Description

Technical Field

[0001] The utility model relates to the field of bedding, in particular to a supporting air bag and a mattress. Background Art

[0002] Existing mattresses are equipped with cubical support airbags, which are laid out in sequence to form a flat support surface. A vertical through-hole is provided in the middle of the support airbag, and the side walls of the through-hole are repeatedly bent radially to form corners, so that the side walls of the through-hole have a multi-layer folding structure, which not only provides a breathable passage, but also utilizes the vertical expansion and contraction of the through-hole sidewalls to limit excessive deformation of the top and bottom walls of the support airbag, ensuring that the support airbag effectively maintains its cubical profile. The through-holes on existing support airbags have the same structure, including the same corners and the same number of folding layers, so that the airbags have the same support performance, and cannot obtain differentiated support according to the needs of different body parts of the user, resulting in reduced support comfort and affecting the user experience. Utility Model Content

[0003] In order to address the deficiencies of the prior art, the present invention provides a support airbag and a mattress. By providing through holes with differentiated structures on the airbag body, the airbag body obtains differentiated support characteristics to meet the differentiated support requirements of different torso segments of the user and enhance the user experience.

[0004] This utility model is achieved through the following method: a support airbag comprising a bladder body, a vertical through-hole provided in the middle of the bladder body, and a sidewall of the through-hole formed by repeated radial bending to form a corner portion. The through-hole is provided with different angles of the corner portion to obtain a different number of folding layers, thereby providing the bladder with differentiated support. By providing through-holes with differentiated structures in the bladder body, the number of folding layers of the sidewalls of the through-hole is changed by adjusting the angle of the corner portion, thereby achieving differentiated support, meeting the differentiated usage needs of users of different body parts and improving the user experience.

[0005] Preferably, the through-holes include hard holes, neutral holes, and flexible holes formed by different corner angles. By setting different corner angles, different numbers of folds are achieved at the same through-hole sidewall height, thereby achieving different support properties. This creates hard holes, neutral holes, and flexible holes for adjusting the hardness of the bladder. Smaller corner angles increase the number of folds and make the bladder softer; larger corner angles reduce the number of folds and make the bladder harder.

[0006] Preferably, the corner angle in the hard hole is A, 105°≤A≤150°, and the vertical deformation resistance of the hard hole is improved by increasing the corner angle, providing hard support for the middle part of the capsule.

[0007] Preferably, the corner angle in the neutral hole is B, 65°≤B<105°. The angle of the corner is moderate, which can not only provide effective support for the middle part of the capsule, but also improve the deformation performance of the middle part of the capsule, ensuring that the top wall of the capsule can fit the user's surface through its own deformation.

[0008] Preferably, the corner angle in the flexible hole is C, 30°≤C<65°, and the side wall of the through hole has more folding layers, so that the middle part of the sac has better softness, providing comfortable support for the user.

[0009] Preferably, the bladder is cubical in shape, with the through-holes symmetrically arranged along the length of the bladder. There are at least two through-holes, equidistantly spaced along the centerline of the bladder. The cubical bladder has a regular contour, facilitating quick assembly and disassembly, while also allowing for tight assembly to form a flat support surface, effectively minimizing gaps between adjacent bladders and enhancing sleeping comfort.

[0010] Preferably, the corner portion includes outer corners and inner corners alternately arranged along the axis of the through hole, and the outer corners and the inner corners cooperate to open and close and guide the expansion and contraction of the through hole side wall. The through hole side wall forms a serrated structure by arranging the outer corners and the inner corners, which not only facilitates the expansion and contraction of the through hole side wall along the axis of the through hole by opening and closing the corner portions, but also guides the deformation of the through hole side wall, so that the top wall of the capsule can be raised and lowered smoothly, and can also effectively maintain the profile of the through hole side wall, thereby improving the vertical support performance and preventing the middle part of the support capsule from collapsing due to vertical force.

[0011] Preferably, the outer corner and the inner corner in the same through hole have the same angle, ensuring that each section of the through hole side wall has balanced deformation resistance, ensuring that each section of the through hole side wall can deform synchronously, and preventing the through hole from bending its axis due to local excessive deformation of the side wall.

[0012] A mattress comprises a cushion body, the cushion body including support air cells and an outer cover enclosing the support air cells. The support air cells are arranged side by side from front to back and are provided with through holes having different corner angles to form zones with differentiated support properties. The support air cells are arranged in a front-to-back sequence and provided with through holes having different corner angles, so that each support air cell has different support characteristics to meet the differentiated support needs of different body parts of the user. The outer cover encloses the support air cells, positioning and protecting them.

[0013] Preferably, the zones include head, back, hip, leg, and foot areas, providing support for each segment of the user's body. The through-hole structure can be customized based on the support requirements of each segment, effectively enhancing reclining comfort. By providing through-holes with differentiated corner angles and folding layers in each zone, each zone achieves different support characteristics under the same air pressure, eliminating the need for independent control of each zone. This simplifies the control process and improves operational convenience.

