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, each comprising airbag strips tightly arranged in a front-to-back direction. Each strip is provided with linearly arranged cell cells. Adjacent cell cells are connected by air passages, enabling synchronous regulation of the air pressure within each cell within the strip. This allows for synchronized regulation of the air pressure within adjacent airbag strips when they are interconnected. The cell cells comprise a plurality of vertically stacked, interconnected cell cavities, each of which has its own air pressure that can be synchronously regulated. The firmness of the cell cells can be adjusted by adjusting the air pressure. Due to the large range of movement of the existing cell cells, the cell cells can over-shrink after deflation, causing the top surface of the airbag cushion to collapse. This not only requires the cell cells to be filled with large amounts of high-pressure air to achieve the desired firmness, prolonging the inflation time, but also prevents them from expanding or contracting along the predetermined path due to their large expansion and contraction deformation, making them susceptible to deviation or tilting. This can lead to interference between adjacent cell cells, and the excessive collapse of the top surface of the airbag cushion can affect its aesthetics. Utility Model Content

[0003] In order to address the deficiencies of the prior art, the utility model provides an airbag cushion and a mattress using the same, which increases the angle parameter between the end edge of the outer peripheral wall of the unit cavity and the horizontal plane, effectively reducing the vertical expansion and contraction deformation amplitude of the unit bag, thereby increasing the softness and hardness adjustment speed by reducing the inflation volume, ensuring the vertical expansion and contraction of the unit bag, and ensuring that the top surface of the airbag cushion remains flat, thereby improving the aesthetics.

[0004] The present invention is achieved through the following method: an airbag cushion comprising airbag strips tightly arranged in a front-to-back direction, the airbag strips comprising a plurality of linearly arranged unit cells, the unit cells comprising vertically stacked and interconnected unit cavities, the vertical cross-sectional profile of the outer peripheral wall of the unit cavity being an isosceles triangle with a central portion bulging outward, the angle A between the end edge of the outer peripheral wall of the unit cavity and a horizontal plane being 50° < A ≤ 70°, thereby limiting the vertical expansion and contraction amplitude of the unit cells during inflation and deflation. Increasing the angle parameter between the end edge of the outer peripheral wall of the unit cavity and the horizontal plane effectively reduces the vertical expansion and contraction amplitude of the unit cells, thereby increasing the speed of hardness adjustment by reducing the inflation volume, ensuring that the unit cells expand and contract vertically, preventing interference between adjacent unit cells, and ensuring that the top surface of the airbag cushion remains flat, improving the aesthetics. The angle parameter is A, 50°<A≤70°, which not only ensures that the unit cavity has a vertical deformation stroke, thereby facilitating the adjustment of the softness and hardness of the airbag cushion, but also controls the vertical deformation amplitude of the unit bag by limiting the vertical deformation stroke of the unit cavity, thereby ensuring that the airbag cushion can maintain a flat top surface after deflation and facilitate re-inflation to increase the hardness.

[0005] Preferably, the horizontal cross-sectional profile of the cell cavity is circular, so that each circumferential segment of the cell cavity's outer wall has the same vertical cross-sectional profile. A circular cell cavity with a circular outer wall profile ensures that each segment of the cell cavity's outer wall has the same angle with the horizontal plane. This not only facilitates the synchronous change of parameter A during inflation and deflation of the cell bladder, but also ensures that the cell cavity can form vertical expansion and contraction deformation along its axis, ensuring that the top surface of the cell bladder can be raised in a horizontal position and stably support the user.

[0006] Preferably, the angle between the top edge of the outer peripheral wall of the unit cavity and the horizontal plane is A, or the angle between the bottom edge of the outer peripheral wall of the unit cavity and the horizontal plane is A. The angles between the top and bottom edges of the outer peripheral wall of the unit cavity and the horizontal plane are both A, and change synchronously with the inflation and deflation operations, ensuring that the top surface of the unit capsule rises and falls smoothly in a horizontal posture, and preventing adjacent unit capsules from interfering with each other due to tilting.

[0007] Preferably, the outer peripheral wall of the cell cavity is provided with an outwardly bulging outer corner in the middle, which opens and closes to guide the vertical expansion and contraction of the cell capsule. The outer corner can be opened and closed during inflation and deflation, thereby adjusting the vertical expansion and contraction of the cell cavity by adjusting the angle between the upper and lower portions of the outer peripheral wall, thus guiding the vertical expansion and contraction of the cell cavity.

[0008] Preferably, the ratio of the height of the unit bladder when inflated to when deflated is B, 1.15≤B≤1.2, which ensures that the hardness of the unit bladder is adjustable to meet the user's differentiated hardness requirements, and reduces the vertical expansion and contraction range of the unit bladder by reducing the parameter B, making it convenient to quickly adjust the air pressure, and ensures that the unit bladder has a larger volume after deflation by reducing the change in the lifting amplitude, effectively maintaining the preset contour.

