Description

Technical Field

[0001] The utility model relates to the field of bedding, in particular to an airbag cushion and a mattress using the airbag cushion. Background Art

[0002] Existing mattresses include airbag cushions, which include airbag strips tightly arranged in the front-to-back direction. The airbag strips are provided with unit cells arranged in a straight line. Adjacent unit cells are connected by air passages so that the air pressure of each unit cell on the airbag strip can be adjusted synchronously, thereby enabling adjacent airbag strips to achieve synchronous air pressure adjustment when they are interconnected. The unit cells include a number of vertically stacked and interconnected unit cavities. The air pressure in each unit cavity can be adjusted synchronously, thereby adjusting the hardness of the unit cells by raising and lowering the air pressure. The structure and wall thickness of the unit cells in each partition of the existing airbag are consistent, which not only results in the airbag being unable to obtain differentiated hardness under the same inflation volume, but also requires applying different air pressures to each partition to achieve differentiated support. In addition, due to the consistent structure and wall thickness, the upper and lower limits of the hardness variation of the airbag are the same, which cannot meet the user's differentiated usage requirements for each partition, affecting the user experience. Utility Model Content

[0003] In order to address the deficiencies of the prior art, the present invention provides an airbag cushion and a mattress using the same, which utilizes thin-walled airbags and thick-walled airbags to alternately form adjacent partitions, so that adjacent partitions on the airbag cushion have differentiated support, effectively increasing the softness and hardness adjustment range, thereby meeting the user's differentiated support requirements for each partition and improving the user experience.

[0004] The present invention is achieved through the following method: an airbag cushion comprising a plurality of zones divided from front to back, with thin-walled airbags and thick-walled airbags alternately arranged between adjacent zones, the thin-walled airbags and thick-walled airbags having differentiated wall thicknesses to provide differentiated support between adjacent zones. The thin-walled airbags and thick-walled airbags achieve differentiated structural strengths by having different wall thicknesses, thereby achieving differentiated deformation resistance. This allows the thin-walled airbags and thick-walled airbags to have differentiated softness and hardness when subjected to the same air pressure. The alternating thin-walled airbags and thick-walled airbags form adjacent zones, resulting in differentiated support for adjacent zones on the airbag cushion. The differentiated air pressure and differentiated wall thicknesses achieve a combined softness and hardness adjustment effect, effectively increasing the upper and lower limits of the softness and hardness adjustment range, thereby meeting the user's differentiated support requirements for each zone and enhancing the user experience.

[0005] Preferably, the wall thickness of the thin-walled airbag is A, 0.8mm≤A≤1.2mm. The structural strength is reduced by reducing the wall thickness, and the softness is improved by reducing the deformation resistance, thereby providing soft and comfortable support for the user.

[0006] Preferably, the walls of the thin-walled airbag have the same thickness, ensuring that each wall has balanced anti-deformation performance, preventing the thin-walled airbag from deforming unevenly due to greater local structural strength, and ensuring that the thin-walled airbag can expand and contract along a preset direction.

[0007] Preferably, the thin-walled airbags are arranged in a matrix and assembled to form corresponding zones, with adjacent thin-walled airbags connected by airways, so that the air pressure of each thin-walled airbag within a zone can be adjusted synchronously. The thin-walled airbags are arranged in a matrix and assembled to form corresponding zones, with adjacent thin-walled airbags connected by airways, so that the air pressure of each thin-walled airbag within the same zone can be adjusted synchronously, thereby allowing the softness and hardness of each zone within the zone to be adjusted synchronously.

[0008] Preferably, the wall thickness of the thick-walled airbag is B, 1.8mm≤B≤2.2mm, and the structural strength is improved by increasing the wall thickness, and the hardness is improved by improving the anti-deformation performance, thereby providing effective support for the user.

[0009] Preferably, the thickness of each wall of the thick-walled airbag is the same, ensuring that each wall has balanced anti-deformation performance, preventing the thick-walled airbag from deforming unevenly due to low local structural strength, and ensuring that the thick-walled airbag can expand and contract along a preset direction.

