Description

Technical Field

[0001] This invention relates to the field of sleep support technology, and more particularly to a two-way support mattress for different age groups. Background Technology

[0002] In the field of mattress design, considering the needs of teenagers, the support structure of the mattress is crucial for their spinal health. However, existing mattress designs on the market have the following shortcomings:

[0003] ① Simple support structure: Most mattresses on the market 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 changeable sleep support during the growth of teenagers, which is not conducive to the sleep health of teenagers.

[0004] ② Unscientific zone design: Partially zoned mattresses can solve the problem of a single support structure, but the traditional zone design of mattresses simply divides the bed net into several uniform areas. This design method does not conform to ergonomics and does not divide the area according to actual human body size data.

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

[0006] Some national standard documents (such as "Anthropometric Dimensions of Chinese Minors" and "Anthropometric Dimensions of Chinese Adults") provide some static anthropometric dimensions for reference. Theoretically, the width dimensions of each support zone can be determined by referring to the above national standard documents, thereby completing the design of the zoned mattress.

[0007] Taking "Anthropometric Dimensions of Chinese Minors" as an example, see... Figure 1 The standard document provides the static anthropometric dimensions for minors, including: height, shoulder height, perineal height, anterior superior iliac spine height, and upper arm length.

[0008] Among them, the static human body dimensions such as height, shoulder height, perineal height, anterior superior iliac spine height, and upper arm length do not require complex technical means such as X-ray imaging. They can be directly obtained by simple measurement on the human body surface and belong to "directly measurable body surface dimensions".

[0009] The lumbar region usually refers to the location of the lumbar vertebrae, 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 both internal structural features of 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 existing national standard documents.

[0010] Since the human waist length cannot be directly obtained, the current method for determining the zoning dimensions of zoned mattresses often involves first determining the lengths of the head zone, back zone, and leg zone based on static human body dimensions, and then using the remaining space as the lumbar zone. In other words, the width of the lumbar zone is determined last, and its matching degree with the actual waist length is low. As a result, the comfort of the lumbar support provided by the zoned mattress determined in this way is also poor.

[0011] In fact, when providing support for different parts of the body during sleep, lumbar support is the most crucial. Therefore, the final design method for determining the length of the lumbar region is extremely unreasonable.

[0012] Therefore, this invention aims to develop a two-way support mattress for different age groups to solve the problems of the single support structure and unscientific zone size design of existing mattresses, thereby improving the comfort of adolescent sleep support and promoting adolescent sleep health.

[0013] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Summary of the Invention

[0014] This invention provides a two-way support mattress for different age groups, which can effectively solve the problems of the single support structure and unscientific zone size design of existing mattresses, thereby improving the comfort of adolescent sleep support and promoting adolescent sleep health.

[0015] To achieve the above objectives, the present invention provides a two-way support mattress for different ages, comprising: a lower age lumbar region, an upper age lumbar region, and a shared hip and leg area located between the lower age lumbar region and the upper age lumbar region, wherein the width of the lower age lumbar region and / or the upper age lumbar region is obtained by a method for determining the human waist length;

[0016] The method for determining the human waist length includes:

[0017] Obtain several static human body dimensions for the corresponding age group;

[0018] Based on the static human body dimensions described above, the distance A from the elbow joint to the termination position of the fifth lumbar vertebra L5 is calculated.

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

[0020] The lumbar length of the five lumbar vertebrae corresponding to the age group is determined based on 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; lumbar length = (5 / 3+5 / 4)·A / 2.

[0022] Optionally, the width of the younger waist region is smaller than the width of the older waist region.

[0023] Optionally, the lower-age waist area is provided with a lower-age shoulder and back area and a lower-age head and neck area on the side away from the common area of ​​hips and legs.

[0024] The elderly waist area is provided with an elderly shoulder and back area and an elderly head and neck area on the side away from the hip and leg common area.

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

[0026] Optional,

[0027] Each of the static human body dimensions mentioned includes 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 section = height - shoulder height;

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

[0031] The width of the waist section equals the length of the waist.

[0032] The width of the hip and leg region is equal to the height of the anterior superior iliac spine.

[0033] Optionally, low-stiffness springs are provided for each of the four sections: the waist section for young children, the head and neck section for young children, the waist section for older children, and the head and neck section for older children.

