Multi-layered arrangement constituting a mattress or padding, ventilated mattress including the arrangement

Abstract

The mattress / quilting system comprises a stack of layers (2) enclosed in a ticking (12) including a hydrophobic material (M2) permeable to air and water vapor to complete an internal configuration that is neither obstructive nor compartmentalized with respect to air, with ventilation passages distributed in the interstices of the filling layers of the internal volume (V). Not only is the first cushioning element (3), constituting a filling including a non-woven material (M1) of plastic filaments (5), unrestrictedly permeable to air, but also a second cushioning element (4), which constitutes a porous support layer located beneath the upper wall (P2) of the ticking, is highly permeable to air by having elastically deformable elements typically spaced apart, thus preventing water retention through such an arrangement (1).Openings through the upper surface of the ticking (12) promote upward air circulation.

Description

Title of the invention: Multilayer arrangement constituting a mattress or padding, ventilated mattress including the arrangement. Technical field

[0001] The invention relates to comfortable support equipment through a cushioning effect, for independent use or in combination with a bed or similar elevated positioning structure. More particularly, it proposes a multi-layered arrangement constituting a mattress or padding, a ventilated mattress including the arrangement, and use of the arrangement with preferential upward airflow. Technological background

[0002] To allow air circulation as close as possible to the body, an accessory forming a mattress topper has already been proposed, which is placed between the user and a mattress. US patent 5473783 shows this type of accessory, with a mesh fabric cover enclosing a thin cushion, the size of which can correspond to the middle area of ​​the bed. Air can be blown directly into the accessory, so that the ventilation bypasses the underlying mattress and is exerted near the part of the body supported by the accessory. This type of solution is not practical in use.

[0003] For example, as described in US patent 11304536, a multi-layered arrangement is known that avoids the problem of water or liquid (spilled milk, for example) accumulating in a thick cushioning layer. This is achieved by superimposing a thinner, water-absorbing layer onto a porous filling, which prevents the risk of aqueous liquid seeping into the main filling. Hydrophilic fibers are incorporated, allowing the assembled mattress to have a cottony layer.

[0004] Existing multi-layered mattresses of this type often present maintenance difficulties, for example in hotels. They can retain moisture for a long time without drying quickly. The user's comfort level is low because the layer that retains water is closest to the body. Moreover, much like with the use of moisture-resistant covers, the upper part of the mattress tends to exhibit relatively inelastic or even rigid behavior.

[0005] It is also known, for example from US patent 8881328 B2, to use layers based on a foam (typically polyurethane) for a cushioning effect, with the integration of one or more void spaces (forming at least one plenum area), to allow coupling to the mattress a ventilation device with a fluidization zone. Air can then circulate within the mattress, passing from one layer to another and using horizontal channels formed by gaps in the contact areas between two superimposed layers. This assembly, well-suited for cushioning and distributing the weight of the person lying down, is relatively complex and does not allow for ventilation close to the body. Even though a heat dissipation effect is provided within the mattress, this type of structure offers insufficient comfort in the event of perspiration or other causes of fluid absorption. Summary

[0006] In order to improve the situation, a multilayer arrangement constituting a mattress or padding is proposed, this arrangement comprising: - a ticking defining an external cover including or formed of an air-permeable material, with a top wall made of this material allowing to define a top support surface; - a lining, typically having a six-sided geometry, which is porous and compressible, preferably being perforated on all six sides, this lining forming a first cushioning element being mounted in an internal volume delimited by the ticking, possibly in a removable manner, being made of or based on a non-woven material of plastic filaments; - a porous and compressible backing layer, forming the second cushioning element and positioned between the first element and the upper surface of the ticking, the material of this compressible layer being typically different from and distinct from the non-woven material, with the particularity that the arrangement is devoid of a water retention layer, the air-permeable material in the ticking being hydrophobic, preferably in the form of a woven fabric, which is permeable to water vapor (using upper passageways in the arrangement), knowing that the second element: - is permeable to water, at least when in the form of water vapor; and - can be more flexible and / or more compressible than the lining by including elastically deformable elements the arrangement being designed and assembled so that the upper wall of the ticking and the underlying damping elements, superimposed within the arrangement, allow to form, in the said respective materials and in particular between the filaments or elastically deformable elements thereof, a network of air passages, which are interconnected, rising from a base of the first element up to outlets provided through the upper support surface, favoring an upward rather than downward air circulation, in case of overpressure of air inside the arrangement.

[0007] The ticking, typically consisting of an upper ticking element and a lower ticking element, corresponds to an external cover (outer cover of the arrangement) capable of presenting: - a disconnected configuration through at least partial separation of the two ticking elements, and - A parallelepiped-shaped envelope configuration that defines the internal volume. By opening the ticking, in its disconnected configuration, it is possible to extract—possibly separately—the cushioning elements for washing and drying, and / or for biocide treatment, heating, or appropriate flea treatment, or other maintenance operations. The aerated filament structure of the filling, with a density possibly less than or equal to 60 or 80 kg / m³, facilitates maintenance (this refers to the apparent density, which is low due to the filling's highly aerated structure).

[0008] The mattress or quilting thus made up of heterogeneous layers can combine the advantages of cushioning with a rapid return to shape, made possible by the filling, while benefiting from a comfort effect (soft support, without roughness / hardness to the touch typically), having a high level of air permeability which is important in particular for the direction of air evacuation through the upper surface, knowing that the ticking element forming the upper wall and the comfort layer constitute the areas which first suffer the impact of a humid environment.An overpressure of air inside the arrangement can optionally result from an insufflation with air flowing in from the bottom and / or from a side: it is understood more broadly that the ventilated and interconnected structure forms multiple pathways allowing, when a person (most often called a sleeper, in what follows, for simplicity) is lying on the mattress or the quilting, the flow of air created and circulating in the padding and in the comfort layer to rise and bypass the part of the arrangement compressed under the effect of weight, to finally exit through the top layer. Preferably and advantageously, the arrangement is achieved without a rigid duct, tube, or comparable closed structure within the internal volume for air circulation. Preferably, the aeration effect results from a dispersed arrangement of filaments or similar elements which: - structure the base layer or the lining, respectively, to define its thickness; and - are compatible with multiple directions of airflow (typically free flow) and / or define open porosity (notably without internal partitioning of layers or closed bubbles or cavities) in damping elements.

