Description

Technical Field

[0001] The utility model relates to an airbag in the field of bedding, in particular to a supporting airbag and a mattress with a floating layer. Background Art

[0002] Many bedding articles such as mattresses or pillows use inflatable and deflatable airbags to provide elastic support or massage functions. Since the airbag is a whole, when the pressure-bearing support area contacted by the body deforms during operation, it will release the deformation by squeezing into the non-pressure-bearing support areas around it, resulting in the inability of the pressure-bearing support area to effectively play its own elastic support role, reducing the elasticity of the pressure-bearing support area and affecting the sleeping experience and comfort of the mattress / pillow. Further, these airbags lack breathable designs. When used in mattresses / pillows, the layers sandwiched on both sides of the airbag are not breathable, causing stuffiness and discomfort on the side in contact with the body, and also affecting the use comfort and experience. Summary of the Utility Model

[0003] To solve the technical problem that after the existing airbag bears pressure, the pressure-bearing support area will directly squeeze the non-pressure-bearing support areas around it to release deformation, resulting in a poor elastic support effect in the pressure-bearing support area and affecting the use comfort and sleeping experience of the mattress / pillow, the utility model provides a supporting airbag with a floating layer and a mattress using the airbag. The airbag is composed of a plurality of mutually separated floating layers in the upper part and a common base layer in the lower part. The airbag bodies of each floating layer are in communication with the airbag body of the base layer, and there is no direct connection between adjacent floating layers. They are ventilated through the common base layer. During operation, the floating layer where the pressure-bearing support area is located will not affect the floating layers of the non-pressure-bearing support areas, enabling the floating layer where the pressure-bearing support area is located to fully play its own elastic support role and improving the comfort and sleeping experience of the mattress / pillow during use. Further, the supporting airbag is also provided with a ventilation structure to improve the air permeability of the airbag. The ventilation structure penetrates the base layer and the floating layer, making it possible for the layers on both sides of the airbag to be breathable to each other, and further enhancing the use comfort and experience of the airbag and the bedding article with the airbag.

[0004] The technical solution adopted by the utility model to solve the technical problem: A supporting airbag with a floating layer, including an inflatable and deflatable airbag body, and an air nozzle communicating with the air chamber is provided on the wall of the airbag body. The feature is that the airbag body is connected and composed of a common base layer in the lower part and a number of mutually separated floating layers arranged thereon, and the airbag bodies of each floating layer are in communication with the airbag body of the base layer. The utility model changes the simple integral structure of the existing supporting airbag, divides the airbag body into a common base layer in the lower part and a plurality of floating layers arranged on the same plane in the upper part. Each floating layer is separated and independent. Any floating layer deforms independently when bearing pressure as a support area during operation, without affecting the floating layers of other non-pressure-bearing areas separated therefrom. Therefore, the floating layer under pressure can fully play its own elastic support role, improving the comfort and sleeping experience of the mattress / pillow with the supporting airbag during use.

[0005] As a further improvement and supplement to the above technical solution, the present utility model adopts the following technical measures: The bladder corresponding to the base layer is a hollow cuboid, which is formed by enclosing two long side walls on both sides, two short side walls at both ends, a top wall and a bottom wall. The air nozzle is arranged on any one of the short side walls; The bladders corresponding to the respective floating layers are arranged in a row along the length direction of the cuboid and connected to the top wall. The bladder corresponding to the floating layer is an outer cover with an open bottom. The open edge of the outer cover is continuously and hermetically fixed to the top wall around the circumference to form the corresponding bladder. And a fourth connecting section for connecting the two is provided between the open edge of the outer cover and the top wall. A ventilation hole communicating with the inner cavity of the outer cover is opened on the top wall, and a gap is provided between two adjacent outer covers. The bladder corresponding to the base layer is a cuboid with a middle hole and has four surfaces such as long side walls. The air nozzle is located on one of the short side walls. On the top wall of the base layer in the shape of a cuboid, there are a plurality of floating layers connected in a row along the length direction of the cuboid; The bladders corresponding to the respective floating layers are all outer covers hermetically connected to the top wall of the cuboid, and a gap is provided between two adjacent outer covers to separate the respective floating layers.

