Definitions
- the present invention relates to a bed mattress in which it has been attempted to provide conditions for resting and supporting of the body which, from the functional point of view of the anatomy, are considered essential for ensuring maximum comfort for the body structure of a person, taking into account its widely varying constitution and characteristics.
- the composite-structure mattress may be made in accordance with different criteria, in order to satisfy the various requirements for a more or less rigid response to the weight of the body lying on the mattress and/or more generally with regard to environmental comfort (structure which on one side is cooler for the summer and on the other side warmer for the winter).
- the mattresses of this type which even today can only be manufactured on a mainly craftsman's level, as is known, are very costly.
- the mattress consisting of a plastic-foam panel, which can be manufactured with a much higher degree of automation and therefore industrially on a large scale, for this reason has a much lower cost, although its comfort characteristics are relatively limited. Attempts have already been made, in fact, to improve these characteristics by manufacturing stratified panels, using plastic-foam layers of varying porosity, but with limited success.
- US-A-3,885,258 describes a mattress of this second type in which it has been attempted to improve the comfort for the person lying on the mattress, by forming the latter as a multiple-layer panel with a flat upper and lower surface, in which, however, the middle layer, which possesses a greater elastic resistance, has an undulating configuration - but uniform thickness - the undulations being located directly opposite the undulations of the human body lying on the mattress.
- the object of the present invention is therefore that of providing a mattress of the same type as that according to US-A-3,885,258, i.e. which is made by means of the arrangement, on top of one another, of layers of plastic foam, but which however is able to satisfy in an optimum manner the comfort requirements of the human body which, with regard to what stated in the introduction, differ greatly from one individual to another.
- This object is achieved by means of the characteristic features mentioned in Claim 1.
- a further object of the invention is to provide a mattress which offers improved comfort characteristics in relation to the season, i.e. summer or winter, in which it is used. This object is achieved by means of the characteristic features mentioned in Claims 3 and 5.
- the mattress according to the invention consists of a composite panel formed by three plastic-foam layers arranged on top of one another, the middle layer 1 performing the main load-bearing function, the upper layer 2 (with reference to Figure 1) performing the function of a cool summer support surface and the layer 3 (bottom layer with reference to Fig. 1) performing the function of a warm winter support surface.
- the load-bearing layer 1 does not have a uniform thickness - as is usually the case in plastic-foam panel mattresses of the known type - but a variable thickness, which takes account of the different weight-loads of the various parts of the human body.
- the condition to be satisfied is therefore that the mattress should have varied "load-bearing" characteristics from one point to another, such that the mattress is able to flex in a varied manner under the pressure of the weight of the various regions of the body, but so as to provide an optimum response according to the load per unit of surface area.
- the mattress according to the invention has the following characteristic features:
- the invention is certainly not limited to the particular thicknesses indicated and structure of the materials mentioned above, which form only non-limiting examples of scope of the invention itself, but that numerous variations are possible, all of which within the grasp of a person skilled in the art, without thereby departing from the scope of the invention. It must in fact be remembered that the variations in the thicknesses may be modified in percentage terms, for example on the basis of the nature, in particular the load-bearing capacity, of the material used to form the three layers which make up the mattress and/or on the basis of the intended use of the mattress, i.e. for persons of short, medium or high stature.
Abstract
Description
Claims (9)
- Bed mattress, of the type consisting essentially of a stratified expanded-foam panel formed by the arrangement, on top of one another, of at least three layers with different load-bearing characteristics, characterized in that:the main layer, situated in the middle of the other two layers, has a thickness variable along the length of the mattress and is made from a material with a high load-bearing capacity;the other two external - lower and upper - layers, which each have a respective flat external surface and an internal surface which follows the profile of the main middle layer, are made from a soft material with a low load-bearing capacity;the overall load-bearing effect of the mattress being essentially determined by said middle layer.
- Mattress according to Claim 1, characterized in that said middle load-bearing layer has, on one side, a surface which is entirely flat and, on the opposite side, an undulating surface which results in said variable thickness.
- Mattress according to Claim 1 or 2, characterized in that one of said two external layers has "summer" characteristics, being formed by an open-cell foamed material with a high air permeability
- Mattress according to Claim 3, characterized in that said open-cell layer is applied onto a flat surface of the middle load-bearing layer.
- Mattress according to Claims 1 or 2, characterized in that one of said two external layers has "winter" characteristics, being formed by a soft, yielding, closed-cell foamed material.
- Mattress according to Claim 5, characterized in that said soft closed-cell layer is applied onto an undulating surface of the middle load-bearing layer, having in turn an undulating surface matching and closely adhering to the undulating surface of the load-bearing layer.
- Mattress according to Claim 1, characterized in that said middle load-bearing layer has high load-bearing characteristics with small-size closed cells.
- Mattress according to Claims 1 or 7, characterized in that the thickness of said middle load-bearing layer varies from a minimum value, in the region of the neck zone of the sleeping person, to a maximum value, in the region of the trunk and respectively the pelvis of the sleeping person.
- Mattress according to Claim 8, characterized in that said minimum thickness is about 50 mm and said maximum thickness is about 130 mm.