[0009] The upper layer / wall that delimits the internal volume from above may also exhibit an aeration effect resulting from a dispersed arrangement of filaments or similar structures which, in this upper layer, define its thickness or the spacing between two parallel sublayers. The upper layer is not partitioned and lacks closed cavities.

[0010] Preferably, the lining is the layer with the highest permeability, possibly without any directional effect on air circulation. The ticking may have a different composition between the upper and lower ticking elements, with openings provided for air circulation and evacuation at the top of the arrangement that allow for a higher level of air permeability for the upper ticking than for the lower ticking. If necessary, the thickness (total thickness) of the lower ticking element—that is, the upper wall—may be greater than the thickness of the lower ticking element.

[0011] The lower layer, consisting of the ticking (in the lower ticking element), may include additional material not present in the upper layer that forms the upper surface of the arrangement. This additional material may be a stabilizing fibrous component arranged in a thin sublayer, for example, the thickness of which does not exceed 15% of the total thickness of the lower layer. Such a sublayer typically defines the lower surface of the arrangement.

[0012] In some embodiments, the filaments of the nonwoven material (which is a different material from the material constituting the upper wall) are part of a block and / or at least one block and, to form the padding, define a parallelepiped-shaped spring-like structure that defines, according to a stacking direction of the damping elements, opposite faces of the padding. This padding may be located under the second damping element to be further from the upper wall. Possibly, several paddings of the same type, identical or differing from each other only in thickness, may be stacked under the backing layer. In other words, the first damping element is a lower element in the arrangement, possibly in contact with the lower ticking element. The filaments of the non-woven material of the trim can each have a multi-curved 3D structure, which allows for an entanglement of the different filaments.

[0013] The openings (in the upper layer) can correspond to the access points of the pores in the carrier surface formed by the material in this upper part of the ticking. In practice, an airflow blown from below can rise in the arrangement and escape from the ticking through these openings. The upper layer does not have barrier effect to gases, or at least no barrier / limiting effect on ventilation in case of overpressure of air in the arrangement. Depending on implementation options, independently or in addition to the above, one or more of the following features may be provided: - the filling constitutes the thickest layer of the arrangement. - the receiving layer has a thickness at least three times greater than the thickness of the upper wall and preferably does not exceed half the thickness of the lining. - the receiving layer, approximately 20 mm thick for example, is made of a water-repellent material that is permeable to liquid water and water vapor. - the receiving layer and the top layer form a top subset of the arrangement, the thickness (height) of which can be between 20 and 80 mm, without exceeding 90 mm for example. - the receiving layer and the top layer form a top subset of the arrangement which is more air-permeable than the bottom layer formed by the bottom element of the ticking, as measured by any appropriate permeability test carried out on these two respective parts in a disassembled state from the rest of the arrangement. - the upper subset of the arrangement allows air to circulate in an upward flow; such an upward flow is, at least in areas that are not directly above the sleeper, directed perpendicularly to the upper layer, possibly without a deflection effect or with a lesser deflection / deflection effect than in the lower layer.

[0014] In preferred embodiments, the trim, made up of said plastic filaments of the non-woven material, has: - a random arrangement of said filaments of the non-woven material; and - an air permeability greater than 200 cm3 / cm2s, preferably greater than 400 or 600 cm3 / cm2s. Typically, the upper subassembly of the arrangement can have an open structure, possibly with each of the top and backing layers including a spacing underlayer interposed between two parallel sublayers. The upper subassembly of the arrangement can optionally be configured to have an air permeability greater than or equal to 150 or 200 cm³ / cm²s. This subassembly may include or consist of woven materials with a spacing underlayer. The aforementioned permeability values ​​can each be measured according to the Japanese test standard JIS L1096 and / or the American test standard ASTM STM D737. In embodiments, the air permeability of the upper subassembly along the stacking direction is higher than a permeability threshold corresponding to at least 20 or 30% of the air permeability of the packing made of the non-woven material.

[0015] The upper subassembly of the arrangement may include or be made of a hydrophobic material distributed in a filamentary manner. Each part of this upper subassembly may have a filamentary structure to constitute a woven material. The second damping element is, for example, permeable to liquid water and to water in the form of water vapor. It is advantageous to create an arrangement with air passages in the form of a network extending across the entire width and length of the internal volume and the top layer delimiting this internal volume. Part of this network is formed by the interfilament gaps in the lining, as the ticking may exhibit greater air permeability in the upper layer compared to the lower layer. Optionally, across the entire upper surface, the ratio or surface percentage of these openings can exceed 20% or 30%, for example, 50% or higher. In the receiving layer and / or in the top layer, as well as in the filling, the composition of the filaments is devoid of water (water molecule), being devoid of hydrated function.

[0016] In implementation options for the host layer, at least one of the following provisions may be provided: - the second element consists of a woven material incorporating the elastically deformable elements and which has two parallel sublayers spaced apart by an intermediate spacing sublayer (compressible sublayer) which includes fine filaments which each have a cross-section smaller than the cross-section of the comparatively thicker filaments of the first element. - the filaments are curved and optionally have the same developed length which is greater than the total thickness of the host layer. - each of the two sub-layers, made with a wire and / or mesh structure, can have an openwork structure, for example forming openings identical or at least as wide as those obtained in an external sub-layer of the upper layer / wall. - fine filaments can constitute all or part of the elastically deformable elements, which allows the compressible host layer to exhibit greater pliability than that allowed by the filaments of the lining. - the intermediate spacing sublayer allows by default a constant spacing of the two sublayers (which serve as support for the fine filaments) along said stacking direction, so that these fine filaments are all suitable to define foldable sections delimited between two ends by extending from one to the other of the two parallel sublayers. - the intermediate spacing sublayer may consist of or include fine filaments, each of which has a "C" profile.

[0017] In an example of the embodiment of one or more trims (which overlap for example), one and / or at least one other of the following arrangements is provided: - four faces of a side wall of the trim and two other opposite faces (lower face and upper face) of the trim are made up of cut ends of the filaments of the non-woven material. - the lining allows a part of these filaments to contact, on the one hand, with one of the sub-layers of the second damping element which covers the lining, and on the other hand, against the inside of a lateral face of the ticking which extends between a bottom wall of the ticking formed in a first of the ticking elements and the upper wall which is part of a second of the ticking elements. - one of the four faces of the lining or an under face of it is opposite a ventilation fitting, in order to allow thermoregulation by circulation of a pulsed air in the internal volume, this pulsed / suffused air beginning by passing through the interstices between the filaments of the lining before diffusing on the opposite side of the lower wall or lower layer of the ticking by passing through the receiving layer and then the upper layer / wall of the ticking. The 3D structure of the gasket allows this heat flow to be transferred from the fitting to the entire open-pore volume of the gasket. Heat exchange is also enhanced by this structure of the non-woven material.