[0010] Preferably, the thick-walled airbags are arranged in a matrix and assembled to form corresponding zones, with adjacent thick-walled airbags connected by airways, so that the air pressure of each thick-walled airbag within a zone can be adjusted synchronously. The thick-walled airbags are arranged in a matrix and assembled to form corresponding zones, with adjacent thick-walled airbags connected by airways, so that the air pressure of each thick-walled airbag within the same zone can be adjusted synchronously, thereby allowing the softness and hardness of each zone within the zone to be adjusted synchronously.

[0011] Preferably, both the thin-walled and thick-walled airbags are formed by vertically stacking interconnected unit cavities. The central portion of the outer peripheral wall of each unit cavity bulges outward, forming an isosceles triangle-shaped angle. The angle is C, with a range of 80°≤C≤100°. Setting appropriate angle parameters ensures that the thin-walled and thick-walled airbags have vertical deformation range, facilitating adjustment of hardness and softness through inflation and deflation. Furthermore, the thin-walled and thick-walled airbags can utilize their inherent structure to exhibit differentiated hardness and softness, meeting the user's differentiated needs for each compartment.

[0012] Preferably, the thin-walled and thick-walled airbags are each provided with a connecting piece at their central periphery. Adjacent thin-walled airbags, adjacent thick-walled airbags, and adjacent partitions are bonded together by overlapping and welding the edges of the corresponding connecting pieces. The connecting piece is annular and positioned at the central periphery of the thin-walled and thick-walled airbags. This ensures that the thin-walled and thick-walled airbags are welded together at their corresponding edges when assembled to form the airbag cushion. This ensures reliable connection and facilitates arbitrary welding and assembly as needed, allowing the partitioned arrangement of the airbag cushion to meet the diverse user needs.

[0013] Preferably, the number of zones is five, including a head zone, a shoulder zone, a waist zone, a hip zone, and a leg zone, which are formed in sequence from front to back. By providing five zones, each torso of the user is supported separately, thereby ensuring that each torso of the user can obtain comfortable support.

[0014] Preferably, the head area is formed by combining thin-walled airbags; alternatively, the waist area is formed by combining thin-walled airbags; alternatively, the leg area is formed by combining thin-walled airbags; alternatively, the shoulder and back area is formed by combining thick-walled airbags; alternatively, the hip area is formed by combining thick-walled airbags. Thin-walled and thick-walled airbags are selected for each area based on the user's usage habits and needs, ensuring that each area of ​​the user's body can obtain the support they require, effectively improving the user experience.

[0015] A mattress using the airbag cushion comprises a cushion body, the cushion body including the airbag cushion and a retaining block that clamps and encloses the airbag cushion. The retaining block holds, positions, and protects the airbag cushion, ensuring that the airbag cushion is adjusted in a preset position by inflation and deflation, thereby improving the comfort of the cushion body.

[0016] The beneficial effects of the present invention are as follows: thin-walled airbags and thick-walled airbags obtain differentiated structural strength by setting different wall thicknesses, and thus obtain differentiated anti-deformation performance, so that thin-walled airbags and thick-walled airbags produce differentiated softness and hardness at the same air pressure. Adjacent partitions are formed alternately by thin-walled airbags and thick-walled airbags, so that adjacent partitions on the airbag cushion have differentiated support. The softness and hardness adjustment effects are superimposed by differentiated air pressure and differentiated wall thickness, which effectively increases the upper and lower limits of the softness and hardness adjustment, thereby meeting the user's differentiated support requirements for each partition and improving the user experience.

[0023] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0024] Example 1:

[0025] This embodiment provides an airbag cushion.