[0034] High-stiffness springs are installed in the three sections: the shoulder and back area for young children, the shared area for hips and legs, and the shoulder and back area for older children.

[0035] The supporting stiffness of the low-stiffness spring is less than that of the high-stiffness spring.

[0036] Optionally, the springs in different zones may have at least one different waist diameter, wire diameter, or elastic modulus.

[0037] Optionally, the width dimensions of the young child head and neck partition, the young child shoulder and back partition, the young child waist partition, the hip and leg shared partition, the older child waist partition, the older child shoulder and back partition, and the older child 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 two-way support mattress for different age groups:

[0039] ① By providing two lumbar support zones for younger and older children, the mattress can adapt to the physical changes of children and teenagers at different stages of growth. Simply changing the sleeping position can provide age-appropriate sleep support, which is ergonomic and solves the problem of the single support structure of traditional mattresses.

[0040] ② By using static human body size data, the distance dimension A corresponding to the length of n lumbar vertebrae is first determined, and then the waist length dimension is determined based on A and n. This provides 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-dependent bidirectional support mattress provided by this invention can effectively solve the problems of the single support structure and unscientific zone size design of existing mattresses, thereby improving the comfort of adolescent sleep support and promoting adolescent sleep health.

[0065] Example 1

[0066] Please refer to the attached document. Figure 3 This is a flowchart illustrating a method for determining the waist length of a human body according to an embodiment of the present invention. This method is applicable to scenarios requiring the acquisition of waist length dimensions (from the thoracolumbar vertebrae dividing line to the end position of the fifth lumbar vertebra, L5). It can determine the waist length of a human body based on static human body dimensions, providing a reference for mattress zoning design and thus improving the comfort of sleep support. The method specifically includes the following steps:

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

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

[0069] Specifically,

[0070] The static body dimensions of minors that can be directly obtained from "Anthropometric Dimensions of Chinese Minors" include: height, shoulder height, perineal height, anterior superior iliac spine height, and upper arm length.

[0071] The static anthropometric measurements of adults that can be directly obtained from "Chinese Adult Anthropometric Measurements" include: height, shoulder height, upper arm length, perineum height, thigh length, and tibialis point height.

[0072] It should be noted that when obtaining static anthropometric dimensions from "Anthropometric Dimensions of Chinese Minors" and "Anthropometric Dimensions of Chinese Adults", only the 50th percentile (P50) value can be taken. This is because the 50th percentile (P50) size is usually used as a representative of "average" or "medium" size. Designing a zoning system based on P50 data is beneficial to ensure that the resulting zoning is suitable for individuals of "average height" in most populations.

[0073] S102: Based on the static human body dimensions described above, calculate the distance A from the elbow joint to the termination position of the fifth lumbar vertebra L5;

[0074] For minors, the following is based on the "Anthropometric Dimensions of Chinese Minors": Distance dimension A = shoulder height - upper arm length - height of the anterior superior iliac spine;

[0075] For adults, the following is based on the "Anthropometric Dimensions of Chinese Adults": Distance dimension A = shoulder height - upper arm length - (thigh length + tibia point height).

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

[0077] The human spine has 12 thoracic vertebrae and 5 lumbar vertebrae. Anatomically, the termination position of the 12th thoracic vertebra T12 is defined as the dividing point between the thoracic and lumbar vertebrae (thoracolumbar dividing line). Therefore, the total length of the 12 thoracic vertebrae is defined as the shoulder and back length, and the length of the 5 lumbar vertebrae is defined as the waist length dimension.

[0078] When conducting anthropometric measurements, the standard document referenced in "Anthropometric Dimensions of Chinese Minors" and "Anthropometric Dimensions of Chinese Adults" is "GB / T 5703-2010 Basic Anthropometric Items for Technical Design". "GB / T 5703-2010 Basic Anthropometric Items for Technical Design" specifies that the upper arm length is measured as the vertical distance from the acromion to the lower edge of the elbow joint (hereinafter referred to as "elbow joint") at the horizontal flexion point of the forearm.

