Description

Technical Field

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

[0002] The existing mattress includes an airbag pad. The airbag pad includes airbag strips arranged closely in the front-back direction. The airbag strips are provided with unit airbags arranged in a straight line. The adjacent unit airbags are connected through an air passage so that the air pressures of the unit airbags on the airbag strips can be synchronously adjusted, and further the air pressures of the adjacent airbag strips can be synchronously adjusted when they are interconnected. The unit airbag includes a plurality of unit cavities stacked vertically and communicating with each other, and the air pressures in the unit cavities can be synchronously adjusted, and further the softness and hardness of the unit airbag can be adjusted by raising and lowering the air pressure. The structures of the existing airbags in each partition are the same, which not only causes the airbags to not obtain different softness and hardness under the same inflation volume, and different air pressures need to be applied to each partition to achieve different supporting properties, but also causes the upper and lower limit ranges of the softness and hardness change of the airbags to be the same due to the same structure, and the different use requirements of the user for each partition cannot be met, affecting the use experience. Summary of the Utility Model

[0003] In order to solve the deficiencies of the prior art, the utility model provides an airbag pad and a mattress using the same. Flexible airbags and rigid airbags are alternately formed in adjacent partitions. The flexible airbags are formed by stacking flexible airbag bodies, and the rigid airbags are formed by stacking rigid airbag bodies and flexible airbag bodies, so that the adjacent partitions on the airbag pad have different supporting properties, effectively increasing the softness and hardness adjustment range, and further meeting the different supporting property requirements of the user for each partition and improving the use experience.

[0004] The utility model is realized in the following way: An airbag pad includes a plurality of partitions divided from front to back. Flexible airbags and rigid airbags are respectively arranged between adjacent partitions. The flexible airbag includes a plurality of flexible airbag bodies stacked vertically. The rigid airbag includes a plurality of rigid airbag bodies stacked vertically and a flexible airbag body stacked above the rigid airbag body, so as to obtain different supporting properties between adjacent partitions. Flexible airbags and rigid airbags are alternately formed in adjacent partitions. The flexible airbags are formed by stacking flexible airbag bodies, and the rigid airbags are formed by stacking rigid airbag bodies and flexible airbag bodies, so that the adjacent partitions on the airbag pad have different supporting properties, effectively increasing the softness and hardness adjustment range, and further meeting the different supporting property requirements of the user for each partition and improving the use experience. There is a flexible airbag body above the rigid airbag body in the rigid airbag, and the flexible airbag body is used to play a buffering role, ensuring that the flexible airbag body can match and fit with the user's surface through its own deformation, and further improving the lying comfort.

[0005] Preferably, the flexible bladder is deformed under pressure and fits the surface of the supported object. The flexible bladder has good deformation performance, which facilitates fitting the user's surface through deformation when under pressure, thereby enhancing the user experience.

[0006] Preferably, both the flexible airbag and the rigid airbag are integrally processed and formed. This not only facilitates mass production, reduces production time, and improves production efficiency, but also enables splicing and assembly according to usage requirements to meet the diverse usage needs of users, while ensuring the sealing reliability of the walls of the flexible airbag and the rigid airbag.

[0007] Preferably, the partition is divided into five parts, including a head area, a shoulder and back area, a waist area, a hip area, and a leg area, which are sequentially formed from front to back. By setting five partitions to support each body segment of the user respectively, it is ensured that each body segment of the user can obtain comfortable support.

[0008] Preferably, the head area is formed by splicing flexible airbags; or, the waist area is formed by splicing flexible airbags; or, the leg area is formed by splicing flexible airbags; or, the shoulder and back area is formed by splicing rigid airbags; or, the hip area is formed by splicing rigid airbags. Each partition selects flexible airbags or rigid airbags according to the usage habits and requirements of each body segment of the user, so that each body segment of the user can obtain the support that meets the usage requirements, effectively enhancing the user experience.

[0009] Preferably, the flexible bladder and the rigid bladder in the rigid airbag are connected to each other, so that the air pressure in the flexible bladder and the rigid bladder is adjusted synchronously. This not only ensures that the air pressure in the flexible bladder and the rigid bladder can be adjusted synchronously, but also ensures the reliable connection at the junction between the flexible bladder and the rigid bladder, and between the rigid bladders, thereby guaranteeing the sealing reliability.

[0010] Preferably, the flexible bladders in the flexible airbag are connected to each other, so that the air pressure in the flexible airbag is adjusted synchronously. This not only ensures that the air pressure in each flexible airbag can be adjusted synchronously, but also ensures the reliable connection at the junction between the flexible bladders, thereby guaranteeing the sealing reliability.

