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 cell includes 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 cell by raising and lowering the air pressure. The existing airbags have a consistent structure in each partition, which not only results in the airbags being unable to achieve 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, the upper and lower limits of the hardness variation of the airbags 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 shortcomings of the existing technology, the utility model provides an airbag cushion and a mattress using the same, which utilizes flexible airbags and hard airbags to alternately form adjacent partitions, so that the 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] This utility model is achieved through the following method: an airbag cushion comprising multiple sections divided from front to back, with flexible and rigid airbags alternately arranged between adjacent sections. The sidewalls of the flexible and rigid airbags are configured with small and large angles of varying degrees to provide differentiated support between adjacent sections. The flexible and rigid airbags have different structures, and the adjacent sections are formed by alternating flexible and rigid airbags. This provides differentiated support between adjacent sections of the airbag cushion, effectively increasing the range of softness and hardness adjustment, thereby meeting the user's differentiated support requirements for each section and enhancing the user experience.

[0005] Preferably, the ratio of the axial expansion and contraction amplitudes of the flexible airbag and the rigid airbag is C, 1.2≤C≤2, which ensures that there is a large difference in the axial expansion and contraction amplitudes between the flexible airbag and the rigid airbag, providing the user with a larger adjustable range of softness and hardness, thereby meeting the user's differentiated softness and hardness adjustment requirements, and also ensures that both the flexible airbag and the rigid airbag can provide support to the user by limiting the ratio of the axial expansion and contraction amplitudes, ensuring that the flexible airbag can be smoothly reset, and preventing the situation where the flexible airbag cannot be reset or reset offset occurs due to excessive deformation of the flexible airbag.

[0006] Preferably, the rigid airbag includes vertically stacked and mutually connected rigid cavities, the middle portion of the outer peripheral wall of the rigid cavity bulges outward to form a large fold angle in the shape of an isosceles triangle, and the large fold angle is A, 100°<A≤140°. Increasing the angle parameter of the large fold angle effectively reduces the vertical expansion and contraction deformation amplitude of the rigid airbag, which not only improves the speed of adjusting the hardness and softness by reducing the inflation volume, but also ensures that the rigid airbag expands and contracts vertically, prevents interference between adjacent rigid airbags, and ensures that the top surface of the rigid airbag remains flat, thereby improving the aesthetics. 100°<A≤140° not only ensures that the hard cavity has a vertical deformation stroke, thereby facilitating the adjustment of the hardness and softness of the rigid airbag, but also controls the vertical deformation amplitude of the rigid airbag by limiting the vertical deformation stroke of the hard cavity, thereby ensuring that the rigid airbag can maintain a flat top surface after deflation and facilitates re-inflation to increase the hardness.

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

[0008] Preferably, there are at least four hard cavities, which are vertically stacked and interconnected, ensuring that the air pressure in each hard cavity can be adjusted synchronously, and that the vertical deformation of the hard cavity generated by inflation and deflation can be superimposed to form the vertical deformation amplitude of the hard airbag, thereby reducing the vertical deformation amplitude of the hard cavity to ensure its reciprocating deformation along a preset path.

[0009] Preferably, the flexible airbag comprises vertically stacked and interconnected flexible chambers. The central portion of the outer peripheral wall of the flexible chamber bulges outward to form a small angle in the shape of an isosceles triangle. This small angle is designated B, and ranges from 80° to 100°. Reducing the angle of the small angle effectively increases the vertical expansion and contraction range of the flexible airbag, thereby increasing the range of softness and hardness adjustment, meeting user requirements for the airbag cushion and enhancing the user experience.

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

[0011] Preferably, there are at least four flexible chambers, which are vertically stacked and interconnected, ensuring that the air pressure in each flexible chamber can be adjusted synchronously and that the vertical deformations generated by the inflation and deflation of the flexible chambers can be superimposed to form the vertical deformation amplitude of the flexible airbag. By reducing the vertical deformation amplitude of the flexible chamber, it is ensured that it can reciprocate along a preset path.

