Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to a support airbag and a mattress. Background Technology

[0002] Existing mattresses contain cubical support airbags, which are laid out sequentially to form a flat support surface. Each airbag has a vertically penetrating perforation in its center, serving both as a ventilation channel and, through the sidewalls of the perforation, limiting excessive expansion at the top and bottom walls of the airbag and ensuring it effectively maintains its cubic shape. However, the perforations on existing support airbags have a uniform layout, resulting in identical support performance across all areas. This lack of differentiation based on the user's body shape and overall comfort reduces comfort and negatively impacts the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a support airbag and mattress. By setting through holes with a differentiated layout on the airbag body, the airbag body obtains differentiated support characteristics to meet the differentiated support requirements of different body parts of the user and improve the user experience.

[0004] This invention is achieved through the following method: a support airbag includes a cubic body with a vertically penetrating through-hole in the center. The airbag achieves differentiated support by incorporating these differentiated through-holes. By providing these differentiated through-holes, the airbag acquires differentiated support characteristics to meet the varying support requirements of different body segments, thus improving the user experience. Specifically, the more through-holes per unit area on the top wall of the airbag, the softer the airbag; conversely, the fewer through-holes per unit area on the top wall of the airbag, the harder the airbag.

[0005] Preferably, the through holes are symmetrically arranged on both sides along the length of the bladder, and the through holes on the bladder are arranged symmetrically from left to right, so as to ensure that the user can obtain balanced support on both sides of the same torso, thereby improving lying comfort and preventing the user from feeling a difference due to the difference in support on both sides of the same torso, thus improving the lying experience.

[0006] Preferably, the through holes are evenly spaced along the centerline of the airbag, and there are at least two through holes. This arrangement ensures balanced support across the central region of the airbag. The through holes, positioned along the centerline, enhance support performance and guide vertical expansion and contraction on both sides of the centerline.

[0007] Preferably, the through holes include three front holes along the front edge of the cyst body, three rear holes along the rear edge of the cyst body, and two central holes along the center line of the cyst body. The front and rear holes are aligned front-to-back, while the front and central holes are staggered front-to-back. The front, central, and rear holes are arranged front-to-back to ensure that through holes are provided at the front, middle, and rear edges of the top wall of the cyst body. There are three front and three rear holes, and two central holes, arranged left-to-right to ensure that there are through holes on the left, middle, and right sides of the cyst body. The increased number of through holes provides soft support.

[0008] Preferably, the diameter of the through hole is A, 70mm≤A≤90mm, which ensures smooth airflow and provides a pulling force to the corresponding areas of the top and bottom walls of the bladder, preventing excessive deformation in the middle of the bladder. Excessive deformation includes excessive bulging and excessive contraction.

[0009] As a preferred option, the axial spacing between adjacent through holes is B, with 150mm≤B≤180mm. This ensures that the density of the through holes meets the usage requirements and that the reserved area between adjacent through holes meets the support requirements, preventing the bladder from being affected by the excessive density of through holes, thus ensuring the reliability of the support.

[0010] Preferably, the sidewall of the through-hole is formed by repeated radial bending to create alternating vertical annular outer and inner corners. These outer and inner corners guide the vertical reciprocating expansion and contraction of the sidewall, allowing for smooth rise and fall of the top wall of the bladder. The serrated structure formed by the outer and inner corners facilitates expansion and contraction along the through-hole axis, guiding deformation and effectively maintaining the sidewall's contour. This enhances vertical support performance and prevents collapse of the bladder's central portion due to vertical stress.

[0011] A mattress includes a mattress body comprising support airbags and an outer cover enclosing the airbags. The support airbags are arranged side-by-side from front to back and formed into zones with differentiated support characteristics through a differentiated perforation layout. The sequential arrangement of the support airbags with differentiated perforation layouts allows each airbag to have different support characteristics, meeting the diverse support needs of different body segments of the user. The outer cover encloses the support airbags, providing positioning and protection.