[0079] See Figure 4 For a typical human anatomy, the starting positions of the anterior superior iliac spine height and thigh length, two static human body dimensions, generally match the location of the fifth lumbar vertebra (L5). However, the ending position of the upper arm length (i.e., at the elbow joint) differs significantly from the starting position of the first lumbar vertebra (L1) (i.e., the thoracolumbar dividing line). Specifically, the elbow joint is clearly lower than the thoracolumbar dividing line. Therefore, the distance A from the elbow joint to the ending position of the fifth lumbar vertebra (L5) is not the actual length of the five lumbar vertebrae; the actual length of the five lumbar vertebrae 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 located between the starting position and the ending position of the second lumbar vertebra L2. Therefore, the number of lumbar vertebrae n included from the elbow joint to the ending position of the fifth lumbar vertebra L5 is 3 (third lumbar vertebra L3 to fifth lumbar vertebra L5) to 4 (second lumbar vertebra L2 to fifth lumbar vertebra L5).

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

[0082] S104: Determine the lumbar length of the five lumbar vertebrae based on the distance dimension A and the number of lumbar vertebrae n.

[0083] Generally, the lengths of the lumbar vertebrae are not significantly different.

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

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

[0086] If half of the people have a distance A of 3 vertebrae from their elbow joint to the L5 vertebra, and the other half have a distance A of 4 vertebrae, then the average of the two distances can be used as a reference for subsequent design.

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

[0088] In summary, the method for determining the human waist length provided in this embodiment first determines the distance dimension A corresponding to the length of n lumbar vertebrae based on existing static human body dimensions, and then determines the waist length of the five lumbar vertebrae based on the distance dimension A and the number of lumbar vertebrae n. This allows for the calculation of waist length dimensions not explicitly stated in existing technologies, providing a reference for mattress zoning design and thereby improving the comfort of sleep support.

[0089] Example 2

[0090] This embodiment provides a mattress partitioning method, which is applicable to application scenarios where the size of each support partition is limited according to the waist length dimensions provided in Embodiment 1. This method can improve the scientificity and rationality of partition size design and further enhance the comfort of sleep support.

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

[0092] S201: Obtain the waist length dimension according to any of the human waist length determination methods described in Example 1;

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

[0094] S202: Determine the width of each support section based on the waist length dimension;

[0095] In this embodiment, the two documents, "Anthropometric Dimensions of Chinese Minors" and "Anthropometric Dimensions of Chinese Adults," provide different static anthropometric dimensions. Therefore, when designing mattress zones:

[0096] ①See Figure 6 The mattress designed based on the static human body dimensions provided in "Chinese Minors' Human Body Dimensions" is a zoned mattress suitable for minors.

[0097] ②See also Figure 7 The mattress designed based on the static human body dimensions provided in "Chinese Adult Anthropometric Dimensions" is a zoned mattress suitable for adults.

[0098] Furthermore, most zoned mattresses currently 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 the head and neck zone (zone 1), the shoulder and back zone (zone 2), the waist zone (zone 3), the hip zone (zone 4), and the leg zone (zone 5).

[0101] Therefore, based on the target population and the number of zones as the dividing criteria, the mattress zoning method in this embodiment can be further refined as follows:

[0102] A. A three-zone mattress zoning method suitable for minors;

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

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

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

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

[0107] At this point, in step S202:

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

[0109] The width of the lumbar and hip area = lumbar length + (anterior superior iliac spine height - perineal height) + transition dimension;

[0110] Leg section width = perineal height - transition dimension;

[0111] The transition dimension is 5cm to 10cm.

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

[0113] At this point, in step S202:

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

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

[0116] The width of the waist section equals the length of the waist.

[0117] The width of the buttock section = height of the anterior superior iliac spine - height of the perineum + transition dimension;

[0118] Leg section width = perineal height - transition dimension;

[0119] The transition dimension is 5cm to 10cm.

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

[0121] At this point, in step S202:

[0122] The width of the head, shoulder and back section = height - waist length - (thigh length + tibia height);

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

[0124] Leg section width = perineal height - transition dimension;

[0125] The transition dimension is 5cm to 10cm.

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

[0127] At this point, in step S202:

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

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

[0130] The width of the waist section equals the length of the waist.

[0131] The width of the hip section = (thigh length + tibialis point height) - perineal height + transition dimension;

[0132] Leg section width = perineal height - transition dimension;

[0133] The transition dimension is 5cm to 10cm.