[0012] Preferably, the rigid and flexible airbags are each provided with a connecting piece at their central periphery. Adjacent rigid and flexible airbags, as well as adjacent compartments, 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 rigid and flexible airbags. This ensures that when the rigid and flexible airbags are assembled to form the airbag cushion, they are welded together at their corresponding edges. This ensures reliable connection and facilitates arbitrary welding and assembly as needed, allowing the compartmentalized layout 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 flexible airbags; alternatively, the waist area is formed by combining flexible airbags; alternatively, the leg area is formed by combining flexible airbags; alternatively, the shoulder and back area is formed by combining rigid airbags; alternatively, the hip area is formed by combining rigid airbags. Each area uses flexible or rigid airbags based on the user's usage habits and needs, ensuring that each part of the user's body can obtain the support they need, 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: the flexible airbag and the hard airbag have different structures, and the flexible airbag and the hard airbag are alternately formed into adjacent partitions, so that the 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.

[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 airbag cushion shown includes multiple zones divided from front to back, with flexible airbags 1 and rigid airbags 2 alternately positioned between adjacent zones. The sidewalls of the flexible and rigid airbags 1 and 2 are configured with small and large fold angles 4 and 3 of varying degrees to provide differentiated support between adjacent zones. The flexible and rigid airbags 1 and 2 have different structures. By alternating between the zones, the adjacent zones on the airbag cushion 13 have differentiated support, effectively expanding the range of softness and hardness adjustment, thereby meeting the user's differentiated support requirements for each zone and enhancing the user experience.

[0027] In this embodiment, the rigid airbag 2 includes vertically stacked and mutually connected rigid cavities 5 (such as Figure 2 (As shown in the figure), the central portion of the outer peripheral wall of the hard cavity 5 bulges outward to form a large isosceles triangle-shaped angle 3. This large angle 3 is A, with 100° < A ≤ 140°, to limit the vertical expansion and contraction of the rigid airbag 2 during inflation and deflation. Increasing the angle between the outer peripheral edges of adjacent hard cavities 5 effectively reduces the vertical expansion and contraction of the rigid airbag 2. This not only increases the speed of hardness adjustment by reducing the inflation volume, but also ensures that the rigid airbag 2 expands and contracts in the vertical direction, preventing interference between adjacent rigid airbags 2 and ensuring a flat top surface for improved aesthetics.

[0028] In this embodiment, the flexible airbag 1 includes flexible chambers 6 (such as Figure 3As shown, the central portion of the outer peripheral wall of the flexible cavity 6 bulges outward to form a small angle 4 in the shape of an isosceles triangle. This small angle 4 is designated B, with a range of 80°≤B≤100°. This increases the vertical expansion and contraction range of the flexible airbag 1 during inflation and deflation. The vertical profile between the outer peripheral edges of adjacent flexible cavities 6 is configured as an isosceles triangle, forming the small angle 4. This small angle 4 not only effectively guides the vertical expansion and contraction of the flexible airbag 1 but also increases the vertical expansion and contraction range of the flexible airbag 1 by reducing the included angle parameter, thereby increasing the hardness and softness adjustment range, meeting the user's requirements for the airbag cushion 13 and enhancing the user experience.

[0029] In this embodiment, the ratio of the axial expansion and contraction amplitude of the flexible airbag 1 and the rigid airbag 2 is C, 1.2≤C≤2, and the flexible airbag 1 and the rigid airbag 2 cooperate with each other to form an airbag cushion 13 comprising multiple partitions. The flexible airbag 1 and the rigid airbag 2 can be used to achieve differentiated support under the same air pressure by utilizing the structural differences between the flexible airbag 1 and the rigid airbag 2 themselves, and the support difference can be increased by filling the flexible airbag 1 and the rigid airbag 2 with different air pressures, thereby making the flexible airbag 1 and the rigid airbag 2 obtain better flexibility and hardness respectively, thereby meeting the differentiated needs of different users.