[0012] Preferably, the partitions include a head area, a back area, a hip area, a leg area, and a foot area. This not only provides corresponding support for each segment of the user's body but also allows for the customization of the number and layout of through-holes based on the support needs of each segment, effectively improving lying comfort. By providing different layouts and numbers of through-holes in each partition, different support characteristics can be achieved in each partition under the same air pressure, eliminating the need for independent control of each partition, effectively simplifying the control procedure and improving operational convenience.

[0013] Preferably, the number of through holes in the lumbar region is greater than the number of through holes in the head region. Under the same air pressure, the lumbar region is softer than the head region, so that the lumbar region can deform to match and conform to the user's lumbar and back, thereby improving support comfort.

[0014] Preferably, the head area, leg area, and foot area have the same number of through holes, and the head area, leg area, and foot area have the same number and layout of through holes, so that the three areas can share the same structure of support airbags. By sharing support airbags, production costs are reduced, and by reducing the types of support airbags, users can easily select and assemble them on-site as needed, thus meeting the differentiated usage needs of different users.

[0015] Preferably, the number of through holes in the head area is greater than the number of through holes in the buttocks area. Under the same air pressure, the head area is softer than the buttocks area, so that the buttocks area can receive firmer support.

[0016] Preferably, the length of the support airbag corresponds to the width of the pad, so that the support airbags are arranged side by side along the length of the pad to form the support surface of the pad. The fact that the length of the support airbag is the same as the width of the pad allows the support airbags to be arranged front-to-back to form a flat support surface of the pad. This ensures a flat support surface, improves lying comfort, and effectively reduces the number of support airbags. Reducing seams improves flatness and facilitates assembly and use.

[0017] The beneficial effects of this utility model are: by setting through holes with a differentiated layout on the bladder, the bladder can obtain differentiated support characteristics to meet the differentiated support requirements of different body parts of the user and improve the user experience.

[0026] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1:

[0028] This embodiment provides a support airbag.

[0029] like Figure 1 The illustrated support airbag includes a cubic body with a vertically penetrating through-hole 1 in the center. The airbag achieves differentiated support by incorporating these differently arranged through-holes 1. By providing these differentiated through-holes 1 on the airbag body, the airbag acquires differentiated support characteristics to meet the varying support requirements of different body segments, thereby improving the user experience.

[0030] In this embodiment, the top surface of the bladder can be provided with through holes 1 in different layouts and numbers as needed. By setting through holes 1, the softness and hardness of the bladder can be adjusted, so that each bladder can maintain a difference in softness and hardness under synchronous air pressure adjustment. This not only meets the differentiated support needs of different body parts of the user, but also simplifies the air path control structure by uniformly adjusting the air pressure, thereby reducing costs and facilitating operation.

[0031] In this embodiment, the through holes 1 are symmetrically arranged on both sides along the length of the bladder body, and the through holes 1 are equidistantly distributed along the centerline of the bladder body. There are at least two through holes 1, so that the bladder body can have a variety of through hole 1 numbers and layout structures, including but not limited to the following structures:

[0032] Structure 1, such as Figure 2 and 3 As shown, the capsule has two through holes 1, which are located on both sides of the capsule along the center line to give the capsule a relatively rigid support characteristic.

[0033] Structure 2, such as Figure 4As shown, the capsule has three through holes 1, which are equidistantly distributed along the center line of the capsule, so that the top wall of the capsule has a layout of through holes 1 symmetrically arranged along its length, so that the capsule has moderate support characteristics.

[0034] Structure 3, such as Figure 5 and 6 As shown, the through hole 1 includes three front holes 3 distributed along the front edge of the bladder body, three rear holes 4 distributed along the rear edge of the bladder body, and two central holes 2 distributed along the center line of the bladder body. The front holes 3 and rear holes 4 are aligned front to back, and the front holes 3 and central holes 2 are staggered front to back. The bladder body has eight through holes 1 distributed in a dispersed manner, which makes the bladder body have a softer support characteristic.

[0035] By flexibly combining the above three support structures, the different support needs of users at various body segments can be met. Furthermore, the support structure can also be configured with various through-hole layouts as needed, all of which should be considered specific implementations of this embodiment.