[0018] According to one particular feature, the filaments of the lining are in a thermoplastic component whose molecular chains combine a portion or motif with elastomeric properties and a polyester portion or motif, such that this component forms a thermoplastic polyester elastomer. This component may, for example, be a thermoplastic component having the following formula representative of its composition: [Chem. 1] r ca O coo(CHî) $014 co Ocoo { (ch*ou 1, where g and y are natural integers denoting the number of patterns.

[0019] Optionally, the lining can be of the Breathair® type (with a value of around 900 cm3 / cm2s for permeability, for example according to the JIS L1096 standard - and a low density, for example around 50 kg / m3). More broadly, throughout the following, it is understood that the filament molecules of the trim may combine polyether / polyester block copolymers. This may be a polymer in which a first type of component or poly(alkylene oxide) chain is bonded to a different component in the form of a polyester chain that is a polymer of a 6-carbon oxycarboxylic acid or a 2-carbon dihydroxy compound and an aromatic dicarboxylic acid. Two or more of the aforementioned components may also be used together. The weight percentages of the aforementioned components in the block copolymer used in this disclosure may be determined based on the intended purpose and end use.

[0020] In the arrangement, the ticking may be provided with a zipper or closure means with a release element for disconnecting the ticking elements. To open and deploy the outer cover, in order to release / remove the internal components of the arrangement, the ticking may have a side panel equipped with a zipper / zipper system, for example, with a first part or half of a zipper and a second part or half of a zipper. A peripheral joint is formed on at least three sides of the arrangement. It is understood that the first part and the second part are coupled for attaching the upper part of the cover or ticking element to the lower base or ticking element.

[0021] Regardless of the opening method to disconnect these elements and open the external cover, it is understood that the first damping element and the second damping element are extractable out of the internal volume (in the configuration disconnected from the external cover). Preferably, the outer cover has a difference in composition so that a lower surface of the ticking, opposite the upper surface in the parallelepiped envelope configuration, is made of a layer of fabric, preferably cotton and / or forming a less slippery surface than the upper surface, which is: - not present in the upper wall; - made of a fabric having a lower air permeability than the material of the receiving layer and / or that of the material of the upper layer / wall of the ticking.

[0022] The ticking and / or the second damping element may consist of: - two outer layers; and - of filaments resistant to or opposing the pressure between the two. The lower layer of the ticking may have a comparatively higher density than the upper layer of the ticking. The upper subset of the arrangement may feature mesh fabric sections forming the respective outlets of the main surfaces, in the upper layer and in the receiving layer. The arrangement, or at least the upper sub-assembly, can be provided without foam, that is to say without any layer of foam (polyester or polyether foam, polyurethane foam, latex foam or other).

[0023] Advantageously, in this arrangement, all the layers can have open structures, with the filling being both the thickest layer in the arrangement and the most breathable or air-permeable. The other layers only minimally reduce the permeability advantage of the main filling, which can be of the Breathair® type in a preferred embodiment. A sleeper can therefore enjoy optimal comfort with a soft / not-too-firm feel while benefiting from a healthy environment made possible by a high level of air permeability.

[0024] According to one particular feature, the receiving layer does not exceed 22 mm and / or forms less than 12% of the total thickness of the arrangement, while having a thickness greater than that of the top layer (of the ticking). Optionally, the top element of the ticking which forms the upper support surface (seating / sleeping) consists of a single woven fabric (with spacer yarns or filaments connected to two parallel outer sub-layers of this woven fabric to form a spacer sub-layer), preferably having a spacer sub-layer thickness of approximately 2 cm or less (5 mm for example). To enable the fabric or woven material of the upper element of the ticking to have a thickness less than that of the receiving layer, a sufficient thickness of the intermediate spacing underlayer is typically provided in the receiving layer, which is for example a thickness greater than or equal to 2.5 cm.

[0025] In certain embodiments, the nonwoven material of the first damping element inherently has a lower density than the material constituting the second damping element (this refers to the density of the material in the filaments, which can be on the order of 1.23 g / cm³, for example, for the filaments of the padding). However, the level of entanglement in the woven material provides for greater spacing between the filaments and / or a finer filament size, so that the woven material of the first damping element has a lower apparent density than the nonwoven material constituting the second damping element. In the second damping element, one of the two sublayers is in contact with an inner face of the ticking element (called the top layer) which forms the top of the arrangement. Regardless of the composition chosen for the receiving layer inserted into the internal volume, beneath this ticking element, the 3D structure of this receiving layer can be expected to be delimited between two parallel textile sublayers separated by a textile damping medium and / or which includes a plurality of filaments bonded between one and the other of the two sublayers.

[0026] According to another aspect, a ventilated mattress is proposed having an arrangement such as the one mentioned above with the internal volume delimited between the lower ticking element and the upper ticking element, the ventilated mattress having a ventilation means generating an airflow which flows into the padding via a passage provided in the lower ticking element (typically complementary to the upper ticking element). In particular, the mattress may include a ventilation fitting that has an opening opposite a lower or side wall of the padding, the fitting being: - supported by the one of the two ticking elements that defines a / the lower layer of the ticking; and - functionally associated with a material, preferably that of the lower layer, which is less permeable to air than the upper wall and than any of the materials constituting the damping elements, so as to allow the generation (in the internal volume) of an upward airflow which rises from a lower part or from the base of the first element.

[0027] Optionally, the ventilated mattress is temperature-regulated by including at least one radiation source (which may consist of one or more heating sub-elements) selected from a device, Peltier module, or heat emitter that is part of a heating and / or cooling air conditioning system. Preferably, the radiation source is located outside the internal volume. Independently or in addition, a heat exchanger is provided to cool a gaseous heat transfer fluid, typically air, which is circulated to flow over the padding.

