Definitions

  • the present invention relates to an article for supporting the human body of the type comprising a shaped panel, hereinafter referred to with the term panel, for supporting the body and an outer cover containing the panel.
  • the article made in accordance with the present invention may be, in particular, a mattress, a seat for a motor vehicle, an armchair, a sofa, etc.
  • Such panels are increasingly appreciated by consumers both because of their hygienic and anallergic characteristics, and because of their capacity for local deformation proportional to the force applied and, therefore, the fact that they anatomically adapt to the shape of the body they support.
  • latex is used without distinction to mean both natural and synthetic latex, and so the term latex foam also means polyurethane foam or substantially equivalent materials for the production of the above-mentioned panels.
  • Such foams are often used in the production of mattresses, to which the following description refers, without in any way limiting the scope of the present invention.
  • mattresses made of such foams have a removable outer cover, that is to say, their outer cover may be removed for both washing and changing.
  • the outer cover normally has a zip extending along the outer edge of the panel.
  • the panel may be contained in a protective inner cover, normally made of fabric such as cotton or, in any case, of a breathable material to promote panel airing.
  • the outer cover also breathable, may consist of a single layer of material, but more often consists of three layers of material, and specifically of one outer layer of superior quality material, which may bear decorative patterns, one inner layer of more economical material, usually a rather thin cotton voile, and one filler layer normally made of polyester, cotton and/or other types of fibres, inserted between the internal and external layers.
  • the three layers may be combined, fixing them together by quilting or bonding (a special type of stitching).
  • the sliding occurs both between the protective inner cover and the panel and between the outer cover and the protective inner cover.
  • the sliding between the protective inner cover and the panel is most apparent due to the natural slipperiness of the fabric surface of the protective inner cover in contact with the panel.
  • the outer cover's shape stitching which defines the shape of the panel on which it is applied, no longer matches the edges of the panel as it should. This is on one hand an aesthetic disadvantage and on the other hand results in unwanted deformation of the panel, with evident serious consequences for its functionality.
  • latex mattresses due to the significant weight of latex mattresses, in particular double mattresses, and due to the form and structure of the material with which they are made (latex foams) which is not particularly rigid but easily deformed, realigning the outer cover shape stitching with the edges of the panel is very difficult and laborious.
  • outer covers and/or protective inner covers have been proposed which are impregnated on the inside with resins or similar sticky substances.
  • resins whether natural or synthetic, may be toxic, or may cause allergies or intolerances.
  • in the long-term such resins may alter the characteristics of the panel, irreversibly damaging it.
  • the aim of the present invention is to produce an article for supporting the human body, comprising a shaped panel for supporting the body and a panel outer cover, which overcomes the above-mentioned disadvantages.
  • the article for supporting the human body disclosed is in the form of a mattress 1 and comprises a shaped panel 2 for supporting the body and a breathable outer cover 3 for the panel 2.
  • the mattress 1 has a removable outer cover, that is to say, the outer cover 3 may be removed for easy washing or changing.
  • the outer cover 3 has, for example, a zip 4 extending along the outer edge of the panel 2.
  • the zip may be substituted by two Velcro strips or the like.
  • the panel 2 is of the known type and is obtained in the shape of a parallelepiped from a foam material, specifically natural latex or synthetic latex, for example polyurethane.
  • the outer cover 3 is also of the known type, and in particular may, without distinction, be of the single-layer or multi-layer type. In the latter case, not illustrated in Figure 2 , the outer cover 3 consists of one external layer of fabric, one internal layer of fabric and a thin padding filler layer made of various types of fibres, for example cotton and/or wool, inserted between the internal and external layers.
  • a cotton fabric 5 between the panel 2 and the outer cover 3 there is a cotton fabric 5, in particular, as illustrated in Figures 3, 4 and 5 , a raised grosgrain fabric, that is to say, having raised cords 6, or ribs, separated from one another by a predetermined spacing p.
  • the fabric 5 gives the fabric 5 a certain elasticity even though it is completely made of cotton.
  • the fabric 5 may be made of synthetic fibres, which may be elastic, or a mixture of cotton and synthetic fibres. Whatever the case, the fabric 5 is breathable, to promote panel 2 airing.
  • the fabric 5 has a first side 7 facing the panel 2 and a second side 8, opposite to the first, facing the outer cover 3.
  • first side 7, illustrated in detail in Figure 5 is in contact with the panel 2 and the second side 8 is in contact with the outer cover 3.
  • the second side 8 is substantially smooth, whilst the first side 7 has a plurality of loops 9, forming projections, designed to form the above-mentioned cords 6 and to give the first side 7 a friction coefficient and a roughness which prevent the fabric 5 and the panel 2 from sliding or slipping relative to one another.
  • the cords 6 constitute longitudinal projections which locally deform the panel 2 resulting in accordingly lowered zones 10.
  • the local deformation of the panel 2 is generated by the weight of the fabric 5 and of the outer cover 3, by the force with which the fabric 5 and the outer cover 3 elastically compress the panel 2 and by the latex foam's capacity for local deformation proportional to the force applied, even if the force is of limited intensity. It should also be considered that the weight of the person sleeping on the mattress contributes to increased local deformation of the panel 2.
  • the fabric 5 is obtained in the known way, not illustrated, using a machine, not illustrated, comprising two sets of needles. A first set produces the base fabric, in particular the side 8, and a second set produces the loops 9, therefore, the side 7.
  • a plurality of needles are missing from the second set, according to a succession of gaps arranged according to the above-mentioned spacing p.
  • the fabric 5 forms an inner cover for the panel 2.
  • the outer cover 3 is separate from the inner cover and covers the latter. In other words, when the outer cover 3 is removed, for example so that it can be washed or changed, the panel 2 is still contained in and protected by the inner cover made of the fabric 5.
  • Said inner cover may, in turn, be removable.
  • the fabric 5 is fixed to the inside of the outer cover 3.
  • the fabric 5 and the outer cover 3 together form a panel 2 cover which, when removed, for example so that it can be washed, leaves the panel 2 bare and unprotected.
  • Figures 1 and 2 illustrate both of the above-mentioned embodiments.
  • the side 8 of the fabric 5 is substantially the same as the side 7, that is to say, they both have raised cords 6.
  • the fabric 5 is laid over another fabric 12, in turn encompassing the panel 2 like an inner cover.
  • Said inner cover may or may not be removable.
  • the fabric 12 may be of the known type normally used to protect the panel, or substantially smooth on both sides, or, preferably, the same type as the fabric 5.
  • the fabric 5 is fixed to the inside of the outer cover 3, the side 7 of the fabric 12 is in contact with the panel 2 and the side 7 of the fabric 5 is in contact with the fabric 12.
  • Figure 7 illustrates a motor vehicle seat 13 whose panel 14, like the panel 2, is obtained from a foam material, and whose outer cover 15 covers and protects the panel 14 with a fabric 16 identical to the fabric 5 separating them.
  • the natural elasticity of the fabric 16 already highlighted with reference to the fabric 5, allows the fabric 16 to adhere to the panel 14, following its shape perfectly.
  • Obvious alternative embodiments of the motor vehicle seat 13 are seats in general and armchairs or sofas in particular.