[0134] It should be noted that the "Anthropometric Dimensions of Chinese Minors" and "Anthropometric Dimensions of Chinese Adults" referenced the national standard document "GB / T 5703-2010 Basic Items for Anthropometric Measurement for Technical Design" when conducting anthropometric measurements.

[0135] GB / T 5703-2010, "Basic Items of Anthropometric Measurement for Technical Design," specifies that the perineal height is measured as the vertical distance from the ground to the area below the pubic symphysis. Since the lower edge of the buttocks (the natural fold where the lower edge of the gluteus maximus meets the posterior thigh) and the area below the pubic symphysis are not on the same horizontal line, the lower edge of the buttocks is lower vertically than the area below the pubic symphysis. Therefore, the height of the lower edge of the buttocks is smaller than the perineal height. Consequently, the perineal height is not equal to the leg length. Furthermore, considering the transitional position of the buttocks, the leg length is calculated by subtracting 5-10 cm from the perineal height (referred to as the "transitional dimension" in this application). Correspondingly, the hip length is calculated by adding 5-10 cm to the formula: height of the anterior superior iliac spine - perineal height (for adults: thigh length + tibialis point height - perineal height). Therefore, the formula for calculating the leg length is: perineal height - transitional dimension.

[0136] S203: Based on the width of the pillow, perform size compensation on the support area corresponding to the head and / or the leg area to determine the final width dimensions of the support area corresponding to the head and / or the leg area.

[0137] In the mattress zoning methods A through D described above, the sum of the widths of each support zone (generally less than 180cm) is usually smaller than the actual length of the mattress net. For example, with a 180×200cm mattress and 1cm wide side rails, if there is an edge reinforcement system (8cm wide) around the perimeter, the mattress net dimensions (width × length) are 162×182cm; if there is no edge reinforcement system (8cm wide), the mattress net dimensions (width × length) are 177×197cm. That is, whether it's 182cm with an edge reinforcement system or 197cm without, the total length will be greater than 180cm. Excess dimensions = Total mattress net length - Sum of the widths of each support zone.

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

[0139] When the width of the support area for the head (i.e., the head, shoulder, and back section or the head and neck section) is smaller than the width of the pillow (the pillow's width is typically 40×60cm or 48×74cm), at least some of the excess space should be allocated to the head support area to ensure the pillow can be placed properly. This ensures the waist, hips, shoulders, and back are correctly aligned with the shoulder or waist position. After ensuring the head support area can accommodate the pillow, the remaining excess space should be allocated to the leg section.

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

[0141] If (width of the support area where the head is located + width of the edge reinforcement system) < width of the pillow, it can be considered that the size of the support area where the head is located is insufficient to fit the pillow, and the excess size should be used to compensate for the support area where the head is located.

[0142] Conversely, if (the width of the support area where the head is located + the width of the edge reinforcement system) > the width of the pillow, then the size of the support area where the head is located can be considered sufficient to fit the pillow, and the excess size can be compensated for in the leg area.

[0143] S204: Calculate the number of rows of independent pocket springs corresponding to each support section based on the waist diameter of the independent pocket springs and the width dimensions of each support section after compensation.

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

[0145] For three-zone mattresses, the firmness of the waist and hips is higher than that of the head, shoulders, back, and legs; for five-zone mattresses, the firmness of the head, neck, waist, and legs is higher than that of the shoulders, back, and hips.

[0146] The following examples illustrate this with specific parameters:

[0147] There is a children's mattress targeting children aged 7-12, and the goal is to design a five-zone independent pocket spring mattress suitable for this age group. First, based on the anthropometric data in GB / T 26158-2010 "Anthropometric Dimensions of Chinese Minors," there are anthropometric data for children aged 7-10 and 11-12, with the average dimensions (50th percentile, P50) used as the base data. For children aged 7-10: height 132cm, shoulder height 103.8cm, anterior superior iliac spine height 70.4cm, perineum height 56.5cm, upper arm length 24cm; for children 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, the value of A is calculated first: for children aged 7-10: A = 9.4cm; for children aged 11-12: A = 9.7cm. Then calculate the waist length: for children aged 7-10: waist length = 13.71cm; for children aged 11-12: waist length = 14.15cm. Finally, calculate the dimensions for the five zones based on the existing data: for children aged 7-10: head and neck = 28.2cm, shoulders and back = 19.7cm, waist = 13.7cm, hips = 18.9cm, legs = 51.5cm; for children aged 11-12: head and neck = 29.7cm, shoulders and back = 22.7cm, waist = 14.1cm, hips = 20.4cm, legs = 59.7cm. Therefore, for children aged 7-12, there are two methods for using a five-zone independent pocket spring mattress. First, if the weights for the two age groups are evenly distributed, then the head and neck = 29cm, shoulders and back = 21cm, waist = 14cm, hips = 20cm, and legs = 56cm. Second, if, based on actual sales data, a higher proportion of the products sold to minors aged 11-12 are found within the target group of 7-12 years old, then the 11-12 year old group can be given a higher weight, and the final values ​​will change accordingly.

[0148] This explanation uses a weighted average approach. After obtaining the data from the five zones, the sum of the data from the five zones is 140cm. The standard length of the mattress is 200cm, the reinforcement system around the four edges is 8cm wide, and the side strips are 1cm thick. Therefore, for a 200cm long mattress, the actual length of the mattress net is only 182cm. The remaining 42cm, whether it should be placed at the head or foot area, can be considered as follows:

[0149] Since most pillows for minors are 40 x 60 cm, it's essential to ensure that Zone 1 of the mattress net can accommodate the width of one pillow, allowing Zone 2 to correctly align with the shoulders and back. Currently, the head and neck area is 29 cm, with 8 cm for edge reinforcement and 1 cm for the side strips, totaling 38 cm. Considering that the pillow edge doesn't perfectly align with the mattress edge, a margin of approximately 2-3 cm is left. Therefore, 5 cm of this 42 cm is allocated to Zone 1, and the remaining 37 cm to Zone 5. The final five-zone dimensions are: Head and Neck = 34 cm, Shoulders and Back = 21 cm, Waist = 14 cm, Hips = 20 cm, Legs = 93 cm. For a 182 cm long mattress net, if the spring waist diameter is 6.5 cm, there are 29 rows of individual pocket springs. Note that due to slight compression between the springs, a spring with a waist diameter of 6.5 cm will actually be used in approximately 6.3 cm of the mattress net. Therefore, the final number of rows for the five zones is as follows: head and neck (zone 1) 5 rows, shoulders and back (zone 2) 4 rows, waist (zone 3) 2 rows, hips (zone 4) 4 rows, and legs (14 rows).

[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 zone based on the waist length, the waist length is used as a key parameter in the design of the zoned mattress. This changes the existing design method of determining the waist zone length last, making the width of the waist zone more consistent with the actual waist length and the design of the zoned mattress more scientific and reasonable, especially improving the support comfort of the waist.

[0152] ② Based on the static body dimensions of different groups, we offer three-zone and five-zone mattresses suitable for minors and adults, making mattress design more targeted and positioning more precise;

[0153] ③ Considering the impact of pillow width on the head support area, a method for size compensation of the head and leg areas is proposed to ensure that the pillow can be placed normally and that 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 individual pocket springs and the width of each support zone was proposed, providing a reference for the specific production of mattresses;

[0155] The zoning data is based on the national standard for Chinese body size big data. The data source is authoritative and reliable. The bed grid zoning data calculated based on this data is more suitable for Chinese body types and is conducive to the development of a zoned mattress that is truly suitable for Chinese body sizes.

[0156] Example 3

[0157] This embodiment provides a two-way support mattress for different ages, which can perform the method provided in any embodiment of the present invention, and has the corresponding functional modules and beneficial effects for performing the method.

[0158] Based on the above embodiments, features not explained in this embodiment are explained using the methods in other embodiments, and will not be repeated here.

[0159] See Figure 8 The age-independent bidirectional support mattress provided in this embodiment includes a lower back section 1c, an upper back section 1c, and a shared hip and leg section 3 located between the lower back section 1c and the upper back section 1c. The width dimensions of both back sections are obtained using the human waist length determination method described in Embodiment 1. That is, the width dimensions of the lower back section and / or the upper back section are determined as follows:

[0160] Obtain several static human body dimensions for the corresponding age group;

[0161] Based on the static human body dimensions described above, the distance A from the elbow joint to the termination position of the fifth lumbar vertebra L5 is calculated.