[0006] Preferably, a shaping structure is arranged in the inner cavity of the cuboid to hold the side walls of the cuboid when inflated, preventing the inner cavity from bulging outwards in a plane perpendicular to the inflation working direction. The shaping structure holds the side walls of the cuboid when inflated, shapes the cavity of the cuboid, and avoids the useless outward bulging of the two long side walls and the two short side walls outside the preset inflation working direction, so that the deformation generated by inflation is concentrated on the working direction for outward bulging, improving the utilization rate of airbag inflation and the effect of elastic support.

[0007] Preferably, the shaping structure includes a tab that holds the two long side walls and the two short side walls. The shape of the tab matches the inner cavity of the cuboid. The long side and the short side of the tab are fixedly connected to the long side wall and the short side wall on the same side respectively, and a second connecting section is formed between the long side and the long side wall, and a first connecting section is formed between the short side and the short side wall. The tab allows the inner cavity of the cuboid on both sides of the tab to communicate through the openings on its surface and / or the gaps provided between the inner cavity walls of the cuboid. The shaping structure is a tab that holds the inner cavity wall of the cuboid. The tab holds the two long side walls and the two short side walls of the cuboid along the edge to shape the cavity, avoiding the useless outward bulging of the two long side walls and the two short side walls during inflation; At the same time, the upper and lower sides of the tab are kept ventilated through various methods such as openings, gaps, or a combination of openings and gaps.

[0008] Preferably, the gap is formed by the intermittent connection of the tab along the periphery with the long side wall and the short side wall. Since the tab is intermittently connected along the periphery and the inner cavity wall of the cuboid, it will not be continuously connected along the periphery of the tab and the inner cavity wall of the cuboid, avoiding the formation of a closed loop due to continuous connection in a circle, resulting in sealed isolation. Thus, the cavities on both sides of the tab are separated and not ventilated. The positions without connection in the intermittent connection of the tab edge can generate gaps between the tab and the inner cavity wall, enabling ventilation between both sides of the tab.

[0009] Preferably, the tab is parallel to the bottom wall of the cuboid. There are multiple second connection segments, which are intermittently arranged along the length direction of the long side wall. The length of the first connection segment is shorter than the length of the corresponding short side wall. The tab is parallel to both the top wall and the bottom wall of the cuboid. There are multiple second connection segments connecting the long side wall and the long side, and they are intermittently arranged. The first connection segments at both ends of the tab connecting the short side walls are also shorter than the lengths of the corresponding short side walls, ensuring that there will be no continuous closed-loop connection between the tab along the periphery and the inner cavity wall of the cuboid, resulting in sealed isolation.

[0010] Preferably, air permeation channels passing through the base layer and the floating layer are provided on the bladder. The air permeation channels are hermetically separated from the bladder cavities where the base layer and the floating layer are located. Both ends of the air permeation channels extend to the top surface of the outer cover and the bottom wall of the cuboid to form two openings. By providing air permeation channels that hermetically pass through the base layer and the floating layer on the bladder, the airbag has the effect of ventilation. When the airbag is used in a mattress / pillow and sandwiched between other cushions, the cushions on both sides of the airbag can also maintain ventilation, thereby achieving the effects of ventilation and heat dissipation, and improving the comfort and experience of the mattress / pillow with the airbag during use.

[0011] Preferably, an air pipe with two open ends is inserted through the bladder. The lumen of the air pipe forms the air permeation channel. The open ends at both ends of the air pipe are hermetically fixed to the through holes opened on the top surface of the outer cover and the bottom wall of the cuboid respectively. Installation holes for inserting the air pipe are provided on the tab and the top wall of the cuboid. By inserting an air pipe with two open ends through the bladder and using the lumen of the air pipe as the air permeation channel of the airbag, and hermetically fixing the open ends at both ends of the air pipe to the through holes opened on the top surface of the outer cover and the bottom wall of the cuboid respectively, the air permeation channel is hermetically separated from the bladder cavity, and the inflation / deflation of the bladder cavity and the ventilation of the air permeation channel do not affect each other.