[0011] Preferably, the rigid airbag includes at least two rigid bladders and at least one flexible bladder, and the flexible airbag includes at least two flexible bladders. The rigid airbag and the flexible airbag are set at the same height and spliced to form a partition with a top surface of the same height. The flexible bladder is softer than the rigid bladder. By setting different numbers of flexible bladders, the overall softness and hardness adjustment range of the rigid airbag and the flexible airbag can be improved, which not only meets the usage needs of users, but also uses the flexible bladder to enhance the buffering effect and ensure that the top surface of the rigid bladder can fit the user's surface through deformation.

[0012] Preferably, a large fold angle in the shape of an isosceles triangle is formed by the outward bulge in the middle of the peripheral wall of the rigid capsule body. The large fold angle is A, and 100° < A ≤ 140°, so as to limit the vertical deformation range of the rigid capsule body. Increasing the included angle parameter of the large fold angle effectively reduces the vertical telescopic deformation range of the rigid airbag, not only improves the softness and hardness adjustment speed 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, thus improving the aesthetics.

[0013] Preferably, a small fold angle in the shape of an isosceles triangle is formed by the outward bulge in the middle of the peripheral wall of the flexible capsule body. The small fold angle is B, and 80° ≤ B ≤ 100°, so as to increase the vertical deformation range of the flexible capsule body. Reducing the included angle parameter of the small fold angle effectively increases the vertical telescopic deformation range of the flexible airbag, and further increases the softness and hardness adjustment range, meeting the usage requirements of users for the airbag pad and improving the usage experience.

[0014] Preferably, the rigid airbags are arranged in a matrix and joined together to form corresponding partitions. Adjacent rigid airbags are connected by air channels, and the air pressures of the rigid airbags in the same partition can be adjusted synchronously. The rigid airbags are arranged in a matrix and joined together to form partitions, and adjacent rigid airbags are connected by air channels, so that the air pressures of the rigid airbags in the same partition can be adjusted synchronously, and thus the softness and hardness of each area in the partition can be adjusted synchronously.

[0015] Preferably, the flexible airbags are arranged in a matrix and joined together to form corresponding partitions. Adjacent flexible airbags are connected by air channels, and the air pressures of the flexible airbags in the same partition can be adjusted synchronously. The flexible airbags are arranged in a matrix and joined together to form partitions, and adjacent flexible airbags are connected by air channels, so that the air pressures of the flexible airbags in the same partition can be adjusted synchronously, and thus the softness and hardness of each area in the partition can be adjusted synchronously.

[0016] Preferably, the rigid airbag includes a flexible capsule body provided at its bottom end, so that the rigid airbag is vertically symmetrically arranged. The rigid airbag is split into two vertically symmetric unit bodies. The unit body includes a rigid capsule body and a flexible capsule body provided above the rigid capsule body. The rigid airbag is assembled by batch-producing the unit bodies, effectively improving the assembly efficiency, reducing the production cost, and ensuring that the support characteristics of the rigid airbag meet the usage requirements.

[0017] A mattress using the airbag pad includes a pad body. The pad body includes an airbag pad and a limiting block that clamps and wraps the airbag pad. The limiting block plays a role in clamping, positioning, and protecting the airbag pad, ensuring that the airbag pad is adjusted in softness and hardness by inflating and deflating at a preset position, and thus improving the usage comfort of the pad body.

[0018] Advantages of the present utility model: Flexible airbags and rigid airbags alternately form adjacent partitions. The flexible airbags are formed by stacking flexible bags, and the rigid airbags are formed by stacking rigid bags and flexible bags, so that the adjacent partitions on the airbag pad have different support properties, effectively increasing the range of softness and hardness adjustment, thereby meeting the different support property requirements of users for each partition and improving the use experience.

[0025] The following further illustrates the substantial features of the present utility model in conjunction with the drawings in the specification and the detailed embodiments.

[0026] Embodiment 1:

[0027] This embodiment provides an airbag pad.

[0028] As Figure 1An airbag cushion as shown includes multiple partitions divided from front to back. A flexible airbag 1 and a rigid airbag 2 are respectively arranged between adjacent partitions. The flexible airbag 1 includes multiple vertically stacked flexible bodies 3, and the rigid airbag 2 includes multiple vertically stacked rigid bodies 4 and a flexible body 3 stacked above the rigid body 4, so as to obtain differential support between adjacent partitions. The flexible airbag 1 and the rigid airbag 2 alternately form adjacent partitions. The flexible airbag 1 is formed by stacking the flexible bodies 3, and the rigid airbag 2 is formed by stacking the rigid bodies 4 and the flexible body 3, so that adjacent partitions on the airbag cushion 5 have differential support, effectively increasing the range of softness and hardness adjustment, thereby meeting the differential support requirements of users for each partition and improving the use experience. A flexible body 3 is arranged above the rigid body 4 in the rigid airbag 2, and the flexible body 3 is used to play a buffering role, ensuring that the flexible body 3 can match and fit with the surface of the user through its own deformation, thereby improving the lying comfort.

