WO 2006/122555 PCT/DK2006/000266 Mattress comprising an active heat absorbing/releasing layer in combi nation with a down layer FIELD OF THE INVENTION 5 The present invention relates to a mattress. BACKGROUND OF THE INVENTION During sleep the human body goes through different phases, and in these phases the body temperature varies both as a result of internal temperature 10 changes in the body during sleep and because of variations of the tempera ture in the surroundings. These temperature variations disturb the sleep. It is especially important for the sleep that the most important phase - the REM phase - is undisturbed, because in this phase the brain is recharged and pre pared for the next waken period. Another effect of the temperature changes 15 is that the quilt covering the person is kicked off during sleep, which often results in the person waking up later on freezing. Further, the temperature changes might also result in a sweaty, wet mattress. In both cases the tem perature change does not only disturb the sleep, but might also result in sick ness. 20 New materials have been developed in an attempt to address special cloth ing and other thermal regulating system requirements. For example, micro encapsulated phase change materials have been described as a suitable component for substrate coatings when exceptional heat transfer and storage 25 capabilities are desired. In US 5,290,904 substrates are described, which are coated with a binder containing microcapsules filled with energy absorbing phase change mate rial. These microcapsules enable the substrate to exhibit extended or en 30 hanced heat retention or storage properties. Also by way of example, microencapsulated phase change materials have been described as a suitable component for inclusion in fibres, when excep- WO 2006/122555 PCT/DK2006/000266 2 tional heat transfer and storage capabilities are desired. In US 4,756,958 a fibre with integral micro spheres filled with phase change material or plastic crystals has enhanced thermal properties at predetermined temperatures. This document further teaches that such fibres may be woven to form a fabric 5 having the enhanced thermal storage properties. Generally speaking, phase change materials have the capability of absorbing or releasing thermal energy to reduce or eliminate heat transfer at the tem perature stabilizing range of the particular temperature stabilizing material. 10 The phase change material inhibits or stops the flow of thermal energy through the coating during the time where the phase change material is ab sorbing or releasing heat, typically during the material's change of phase. This action is transient, i.e. it will be effective as a barrier to thermal energy until the total latent heat of the temperature stabilizing material is absorbed or 15 released during the heating or cooling process. Thermal energy may be stored or removed from the phase change material, and can effectively be recharged by a source of heat or cold. By selecting an appropriate phase change material, a substrate can be coated or a fibre manufactured incorpo rating a phase change material for use in a particular application where the 20 stabilization of temperatures is desired. One approach of solving the mentioned sleeping problem is by introducing a layer of phase change material above the core of the mattress. Phase change material has the ability of absorbing and releasing heat to/from said 25 body depending on the temperature of the body during sleep, and by using phase change material in the mattress it is the intention that temperature variations of the body should be minimised during sleep. A problem with this solution is that during sleep moist from the body is gen 30 erated and the moist is then absorbed in the layer following the phase change material, which typically either is the core of the mattress or a layer of synthetic filling between the core and the phase change material. The moist decreases the effect of the phase change material considerably, whereby the WO 2006/122555 PCT/DK2006/000266 3 introduction of the phase change material does not sufficiently solve the problem of minimising the temperature variations during sleep. US 2002/0164474 describes a composite material for cooling and insulating 5 a user in a cold environment where the material i.a. provides a path for evaporation or direct absorption of perspiration from the skin of the wearer an where one application of the composite material is described as a metabolic heating or cooling blanket useful for treating hypothermia or fever patients and therapeutic heating or cooling orthopaedic joint supports. 