Description

Airbag cushion and mattress using the same Technical Field

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

[0002] Existing airbag cushions include a bladder assembly, a fixing layer adhered to the bladder assembly, and a massage airbag disposed on the fixing layer. The massage airbag massages the corresponding parts of the user by inflating and deflating air. In order to ensure that the massage airbag can accurately press the preset area, the massage airbag needs to be firmly connected to the fixing layer. The massage airbag can be fixed to the fixing layer by means of straps or adhesion. When using straps to fix the massage airbag, the two ends of the massage airbag are respectively bound and connected to the fixing layer by straps, so that the massage airbag and the fixing layer fit tightly; when using adhesion to fix the massage airbag, the bottom surface of the massage airbag is adhered and fixed to the fixing layer by glue.

[0003] During use, the massage airbag inflates and deforms, causing relative displacement with the fixed layer. Specifically, when using the strap method, the massage airbag will pull on the fixed layer through the straps at both ends, causing the fixed layer to partially warp. Long-term pulling can cause the fixed layer to tear and separate from the bladder assembly, resulting in damage to the airbag cushion and shortening its service life. When using the adhesive method, the massage airbag will deform relative to the fixed layer due to inflation and deflation, causing the glue to tear due to the relative offset of the two components. This can cause the massage airbag to shift or even roll freely within the mattress, affecting the user experience. Summary of the Invention

[0004] In order to address the deficiencies of the prior art, the present invention provides an airbag cushion and a mattress using the same. The massage airbag is fixed to a fixed layer through a fixing plate, and the deformation of the fixing plate itself is used to offset the pulling force between the massage airbag and the fixed layer, thereby ensuring that the massage airbag is firmly connected to the fixed layer, extending the service life of the airbag cushion and improving the user experience.

[0005] The present invention is implemented as follows: an airbag cushion comprises a fixed layer and a massage airbag. The massage airbag is mounted on the top surface of the fixed layer via a fixing plate. The bottom surface of the massage airbag is fixedly connected to the middle portion of the fixing plate, such that the side edges of the fixing plate are exposed and fixed to the fixed layer. The massage airbag is fixed to the fixed layer via the fixing plate, ensuring that the massage airbag can deform freely during inflation and deflation and that the fixing plate is firmly connected to the fixed layer. The deformation of the area between the side edges and the middle portion of the fixing plate offsets the pulling force exerted on the fixed layer by the deformation of the massage airbag, thereby extending the service life of the airbag cushion and improving the user experience.

[0006] Preferably, the side edges of the fixing plate are sewn and fixed to the fixing layer by stitching. The side edges of the fixing plate and the fixing layer are fixed by stitching, which not only facilitates processing and ensures a firm connection between the fixing layer and the massage airbags, but also reduces the effect of deformation of the fixing plate on the connection strength between the fixing layer and the massage airbags through the linear connection.

[0007] Preferably, the horizontal distance between the suture and the center line of the fixing plate is A, 10mm≤A≤30mm, which can reduce and offset the influence of the deformation of the massage airbag on the connection strength by increasing the horizontal distance between the two, and can also reduce the horizontal offset amplitude of the massage airbag by limiting the horizontal distance, thereby ensuring that the relative positions of adjacent massage airbags are fixed and that adjacent massage airbags do not interfere with each other.

[0008] Preferably, the stator is elongated and arranged in the same direction as the length of the massage airbag, with the sutures extending along the length of the stator. Increasing the length of the stator extends the distance between its side edges, and the longer sutures enhance the connection strength, preventing the stator from detaching from the fixing layer. A thread connects the stator to the fixing layer, facilitating deformation of the stator centered on the sutures, thereby facilitating the stator's adaptation to the deformation of the massage airbag.