[0026] like Figure 1 The illustrated airbag cushion comprises multiple zones, divided from front to back. Adjacent zones are alternately provided with thin-walled airbags 1 and thick-walled airbags 2. These thin-walled airbags 1 and thick-walled airbags 2 have differentiated wall thicknesses, resulting in differentiated support between adjacent zones. The thin-walled airbags 1 and thick-walled airbags 2 achieve differentiated structural strength and, consequently, differentiated deformation resistance by providing different wall thicknesses. This results in the thin-walled airbags 1 and thick-walled airbags 2 exhibiting differentiated hardness and softness under the same air pressure. The alternating formation of adjacent zones by thin-walled airbags 1 and thick-walled airbags 2 provides differentiated support between adjacent zones on the airbag cushion 10. The combined effects of different air pressures and wall thicknesses achieve a combined hardness adjustment, effectively expanding the upper and lower limits of the hardness adjustment range, thereby meeting the user's differentiated support requirements for each zone and enhancing the user experience.

[0027] In this embodiment, the thin-walled airbag 1 and thick-walled airbag 2 have different wall thicknesses. Specifically, the thin-walled airbag 1 has a thinner wall thickness, resulting in a weaker structural strength and being easily deformed by external forces. The rear-walled airbag 2 has a thicker wall thickness, resulting in a stronger structural strength and less prone to deformation by external forces, while also exhibiting better restorability. Under the same air pressure, the thin-walled airbag 1 and the thick-walled airbag 2 can exhibit different degrees of softness and hardness, thereby providing comfortable support for the user. Furthermore, by setting different air pressures for the thin-walled airbag 1 and the thick-walled airbag 2, a correlated effect on their hardness can be generated. By combining the correlated effects of wall thickness and air pressure, the upper and lower limits of the hardness between the thin-walled airbag 1 and the thick-walled airbag 2 can be increased. For example, increasing the air pressure in the rear-walled airbag 2 results in a higher upper limit of hardness, making it harder, while decreasing the air pressure in the thin-walled airbag 1 results in a lower lower limit of hardness, making it softer.

[0028] In this embodiment, the wall thickness of the thin-walled airbag 1 is A (e.g. Figure 2 As shown, 0.8mm≤A≤1.2mm ensures that the wall thickness meets the requirements for damage resistance and prevents leakage. Furthermore, reducing the wall thickness reduces deformation resistance, making it more flexible. Parameter A can be set as needed, and can be 0.8mm, 1mm, 1.2mm, etc., all of which should be considered specific implementations of this embodiment.

[0029] In this embodiment, the wall thickness of the thick-walled airbag 2 is B (eg Figure 3 Parameter B can be set as needed, and can be 1.8mm, 2mm, 2.2mm, etc., all of which should be considered specific implementations of this embodiment.

[0030] In this embodiment, the thin-walled airbag 1 has the same thickness on all walls, while the thick-walled airbag 2 has the same thickness on all walls. Both thin-walled airbag 1 and thick-walled airbag 2 are formed from materials of predetermined thicknesses, ensuring balanced deformation resistance on all walls. This prevents uneven deformation of the thin-walled airbag 1 and thick-walled airbag 2 due to local structural strength differences, allowing them to expand and contract along predetermined directions. The thin-walled airbag 1 and thick-walled airbag 2 can be manufactured by stacking and welding sheets, integral injection molding, or integral vacuum molding, all of which are considered specific implementations of this embodiment.

[0031] In this embodiment, the partitions are formed by combining thin-walled airbags 1 or thick-walled airbags 2. The thin-walled airbags 1 or thick-walled airbags 2 are arranged in a matrix and combined to form corresponding partitions, so that each partition can obtain differentiated support.

[0032] In this embodiment, the thin-walled airbags 1 or the thick-walled airbags 2 in the same partition are connected through air passages, so that the air pressure in the partition can be adjusted synchronously, thereby ensuring that each area of ​​the partition has a balanced hardness.