[0014] Preferably, the corner angle of the waist and back area is smaller than the corner angle of the head area, so that the number of folded layers of the through-hole side walls in the waist and back area is greater than the number of folded layers of the through-hole side walls in the head area. Under the same air pressure, the waist and back area is softer than the head area, so that the waist and back area can match and fit the user's waist and back through deformation, thereby improving support comfort.

[0015] Preferably, the head area, leg area and foot area have the same corner angle, so that the number of folded layers of the through-hole side walls of the head area, leg area and foot area are the same, and the head area, leg area and foot area have the same through-hole structure, so that the three areas can share the support airbags of the same structure. The production cost is reduced by sharing the support airbags, and the types of support airbags are reduced to facilitate users to select and assemble on-site according to their needs at the purchase site, thereby meeting the differentiated usage needs of different users.

[0016] Preferably, the angle of the corners in the head area is smaller than that in the hip area, so that the number of folded layers of the through-hole sidewalls in the head area is greater than that in the hip area. Under the same air pressure, the head area is softer than the hip area, and the hip area can obtain firmer support.

[0017] Preferably, the length of the support airbags corresponds to the width of the cushion body, so that the support airbags are arranged side by side along the length of the cushion body to form the cushion body's support surface. The length of the support airbags is equal to the width of the cushion body, so that the support airbags can be arranged in a front-to-back direction to form a flat support surface for the cushion body. This not only ensures a flat support surface and improves lying comfort, but also effectively reduces the number of support airbags, improves flatness by reducing splicing gaps, and facilitates assembly and use.

[0018] The beneficial effects of the present invention are as follows: a through hole with a differentiated structure is provided on the sac body, and the number of folding layers of the side wall of the through hole is changed by adjusting the angle of the corner portion, thereby obtaining differentiated support, meeting the differentiated usage needs of different body parts of the user, and improving the user experience.

[0028] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0029] Example 1:

[0030] This embodiment provides a support airbag.

[0031] like Figure 1 The support airbag shown includes a bladder body with a vertical through-hole in the middle. The sidewalls of the through-hole are repeatedly bent radially to form corners. The through-holes have different corner angles to achieve different folding layers, thus providing differentiated support for the bladder. By providing through-holes with differentiated structures on the bladder body and adjusting the corner angles to change the number of folding layers of the through-hole sidewalls, differentiated support is achieved, meeting the differentiated needs of users of different body types and enhancing the user experience.

[0032] In this embodiment, the top surface of the sac can be provided with through holes with differentiated structures as needed. By providing through holes with different structures to adjust the softness and hardness of the sac, each sac can maintain a difference in softness and hardness when the air pressure is adjusted synchronously, which not only meets the differentiated support needs of different torso sections of the user, but also simplifies the air path control structure by uniformly adjusting the air pressure, thereby reducing costs and facilitating operation.

[0033] In this embodiment, the through hole is provided with a corner portion with a differentiated angle so that the side wall of the through hole obtains a differentiated number of folding layers at the same height, thereby making the through hole have differentiated support. The through hole includes a hard hole 2, a neutral hole 3 and a flexible hole 4 formed by setting differentiated corner angles. The support performance of the sac is adjusted by setting a through hole with differentiated support.

[0034] In this embodiment, the corner angle of the hard hole 2 is A, 105°≤A≤150° (e.g. Figure 2 As shown, the two sides of the corner portion are perpendicular to each other, making the sidewalls of the through-hole more resistant to vertical deformation, thereby providing rigid support for the middle portion of the capsule, ensuring good rigidity. Parameter A can be 105°, 120°, 135°, 150°, etc., and any angle that meets the preset requirements should be considered a specific implementation of this embodiment.

[0035] In this embodiment, the corner angle of the neutral hole 3 is B, 65°≤B<105° (e.g. Figure 3 and 4 The angle between the two sides of the corner portion is moderate, ensuring moderate vertical deformation resistance of the through-hole sidewalls and providing moderate support for the central portion of the capsule. Parameter B can be 65°, 70°, 90°, 105°, and so on. Any such parameter that meets the preset requirements should be considered a specific implementation of this embodiment.

[0036] In this embodiment, the corner angle of the flexible hole 4 is C, 30°≤C<65° (e.g. Figure 5 and 6 (As shown), the angle between the two sides of the corner portion is relatively small, resulting in weaker vertical deformation resistance of the through-hole sidewalls. This makes the central portion of the bladder relatively soft, allowing it to deform to conform to the user's surface, improving comfort in the central portion of the bladder. Parameter C can be 30°, 40°, 55°, 65°, and so on. Any implementation that meets the preset requirements should be considered a specific embodiment of this embodiment.