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

[0163] The lumbar length of the five lumbar vertebrae corresponding to the age group is determined based on the distance dimension A and the number of lumbar vertebrae n.

[0164] By using the waist length as the width dimension of the waist division, the width dimensions of the two waist divisions, namely the young waist division 1c and the old waist division 1c, can be determined.

[0165] The two-way support mattress for different ages provided in this embodiment is designed with different lumbar regions based on the body size data of different age groups. It provides two lumbar regions for younger and older children (children sleep on the end with the younger lumbar region 1c, and teenagers sleep on the end with the older lumbar region 1c). By simply changing the sleeping position, it can provide sleep support that is suitable for different age groups, making the mattress support more ergonomic and solving the problem that the traditional mattress support structure is single and cannot meet the needs of people of different ages.

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

[0167] Therefore, the age-dependent bidirectional support mattress provided by this invention can effectively solve the problems of the single support structure and unscientific zone size design of existing mattresses, thereby improving the comfort of adolescent sleep support and promoting adolescent sleep health.

[0168] The lower-age waist area 1c is provided with a lower-age shoulder and back area 1b and a lower-age head and neck area 1a on the side away from the hip and leg common area 3.

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

[0170] It should be noted that after determining the width dimensions of the two waist sections, the dimensions of other sections can be determined according to the mattress zoning method provided in Example 2.

[0171] Generally, because the body size of younger children is smaller than that of older children, the width of the shoulder and back section 1b of younger children is smaller than that of the shoulder and back section 1b of older children.

[0172] It should be noted that, consistent with Embodiment 2, in this embodiment, after calculating and obtaining the width dimension of the head and neck section, it is necessary to compensate for the width dimension of the head and neck section based on the total length of the multi-age bidirectional support mattress, the pillow width, and the sum of the width dimensions of each section. The specific compensation method is detailed in Embodiment 2 and will not be repeated here.

[0173] Optionally, the four sections of the young waist section 1c, the young head and neck section 1a, the old waist section 1c, and the old head and neck section 2a require lower support stiffness, so low-stiffness springs are provided for each of them.

[0174] The three sections—the shoulder and back section 1b for younger children, the shared section 3 for hips and legs, and the shoulder and back section 1b for older children—require higher support stiffness, therefore, each is equipped with a high-stiffness spring.

[0175] The supporting stiffness of the low-stiffness spring is less than that of the high-stiffness spring.

[0176] Furthermore, as a way to adjust the support stiffness of the spring, at least one of the waist diameter, wire diameter, and elastic modulus of the spring in different zones can be different.

[0177] The following examples illustrate this with specific parameters:

[0178] Take out the four body dimensions (height, shoulder height, anterior superior iliac spine height, and upper arm length) for each of the five age groups (4-6 years, 7-10 years, 11-12 years, 13-15 years, and 16-17 years) for male and female minors. Then calculate the data of A according to the formula. Next, calculate the waist length. Finally, calculate the data of the head and neck, shoulder and back, waist, and hip and leg areas for each of the five age groups for males and females based on the data of height, shoulder height, anterior superior iliac spine height, and waist length.

[0179] The five age groups are further divided into two age groups: 4-10 years old and 11-17 years old. The average of the data from the four sub-regions of the 4-6 and 7-10 year old age groups for both boys and girls, and the average of the data from the four sub-regions of the 11-12, 13-15, and 16-17 year old age groups for both boys and girls, yields the data for the four sub-regions of the 4-10 and 11-17 year old age groups. For boys aged 4-10: head and neck = 27.2cm, shoulders and back = 17.9cm, waist = 12.9cm, hips and legs = 63.7cm; For girls aged 4-10: head and neck = 27.4cm, shoulders and back = 17.6cm, waist = 12.4cm, hips and legs = 63.4cm.