[0028] According to one particular feature, the ventilated mattress is further provided with one or more functional components, such as: - a germicidal means including a plurality of UV sources and at least one strip or support for the UV sources, which are preferably light-emitting diodes emitting in the UV-C spectrum (typically above 250 nm); - a control device allowing the temperature of the receiving layer to rise below a programmed threshold, the control device being further configured to activate the germicidal agent; and - a communication interface connected to the controller device and capable of receiving commands from a remote control or a user terminal with remote control function (which allows, for example, the germicidal means to be activated for continuous operation which may correspond to the duration of a cycle set in advance).

[0029] The ventilation means may include an insert portion, housed internally within the ticking, which extends a ventilation connection and comprises one or two ducts provided with perforations and / or air-permeable areas. Such ducts may run along (on the inside) the lower element of the ticking. Optionally, one or two duct sections, preferably made of textile ducting, are provided within the duct(s). These sections are continuous and extend continuously from one end (e.g., rear, away from a head support area) to the opposite end of the arrangement. Each continuous, perforated, or air-permeable section defines a useful diffusion area for purified air, preferably exceeding a threshold, for example, with a diffusion area of ​​at least 1 or 2 dm² (possibly 3 dm² or more).

[0030] When the ticking includes the woven material, this material may by itself define the internal volume and / or may constitute the entire ticking forming the outer cover. More broadly, the ticking may also have a lower layer permeable to air and water. It may optionally be provided that a bed base or similar support for the mattress (whether or not equipped with a ventilation function) incorporates all or part of the ventilation means and / or has a structure of spaced slats with several gaps, at least one of which accommodates a connection for the ventilation means.

[0031] In an application of the arrangement, forming a mattress or padding, air is circulated upwards through each of the cushioning elements. Such an application of the arrangement can combine upward air circulation through the cushioning elements without water retention within the arrangement and upward evacuation, possibly using a difference in composition in the ticking walls to evacuate, in an assembled state of the arrangement which extends substantially horizontally, an airflow that can circulate in the internal volume primarily through an upper face of the upper wall which has air permeability: - greater than that permitted on the opposite side of the arrangement, on the side of a lower wall of the ticking; and - greater than that permitted at the maximum by the side wall which forms the side faces of the ticking.

[0032] With these arrangements, it is possible to obtain very good bedding / seating comfort, by simplifying the structure required for airflow, without rigid ductwork. Furthermore, the layered structure for the damping elements allows for the selective cleaning or, if necessary, replacement of one of the component parts of the arrangement. Another advantage is the ability to quickly, even rapidly, drain water compared to conventional mattresses. Air can circulate freely in all three dimensions of the stacked cushioning elements, drawing in and removing water without being retained by the ticking or a water-absorbing layer. (Brief description of the drawings)

[0033] Other features, details and advantages will become apparent from reading the detailed description below, and from analyzing the accompanying drawings, on which: [Fig.1] schematically illustrates, in perspective, an example of components to be assembled in an arrangement according to the invention. Fig. 2 is a schematic cross-sectional view showing an example of layer stacking to achieve a mattress-forming arrangement, in a closed ticking configuration with a user lying directly on the arrangement. Figure 3 schematically shows an embodiment option in which the mattress has a ticking that can be connected from below to a means of ventilation to allow regulation. Fig. 4 is a detailed view illustrating an example of a spacing or gap structure that can be used to form the host layer. Figure 5A shows an example of an airy structuring of a woven fabric constituting the top layer within the ticking. Figure 5B shows an example of the construction of a lower element of the ticking with a lower layer made of a material absent on the top of the ticking. Figure 6 shows an example, by no means limiting, of a top surface of a ticking that allows openings to be formed for an upward airflow in the arrangement. Figure 7 shows three curves resulting from measurements reflecting water retention over time within different layers of the same thickness (on the order of fifteen centimeters), as well as a fourth curve corresponding to an arrangement according to the invention which also presents the reference thickness. Figure 8 schematically illustrates an example of the arrangement's operation, here in an option with diffusion by use of textile sheaths or similar perforated hollow organs. Description of implementation methods

[0034] Several non-limiting examples of embodiments are set out in detail below. In the various figures, identical reference numerals indicate Identical or similar elements. The up / down direction (with the upward Z direction), the lateral Y direction, and the front / backward direction (which are orthogonal to each other) in the description of a mattress or mattress cover are given for illustrative purposes. For convenience, the up / down direction is determined to coincide with the direction of the thickness of a mattress illustrated in [Fig. 2] and similar figures, and the front / backward direction can generally coincide with the longitudinal direction of the mattress (the direction of the height of a user lying on the mattress).

[0035] With reference to Figures 1 and 2, an arrangement 1 is shown having a stack 2 of layers that may vary in thickness, in order to form a sleeping support such as a mattress or quilting. This arrangement 1 includes a padding 10 which may be formed of at least one first cushioning element 3, 3', this padding 10 being designed to be highly air-permeable, typically by being made of the most air-permeable material within the arrangement 1. An internal volume V of this arrangement may be delimited by a ticking 12, constituting the outer boundary of the arrangement 1 by defining an external cover. The trim 10 can constitute a filling part, with six faces, which fits into the internal volume V, for example to be placed on top (possibly in direct contact with) a lower element 12a of the ticking 12. The [Fig.2] shows that the two opposite faces Fl, F2 of the first damping element 3 can be made directly of the non-woven material Ml which defines the air passage gaps in this element. In some options, a single damping element 3 or a single layer is provided, including this non-woven material ML. In variants, as seen for example in [Fig.2], at least two damping elements 3, 3' can be superimposed to constitute the padding 10 and an equally air-permeable padding supplement, typically with each damping element 3, 3' composed of the same non-woven material ML or at least having the same aerated structure with plastic filaments 5 which structure this type of padding, while providing compression and damping along the Z direction, and possibly in all directions (lateral direction Y and front-to-back direction).

[0036] More broadly, such a damping element 3, 3' can be porous / permeable to air throughout its entirety and compressible by being perforated on all six sides. The lining 10, which forms the first damping element 3, can be removably mounted within the internal volume V. For this purpose, the outer cover, consisting of the ticking 12, can be provided with a disconnected configuration by at least partial separation of the two ticking elements 12a, 12b, with the ticking element 12b separating and lifting (as shown in [Fig. 1], for example) by disconnecting a zipper or similar MF closure means. provided in a peripheral junction zone between these two ticking elements 12a, 12b. A peripheral junction J is formed by extending at least on three sides of the arrangement 1, for the closed configuration of the ticking 12.