[0009] Preferably, an adhesive portion is provided in the middle of the fixing plate, which is fixed to the bottom surface of the massage airbag. The fixing plate is located in the area between the adhesive portion and the suture to form a buffer portion. The buffer portion offsets the pulling force between the massage airbag and the fixing layer through its own deformation. The fixing plate is adhered and fixed to the bottom surface of the massage airbag, which not only ensures a firm connection between the two, but also prevents the adhesive portion from interfering with the deformation of the massage airbag by reducing the contact area. The area between the adhesive portion and the suture of the fixing plate forms a buffer portion. The buffer portion uses its own deformation to cope with the deformation of the massage airbag, ensuring that the buffer portion can provide offset space for the freely deforming massage airbag and also ensuring a firm connection between the massage airbag and the fixing layer.

[0010] Preferably, the bottom surface of the massage airbag is fixedly bonded to the adhesive portion by hot-melt bonding, which is convenient for processing and has good connection strength, thereby preventing the massage airbag from being separated from the fixing plate.

[0011] Preferably, two sutures are symmetrically placed on either side of the fixing plate, each secured to the fixing layer by the sutures. This allows the fixing plate to leverage its structural strength to force the bottom surface of the massage airbag into contact with the fixing layer, effectively reducing the displacement distance of the massage airbag during inflation. Buffers are formed on both sides of the fixing plate, utilizing their own elastic deformation to both pull and position the massage airbag and provide space for displacement.

[0012] Preferably, the suture is a single thread, allowing the massage airbag to be adjusted in displacement about the suture. One edge of the fixing plate is fixed to the fixing layer via the suture, while the other edge is free to move. This allows the massage airbag to have a large displacement range, ensuring that deformation of the massage airbag does not affect the connection strength between the fixing layer and the fixing plate.

[0013] Preferably, the massage airbag includes at least one unit airbag, which is connected to the outside world via an air nozzle to adjust the air pressure within the massage airbag. The unit airbag is connected to an external control box via the air nozzle to regulate the air pressure. The unit airbag can adjust the softness and hardness of the massage airbag through air pressure regulation, making it convenient for the user to adjust the massage airbag according to their needs.

[0014] Preferably, the unit airbag comprises an upper capsule and a lower capsule stacked vertically, the upper capsule and the lower capsule being bonded and enclosed by peripheral adhesion to form the unit airbag. The peripheral edges of the upper capsule and the lower capsule are fixed by high-frequency welding, which not only ensures a sealed connection between the upper and lower capsule, facilitating adjustment of the softness and hardness through inflation and deflation, but also serves as a guide for the vertical expansion and contraction of the unit airbag, ensuring that the unit airbag expands and contracts vertically, preventing interference between the unit airbags due to horizontal offset during inflation and deflation, and ensuring that the unit airbags can exert a massage force on the user by vertically extending during inflation.

[0015] Preferably, there are two unit airbags which are vertically stacked, and through holes are provided between the facing surfaces of the unit airbags so that the air pressure in the unit airbags can be adjusted synchronously. This can not only increase the intensity of the massage force by increasing the number of unit airbags, but also use multiple unit airbags to share the vertical deformation, thereby reducing the horizontal offset distance of each unit airbag.

[0016] Preferably, the fixed layer is divided into a plurality of zones from front to back, at least one of which is provided with a massage airbag. The zones include a shoulder and back zone, a waist zone, a hip zone, and a leg zone. Multiple massage airbags may be provided, each corresponding to a user's torso, providing targeted massage for each torso and enhancing user comfort.

[0017] A mattress using the airbag cushion comprises an upper quilted layer, an airbag cushion, a spring cushion, and a lower quilted layer, arranged in order from top to bottom. The mattress is provided with a peripheral edge. The upper and lower quilted layers are sewn together to wrap around the airbag cushion, spring cushion, and peripheral edge, ensuring that the mattress maintains its preset contour while also protecting the airbag cushion and spring cushion.

[0018] The beneficial effects of the present invention are as follows: the massage airbag is fixed to the fixed layer through the fixing plate, which not only ensures that the massage airbag can deform freely when inflated and deflated, but also ensures that the fixing plate is firmly connected to the fixed layer. The deformation of the side edge and the middle area of ​​the fixing plate is used to offset the pulling force exerted on the fixed layer by the deformation of the massage airbag, thereby extending the service life of the airbag cushion and improving the user experience.