[0036] In this embodiment, the diameter of the through hole 1 is A, where 70mm ≤ A ≤ 90mm. Preferably, A = 80mm. This ensures that the diameter of the through hole 1 meets the air permeability requirements and also limits the corresponding areas of the top and bottom walls of the bladder, preventing excessive deformation of the middle part of the bladder during inflation and deflation. Furthermore, parameter A can also be 70mm, 75mm, 85mm, 90mm, etc., and any value meeting the specified requirements should be considered a specific implementation of this embodiment.

[0037] In this embodiment, the axial spacing between adjacent through holes 1 is B, where 150mm ≤ B ≤ 180mm. Preferably, B = 160mm. This ensures a large connection area between the top wall of the bladder and the periphery of adjacent through holes 1, effectively supporting the user and ensuring balanced support across the central area of ​​the bladder. Furthermore, parameter B can also be 150mm, 155mm, 165mm, 180mm, etc., and any value meeting these requirements should be considered a specific implementation of this embodiment.

[0038] In this embodiment, the sidewall of the through hole 1 is formed by radially and repeatedly bending to create vertically alternating annular outer corners 5 and annular inner corners 6. The outer corners 5 and inner corners 6 guide the vertical reciprocating expansion and contraction of the sidewall of the through hole 1 through opening and closing switching, so that the top wall of the bladder can rise and fall smoothly. The sidewall of the through hole 1 is divided into multiple annular regions from top to bottom. The center of each annular region is formed by radially inward concavity or radially outward bulge to create annular inner corners 6 and outer corners 5. The inner corners 6 and outer corners 5 are alternately arranged along the axis of the through hole 1, so that the vertical cross-sectional profile of the sidewall of the through hole 1 is a radially reciprocating W-shape. During use, the corners on the sidewall of the bladder can be opened and closed freely, allowing the sidewall of the bladder to deform vertically. This ensures that the height of the sidewall of the through hole 1 matches the thickness of the middle part of the bladder, ensuring that the middle part of the bladder always receives vertical support and that the sidewall of the through hole 1 will not undergo irreversible deformation due to excessive vertical deformation of the middle part of the bladder. This ensures that the sidewall of the through hole 1 can achieve vertical expansion and contraction in a preset manner.

[0039] Example 2:

[0040] Compared to Embodiment 1, this embodiment provides a mattress.

[0041] like Figure 7 The mattress shown includes the support airbags 13 and an outer cover 7 that surrounds the support airbags 13. Multiple support airbags 13 are joined together in a front-to-back direction to form a support pad. The outer cover 7 protects and positions the support airbags 13, ensuring that the relative positions of the support airbags 13 are fixed and that they are joined together to form a flat support surface. It also prevents the support airbags 13 from being damaged by impacts from sharp objects.

[0042] In this embodiment, the support airbags 13 are arranged side by side from front to back and combined to form zones with differentiated support by setting differentiated through holes 1. The zones include a head zone 8, a back zone 9, a hip zone 10, a leg zone 11, and a foot zone 12. Each zone obtains differentiated support by setting differentiated through holes 1, thereby meeting the usage needs of users in different body parts.

[0043] In this embodiment, the lumbar region 9 uses a support airbag 13 with structure three to obtain flexible support, the head region 8, leg region 11 and foot region 12 use support airbags 13 with structure two to obtain moderate support, and the hip region 10 uses support airbags 13 with structure one to obtain rigid support. The number of through holes 1 in the lumbar region 9 is greater than the number of through holes 1 in the head region 8. The head region 8, leg region 11 and foot region 12 have the same number of through holes 1. The number of through holes 1 in the head region 8 is greater than the number of through holes 1 in the hip region 10, so that the support characteristics of each zone meet the support requirements of the corresponding torso segment.

[0044] In this embodiment, the length of the support airbag 13 corresponds to the width of the pad, so that the support airbags 13 are arranged side by side along the length of the pad to form the support surface of the pad. The length of the support airbag 13 is the same as the width of the pad, so that the support airbags 13 only need to be laid in the front-to-back direction to be assembled to form the support pad, thereby meeting the needs of mattress use, effectively simplifying the structure and improving assembly efficiency.

[0045] The structure and effect of the supporting airbag described in this embodiment are the same as those in Embodiment 2, and will not be repeated here.