[0009] Preferably, A=60°, which not only ensures that the unit cavity has a vertical deformation stroke, thereby facilitating adjustment of the hardness of the airbag cushion, but also controls the vertical deformation amplitude of the unit bag by limiting the vertical deformation stroke of the unit cavity, thereby ensuring that the airbag cushion can maintain a flat top surface after deflation and facilitate re-inflation to increase hardness.

[0010] Preferably, the unit capsule includes at least four vertically stacked unit cavities, each having the same contour. By providing multiple unit cavities, the unit capsule height meets preset requirements. This not only ensures that the vertical deformation amplitudes of the unit cavities can be superimposed, so that the vertical deformation amplitude of the unit capsule meets the usage requirements, but also reduces the vertical deformation amplitude requirements of each unit cavity, thereby effectively preventing the unit cavities from deforming horizontally.

[0011] Preferably, the middle portions of adjacent unit cells are connected by air passages, so that the air pressure in each unit cell on the air cell strip can be adjusted synchronously. The air passages are used to connect adjacent unit cells, so that the air pressure in adjacent unit cells can be adjusted synchronously, ensuring that the softness and hardness of the unit cells can be adjusted synchronously.

[0012] Preferably, the wall thickness of the unit bag is C, 0.8mm≤C≤1.2mm, which ensures that the unit bag has good anti-deformation performance and prevents the unit bag from excessively collapsing after deflation, ensures that the unit bag can reserve more air in the deflated state, effectively reducing the amount of air required for inflation, and reduces the amount of raw materials by limiting the thickness, thereby reducing the cost of raw materials. By improving the softness of the unit bag wall, it ensures that the circumferential areas of the outer wall of the unit bag can deform synchronously, thereby ensuring that the top surface of the unit bag can rise and fall smoothly in a horizontal posture.

[0013] 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.

[0014] The beneficial effects of the present invention are as follows: the angle parameter between the end edge of the outer peripheral wall of the unit cavity and the horizontal plane is increased, which effectively reduces the vertical expansion and contraction deformation amplitude of the unit bag, improves the hardness adjustment speed by reducing the inflation volume, ensures the vertical expansion and contraction of the unit bag, prevents interference between adjacent unit bags, and ensures that the top surface of the airbag cushion remains flat, thereby improving the aesthetics.

[0019] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0020] Example 1:

[0021] This embodiment provides an airbag cushion.

[0022] like Figure 1 and 2The illustrated airbag cushion comprises a tightly packed front-to-back airbag strip 1, comprising a plurality of linearly arranged unit cells 2. Each unit cell 2 comprises vertically stacked and interconnected unit cavities 3. The vertical cross-sectional profile of the outer peripheral wall of each unit cavity 3 is an isosceles triangle with a centrally bulging portion. The angle A between the outer peripheral edge of each unit cavity 3 and the horizontal plane is 50° < A ≤ 70°, effectively limiting the vertical expansion and contraction of the unit cells 2 during inflation and deflation. Increasing the angle between the outer peripheral edge of each unit cavity 3 and the horizontal plane effectively reduces the vertical expansion and contraction of the unit cells 2. This not only increases the speed of hardness adjustment by reducing the amount of inflation, but also ensures vertical expansion and contraction of the unit cells 2, preventing interference between adjacent unit cells 2. Furthermore, it ensures a flat top surface for the airbag cushion 5, enhancing its aesthetics.

[0023] In this embodiment, A = 60°. This ensures that the unit cavity 3 has a vertical deformation range, thereby facilitating adjustment of the hardness of the airbag cushion 5. By limiting the vertical deformation range of the unit cavity 3, the vertical deformation amplitude of the unit bladder 2 is controlled, thereby ensuring that the airbag cushion 5 maintains a flat top surface after deflation and facilitating reinflation to increase hardness. Parameter A can also be set to 51°, 55°, 65°, 70°, and so on. As long as the requirement of 50° < A ≤ 70° is met, it should be considered a specific implementation of this embodiment.

[0024] In this embodiment, the vertical cross-sectional profile of the outer peripheral wall of the cell cavity 3 is an isosceles triangle with a central bulge. The upper and lower portions of the outer peripheral wall of the cell cavity 3 have the same width and form two waists of the triangular profile. The central portion of the outer peripheral wall of the cell cavity 3 bulges outward to form an outer corner 4 located at the top of the isosceles triangle. The corresponding end edges of the outer peripheral walls of adjacent cell cavities 3 are connected to form an inwardly recessed inner corner. The provision of waists of equal width ensures that the inner corner and the outer corner 4 can open and close synchronously. During inflation and deflation of the cell capsule 2, the outer corner 4 and the inner corner open and close synchronously, guiding the vertical expansion and contraction of the cell capsule 2. This causes the angle between the top and bottom of the outer peripheral wall of the same cell cavity 3 and between the adjacent top and bottom of the outer peripheral walls of adjacent cell cavities 3 to change, thereby changing the height of the cell capsule 2. Specifically, when inflated, the cell capsule 2 increases in height and stiffness; when deflated, the cell capsule 2 decreases in height and stiffness. The hardness is adjusted by inflating and deflating the unit capsule 2 .