[0029] In this embodiment, the flexible airbag 1 includes multiple vertically stacked flexible bodies 3, and the rigid airbag 2 includes multiple vertically stacked rigid bodies 4 and a flexible body 3 stacked above the rigid body 4. The flexible airbag 1 and the rigid airbag 2 obtain differential support by setting different matching numbers of the flexible bodies 3 and the rigid bodies 4, thereby providing comfortable support for the user.

[0030] In this embodiment, the tops of both the flexible airbag 1 and the rigid airbag 2 are flexible bodies 3. The flexible body 3 is deformed under pressure and matches and fits with the surface of the supporting object. The easy deformation performance of the flexible body 3 is used to fit with the surface of the user, thereby improving the support stability and comfort by increasing the contact area and enhancing the use experience.

[0031] In this embodiment, the flexible body 3 and the rigid body 4 in the rigid airbag 2 are communicated with each other so that the air pressures in the flexible body 3 and the rigid body 4 are adjusted synchronously, and the flexible bodies 3 in the flexible airbag 1 are communicated with each other so that the air pressure in the flexible body 3 is adjusted synchronously. Both the flexible airbag 1 and the rigid airbag 2 are integrally processed and formed, which is not only convenient for batch processing and production, reduces the production time, and improves the production efficiency, but also convenient for splicing and assembling according to the use requirements to meet the differential use requirements of users, and also ensures the sealing reliability of the walls of the flexible airbag 1 and the rigid airbag 2. The flexible airbag 1 and the rigid airbag 2 are preferably processed and formed by integral injection molding or integral thermoforming, and both should be regarded as the specific implementation manners of this embodiment.

[0032] In this embodiment, a large fold angle 6 in the shape of an isosceles triangle is formed by the outward bulge in the middle of the outer peripheral wall of the rigid bladder 4. The large fold angle 6 is A, where 100° < A ≤ 140°, to limit the vertical deformation amplitude of the rigid bladder 4. By increasing the included angle parameter between the end edges of the outer peripheral walls of adjacent rigid bladders 4, the vertical telescopic deformation amplitude of the rigid airbag 2 is effectively reduced. This not only improves the softness and hardness adjustment speed by reducing the inflation volume but also ensures that the rigid airbag 2 expands and contracts vertically, preventing interference between adjacent rigid airbags 2, and ensuring that the top surface of the partition remains flat, thus enhancing the aesthetics.

[0033] In this embodiment, a small fold angle 8 in the shape of an isosceles triangle is formed by the outward bulge in the middle of the outer peripheral wall of the flexible bladder 3. The small fold angle 8 is B, where 80° ≤ B ≤ 100°, to increase the vertical deformation amplitude of the flexible bladder 3. By setting the vertical profile between the end edges of the outer peripheral walls of adjacent flexible bladders 3 to be in the shape of an isosceles triangle and forming the small fold angle 8, the small fold angle 8 can not only effectively guide the flexible airbag 1 to expand and contract vertically but also increase the vertical telescopic deformation amplitude of the flexible airbag 1 by reducing the included angle parameter, thereby increasing the softness and hardness adjustment amplitude and meeting the usage requirements of the user for the airbag pad 5, enhancing the usage experience.

[0034] In this embodiment, the rigid airbag 2 includes at least two of the rigid bladders 4 and at least one of the flexible bladders 3, the flexible airbag 1 includes at least two flexible bladders 3, and the rigid airbag 2 and the flexible airbag 1 are arranged at the same height and are joined together to form a partition with a flat top surface at the same height. This not only ensures that the rigid airbag 2 and the flexible airbag 1 have a telescopic amplitude that meets the usage requirements but also ensures that the rigid airbag 2 and the flexible airbag 1 can expand and contract stably, preventing the occurrence of axis offset between the rigid airbag 2 and the flexible airbag 1, and ensuring that the top surfaces of the rigid airbag 2 and the flexible airbag 1 remain flat and rise and fall in a horizontal posture. In a preferred solution, the rigid airbag 2 includes three rigid bladders 4 and one flexible bladder 3 (as Figure 2 shown), and a small fold angle 8 and three large fold angles 6 are formed on the side wall of the rigid airbag 2 and are distributed successively from top to bottom. The flexible airbag 1 includes four flexible bladders 3 (as Figure 3 shown), and four lower fold angles 8 are formed on the side wall of the flexible airbag 1 and are distributed from top to bottom, ensuring that the rigid airbag 2 and the flexible airbag 1 have the same height and can be joined together to form a flat top surface of the airbag pad 5. In addition, the flexible bladder 3 is softer than the rigid bladder 4. By setting different numbers of flexible bladders 3, the overall softness and hardness adjustment range of the rigid airbag 2 and the flexible airbag 1 is improved to meet the usage needs of the user.