[0033] In this embodiment, both the thin-walled airbag 1 and the thick-walled airbag 2 are formed by vertically stacking interconnected unit cavities. The central portion of the outer peripheral wall of each unit cavity bulges outward to form an isosceles triangle-shaped angle 3. The angle of angle 3 is C, with a range of 80°≤C≤100°. The value of angle 3 is adjusted according to changes in air pressure. Combined with the different wall thicknesses of the thin-walled airbag 1 and the thick-walled airbag 2, the thin-walled airbag 1 and the thick-walled airbag 2 exhibit different hardness adjustment ranges to meet the different support requirements of different body sections of the user.

[0034] In this embodiment, there are at least four unit cavities. A reasonable number of unit cavities is set to ensure that the thin-walled airbag 1 and the thick-walled airbag 2 have a telescopic range that meets the use requirements, and also ensure that the thin-walled airbag 1 and the thick-walled airbag 2 can stably telescope, prevent the thin-walled airbag 1 and the thick-walled airbag 2 from axial deviation, and ensure that the top surfaces of the thin-walled airbag 1 and the thick-walled airbag 2 remain flat and rise and fall in a horizontal posture.

[0035] In this embodiment, the thin-walled airbags 1 and thick-walled airbags 2 are both provided with connecting sheets 4 along their central peripheries. Adjacent thin-walled airbags 1, adjacent thick-walled airbags 2, and adjacent partitions are all bonded together by overlapping and welding the edges of the corresponding connecting sheets 4. The thin-walled airbags 1 or thick-walled airbags 2 are formed into airbag strips by overlapping and welding the corresponding side edges of the connecting sheets 4. Adjacent airbag strips are formed into partitions by overlapping and welding the corresponding front and rear edges of the connecting sheets 4. Adjacent partitions are formed into airbag cushions 10 by overlapping and welding the corresponding front and rear edges of the connecting sheets 4. The mass production of thin-walled airbags 1 and thick-walled airbags 2 allows for rapid processing and assembly, effectively reducing costs and improving production efficiency.

[0036] In this embodiment, there are five zones, including a head zone 5, a shoulder zone 6, a waist zone 7, a hip zone 8, and a leg zone 9 (as shown in FIG. Figure 4Adjacent zones alternate between thin-walled airbags 1 and thick-walled airbags 2. The head zone 5, waist zone 7, and leg zone 9 are all formed by thin-walled airbags 1, facilitating conformation to the user's corresponding torso segments. The shoulder and back zones 6 and hip zones 8 are both formed by thick-walled airbags 2, providing effective support for the user's corresponding torso segments and enhancing the user's sleeping experience. Furthermore, each zone can utilize thin-walled airbags 1 or thick-walled airbags 2 as needed, and differential air pressure can be adjusted to increase or decrease support to meet user needs. This should also be considered a specific implementation of this embodiment.

[0037] Example 2:

[0038] Compared with the first embodiment, this embodiment provides a mattress.

[0039] like Figure 5 The mattress shown includes a cushion body, which includes an airbag cushion 10 and a stopper 11 that clamps and encloses the airbag cushion 10. The stopper 11 clamps, positions, and protects the airbag cushion 10, ensuring that the airbag cushion 10 is adjusted in a preset position by inflation and deflation, thereby improving the comfort of the cushion body.

[0040] In this embodiment, the limit block 11 is provided with perforations, and the number and position of the perforations are matched one by one with the thin-walled airbag 1 and the thick-walled airbag 2 on the airbag cushion 10. During installation, the limit block 11 wraps the airbag cushion 10, and the perforations are placed on the corresponding thin-walled airbag 1 and thick-walled airbag 2, so that each thin-walled airbag 1 and thick-walled airbag 2 is limited by the inner wall of the perforation, ensuring that the thin-walled airbag 1 and the thick-walled airbag 2 can achieve vertical expansion and contraction under the guidance of the perforations, and then the hardness can be adjusted by adjusting the air pressure to provide comfortable support for the user.

[0041] The other structures and effects of the airbag cushion described in this embodiment are consistent with those in the first embodiment and will not be described in detail.