Modes for Carrying Out the Invention

[0027] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0028] Example 1:

[0029] This embodiment provides an airbag cushion.

[0030] As shown in Figures 1 and 2, an airbag cushion 16 is composed of a fixed layer 1 and a massage airbag 2. The massage airbag 2 is mounted on the top surface of the fixed layer 1 via a fixing plate 3. The bottom surface of the massage airbag 2 is fixedly connected to the middle of the fixing plate 3 so that the side edges of the fixing plate 3 are exposed and fixedly connected to the fixed layer 1. The massage airbag 2 is fixedly connected to the fixed layer 1 via the fixing plate 3, which ensures that the massage airbag 2 can deform freely during inflation and deflation, and uses the fixing plate 3 to reduce the constraint of the fixed layer 1 on the deformation of the massage airbag 2. It also ensures that the massage airbag 2 is firmly connected to the fixed layer 1 via the fixing plate 3, and uses the deformation of the fixing plate 3 to offset the pulling force exerted on the fixed layer 1 by the deformation of the massage airbag 2, thereby extending the service life of the airbag cushion 16 and improving the user experience.

[0031] In this embodiment, the fixing plate 3 has an adhesive portion in the middle portion thereof that is fixedly connected to the bottom surface of the massage airbag 2. The side edges of the fixing plate 3 are sewn and fixedly connected to the fixed layer 1 via stitches 4. The fixing plate 3 forms a buffer portion 5 in the area between the adhesive portion and the stitches 4. The buffer portion 5 offsets the pulling force between the massage airbag 2 and the fixed layer 1 by its own deformation. Specifically, the massage airbag 2 is connected to the fixed layer 1 via the fixing plate 3. The buffer portion 5 is provided on the fixing plate 3. The buffer portion 5 can adapt to the deformation of the massage airbag 2 by deformation. This not only ensures that the massage airbag 2 can deform freely during inflation and deflation, providing deformation space for the massage airbag 2, but also ensures that the fixing plate 3 is firmly connected to the fixed layer 1, acting as a limiter for the massage airbag 2, ensuring that the massage airbag 2 is always within a preset range, preventing excessive deviation, and ensuring that the massage force generated by the inflation of the massage airbag 2 accurately acts on the corresponding torso of the user, thereby improving user comfort.

[0032] In this embodiment, the horizontal distance between the suture 4 and the center line of the fixing plate 3 is A, A=20mm. By increasing the horizontal distance between the two, the influence of the deformation of the massage airbag 2 on the connection strength can be reduced and offset. The horizontal offset amplitude of the massage airbag 2 can also be reduced by limiting the horizontal distance, thereby ensuring that the relative positions of the massage airbags 2 are fixed and that adjacent massage airbags 2 do not interfere with each other.

[0033] In this embodiment, the stator 3 is elongated (as shown in Figure 3) and runs in the same direction as the length of the massage airbag 2. The suture 4 extends along the length of the stator 3. Increasing the length of the stator 3 facilitates increasing the length of the suture 4, thereby improving the connection reliability between the stator 3 and the fixed layer 1. Specifically, a single suture 4 is provided on one side of the stator 3, ensuring that the massage airbag 2 can be adjusted for offset and swing about the suture 4. By increasing the range of motion of the massage airbag 2, the impact of its deformation on the connection strength between the stator 3 and the fixed layer 1 is reduced.

[0034] In this embodiment, the bottom surface of the massage airbag 2 is fixedly bonded to the adhesive portion by hot-melt bonding. Since the deformation of the bottom wall of the massage airbag 2 is small, deformation of the massage airbag 2 has minimal impact on the connection reliability between the bottom surface and the adhesive portion. This ensures that the massage airbag 2 can deform freely while also ensuring that the fixing plate 3 is firmly connected to the massage airbag 2, thereby limiting the position of the massage airbag 2.

