.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] The following is an example with specific parameters:

[0154] 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, hip = 18.9cm, leg = 51.5cm; for minors aged 11-12: head and neck = 29.7cm, shoulder and back = 22.7m, waist = 14.1cm, hip = 20.4cm, leg = 59.7cm. So there are two ways to choose the five-zone independent spring mattress for minors aged 7-12. 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.

[0155] 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 mattress is only 182cm. Should the remaining 42cm be at the head or the foot? You can make the following considerations:

[0156] Since most pillows for minors are 40×60cm in size, it is necessary to ensure that the first zone of the mattress can accommodate the width of a pillow so that the second zone 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 zone of 42cm, and the remaining 37cm is given to the fifth zone. The final data of the five zones is: head and neck = 34cm, shoulder and back = 21cm, waist = 14cm, hips = 20cm, legs = 93cm. For a 182cm long mattress, 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 mattress 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.

[0157] In summary, the mattress zoning method provided in this embodiment has the following beneficial effects:

[0158] 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;

[0159] 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;

[0160] 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;

[0161] 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;

[0162] ⑤ The partition data is based on the national standard big data of Chinese human body dimensions. The data source is authoritative and reliable. The mattress 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.

[0163] Example 3

[0164] This embodiment provides a partitioned mattress for optimizing lumbar support, 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.

[0165] 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.

[0166] See also Figure 8 In the partitioned mattress for optimizing lumbar support provided in this embodiment, the width dimension of the lumbar zone 3 is obtained by the method for determining the human waist length provided in embodiment 1, and the width dimensions of other zones are determined by the mattress partitioning method provided in embodiment 2.

[0167] The partitioned mattress for optimizing lumbar support 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. Thus, the waist length dimension that is not explicitly stated in the existing technology can be calculated, and then the width dimension of the lumbar zone 3 can be scientifically determined, so as to provide a reference for the mattress partition design, thereby improving the comfort of lumbar support and protecting lumbar health.

[0168] Furthermore, when the zoned mattress for optimizing lumbar support provided in this embodiment is mainly designed for middle-aged and elderly people, reference can be made to "D: Five-zone mattress zoning method suitable for adults" in Example 2. At this time, the zoned mattress for optimizing lumbar support is provided with a head and neck zone 1, a shoulder and back zone 2, the waist zone 3, a hip zone 4, and a leg zone 5 from the head of the bed to the foot of the bed.

[0169] The calculation method of the width of each partition is shown in "D: Partitioning method of a five-partition mattress suitable for adults" in the following embodiment 2, and will not be repeated in this embodiment.

[0170] Consistent with Example 2, in this embodiment, after calculating and obtaining the width dimension of the head and neck partition 1, it is necessary to further compensate the width dimension of the head and neck partition 1 according to the total length of the partition mattress for optimizing lumbar support, the width of the edge reinforcement system 6, the pillow width, and the sum of the width dimensions of each partition. The specific compensation method is shown in Example 2 and will not be repeated here.

[0171] In this embodiment, the support hardness of the waist zone 3 is greater than the support hardness of the head and neck zone 1 and the leg zone 5; the support hardness of the head and neck zone 1 and the leg zone 5 is greater than the support hardness of the shoulder and back zone 2 and the hip zone 4.

[0172] The waist is the key part that bears the weight of the whole body, so the support must be strong enough to avoid the waist from sinking or abnormal curvature. This design can reasonably set the support hardness of the mattress according to the physiological needs of different parts of the human body, thereby improving overall comfort and health.

[0173] As an optional support hardness adjustment method, the waist diameter and / or wire diameter of the springs in different partitions can be different. Specifically, the waist diameter and / or wire diameter of the springs can be adjusted according to the support requirements of different partitions, thereby improving the support effect and comfort of the mattress.

[0174] For example, a spring with a smaller waist diameter is used in the middle position of the waist area 3, thereby increasing the number of springs per unit area (ie, increasing the spring density), which helps to enhance the support force of the waist.

[0175] In this embodiment, a high-hardness spring 301 is provided in the middle of the waist area 3, and a transition spring 302 is provided at the waist area near the shoulder and back area 2 and the hip area 4; wherein the waist diameter of the high-hardness spring 301 is smaller than the waist diameter of the transition spring 302. The transition spring 302 can adjust the hardness difference between the two areas, making the hardness transition of the entire mattress smoother, avoiding too abrupt transition, and increasing comfort.