[0037] The ticking 12 contains several damping elements 3, 3', 4 within its internal volume V, in a parallelepiped-shaped envelope configuration of this ticking 12. The upper wall P2 of the latter may be made of a material M2, preferably a woven material, distinct from the non-woven material M1 of the first damping element 3 and is positioned so as to be separated, along the stacking direction / Z direction, from the first damping element 3 or 3'. The upper wall P2, which extends parallel to the lower wall PI provided in the lower ticking element 12a, makes it possible to define an upper surface S12 for supporting the arrangement 1. This upper surface S12 is perforated so as to form pores or openings 012, as in the non-limiting case of [Fig. 6].

[0038] With reference to Figures 5A, 5B and 6, according to one construction aspect of the upper ticking element 12b, a three-layer composition is provided, with: the first layer 21 comprising a knitted mesh construction with a plurality of holes or openings 012 formed entirely from the yarns or filaments of the fabric or woven material M2. The holes or openings 012 can be knitted to have one or more sizes, and the size of the holes or openings can be variable or uniform over the upper surface S12 defined by this first layer 21. As shown in [Fig. 5A] and [Fig. 5B], the holes or openings 012 can be provided with no depth, so that they communicate directly with an air circulation zone formed by the gapping or spacing layer L6.A plurality of filaments 6, curved and together having an elastic rebound effect, extend through the thickness of this ticking element 12a to form the underlayer L6. The openings 012 are then in fluid communication with the underlayer 22 (forming the inner face of the element 12b) and then with the upper face of a second damping element 4. In the arrangement 1, this second damping element 4 is intended to constitute the receiving layer or padding, to provide a soft and enveloping effect superior to the effect of indentation on a first damping element 3, 3' without the receiving layer.

[0039] In preferred options, the firmness of the support layer formed by the second damping element 4 is less than the firmness of the first damping element 3,3': this means in this case that the intensity with which the arrangement 1 reacts to the pressures of the sleeper's body(ies) is reduced by the support layer, at least initially. The second damping element 4 constitutes a porous and compressible layer, thicker than the upper layer or wall P2, to allow the soft welcome effect (with the impression of sinking in when lying down compared to arrangement 1). Since the second damping element 4 is positioned between the first damping element 3 and the upper wall P2, it is typically permissible to form an upper subset of the arrangement 1, consisting of: - the structured layer, possibly in three sub-layers 21, L6, 22, of the upper wall P2 provided in the upper ticking element 12b; and - the receiving layer formed by the second damping element 4, optionally with a structure also in three sub-layers 8a, 80, 8b ([Fig.4]) as described in a little more detail later.

[0040] Not only are the plastic filaments 5 of the first damping element 3, 3' made of hydrophobic material and / or have no water retention effect, but the upper subassembly is also devoid of a water retention layer. The second damping element 4 includes elastically deformable elements that make it highly flexible and / or more compressible than the padding 10. The elastically deformable elements can each be in an arrangement that is loosely folded within a spacing sublayer, so as to form an intermediate sublayer 80 ([Fig. 4]) that spaces two parallel sublayers. This type of sublayer is aerated and has an arrangement of the elastically deformable elements that is neither stretched nor compressed. Elastically deformable elements can have a variable geometry but with sufficient spacing along the Z direction at rest to give a thickness, which can be greater than that of the ticking 12 or at least of the upper ticking element 12b, within which air can circulate in the directions (typically all directions) perpendicular to the Z direction. The thickness e4 can be greater than the mesh size forming the outlets 012 of the top of the arrangement 1 and possibly greater than a diameter or characteristic size of upper meshes / openings 20 of this damping element 4 (with this mesh size being on the order of millimeters or at least greater than 0.3 or 0.5 mm to leave sufficient spacing favorable to an airflow exiting the upper sub-assembly from the top (see arrow FL1).

[0041] The arrangement 1 is permeable to air in the Z direction, in particular by allowing air flowing into the lining 10 to circulate away from the lower wall PL. The arrangement 1, in its entirety, is devoid of a water retention layer: this advantageously avoids hindering air circulation, which can also circulate in a network of air passages formed by the layers of the upper subassembly and each first underlying damping element 3, 3'. These air passages, in the network of passages (including interfilament gaps) are thus interconnected, with a configuration of these passages which establish an upstream communication from a base B of the first damping element 3 up to the outlets 012.

[0042] In the event of overpressure, it is understood that the air present in the arrangement 1 can freely escape upwards, for example from the base B, and finally escape from the internal volume V by passing through the upper wall P2 via the openings 012 provided through the upper support surface S12. This network can be delimited at the bottom by the lower ticking element 12a, for example at the level of a meshed underlayer 22' of the latter, and laterally by a side wall PL of the ticking 12, possibly in such a way as to favor an upward rather than downward air circulation, in the event of overpressure of air inside the arrangement 1. Furthermore, water vapor can also flow freely through the layers, respectively of the upper sub-assembly and those formed by the plastic filaments 5 of the non-woven material M1, in the sense of the first damping element(s) 3. The woven material M2 is highly permeable to air while being hydrophobic. The size of the openings 02 allows for the evacuation of liquid water or water vapor through this hydrophobic woven material M2, taking into account gravity (flow in the downward direction opposite to the Z direction) and the lateral interconnection between the passages or gaps in the network. In other words, the water vapor permeability is high: - thanks to the holes or openings 012 of the knitted mesh and the underlying interstices which form upper passageways of the arrangement 1; - and thanks to the interconnected nature of the network of gaps, forming an open porosity in the upper sub-assembly and in each first damping element 3, for an omnidirectional air escape effect which allows: - lateral circulation and evacuation (see arrows FL2 on [Fig.2] for the effect of aeration and gas evacuation on the sides) of water vapor, the lateral circulation being possibly combined with an upward movement of this vapor through the areas bypassing the sleeper.