10 US 2003/0124318 describes a thermal barrier comprising a first barrier layer, a second barrier layer with a base material between them. As possible appli cation of the thermal barrier textiles, footwear, sleeping bags and bedding. s15 None of the above documents solves the problem with moist described above. OBJECT AND SUMMARY OF THE INVENTION It is therefore an object to provide a mattress solving the above mentioned 20 problems. This is obtained by a mattress comprising a support element, wherein said support element is covered by a first layer of a material having temperature regulating properties by absorbing and releasing heat and a second layer of 25 down. By using a material with temperature regulating properties together with a layer of down filling, very good properties of minimizing temperature varia tions are obtained. Compared to e.g. fiber filling, down filling has very good 3 0 moist absorbing properties, and by minimizing the moist tests have shown that the functionality of temperature regulating materials, such as e.g. phase change materials, is improved considerably. Thereby the temperature regu lating material can be used to fulfill the quite strict requirement to temperature WO 2006/122555 PCT/DK2006/000266 4 variation, which is necessary to get an undisturbed sleep - and especially an undisturbed REM sleep. Further, by using the temperature regulating mate rial in the mattress it is avoided that the user gets sick, both because a better sleep improves the immune system and because the risk of the person unin 5 tentionally kicking of the quilt or making the mattress wet because of sweat is reduced. Further, since the risk of the mattress getting sweaty is reduced, the frequency of which the mattress and/or mattress covers have to be cleaned can be reduced. 10 In an embodiment the temperature regulating material comprises a phase change material. This material has proven to be a good material to be used on a mattress and can be adapted to optimally minimise the temperature variations in temperature ranges around the human body temperature. s15 In an embodiment the mattress further comprises a third layer of spacer ma terial. Spacer material provides an air space between the layers above and below the spacer layer. Thereby moist can easily vanish because of air circulation from the surroundings, and the temperature regulating properties of the temperature regulating material are improved. 20 Examples of spacer material are distance mess a 3mesh@ product from Miller Textil. Using this product it is possible to adjust the hardness and the spring characteristics. 25 In an embodiment the mattress further comprises a fourth layer of spacer material, said fourth layer positioned on the opposite site of the support ele ment than the third layer, whereby each spacer material covers each side of said support element. This ensures that moist from both sides of said mat tress is minimized because of a possible air circulation around the mattress. 30 In an embodiment the second layer of down comprises goose downs. Goose downs have proven to be very good at absorbing moist, whereby the func tionality of the temperature regulating material is improved.
WO 2006/122555 PCT/DK2006/000266 5 In an embodiment the second layer has a thickness between 1 mm and 20 mm. 5 In an embodiment the third layer has a thickness between 3 mm and 50 mm. In an embodiment the mattress further comprises at least one cover layer. This protects the layer of phase change material o10 BRIEF DESCRIPTION OF THE DRAWINGS In the following preferred embodiments of the invention will be described re ferring to the figures, where figure 1 illustrates an embodiment of a mattress according to the present in 15 vention, figure 2 illustrates another embodiment of a mattress according to the pre sent invention, 20 figure 3 illustrates the functionality of the mattress according to the present invention, figure 4 illustrates the human body temperature variations when using a mat tress according to the present invention compared to the human body tem 25 perature variations when using prior art mattresses, figure 5 illustrates a further embodiment of a mattress according to the pre sent invention, 30 figure 6 illustrates a further embodiment of a mattress according to the pre sent invention, WO 2006/122555 PCT/DK2006/000266 6 figure 7 illustrates the functionality of the mattress according to the embodi ment of the mattress illustrated in figure 6. DESCRIPTION OF PREFERRED EMBODIMENTS 5 Figure 1 illustrates a mattress according to the present invention. The mat tress 101 is in contact with a large part of the human body 103 during sleep. A cross section of the mattress 101 is illustrated at 102. The mattress com prises a support element 105 e.g. a core based on foam and/or springs, wherein the support element is covered by a first layer of a material having o10 temperature regulating properties such as phase change material 107 and a second layer of down 109 The layer of down between the support element and the phase change mate rial could in one embodiment be manufactured by sewing a top layer com 5is prising the layer of temperature regulating material 107 with separating wall generating channels. Thereafter the down filling is blown into the channels and when filled, the channels are closed. As an alternative a top mattress to be placed on top of an existing spring 2 o based mattress could comprise the second layer of down filling and the first layer of temperature regulating material. Further a layer could be provided above the temperature regulating material 107 to protect the temperature regulating layer. 