[0176] Optionally, in this embodiment, the waist diameters of the springs of the head and neck area 1, the shoulder and back area 2, and the leg area 5 are 6.5 cm, the waist diameter of the transition spring 302 is 5.0 cm, and the waist diameter of the high hardness spring 301 is 3.5 cm;

[0177] The spring wire diameter of the head and neck partition 1 and the leg partition 5 is 2.0mm, the wire diameter of the shoulder and back partition 2, the hip partition 4 and the transition spring 302 is 1.8mm; the wire diameter of the high hardness spring 301 is 1.4mm.

[0178] The following is an example with specific parameters:

[0179] A zoned mattress with optimized lumbar support designed for adults aged 32-45. First of all, for adults aged 32-45, GB / T 10000-2023 "Human Dimensions of Chinese Adults" is based on the national adult human dimension survey conducted from 2014 to 2018, which has been 6-10 years. If you need to design a mattress for adults aged 32-45, the corresponding age group in GB / T 10000-2023 "Human Dimensions of Chinese Adults" should be 26-35 years old, and the basic data should be taken according to the average size, which is the 50th percentile P50. Adult males aged 26-35: height 170.6cm, shoulder height 138.4cm, thigh length + tibia height 92.1cm, perineum height 73.5cm, upper arm length 31.8cm; adult females aged 26-35: height 158.8cm, shoulder height 128.6cm, thigh length + tibia height 85.4cm, perineum height 70.3cm, upper arm length 29.2cm. According to the formula, first calculate the value of A, adult males aged 26-35: A=14.5cm; adult females aged 26-35: A=14cm. Then calculate the waist length, adult males aged 26-35: waist length = 21.15cm; adult females aged 26-35: waist length = 20.42cm. Finally, we calculated the data of the five zones based on the existing data. For adult males aged 26-35, the head and neck are 32.2 cm, the shoulders and back are 25.15 cm, the waist is 21.15 cm, the hips are 28.6 cm, and the legs are 63.5 cm. For adult females aged 26-35, the head and neck are 31.2 cm, the shoulders and back are 23.96 cm, the waist is 20.78 cm, the hips are 26.85 cm, and the legs are 61.9 cm. This mattress does not distinguish between males and females. The data of the two are added and averaged to obtain the final five-zone data: head and neck = 31 cm, shoulders and back = 24 cm, waist = 21 cm, hips = 27 cm, and legs = 62 cm.

[0180] After the data of the five zones are obtained, the sum of the data of the five zones is 165cm. 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 mattress is only 182cm. Should the remaining 17cm be compensated for the head or the feet? The following considerations can be made:

[0181] Since most adult pillows are 40×60cm in size, it is necessary to ensure that the first zone of the mattress can accommodate the width of a pillow so that the second zone can correctly correspond to the shoulders and back. Now the head and neck = 31cm, the edge reinforcement is 8cm, and the surrounding strip is 1cm, which adds up to 40cm. Considering that the edge of the pillow and the edge of the mattress are not completely aligned, there will be a certain margin of about 2~3cm. Therefore, 2cm of the 17cm is divided into the first zone, and the remaining 15cm is given to the fifth zone. The final five-zone data is: head and neck = 33cm, shoulders and back = 24cm, waist = 21cm, hips = 27cm, legs = 77cm.

[0182] The three waist diameters of the springs are: the waist diameter of the springs of the head and neck, shoulder and back, and legs is 6.5 cm, the waist diameter of the waist transition spring 302 is 5.0 cm, and the waist diameter of the waist high-density spring is 3.5 cm. The final spring arrangement is as follows: Figure 8 shown.

[0183] In summary, the partitioned mattress for optimizing lumbar support provided in this embodiment has the following beneficial effects:

[0184] ① Optimize the partitioned mattress for lumbar support. By obtaining the static human body dimensions, calculate the distance A from the elbow joint to the end position of the fifth lumbar vertebra L5, determine the number of lumbar vertebrae n included in the end position from the elbow joint to the fifth lumbar vertebra L5, and then determine the waist length dimensions of the five lumbar vertebrae;

[0185] ② According to the physiological needs of different parts of the human body, reasonably set the support hardness of the mattress to improve overall comfort and health;

[0186] ③ Using a spring with a smaller waist diameter in the middle position of the waist zone 3 increases the number of springs per unit area, which helps to enhance the support force of the waist.

[0187] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