[0043] Since the non-woven material block M1 is formed by the plastic filaments 5, the ventilation effect provided by the lining 10 and / or the additional lining is omnidirectional and can propagate immediately, or after lateral movement, into the upper layers by vapor ascent. In the case of an arrangement 1 that supports a sleeper in a contact zone, water vapor can flow into the upper sub-assembly from the contact zone and then reach the lining 10 (this movement may represent a downward stroke (along the Z direction) of less than 25 or 35 mm in the thickness of the arrangement 1, which may bifurcate / deviate before rising): - in the receiving layer, which is porous and compressible, and which is the second damping element 4, - then in the upper wall P2 until the evacuation. In [Fig.2], a ventilated mattress 15 can be seen in use with the sleeper lying lengthwise, directly on the arrangement 1. When air is supplied through a fitting R3 mounted on a periphery of the ticking 12 (or, equivalently, coupled to the lower wall PI, from below as in the option of [Fig.6]), an upward airflow FA can be formed in a generally upward direction of circulation in the non-woven material M1 and with possibilities of bypassing the most compressed area underlying the sleeper.

[0044] The airflow FL1 exiting through the outlets 012, from the top, can be predominant, which helps to expel or remove: - PM particles which tend to accumulate in the sleeper's environment as sleeping time increases, - and / or simply move the air (usually warmed and less healthy air) away from this area. In the internal volume V, the airflow Fa encounters no barrier due to the aerated structure of the damping elements 3, 3', 4 and the upper wall P2 typically formed with outlet delimitation meshes 012.

[0045] The ticking 12 may be entirely composed of a fabric, possibly with an additional layer, on one or more faces that are distinct from its upper face. On the upper surface, the fabric or woven material, which encloses the backing layer and the underlying lining 10, may be directly visible to the naked eye, forming the upper surface S12, without being covered by any hydrophilic or water-barrier material. Thus, the upper surface S12 with the holes or openings 012 avoids any water barrier effect. The upper ticking element 12b is sufficiently porous to be permeable to water vapor and, preferably, also to liquid water. Example of non-woven material composition

[0046] Each damping element 3, 3' of the padding placed under the support layer can be breathable / air-permeable by being made essentially or solely of three-dimensionally stretchable plastic filaments 5, for example, by having a structure formed by the three-dimensional fusion of filaments (threads) in thermoplastic resin without tightening these filaments 5 of the ML material. The damping element 3, 3' then exhibits high porosity and thus excellent air permeability. The manufacture of such a filament structure can be carried out in the same way as, or similarly to, the manufacturing method of the commercially available Breathair® product manufactured by TOYOBO Co., Ltd. The format The parallelepiped shape of the padding 10 is obtained using a size (typically with a cut) adapted to the desired thickness and dimensions of the mattress or mattress, for adaptation within the internal volume of the ticking 12. In some cases, several blocks can be associated within the same layer forming a first cushioning element.

[0047] More generally, the material Ml is a nonwoven fabric, possibly made of a UV-resistant thermoplastic component and with filaments 5 that can reach or exceed a length of 500 or 600 mm, meaning that each filament is typically folded at least twice, with a random arrangement of the filaments 5. With this open structure, the material exhibits an air permeability greater than 200 cm³ / cm²s, preferably greater than 400 cm³ / cm²s. The arrangement 1 can thus have at least 60 or 70% of its thickness made up of the nonwoven material Ml having at least this level of air permeability.In the upper sub-assembly which can directly cover this non-woven material Ml (or at least without including or interposing a water barrier or water-absorbing layer), a good part of the remaining thickness is then also made up of gaps between the filaments or similar individual components used to delimit the interstices which allow the formation of ventilation passages up to the outlets 012.

[0048] In the illustrated examples, a correspondence is provided so that the second damping element 4 can cover the entire lining 10 formed by the first damping element(s) 3, 3'. The thickness of the first damping element 3 can be greater than or equal to 50 mm, preferably allowing a lining 10 to be obtained that represents more than half or even more than two-thirds of the total thickness of the arrangement 1.

[0049] With reference to [Fig. 1], a first damping element 3 can extend so that its periphery runs along the side wall PL ([Fig. 3]) of the ticking 12, presenting two parallel faces FL that can correspond to the length of the ticking 12 and two opposite faces F10, front and rear, also parallel. More broadly, the thickness or height of the side wall of the padding 10 is constant and can define the thickness of the padding 10, between two other opposite faces Fl, F2. All these faces Fl, F2, FL, F10 can be formed by the cut ends 5a of the filaments 5. Figure 2 shows an arrangement 1 with two damping elements, element 3 and 3', which, within the padding 10, each allow direct contact of a portion of the filaments 5 with the side wall PL of the ticking. Also, a first damping element 3 comes into direct contact with the underside of the second damping element 4, for example by supporting a sub-layer 8a of the second damping element 4.

[0050] To facilitate a liquid or water drainage effect, the filaments 5 can be based on a thermoplastic whose molecular chains combine an elastomer portion and a polyester portion, so that the non-woven material M1 forms a thermoplastic polyester elastomer. The filament structure is easily obtained by injection molding all the filaments from a plate or injection mold section equipped with an array of injection heads. These long filaments (initially stretched vertically) are then immersed in a solution to fold (the plate can be moved towards the bottom of the bath, adjusting the desired thickness) and interlock randomly before final cooling. Non-limiting examples of plastic materials that can be used to produce the non-woven material M1 are commercially available and include “PELPRENE” (registered trademark) manufactured by TOYOBO Co., Ltd. and “HYTREL” (registered trademark) manufactured by DU PONT-TORAY CO., LTD. Hydrophobic layers of the upper subassembly

[0051] With reference to [Fig. 4], the receiving layer is a hydrophobic, ventilated layer that may have a thickness e4 intermediate between that of the upper wall (lower) and that of at least one first damping element 3, 3'. The receiving layer may have a breathability equal to or greater than that of a dry surgical mask and is formed of a hydrophobic woven material with mesh underlayers 8a, 8b and an intermediate underlayer 80 less dense than the mesh underlayers. The second damping element 4, which forms this support layer with a support surface Sa (upper surface) in contact with the upper ticking element 12b, is, for example, completely permeable to water. The hydrophobic character of the second damping element 4 can be conferred both by the plasticity of the mesh underlayers 8a, 8b and by the filaments 6' which are distributed in the intermediate underlayer, forming a compressible spacing between the two underlayers 8a, 8b. A woven material SP can be used to obtain this second damping element 4, possibly with a composition and / or structure similar to that of the upper wall P2, possibly differing only in the thickness of the underlayer 80, which is thicker than the underlayer L6.

