Description

Technical Field

[0001] The invention relates to the field of bedding, and in particular to a supporting airbag, a supporting airbag cushion and a mattress. Background Art

[0002] The existing mattress includes a support bag cushion, which includes closely arranged support air bags, and adjacent support air bags are connected by airways so that the air pressure of each support air bag on the support bag cushion can be adjusted synchronously, thereby ensuring that the hardness of the support bag cushion is adjustable. The existing support air bag includes a bag body with a bag cavity, the bag body is cylindrical, and has a smooth outer wall. When inflated, the middle part of the outer wall of the bag body will expand radially due to the lack of a limiting structure, resulting in the bag body being unable to provide effective support force upwards due to radial expansion, thereby reducing the support performance of the support air bag and affecting the user experience. Summary of the invention

[0003] In order to address the deficiencies of the prior art, the utility model provides a support airbag, a support airbag cushion and a mattress, wherein annular reinforcing ribs are arranged on the outer wall of the airbag body, and the reinforcing ribs are utilized to limit the radial expansion of the airbag body, thereby ensuring that the airbag body has better vertical support performance and improving lying comfort.

[0004] The present invention is realized in the following manner: a support airbag, comprising a bladder body with a bladder cavity therein, the bladder body being columnar, and the outer wall of the bladder body being provided with annular reinforcing ribs arranged around the circumference thereof to limit the radial expansion of the bladder body when inflated. Annular reinforcing ribs are arranged on the outer wall of the bladder body, and the reinforcing ribs are used to limit the radial expansion of the bladder body, which not only ensures that the bladder body can be vertically extended when inflated, thereby ensuring that the bladder body has good vertical support performance and improves lying comfort, but also ensures that adjacent bladder bodies do not interfere with each other, prevents collisions, protects the bladder body, and ensures that the axis of the bladder body always maintains a vertical posture, ensuring that the bladder body has good vertical support performance.

[0005] Preferably, the reinforcing ribs are multiple and staggered and equidistantly arranged along the sac axis. The reinforcing ribs are arranged on each height section of the sac outer wall, so that each section of the sac outer wall has good anti-radial expansion performance.

[0006] Preferably, the single reinforcing rib is arranged horizontally. The reinforcing rib is arranged horizontally in a ring shape, which ensures that each section of the outer side wall of the capsule can obtain good anti-radial expansion performance and is convenient for processing.

[0007] Preferably, there are at least three reinforcing ribs, which can reduce the distance between adjacent reinforcing ribs by increasing the number of reinforcing ribs, thereby improving the radial expansion resistance of each section, and can also simplify the structure by limiting the number of reinforcing ribs, thereby facilitating processing and production.

[0008] Preferably, the cross-sectional profile of the reinforcing rib is square, and each corner of the cross-sectional profile of the reinforcing rib is provided with a rounded corner. The reinforcing rib with a square cross-sectional profile has good tensile strength, thereby improving the radial expansion resistance of the outer wall of the capsule. The cross-sectional corners of the reinforcing rib are provided with a rounded corner, which is convenient for processing and can effectively disperse the force, thereby preventing damage to adjacent reinforcing ribs due to mutual friction.

[0009] Preferably, the reinforcing rib is formed by the outer wall of the capsule body protruding outwards. The reinforcing rib and the capsule body are integrally processed and formed, which is convenient for batch processing and ensures that the reinforcing rib and the capsule body are firmly connected, effectively improving the anti-radial expansion performance of the side wall of the capsule body.

[0010] Preferably, a buffer cavity communicating with the sac cavity is provided on the top of the sac body, and the middle part of the top wall of the buffer cavity bulges upward, so that the top of the sac body can be compressed and buffered by the buffer cavity, thereby providing comfortable support for the user.

[0011] Preferably, the top of the buffer cavity is provided with an arc-shaped supporting surface, and the middle part of the buffer cavity is easily deformed due to the smaller contact area with the user, thereby matching and fitting with the user's surface to enhance the support comfort.

[0012] Preferably, the bottom periphery of the buffer cavity is radially inwardly recessed to form an annular deformation groove, which utilizes the deformation groove to form a space for the buffer cavity to swing, so that the top wall of the buffer cavity can match and fit the user's surface through swinging, and also reduces the diameter of the connection between the buffer cavity and the top edge of the outer wall of the sac body, thereby reducing the resistance of the buffer cavity when it swings and improving the swinging flexibility.