[0012] Preferably, 2 - 3 air pipes are inserted through the floating layer, and each floating layer is inserted with an equal number of air pipes. Each floating layer is inserted with an equal number of air pipes, and each floating layer is inserted with 2 - 3 air pipes for ventilating the part of the bladder where the floating layer is located.

[0013] The second object of the invention of the present utility model is to provide a mattress with a support airbag inside, and the feature is that the support airbag is the support airbag with a floating layer as described in one of the foregoing. When the mattress works, the floating layer in the pressure-bearing support area will not affect the floating layer in the non-pressure-bearing support area, so that the floating layer in the pressure-bearing support area can give full play to its own elastic support function, improving the comfort and sleeping experience of using the mattress / pillow; further, the ventilation structure improves the air permeability of the airbag, making it possible for the cushions on both sides of the airbag to be ventilated with each other, enhancing the comfort and experience of using the airbag and the bedding with the airbag.

[0014] The beneficial technical effects of the present utility model: By setting a separated floating layer on the airbag as an independent pressure-bearing support area to play an elastic support role, it avoids the adverse impact of the simple structure of the overall single-chamber airbag on the non-pressure-bearing area, improving the comfort of using the mattress / pillow with an airbag; further, there are also air-permeable pore channels sealed through the airbag body, enabling the airbag to ventilate, and when the airbag is sandwiched between other cushions for a mattress or a pillow, the cushions on both sides of the airbag can also ventilate to breathe and dissipate heat, enhancing the comfort and experience of using the bedding.

[0022] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0023] Embodiment 1 is as Figures 1 to 6 shown, which is a support airbag with a floating layer, including an inflatable and deflatable bladder 1. A nozzle 2 communicating with the bladder cavity 1-1 is provided on the wall of the bladder 1. The bladder 1 is composed of a common base layer 3 at the lower part and a plurality of mutually separated floating layers 4 arranged thereon. As shown in the figure, there are three floating layers 4 in this embodiment, and the bladders of each floating layer 4 communicate with the bladder of the base layer 3, and the three floating layers 4 are all on the same plane.

[0024] Since the bladder is divided into a common base layer at the lower part and three floating layers arranged on the same plane at the upper part, and each floating layer is separated and independent from each other, one of the floating layers deforms independently as a support area during pressure-bearing work without affecting the other separated non-pressure-bearing floating layers. The pressure-bearing floating layer can fully exert its elastic support function. The support airbag with a floating layer is used on a mattress / pillow, which can improve the comfort and sleeping feeling.

[0025] Furthermore, the bladder corresponding to the base layer 3 is a hollow cuboid, which is formed by closing two long side walls 3-1 on both sides, two short side walls 3-2 at both ends, a top wall 3-3 and a bottom wall 3-4. The top wall 3-3 is welded to the two long side walls 3-1 and the two short side walls 3-2 along the entire circumference through a third connection section 14. Fixing ears 12 for fixing the support airbag are provided on the bottom walls at both ends of the cuboid, and the nozzle 2 is provided on any one of the short side walls 3-2. The bladders corresponding to the three floating layers 4 are arranged in a row along the length direction of the cuboid and connected to the top wall 3-3. The bladder corresponding to each floating layer 4 is an outer cover 4-1 with an open bottom. The open edge of the outer cover 4-1 is continuously and hermetically fixed to the top wall 3-3 around the entire circumference to form the corresponding bladder, and a fourth connection section 6 connecting the two is provided between the open edge of the outer cover 4-1 and the top wall 3-3. An air vent 5 communicating with the inner cavity of the outer cover 4-1 is opened on the top wall 3-3, and there is a gap between adjacent outer covers 4-1. The aforementioned third connection section 14 and fourth connection section 6 are both welding sections.