25 In figure 2 another embodiment of a mattress according to the present inven tion is illustrated, here beside the first layer of temperature regulating material 207, the mattress comprises a third layer of spacer material 201 positioned between the down layer 209 and the support element 205. 30 In figure 3 the functionality of the mattress according to the present invention is illustrated. The human body is illustrated at 301, the temperature regulating material is illustrated at 303 and the down layer is illustrated at 305. When the temperature of the human body 301 increases, the extra heat is stored in WO 2006/122555 PCT/DK2006/000266 7 the temperature regulating layer 303, and the body temperature is lowered. When the body temperature of the human body 301 decreases, the stored extra heat is released from the temperature regulating layer 303, whereby the body temperature is raised. Further, the down layer, being a very effective 5 moist absorber, absorbs moist from the surroundings and moist released from the human body 301. The amount of down in the layer is also used to ensure that the body temperature is kept at a specific magnitude, whereas the temperature regulating material is used to minimise temperature varia tions. 10 In figure 4 the human body temperature variations when using mattresses according to the present invention are compared to the human body tem perature variations when using prior art mattresses. On the horizontal axis the time is shown, and on the vertical axis the body temperature is shown. 15 The body temperature when using a prior art mattress is illustrated by the curve 405, whereas the body temperature when using a mattress according to the present invention is illustrated by the curve 403. Further, the interval 401 on the vertical axis is the interval defined as the optimal sleeping tem perature. By using a mattress according to the present invention, the body 20 temperature variations are minimised and kept within the optimal sleeping temperature interval 401, whereas when using a prior art mattress large tem perature variations occur. In figure 5 a further embodiment of a mattress according to the present in 25 vention is illustrated. In figure 5 another embodiment of a mattress according to the present inven tion is illustrated, here, beside the first layer of temperature regulating mate rial 507, the mattress comprises a third layer and a fourth layer of spacer ma 30 terial 501, 503 on each side of the support element 505.
WO 2006/122555 PCT/DK2006/000266 8 In figure 6 a further embodiment of a mattress according to the present in vention is illustrated, here cover layers 601, 603 are positioned as the outer parts on each side of the mattress 5 In figure 7 the functionality of the mattress according to the embodiment of the mattress illustrated in figure 6 is illustrated. The human body is illustrated at 701, the temperature regulating material is illustrated at 703 and the down layer is illustrated at 705. Further the third and fourth layers of spacer mate rial 707, 709 are illustrated on each side of the support element 708. When l0 the temperature of the human body 701 increases, the extra heat is stored by the temperature regulating layer 703, and the body temperature is lowered. When the body temperature of the human body 701 decreases, the stored extra heat is released from the temperature regulating layer 703, whereby the 15 body temperature is raised. Further, the down layer, being a very effective moist absorber, absorbs moist from the surroundings and moist released from the human body 701. The spacer material layers 707, 709 allow air cir culation through the mattress and thereby further minimises the amount of moist. 20 The mattresses can be filled uniquely e.g. based on the climate in which the mattress is to be used and based on the comfort temperature of the human being intending to use the mattress. 25 In the above description mattresses comprising down filling are described. In this connection the word down relates to both down, feathers or a combina tion thereof and should therefore be interpreted correspondingly. It should be noted that the above-mentioned embodiments illustrate rather 30 than limit the invention, and that those skilled in the art will be able to design many alternative embodiments without departing from the scope of the ap pended claims. In the claims, any reference signs placed between parenthe ses shall not be construed as limiting the claim. The word 'comprising' does WO 2006/122555 PCT/DK2006/000266 9 not exclude the presence of other elements or steps than those listed in a claim. The invention can be implemented by means of hardware comprising several distinct elements, and by means of a suitably programmed computer. In a device claim enumerating several means, several of these means can be 5 embodied by one and the same item of hardware. The mere fact that certain measures are recited in mutually different dependent claims does not indi cate that a combination of these measures cannot be used to advantage.