[0013] Preferably, the capsule body comprises a cover body and a bottom plate which are vertically stacked and fixed, and the bottom plate covers the bottom surface of the cover body and encloses and seals the capsule cavity. The cover body and the bottom plate are independently processed and formed as one piece, and the cover body is stacked on the bottom plate and fixed by welding, so as to ensure that the capsule cavity in the capsule body is isolated from the external space, and facilitate the adjustment of air pressure.

[0014] A support bag cushion comprises the support airbags, which are arranged in a matrix shape, and adjacent support airbags are connected by airways. The support airbags are arranged in a matrix shape to ensure that all areas of the user's surface can be effectively supported. Connecting airways are provided between adjacent support airbags, so that the air pressure in adjacent support airbags is synchronously adjusted, thereby controlling the synchronous adjustment of the softness and hardness of each support airbag, thereby improving the user experience.

[0015] A mattress comprises a support bladder, a limiting pad wrapping the support bladder, and an outer cover wrapping the support bladder and the limiting pad. The limiting block plays a role of clamping, positioning and protecting the support bladder, ensuring that the support bladder is adjusted in softness and hardness by inflation and deflation at a preset position, thereby improving the comfort of the mattress. The outer cover wraps the support bladder and the limiting pad, and plays a role of positioning and protecting the support bladder and the limiting pad.

[0016] The beneficial effects of the present invention are as follows: annular reinforcing ribs are arranged on the outer side wall of the sac body, and the reinforcing ribs are utilized to limit the radial expansion of the sac body, thereby ensuring that the sac body can stretch vertically when inflated, thereby ensuring that the sac body has good vertical support performance and improves lying comfort, and also ensuring that adjacent sac bodies do not interfere with each other, preventing conflicts and collisions, thereby protecting the sac body and ensuring that the axis of the sac body always maintains a vertical posture, ensuring that the sac body has good vertical support performance.

[0025] The essential features of the present invention are further described below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Embodiment 1:

[0027] This embodiment provides a support airbag.

[0028] like Figure 1 , 2 The support airbag shown in 3 comprises a bladder body with a bladder cavity therein, the bladder body is columnar, and the outer wall of the bladder body is provided with an annular reinforcing rib 1 arranged around the circumference thereof to limit the radial expansion of the bladder body when inflated. The annular reinforcing rib 1 is arranged on the outer wall of the bladder body, and the reinforcing rib 1 is used to limit the radial expansion of the bladder body, which not only ensures that the bladder body can be vertically extended when inflated, thereby ensuring that the bladder body has good vertical support performance and improves lying comfort, but also ensures that adjacent bladder bodies do not interfere with each other, prevents collisions, protects the bladder body, and ensures that the axis of the bladder body always maintains a vertical posture, ensuring that the bladder body has good vertical support performance.

[0029] In this embodiment, the reinforcing ribs 1 are annular and arranged around the outer wall of the bladder. Specifically, the reinforcing ribs 1 are multiple and staggered and equidistantly arranged along the axial direction of the bladder. The bladder is divided into multiple sections along its axial direction. The outer wall of each section is provided with corresponding reinforcing ribs 1. The outer wall of each section is limited by the reinforcing ribs 1 to ensure that the outer wall of the bladder will not expand radially due to the increase of air pressure, thereby ensuring that the bladder can be vertically extended when inflated, and the vertical support performance of the bladder is improved by increasing the distance between the top wall and the bottom wall of the bladder, providing effective support for the user.

[0030] In this embodiment, a single reinforcing rib 1 is arranged horizontally, and a single reinforcing rib 1 is arranged in the same horizontal plane. The reinforcing rib 1 is arranged along the center line of the outer wall of the corresponding section, and the distances between adjacent reinforcing ribs 1 are the same, ensuring that the outer wall of each section of the capsule has balanced anti-radial expansion performance.

[0031] In this embodiment, there are at least three reinforcing ribs 1. The distance between adjacent reinforcing ribs 1 is reduced by increasing the number of reinforcing ribs 1, thereby reducing the width of the outer wall of each section, ensuring that each reinforcing rib 1 can effectively limit and shape each section, thereby preventing the outer wall of the capsule from bulging outward in the area between adjacent reinforcing ribs 1, and ensuring that the capsule maintains a cylindrical contour.