[0052] More broadly, the woven material and / or the materials of the upper subset of arrangement 1 may consist of a thermoplastic containing, as its main component, a unit that does not include a polar group, such as a hydroxyl group, having a strong affinity for water (here, a polar group at one end of the polymer is not considered), and the thermoplastic constitutes a material hydrophobic having low hydrophilicity (low surface energy and high hydrophobicity), so that it is not likely to adsorb water (easily repels water).

[0053] Examples of hydrophobic materials include, but are not limited to, polyester, nylon, acrylic, polyethylene, and polytetrafluoroethylene. Generally, the upper sub-assembly may exhibit a higher hydrophobicity than the non-woven material layer M1. Conversely, a lower, outer layer, here in the form of a CC fabric layer, can be incorporated into the lower ticking element 12a to cover the outer underlayer 23, as shown in [Fig. 5B], with reduced hydrophobicity or hydrophilicity. It should be noted that, otherwise, the lower ticking element 12a can have a similar or identical structure to that of the upper ticking element 12b, in order to allow ventilation in the downward direction as well (see also arrow FL3 in [Fig. 2]). More broadly, the second damping element 4 can consist of a woven material incorporating elastically deformable elements, such as filaments 6', and which has two parallel underlayers 8a, 8b separated by the intermediate spacing underlayer 80, which includes these filaments 6' (thin filaments compared to the thicker filaments 5).

[0054] As in material M2 with filaments 6, it can be noted that the filaments . 6' can each have a section smaller than the section of the filaments 5 of the first element 3 and / or 3': they are less thick and can thus offer a reaction with a soft effect, when the sleeper is installed / put down, superior / improved compared to the reaction conferred by a filling 10 which would directly support the upper ticking element 12b. Figure 1 illustrates in detail the delimitation of the meshes or openings 20 in the upper meshed sublayer 8b. The meshes are distributed along a plane or along the general extension of the arrangement 1, perpendicular to the Z direction. The openings 20 can be substantially the same characteristic size as the outlets 012 (an example of which can be seen in Figure 6). For the fabric layer CC or lower wall PI, a tighter mesh structure can be provided, resulting in a locally reduced air permeability under the first damping element 3, being lower than the air permeability of the material M2.

[0055] In one embodiment, the second damping element 4 is arranged above the core or lining of the arrangement 1, forming a softer damping pad. In principle, any woven material with a spacing underlayer can be suitable for forming this second damping element, from when it has significant air permeability while having sufficient comfort properties (soft and gentle feel / non-noise generating). As a non-limiting example, the 3DEA® polyester fabric from the manufacturer Essedea in Wassenberg (Germany) can be used as a woven material forming two parallel sub-layers separated by a spacer sub-layer. With a compressible layer made of this fabric, the second cushioning element (4) meets numerous bedding criteria, including adapting to the shape of the load applied to the mattress, with a springback effect to return to its initial configuration when the load is removed. In this case, it can consist of PET yarns or other polyester material (monofilament), which are pressure-elastic elements, combined to form a three-dimensional spacer fabric.

[0056] In general, the second element 4 can be chosen for its ability to: - maintain the shape with two parallel sub-layers 8a, 8b; - exhibit excellent point elasticity; and - allow for strong pressure attenuation. Moreover, woven material of this type can exhibit resistance to abrasion and wear.

[0057] More broadly, it is envisaged that each constituent material of the ticking 12 and the cushioning elements 3, 3', 4 can withstand moisture and heat, at least without alteration at temperatures below or close to 60 or 65°C. The material of the ticking 12 and / or the cushioning element 4 for forming the support layer can be hygienic (with the possibility of washing at a maximum temperature of 60°C). In addition to their excellent resilience, the materials M1 and M2 used in the composition of arrangement 1 can be homogeneous in their width and length distribution: this allows for perfect pressure distribution and contour adaptation, with tailored comfort. The significant number of hollow areas or internal passages in the various layers of the cushioning elements 3, 3', 4 and the upper P2 layer of the ticking provides optimal comfort by allowing air to circulate within arrangement 1 and optimal pressure / reaction relief.

[0058] In preferred embodiments, arrangement 1 dries rapidly when a significant amount of water is introduced. Figure 7 shows drying test curves T1, T2, and T3, which were carried out respectively (for the same thickness and overall dimensions): - for a hydrophobic polyurethane foam (Tl test curve), with a water retention that remains very significant 24 hours after the start of the test; - for a porous component based on polyester fibers (T2 test curve), with a water content that drops quite rapidly but without driving the water deep, with a stagnation effect after 3 hours while the percentage of humidity can still be greater than 50% in the pores; - for a component made solely of non-woven material of type Ml, here in particular Pelprene® of the Breathair® brand; which repels water very clearly in barely 2 hours, as seen with the T3 test curve.

[0059] The arrangement 1 with the ticking 12 enclosing the first cushioning element(s) 3, 3', preferably made of non-woven material M1, and the second cushioning element 4, corresponds to the fourth test curve T4, reflecting the moisture measurements with a capacity to dry rapidly, significantly so after a period of barely 3 hours. For this type of test, the structure of the upper sub-assembly can be based on a woven material with wide / open mesh and respective underlayers 80 and L6 spacing: the second cushioning element 4 is then detachable and washable, like the first cushioning element(s) 3, 3'. Use(s) of the arrangement as a ventilated mattress

[0060] With reference to Figures 2 and 3, the arrangement 1 is associated with a control unit, for example in the form of a ventilation system 31 equipped with a controller device activating different operating modes of an air inlet communicating with all the passageways, in order to constitute a ventilated mattress 15. This mattress 15 may include a ventilation connection R3 coupled to the arrangement 1. The connection R3 may be of the exhaust plenum type or a supply connection. The connection R3 may include ventilation equipment, possibly supplemented by a temperature modification element, such as an electric heating element located in the connection R3 or in a supply passage or duct leading to the connection R3. The equipment 9, which allows the air to be supplied and typically manages a flow rate and / or one or more physical parameters of the air supply (including the temperature level, for example), completes the arrangement 1.It may optionally be removable / detachable to separate from the arrangement 1, with the possible exception of all or part of the R3 fitting which may be permanently fixed to the ticking 12. This may allow for seasonal use if required. In certain options, for example when integrating components of the equipment 9 into the internal volume V, these can be removed by disconnecting the ticking 12 and removing the components which adhere to one of the layers or are housed in cavities located in the bottom of a layer / element 3, 3' of the lining 10.