[0026] Further, in order to prevent the inner cavity of the cuboid from bulging outwards in a plane perpendicular to the working direction of inflation, in this embodiment, the bulging is outwards in the transverse direction. A shaping structure is provided in the inner cavity of the cuboid to hold the two long side walls 3-1 and the two short side walls 3-2 when inflated. The specific shaping structure is the tab 7 shown in the figure. The shape of the tab 7 matches the inner cavity of the cuboid. The long side 7-1 and the short side 7-2 of the tab 7 are fixedly connected to the long side wall 3-1 and the short side wall 3-2 on the same side respectively. And a second connecting section 8 is formed between the long side 7-1 and the long side wall 3-1, and a first connecting section 9 is formed between the short side 7-2 and the short side wall 3-2. Both the first connecting section 9 and the second connecting section 8 are also welding sections. The tab 7 allows the inner cavity of the cuboid on both sides of the tab 7 to ventilate through the openings 10 on its surface and / or the gaps provided between the inner cavity walls of the cuboid. In this embodiment, both the openings 10 and the gaps exist simultaneously.

[0027] When the airbag is inflated, the tab holds the two long side walls and the two short side walls of the cuboid along the edge, shaping the cavity and preventing the two long side walls and the two short side walls from bulging outwards uselessly during inflation. With both the openings and the gaps existing, the upper and lower sides of the tab still remain ventilated.

[0028] Further, the gap is formed by the tab 7 making intermittent connections with the long side wall 3-1 and the short side wall 3-2 along the periphery. The tab 7 in this embodiment is parallel to the bottom wall 3-4 of the cuboid. There are multiple second connecting sections 8, which are intermittently arranged along the length direction of the long side wall 3-1. As Figure 1 shown, there are six second connecting sections 8 around the cuboid in the horizontal plane in a circle. At the same time, the lengths of the two first connecting sections 9 at both ends of the cuboid are also shorter than the length of the corresponding short side wall 3-2. The six second connecting sections and the two first connecting sections form intermittent connections between the periphery of the tab in a circle and the side walls of the inner cavity of the cuboid, which can effectively avoid the formation of a closed loop due to continuous connection in a circle, resulting in sealed isolation and separating the cavities on both sides of the tab so that they are not ventilated.

[0029] Further, in order to improve the air permeability of the support airbag so that when it is used on a mattress / pillow, the cushions sandwiched between the two sides of the airbag can also maintain ventilation and air permeability, thereby enhancing air permeability, heat dissipation, and improving the comfort and experience of use. An air permeation channel 11-1 is provided on the airbag body 1, passing through the base layer 3 and the floating layer 4. The air permeation channel 11-1 is hermetically separated from the air chambers where the base layer 3 and the floating layer 4 are located. The two ends of the air permeation channel 11-1 extend to the top surface of the outer cover 4-1 and the bottom wall 3-4 of the cuboid to form two openings. Specifically, a through pipe 11 with two open ends is inserted through the airbag body 1. The lumen of the through pipe 11 forms the aforementioned air permeation channel 11-1. The open ends of both ends of the through pipe 11 are hermetically fixed to the through holes opened on the top surface of the outer cover 4-1 and the bottom wall 3-4 of the cuboid by welding. Mounting holes 13 for inserting the through pipe 11 are provided on the pull tab 7 and the top wall 3-3 of the cuboid. 2 to 3 through pipes 11 can be inserted through each floating layer 4. In this embodiment, 3 through pipes 11 are inserted through each floating layer 4.

[0030] The lumen of the inserted through pipe is used as the air permeation channel to ventilate the airbag. The open ends of both ends of the through pipe are hermetically fixed to the through holes opened on the top surface of the outer cover and the bottom wall of the cuboid respectively, ensuring that the air permeation channel is completely hermetically separated from the air chamber. The inflation and deflation of the air chamber and the ventilation of the air permeation channel do not affect each other. During use, the through pipe needs to have greater rigidity, different from the material of the airbag body, to avoid deformation of the through pipe caused by the increase in internal air pressure in the air chamber during inflation, resulting in the reduction of the diameter of the air permeation channel or even blockage, affecting ventilation.

[0031] Embodiment 2 is a mattress with a support airbag provided therein. The support airbag is the support airbag with a floating layer described in Embodiment 1. When the mattress works, the floating layer in the pressure-bearing support area works independently to play an elastic support role, without affecting the floating layers in other non-pressure-bearing support areas, improving the comfort of using the mattress / pillow; at the same time, the ventilation structure on the support airbag enables the cushions on both sides of the airbag to be breathable, further enhancing the comfort and experience of the bedding with this support airbag.