[0025] In this embodiment, the ratio of the height of the unit capsule 2 when inflated to when deflated is B, 1.15≤B≤1.2. By setting a reasonable parameter A, the unit capsule 2 has a parameter B that meets the usage requirements when switching between inflation and deflation. This ensures that the hardness of the unit capsule 2 is adjustable to meet the user's differentiated hardness requirements, facilitates and quickly adjusts the air pressure, and ensures that the unit capsule 2 has a larger volume after deflation by reducing the change in the lifting amplitude, effectively maintaining the preset contour.

[0026] In this embodiment, the horizontal cross-sectional profile of the unit cavity 3 is circular, so that each circumferential section of the outer peripheral wall of the unit cavity 3 has the same vertical cross-sectional profile. The radial cross-sectional profiles of the unit cavity 3 are all the same. During inflation and deflation operations, each circumferential section of the unit cavity 3 can rise and fall synchronously, ensuring that the unit capsule 2 can rise and fall vertically while maintaining a horizontal top surface.

[0027] In this embodiment, the angle between the top edge of the outer peripheral wall of the unit cavity 3 and the horizontal plane is A, and the angle between the bottom edge of the outer peripheral wall of the unit cavity 3 and the horizontal plane is A, so that the contours of the vertical radial surfaces of the unit cavity 3 are the same, guiding the unit capsule 2 to telescope along the preset path.

[0028] In this embodiment, the unit bladder 2 comprises at least four vertically stacked unit cavities 3, each having the same contour. The vertical stacking of the unit cavities 3 allows the vertical deformation amplitudes of each unit cavity 3 to be superimposed, ensuring that the expansion and contraction amplitude of the unit bladder 2 meets the required operating conditions. Preferably, the unit bladder 2 comprises eight vertically stacked unit cavities 3, with the midsections of adjacent unit bladders 2 fixedly connected to each other, ensuring that adjacent unit bladders 2 can be connected to form the airbag strip 1.

[0029] In this embodiment, adjacent cells 2 are connected by air passages in the middle, allowing for simultaneous adjustment of the air pressure within each cell 2 of the airbag strip 1. Cells 2 at the ends of the airbag strip 1 extend outward to form air ports that communicate with an external air source, allowing for simultaneous adjustment of the air pressure within each cell 2 of the airbag strip 1.

[0030] In this embodiment, the wall thickness of the cell bladder 2 is C, 0.8mm≤C≤1.2mm, and preferably, C=1mm. This ensures that the cell bladder 2 has good deformation resistance, preventing excessive collapse after deflation. It also ensures that the cell bladder 2 retains a large amount of air in the deflated state, effectively reducing the amount of air required for inflation. By limiting the thickness, it also reduces raw material usage, thereby lowering raw material costs. By increasing the flexibility of the cell bladder 2 wall, it ensures that all circumferential regions of the outer wall of the cell bladder 2 can deform synchronously, thereby ensuring that the top surface of the cell bladder 2 can be raised and lowered smoothly in a horizontal position. Alternatively, parameter C can be 0.8mm, 0.9mm, 1.1mm, 1.2mm, etc. As long as the requirement of 0.8mm≤C≤1.2mm is met, it should be considered a specific embodiment of this embodiment.

[0031] In this embodiment, the leading and trailing edges of adjacent airbag strips 1 are both provided with connecting edges. The adjacent airbag strips 1 are arranged side by side and are overlapped and welded via the connecting edges, so that the airbag strips 1 are assembled to form an airbag cushion 5 .

[0032] Example 2:

[0033] Compared with the first embodiment, this embodiment provides a mattress.

[0034] like Figure 3 As shown, the mattress includes a cushion body, which includes an airbag cushion 5 and a stopper 6 that clamps and wraps the airbag cushion 5. The stopper 6 holds, positions, and protects the airbag cushion 5, ensuring that the airbag cushion 5 is adjusted in a preset position by inflation and deflation, thereby improving the comfort of the cushion body.

[0035] In this embodiment, the limit block 6 is provided with perforations, and the number and position of the perforations are matched one by one with the unit capsules 2 on the airbag cushion 5. During installation, the limit block 6 wraps the airbag cushion 5, and the perforations are placed on the corresponding unit capsules 2, so that each unit capsule 2 is limited by the inner wall of the perforation, ensuring that the unit capsule 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.

[0036] 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.