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

[0181] It can be seen that the data for the four zones are very similar for boys and girls aged 4-10. For boys and girls aged 11-17, the data for all areas except the hips and legs are within 1cm. Since the bed net structure primarily ensures proper support for the upper spine, the arrangement of the bed net has little impact on the hips and legs. Therefore, the bed net structure design can be universally applied regardless of whether the child is male or female. Thus, for children aged 4-10: head and neck = 27.3cm, shoulders and back = 17.7cm, waist = 12.7cm, hips and legs = 63.6cm; for children aged 11-17: head and neck = 31.4cm, shoulders and back = 24.0cm, waist = 16.5cm, hips and legs = 85.8cm.

[0182] After obtaining the data for the four zones across the two age groups, the primary consideration is the distribution of the head, neck, shoulders, back, and waist on both sides of the bed net for children aged 4-10 and 11-17. Special attention needs to be paid to whether the head and neck data requires adjustment. Firstly, since most pillows for minors are 40×60cm, it's essential to ensure that zone one on each side of the bed net can accommodate the width of a pillow for zone two to correctly correspond to the shoulders and back. Secondly, it's necessary to determine if there is an edge reinforcement system. If so, the width of the edge reinforcement system should be added to the head and neck data for zone one, and then it should be determined whether this added data can accommodate the width of a pillow.

[0183] For a 180×200cm mattress with a 1cm wide side rail, if there is an 8cm edge reinforcement system around the perimeter, the actual dimensions of the mattress are 162x182cm. The head and neck area measurement for children aged 4-10 is 27.3cm, and for children aged 11-17, it is 31.4cm. The pillow is 40×60cm. Considering that the pillow edge does not perfectly align with the mattress edge, leaving a margin of approximately 2-3cm, the head and neck area measurement plus the 8cm edge reinforcement system and the 1cm side rail should be 42cm, resulting in a head and neck area measurement of 33cm. Therefore, for a mattress with an edge reinforcement system, one side is for children aged 4-10: head and neck = 33cm, shoulders and back = 18cm, waist = 13cm; the other side is for children aged 11-17: head and neck = 33cm, shoulders and back = 24cm, waist = 17cm. The remaining 44cm is in the middle of the mattress, corresponding to the hip and leg area in zone four.

[0184] For a 180×200cm mattress, with a 1cm wide stripe and a 0.5cm thick felt, and without an 8cm edge reinforcement system, the actual dimensions of the mattress net are 177x197cm. The pillow is 40×60cm. Considering the pillow edge doesn't perfectly align with the mattress edge, there will be a margin of approximately 2-3cm. Therefore, the head and neck area plus the 1cm stripe should be 42cm. Thus, for a mattress net without edge reinforcement, one side is for children aged 4-10: head and neck = 41cm, shoulders and back = 18cm, waist = 13cm; the other side is for children aged 11-17: head and neck = 41cm, shoulders and back = 24cm, waist = 17cm. The remaining 43cm is in the middle of the mattress net, which is for the hip and leg area in zone four.

[0185] After obtaining the final data for each region, dividing that data by the spring's waist diameter will give the number of individual coil spring rows for each region. If the spring's waist diameter is 6.5cm, due to slight compression between the springs, a spring with a waist diameter of 6.5cm will actually have a usable spring diameter of approximately 6.3cm in the bed frame. The actual dimensions of the bed frame with an edge reinforcement system are 162x182cm, with 26x29 spring rows. The specific bed frame arrangement is as follows... Figure 3 As shown; the actual dimensions of the bed frame without edge reinforcement system are 177x197cm, with 29×32 rows of springs. The specific arrangement of the bed frame is as follows. Figure 8 As shown. In this embodiment, after calculation based on specific data, the width dimensions 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 older waist partition 1c, the older shoulder and back partition 1b, and the older head and neck partition 2a are 330mm, 180mm, 130mm, 440mm, 170mm, 240mm, and 330mm, respectively.

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

[0187] ① Adaptable to different age groups: By providing two lumbar support zones for younger and older children, the mattress can adapt to the physical changes of children and teenagers at different stages of growth. Simply changing the sleeping position can provide age-appropriate sleep support, which is ergonomic and solves the problem of the single support structure of traditional mattresses.

[0188] ② Scientific and reasonable zoning design: By using static human body size data, the distance dimension A corresponding to the length of n lumbar vertebrae is first determined, and then the waist length dimension is determined based on A and n. This provides a reference for the zoning design of the mattress, making the mattress support more ergonomic, improving the comfort of adolescent sleep support and promoting adolescent sleep health.