[0035] In this embodiment, the rigid airbags 2 and the flexible airbags 1 are arranged in a matrix and joined together to form corresponding partitions. The adjacent rigid airbags 2 or the adjacent flexible airbags 1 are connected through air channels, and the air pressure within the partitions can be adjusted synchronously. The air channels not only serve to connect the adjacent rigid airbags 2 or the adjacent flexible airbags 1, but also limit the distance between the adjacent rigid airbags 2 or the adjacent flexible airbags 1, ensuring that the distance between the rigid airbags 2 or the flexible airbags 1 within the partition is constant.

[0036] In this embodiment, there are five partitions, including a head area 9, a shoulder and back area 10, a waist area 11, a hip area 12, and a leg area 13 that are sequentially divided from front to back (as Figure 4 shown). The adjacent partitions alternately use the rigid airbags 2 and the flexible airbags 1. The head area 9, the waist area 11, and the leg area 13 are all formed by joining the flexible airbags 1, and the shoulder and back area 10 and the hip area 12 are both formed by joining the rigid airbags 2, so as to provide appropriate support for each body segment of the user and enhance the lying experience of the user. In addition, each partition can select the rigid airbags 2 or the flexible airbags 1 as needed, and by adjusting the differential air pressure to increase or decrease the support difference, so as to meet the usage requirements, which should also be regarded as the specific implementation manners of this embodiment.

[0037] In this embodiment, connection pieces are provided on the peripheral edges of the middles of the rigid airbags 2 and the flexible airbags 1. The adjacent rigid airbags 2, the adjacent flexible airbags 1, and the adjacent partitions are overlapped, welded, and adhered through the edges of the corresponding connection pieces. The rigid airbags 2 or the flexible airbags 1 form airbag strips through the overlapping and welding of the corresponding side edges of the connection pieces. The adjacent airbag strips form partitions through the overlapping and welding of the corresponding front and rear edges of the connection pieces. The adjacent partitions form an airbag pad 5 through the overlapping and welding of the corresponding front and rear edges of the connection pieces. By using the batch-produced rigid airbags 2 and flexible airbags 1 for rapid processing and assembly, the cost can be effectively reduced and the production efficiency can be improved.

[0038] It can be understood that the rigid airbag 2 includes a flexible bladder 3 provided at its bottom end, so that the rigid airbag 2 is vertically symmetrically arranged. The rigid airbag 2 is split into two vertically symmetric unit bodies. The unit body includes a rigid bladder 4 and a flexible bladder 3 provided above the rigid bladder 4. By assembling the unit bodies produced in batches to form the rigid airbag 2, the assembly efficiency can be effectively improved, the production cost can be reduced, and it is ensured that the support characteristics of the rigid airbag 2 meet the usage requirements, which should also be regarded as the specific implementation manners of this embodiment.

[0039] Embodiment 2:

[0040] Compared with Embodiment 1, this embodiment provides a mattress.

[0041] As Figure 5A mattress as shown includes a pad body, and the pad body includes an airbag pad 5 and a limit block 7 that clamps and wraps the airbag pad 5. The limit block 7 plays a role in clamping, positioning and protecting the airbag pad 5, ensuring that the airbag pad 5 is adjusted in hardness by inflating and deflating at a preset position, thereby improving the comfort of using the pad body.

[0042] In this embodiment, the limit block 7 is provided with through holes, and the number and positions of the through holes are matched one by one with the rigid airbags 2 and flexible airbags 1 on the airbag pad 5. During installation, the limit block 7 wraps the airbag pad 5, and the through holes are sleeved on the corresponding rigid airbags 2 and flexible airbags 1, so that each rigid airbag 2 and flexible airbag 1 is limited by the inner wall of the through hole, ensuring that the rigid airbags 2 and flexible airbags 1 realize vertical expansion and contraction under the guidance of the through holes, and then adjusting the softness and hardness by adjusting the air pressure to provide comfortable support for the user.

[0043] Other structures and effects of the airbag pad in this embodiment are the same as those in Embodiment 1 and will not be elaborated here.
