Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The characteristics and advantages of the invention are clearly evident from the following detailed description of preferred embodiments thereof, with reference to the accompanying drawings, in which:

[0029] FIG. 1 is a first rest support with comfort effect in a configuration as backrest and seat cushions of a sofa according to the invention;

[0030] FIG. 2 shows a second rest support with comfort effect in a mattress topper configuration according to the invention; and

[0031] FIG. 3 shows a third rest support with comfort effect in a mattress configuration according to the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] Herein, the measures, values, shapes and geometric references (such as perpendicularity and parallelism), when used with words like about or other similar terms such as approximately or substantially, are to be understood as except for measurement errors or inaccuracies due to production and/or manufacturing errors and, above all, except for a slight divergence from the value, measure, shape or geometric reference which it is associated with. For example, said terms, if associated with a value, preferably indicate a divergence of not more than 10% of said value.

[0033] In addition, where used terms such as first, second, upper, lower, main and secondary do not necessarily refer to an order, a priority relationship or relative position, but may simply be used to more clearly distinguish different components from each other.

[0034] The measurements and data presented herein are to be considered, unless otherwise indicated, as made in Standard International Atmospheres ICAO (ISO 2533).

[0035] With reference to the Drawings, reference numeral 1 globally denotes the rest support with comfort effect according to the invention.

[0036] The support 1, in general, is suitable to allow the support of a user in such a way as to support the same in sitting and/or lying down, and therefore, preferably, may be an object chosen between a sofa 5, an armchair, or other furnishings or components of means of transport equipped, like a sofa, with backrest and seat cushions provided for such purpose, a topper 6 and a mattress 7.

[0037] The sofa 5 has a seat 50 and a backrest 51.

[0038] The seat 50 is the support part on which the user completely offloads his weight, while the backrest 51 is the part suitable to support the user's back.

[0039] The topper 6 and mattress 7 instead have a single portion, structurally undivided.

[0040] The support 1 preferably comprises a first layer 2, a second layer 3 and a third layer 4. But it may also comprise only a first layer 2, as most frequently, but not exclusively, takes place in the topper configuration 6 of said support 1.

[0041] Preferably, the second layer 3 is between the first layer 2 and the third layer 4.

[0042] In particular, preferably, the first and third layer 2, 4, preferably with comfort functions, consist of a lesser stiffness than the second layer 3, preferably with support functions.

[0043] The first and third layers 2, 4 therefore preferably comprise a cohesive stratum.

[0044] This cohesive stratum preferably comprises material in chips, flakes, fibres and the like, and is made, more preferably by means of a thermo-fusion, low melt process.

[0045] This procedure is generally obtained by means of bi-component or polyethylene/polyester polyester binding materials (COPET/PET or PE/PET), but also others.

[0046] The cohesive stratum is preferably further processed with an air laid technology.

[0047] The air laid technology provides, for example, for laying the materials of the cohesive stratum onto suction roller belts and, in detail, comprising a material chosen from among down, feathers or other materials in chips, flakes, fibres and the like, such as wool, cashmere, Tencel, kapok, polyester, polyamide and miscellaneous mixtures thereof, made in the following ranges of thickness from 5 mm to 15 cm and weight relative to the surface from 3 dag/m.sup.2 to 1 kg/m.sup.2.

[0048] Both the down and the feathers and other materials in chips, flakes, fibres and the like mentioned above can be refined material, more or less noble, or waste material, and are intended to be transformed into a cohesive stratum in the first and third layers 2, 4, so as to achieve a stiffness less than the layer 3, and suitable to fulfil its main function of conferring comfort for a user.

[0049] In the case in which the support 1 is a sofa 5, the layers 2, 3, 4 are comprised within at least one, as desired, out of the seat 50 and the backrest 51 of the sofa 5. Preferably, therefore, at least one out of the first and third layers 2, 4 constitutes a padding portion, with a main comfort function, for at least one chosen as desired out of the seat 50 and backrest 51.

[0050] In the case in which the support 1 is composed instead of a topper 6 or a mattress 7, at least one out of the first and third layers 2, 4 defines the padding portion of the mattress 6.

[0051] In an alternative configuration to those described, preferably with three layers and, in the case of topper, more frequently, but not exclusively, a single layer, the third layer 4, may lastly possibly have the same characteristics as the second layer 3, or be completely absent.

[0052] In this case, the layer 3 comprises materials known to the current state of the art.

[0053] The rest support with comfort effect 1 according to the invention achieves important advantages.

[0054] In fact, the invention allows the creation of supports 1 suitable to overcome the drawbacks of the known art and, in particular, makes it possible to obtain a rest support with a conformation such as to allow the use, for the same effect, of more economical, natural and more environmentally friendly padding materials, in the layer used to give greater comfort.

[0055] In addition, the support 1 allows the creation of a less complex structure, compared to the prior art, of the rest support, especially in the case of the cushions of the backrests, seats and toppers.

[0056] Regardless of the padding material used, in the current state of the art in the layer used to give greater comfort; the support structure 1 uses, in said layer, padding materials, which would instead require subsequent processing steps so as to solve the problems of distribution and concentration typical thereof, makes it possible to maintain the main characteristics of said materials with significantly lower production costs, due to the simplification of the structure itself and, consequently, of its manufacturing process.

[0057] In the case of backrest and seat cushions covered with an outer cover in leather, eco-leather or similar materials, which has inner layers of padding used to provide greater comfort, quilted or even worse, filled with movable padding in chips, flakes, fibres and the like, not appropriately bonded, in the absence therefore of quilting, the support 1 makes it possible to eliminate the conventional drawback of the same of the cellulite and orange peel effect. Variations may be made to the invention described herein without departing from the scope of the inventive concept defined in the claims.

[0058] In said sphere all the details may be replaced with equivalent elements and the materials, shapes and dimensions may be as desired.