[0061] The fitting R3, for example, has an opening opposite a wall of the fitting 10, which may be the lower face Fl or one of the side faces FL, F10. This For example, fitting R3 is supported by the lower ticking element 12a. A compressor or an airflow circulation device (e.g., a fan) may be provided within the ventilation system 31, which forms all or part of the control unit. This ventilation system 31 preferably includes a control system to adapt the heating or cooling of the internal volume V, and in particular the landing layer, according to parameters and / or commands entered using a communication interface 30, such as an HMI (human-machine interface). If necessary, a heat exchange zone and / or a heating component can be provided in a plenum or in an air supply block 32, which may include the R3 fitting or be connected to it. A fan, typically with low / very low noise emission, can also be placed in this type of block 32 to limit the additional bulk outside the internal volume V. Although [Fig. 3] shows a single opening 01 in the ticking 12, through the lower CC layer, the air intake can of course be distributed differently, with inlets that can be distributed as in the case illustrated in [Fig. 8], by using a network of suitable supply channels or RL ducts, possibly textile ducts.

[0062] In [Fig. 3], it can be seen that the communication interface 30 interacts with the controller device for managing the operating modes of the ventilated mattress 15. It allows the input and selection of an operating mode, typically from among several pre-recorded modes, and communicates with or actuates the controller device of the ventilation system 31. When regulation is provided, one or more temperature sensors or probes may be present and configured in conjunction with the controller device of the ventilation system 31. A remote control or a terminal (mobile phone configured with a dedicated application) is preferably used for input, typically with a display function to show at least certain parameters, including representative temperature information, and to display the selected mode.

[0063] In addition to its ventilation function, the mattress 15 can also be equipped with localized diffusion / injection equipment for sanitizing products or any suitable germicidal means. Referring to [Fig. 8], the mattress 15 can include, directly in a lower part of the arrangement 1, for example, RL ducts for distributed air supply, with the option of distributing treatment sections supported or connected to such ducts. In addition or as an alternative, this lower section may include a plurality of germicidal radiation sources 33, such as distributed UV sources and / or at least one strip, sheath or support (which may optionally run alongside the RL sheaths) or longitudinal zones formed at the bottom of the trim 10 (in some embodiments), equipped with UV sources to allow emission of a substantially continuous beam, for example, extending along the entire length of the trim 10. Such support bands / means may be distributed across the width of the trim 10, or alternatively along its length or diagonally with varying lengths between the radiative bands or supports. Optionally, these UV sources are or include light-emitting diodes (LEDs) emitting in the UV-C spectrum. An emission spectrum with a peak at 260 nm or including at least one peak in the region exceeding 250 nm may be selected for the UV source(s).

[0064] The controller device can, where appropriate, allow the temperature of the receiving layer to rise, while not exceeding a programmed threshold, and may also (simultaneously in certain options) activate the germicidal means. The germicidal effect can be achieved by any integrated UV-C radiation equipment (suitable lamp with a flat surface typically conforming to the lower face Fl of the lining 10) or other suitable radiative technology, which may correspond to a sanitization mode available via the control / communication interface 30. This equipment is placed, for example, beneath the lowest damping element 3 in the internal volume V.Other treatment methods using only ventilation with heating (via connection R3 or similar inlet zone in internal volume V), with suitable light radiation or germicidal radiation sources, can be implemented, preferably without the emission / release of chemicals to be carried into the incoming airflow. In some implementations, the injection of a germicidal product is permitted by using an air circuit. The circuit can, for example, be branched or have diffusion sections distributed in different zones of internal volume V, with an improved diffusion effect.

[0065] One or more R3 fittings are provided. Each R3 fitting can be functionally associated / anchored to a material, preferably that of the lower layer CC, which is less air-permeable than the upper wall P2, so as to obtain, in a ventilation mode with inlet from below or a suitable area of ​​the lining 10, an upward airflow Fa that rises from / away from a base B of the first damping element 3. Each airflow supplied from an R3 fitting can rise and widen (along the two directions perpendicular to the Z direction) as it moves away from the R3 fitting. In options with an integrated air diffusion network (as in [Fig. 8]), such a widening effect is also obtained but with a smaller radial widening / dispersion amplitude.

[0066] In the example of [Fig.8], the sources 33 and the RL ducts can be combined in the same support in electrical and fluidic connection with the ventilation system 31. The perforations and / or air-permeable areas for each RL duct can be integrated into a thickness of duct material, preferably without forming protruding reliefs on the external surface of the duct. Optionally, two continuous (possibly straight) sections of textile duct are provided, forming all or part of at least one duct RL, and each extending continuously from the rear end to the front end along the FL face. The cumulative passage cross-sections can define a significant effective purified air diffusion area, preferably exceeding a threshold, for example, with a diffusion area of ​​at least 1 or 3 dm².

[0067] It should be obvious to those skilled in the art that the present invention allows for embodiments in many other specific forms without departing from the scope of the invention as claimed. For example, although examples of realization of arrangement 1 have been illustrated with a single-block packing 10 to form the first damping element 3 and possibly one or more additional damping elements 3', it is understood that the packing layer may result from an assembly of sub-blocks designed separately and juxtaposed against each other in the internal volume V, possibly with variations in density or composition within the sub-blocks if this can customize / distribute the damping effects differently.

[0068] Furthermore, the arrangement 1 can be configured to allow the joining of two mattresses placed side by side, by placing an arrangement 1 (forming a mattress) next to a mattress or padding, of the same type / composition or not, given that the arrangement 1 includes a fastening interface that allows the two mattresses to be joined together to form a unit, for example, a double mattress. The fastening interface can be integrated into or mounted on the ticking 12 (possibly by sewing), and may include a set of hook fastening strips (of the hook and loop or Velcro type) offering sufficient strength to prevent accidental detachment. Snap fasteners and / or other fastening means can be provided in the fastening interface, for example, arranged on a suitable side and / or face, preferably without interfering with the upper surface S12 of the arrangement 1. A system of wedges can optionally be provided to install such a mattress set (for two twin beds or similar) in a stable manner on a bed base, to complement the stabilizing effect provided by the fixing interface. Wedges with a deployable configuration (to extend downwards, for example) can be provided.