[0035] In this embodiment, the massage airbag 2 includes a single airbag 6, which is connected to the outside world via an air nozzle, allowing for adjustable air pressure within the massage airbag 2. The single airbag 6 comprises a vertically stacked upper and lower airbags 7 and 8, which are bonded together at their peripheries to form the single airbag 6. The upper and lower airbags 7 and 8 are vertically stacked and bonded together at their peripheries, forming a sealed chamber with adjustable air pressure between the bottom surface of the upper airbag 7 and the top surface of the lower airbag 8. This allows an external control box to adjust the firmness of the single airbag 6 via the air nozzle. In addition, there are two unit airbags 6 and they are vertically stacked (as shown in Figures 4 and 5). Through holes are provided between the facing surfaces of the unit airbags 6 to enable the air pressure in the unit airbags 6 to be synchronously adjusted. This can not only increase the lifting height of the massage airbag 2 by increasing the number of unit airbags 6, thereby increasing the strength of the massage force, but also effectively reduce the lifting height of each unit airbag 6, thereby effectively reducing the horizontal offset amplitude of each unit airbag 6, ensuring that the massage airbag 2 can be vertically lifted and lowered along its axis, which should also be regarded as a specific implementation method of this embodiment.

[0036] In this embodiment, the fixed layer 1 is divided into several zones from front to back, including a shoulder and back zone 9, a waist zone 10, a hip zone 11, and a leg zone 12 (as shown in FIG6 ). Massage airbags 2 are provided in at least one zone. The user can adjust the number and position of massage airbags 2 based on their needs to ensure a comfortable massage experience. Specifically, the massage airbags 2 can be provided simultaneously in all zones, or in some zones as needed, both of which are considered specific implementations of this embodiment.

[0037] It is understandable that the parameter A can also be 10mm, 15mm, 25mm, 30mm, etc., as long as it meets the requirement of 10mm≤A≤30mm.

[0038] Example 2:

[0039] Compared with the first embodiment, this embodiment provides an airbag cushion.

[0040] In this embodiment, there are two stitches 4 that are symmetrically placed on the two side edges of the fixing plate 3. The two side edges of the fixing plate 3 are fixedly connected to the fixing layer 1, so that the middle part of the fixing plate 3 and the fixing layer 1 remain in contact with each other, effectively reducing the activity space of the massage airbag 2, thereby improving the limiting effect of the massage airbag 2.

[0041] The other structures and effects of the airbag cushion 16 in this embodiment are consistent with those in the first embodiment and will not be described in detail.

[0042] Example 3:

[0043] Compared with the first or second embodiment, this embodiment provides a mattress.

[0044] FIG7 shows a mattress comprising, from top to bottom, an upper quilted layer 13, an airbag cushion 16, a spring cushion 17, and a lower quilted layer 14. The mattress is provided with a peripheral edge 15. The upper and lower quilted layers 13 and 14 are sewn together to enclose the airbag cushion 16, spring cushion 17, and peripheral edge 15, ensuring that the mattress maintains its pre-set contour while also protecting the airbag cushion 16 and spring cushion 17.

[0045] In this embodiment, the peripheries of the upper quilted layer 13 and the lower quilted layer 14 are fixedly connected and completely wrap the airbag cushion 16 and the spring cushion 17, which not only protects and shapes the mattress but also facilitates disassembly and cleaning.

[0046] In this embodiment, the spring pad 17 is arranged below the airbag cushion 16 to provide vertical support for the airbag cushion 16, ensuring that the vertical deformation generated when the airbag cushion 16 is inflated can be transmitted upward and act on the user's surface, thereby improving the user's lying experience.

[0047] In this embodiment, the surrounding edge 15 is arranged around the spring pad 17, which not only protects the spring pad 17, but also improves the softness of the side wall of the mattress, thereby providing more comfortable support for users who rely on the edge of the mattress.

[0048] The other structures and effects of the airbag cushion 16 described in this embodiment are consistent with those of the first or second embodiment and will not be described in detail.