[0037] In this embodiment, the sidewall of the through hole is repeatedly bent radially to form an annular outer corner 5 and an annular inner corner 6, which are vertically alternatingly arranged. The outer corner 5 and the inner corner 6 are switched on and off to guide the vertical reciprocating expansion and contraction of the through hole sidewall, thereby smoothly raising and lowering the top wall of the capsule. The sidewall of the through hole is divided into multiple annular regions from top to bottom. The central portion of each annular region is formed by radially inward depression or radially outward bulge to form annular inner corner 6 and outer corner 5. The inner corner 6 and the outer corner 5 are alternately arranged along the axis of the through hole, so that the vertical cross-sectional profile of the through hole sidewall is a radially reciprocating W-shape. During use, the corners on the side walls of the sac can be opened and closed freely, so that the side walls of the sac can be vertically expanded and contracted, ensuring that the height of the side walls of the through hole matches the thickness of the middle part of the sac, ensuring that the middle part of the sac can always obtain vertical support, and ensuring that the side walls of the through hole will not undergo irreversible deformation due to excessive vertical deformation of the middle part of the sac, ensuring that the side walls of the through hole can achieve vertical expansion and contraction in a preset manner.

[0038] In this embodiment, the outer corner 5 and the inner corner 6 in the same through hole have the same angle, which ensures that the outer corner 5 and the inner corner 6 have the same deformation resistance, so that the sections of the through hole side wall can deform synchronously after being subjected to force, thereby ensuring that the through hole expands and contracts along its axial direction and guiding the vertical expansion and contraction deformation of the middle area of ​​the capsule.

[0039] In this embodiment, the through holes are symmetrically arranged on both sides along the length direction of the capsule, and the through holes are equidistantly spaced along the center line of the capsule. There are at least two through holes, so that the capsule can have a variety of through hole numbers and layout structures.

[0040] In this embodiment, the capsule is in a cubic shape, which facilitates the splicing of the capsules and effectively reduces the gap between adjacent capsules. It not only effectively eliminates the foreign body sensation, but also ensures that the top surfaces of the capsules are flush and spliced ​​to form a flat supporting surface, providing comfortable support for the user.

[0041] Example 2:

[0042] Compared with the first embodiment, this embodiment provides a mattress.

[0043] like Figure 7 The mattress shown includes a cushion body, which includes support air cells 1 and a cover 7 that encloses the support air cells 1. Multiple support air cells 1 are assembled front-to-back to form a support cushion. The cover 7 protects and positions the support air cells 1, ensuring that the relative positions of the support air cells 1 are fixed and that they form a flat support surface. It also prevents the support air cells 1 from being damaged by external sharp objects.

[0044] In this embodiment, the support airbags 1 are arranged side by side from front to back and have through-holes with different corner angles to form zones with differentiated support. These zones include a head zone 8, a waist and back zone 9, a hip zone 10, a leg zone 11, and a foot zone 12. Each zone achieves differentiated support through the differentiated through-hole structure, thereby meeting the needs of different body parts of the user.

[0045] In this embodiment, if Figure 8 As shown, the support airbag 1 forming the waist and back area 9 uses flexible holes 4, so that the middle part of the support airbag 1 has a smaller hardness, ensuring that the middle part of the support airbag 1 fits the user's waist and back through deformation, ensuring the support comfort, the support airbag 1 forming the head area 8, the leg area 11 and the foot area 12 uses neutral holes 3, so that it obtains moderate support performance, and the support airbag 1 forming the buttocks area 10 uses hard holes 2, so that the middle part of the support airbag 1 has a larger hardness, providing effective support for the user's buttocks. Specifically, the corner angle of the waist and back region 9 is smaller than the corner angle of the head region 8, so that the number of folded layers of the through-hole side walls of the waist and back region 9 is greater than that of the through-hole side walls of the head region 8; the head region 8, leg region 11, and foot region 12 have the same corner angle, so that the number of folded layers of the through-hole side walls of the head region 8, leg region 11, and foot region 12 is the same; the corner angle of the head region 8 is smaller than the corner angle of the hip region 10, so that the number of folded layers of the through-hole side walls of the head region 8 is greater than that of the through-hole side walls of the hip region 10. In addition, the through-hole structure used in each support airbag 1 forming the head region 8, waist and back region 9, hip region 10, leg region 11, and foot region 12 can be adjusted according to the actual usage needs of the user, and should all be considered as specific implementation methods of this embodiment.

[0046] In this embodiment, the length of the support airbags 1 corresponds to the width of the mattress body, so that the support airbags 1 are arranged side by side along the length of the mattress body to form the support surface of the mattress body. The length of the support airbags 1 is the same as the width of the mattress body, so that the support airbags 1 can be assembled by simply laying them in the front-to-back direction to form the support airbag cushion, thereby meeting the requirements of mattress use, effectively simplifying the structure, and improving assembly efficiency.

[0047] The structure and effect of the support airbag described in this embodiment are consistent with those in the second embodiment and will not be described in detail.