[0030] In this embodiment, the rigid airbags 2 are arranged in a matrix and assembled to form corresponding zones. Adjacent rigid airbags 2 are connected by airways, allowing the air pressure of each rigid airbag 2 within a zone to be adjusted synchronously. The flexible airbags 1 are arranged in a matrix and assembled to form corresponding zones. Adjacent flexible airbags 1 are connected by airways, allowing the air pressure of each flexible airbag 1 within a zone to be adjusted synchronously. Each zone is formed by an arrangement of flexible airbags 1 or rigid airbags 2 with the same structure, facilitating mass assembly and ensuring uniform hardness across the top surface of each zone, thereby enhancing user comfort.

[0031] In this embodiment, there are at least four hard cavities 5 and at least four soft cavities 6. A reasonable number of hard cavities 5 and soft cavities 6 is set to ensure that the hard airbag 2 and the flexible airbag 1 have a telescopic range that meets the use requirements, and also ensure that the hard airbag 2 and the flexible airbag 1 can stably telescope, prevent the hard airbag 2 and the flexible airbag 1 from axial deviation, and ensure that the top surfaces of the hard airbag 2 and the flexible airbag 1 remain flat and rise and fall in a horizontal posture.

[0032] In this embodiment, the central periphery of the rigid airbag 2 and the flexible airbag 1 is provided with a connecting piece 7, and the adjacent rigid airbags 2, the adjacent flexible airbags 1 and the adjacent partitions are all adhered by overlapping and welding the edges of the corresponding connecting pieces 7. The rigid airbags 2 or the flexible airbags 1 are formed into airbag strips by overlapping and welding the corresponding side edges of the connecting piece 7, and the adjacent airbag strips are formed into partitions by overlapping and welding the corresponding front and rear edges of the connecting piece 7. The adjacent partitions are formed into airbag cushions 13 by overlapping and welding the corresponding front and rear edges of the connecting piece 7. The rigid airbags 2 and the flexible airbags 1 produced in batches are quickly processed and assembled, which effectively reduces costs and improves production efficiency.

[0033] In this embodiment, there are five zones, including a head zone 8, a shoulder zone 9, a waist zone 10, a hip zone 11, and a leg zone 12 (as shown in FIG. Figure 4 Adjacent zones alternate between rigid airbags 2 and flexible airbags 1. The head zone 8, waist zone 10, and leg zone 12 are all formed by flexible airbags 1, while the shoulder and back zones 9 and hip zones 11 are all formed by rigid airbags 2. This provides appropriate support for each segment of the user's body, enhancing the user's sleeping experience. Furthermore, each zone can utilize either rigid airbags 2 or flexible airbags 1 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.

[0034] Example 2:

[0035] Compared with the first embodiment, this embodiment provides a mattress.

[0036] like Figure 5 The mattress shown includes a cushion body, which includes an airbag cushion 13 and a stopper 14 that clamps and encloses the airbag cushion 13. The stopper 14 clamps, positions, and protects the airbag cushion 13, ensuring that the airbag cushion 13 is adjusted in a preset position by inflation and deflation, thereby improving the comfort of the cushion body.

[0037] In this embodiment, the limit block 14 is provided with perforations, and the number and position of the perforations are matched one by one with the hard airbag 2 and the flexible airbag 1 on the airbag cushion 13. During installation, the limit block 14 wraps the airbag cushion 13, and the perforations are placed on the corresponding hard airbag 2 and flexible airbag 1, so that each hard airbag 2 and flexible airbag 1 is limited by the inner wall of the perforation, ensuring that the hard airbag 2 and the flexible airbag 1 can achieve vertical expansion and contraction under the guidance of the perforations, and then the hardness and softness can be adjusted by adjusting the air pressure to provide comfortable support for the user.

[0038] 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.