[0032] In this embodiment, the cross-sectional profile of the reinforcing rib 1 is square, and fillets 2 are provided at each corner of the cross-sectional profile of the reinforcing rib 1. The reinforcing rib 1 with a square cross-sectional profile has good structural strength, and plays a good limiting role on the outer wall of the capsule. The edge of the reinforcing rib 1 is a fillet, which effectively prevents the edge of the reinforcing rib 1 from being worn and missing, thereby preventing the reinforcing rib 1 from having uneven structural strength due to partial missing, ensuring that each circumferential section of the reinforcing rib 1 has balanced tensile resistance, thereby ensuring that the capsule profile remains constant.

[0033] In this embodiment, the reinforcing rib 1 is formed by the outer wall of the capsule body bulging outward. The capsule body includes a cover body 6 and a bottom plate that are vertically stacked and fixed. The bottom plate covers the bottom surface of the cover body 6 and encloses and blocks to form the capsule cavity. The reinforcing rib 1 and the cover body 6 are integrally processed to ensure that the two are firmly connected and improve the radial deformation resistance of the cover body 6. The bottom plate is integrally processed. During installation, the cover body 6 is covered on the bottom plate and fixed by welding so that the cover body 6 and the bottom plate enclose the capsule body, which is convenient for processing and reduces the workload, and also improves the sealing reliability by reducing the welding area.

[0034] In this embodiment, a buffer cavity 3 communicating with the bladder cavity is provided at the top of the bladder body. A supporting surface 4 in the shape of an arc is provided at the top of the buffer cavity 3, and the middle part of the supporting surface 4 bulges upward. When in use, the middle part of the supporting surface 4 is deformed under pressure and the contact area with the user is increased, which not only ensures that the supporting surface 4 can match and fit the user's surface through deformation, but also can use the bladder body to implement vertical support for the user, thereby improving the support comfort.

[0035] It can be understood that the bottom periphery of the buffer cavity 3 is recessed radially inward to form an annular deformation groove 5 (such as Figure 4 and 5 As shown), by setting a deformation groove 5, a reduced diameter structure is formed at the connection between the buffer cavity 3 and the top of the capsule body. By reducing the diameter of the connection, the buffer cavity 3 is facilitated to swing and rotate, ensuring that the supporting surface 4 can fit the surface of the user, which should also be regarded as a specific implementation method of this embodiment.

[0036] Embodiment 2:

[0037] Compared with the first embodiment, this embodiment provides a support bladder.

[0038] like Figure 6 The support cushion 8 shown includes the support airbags 7, which are arranged in a matrix shape, and adjacent support airbags 7 are connected by airways. The support airbags 7 are arranged in a matrix shape, ensuring that all areas of the user's surface can obtain effective support, thereby improving support comfort.

[0039] In this embodiment, adjacent support airbags 7 are connected by airways to ensure that the air pressures in adjacent support airbags 7 can be adjusted synchronously, which not only effectively simplifies the control system and facilitates operation, but also ensures that the relative positions of adjacent support airbags 7 remain fixed.

[0040] The structure and effect of the support airbag described in this embodiment are consistent with those in the first embodiment and will not be described in detail.

[0041] Embodiment three:

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

[0043] like Figure 7 The mattress shown comprises the support bladder 8, a limiting pad 9 wrapping the support bladder 8, and an outer cover 10 wrapping the support bladder 8 and the limiting pad 9. The limiting pad 9 holds, positions and protects the support bladder 8, ensuring that the support airbags 7 on the support bladder 8 are adjusted up and down by inflation and deflation at a preset position, which ensures that the support bladder 8 can provide effective support upwards and improve the support comfort, and also effectively prevents the adjacent support bladders 8 from interfering with each other.

[0044] In this embodiment, the limiting pad 9 is provided with perforations, and the number and positions of the perforations are matched one by one with the supporting airbags 7 on the supporting bag cushion 8. During installation, the limiting pad 9 wraps the supporting bag cushion 8, and the perforations are placed on the corresponding supporting airbags 7, so that each supporting airbag 7 is limited by the inner wall of the perforation, ensuring that the supporting airbag 7 can achieve vertical expansion and contraction under the guidance of the perforations, thereby generating vertical support for the user and providing the user with a comfortable support experience.

[0045] The structure and effect of the support bag cushion described in this embodiment are consistent with those in the second embodiment and will not be described in detail.
