2. The multifunctional seating system of claim 1, wherein interlocking between the crossbars and the cruises is made by reliefs suitable for making an elastic anchor engagement within corresponding holes located in the crossbars.

3. The multifunctional seating system of claim 1, wherein engagement between the soft blades and the protruding pins is performed by elastic tabs formed in the body of the cruises, provided with teeth with a harpooning undercut configured to engage in a corresponding recess obtained in the bottom of the soft blade.

4. The multifunctional seating system of claim 3, wherein the elastic tabs are configured to provide a release button consisting of an extension of the elastic tab symmetrically positioned with respect to the tooth to allow manual disengagement thereof.

5. The multifunctional seating system of claim 1, wherein the soft blades are made of composite material, or by advanced molding techniques with two different mix densities where a first density provides suitable softness to a seat and a second density provides sufficient resistance to the bottom of the soft blades.

6. The multifunctional seating system of claim 1, wherein the soft blades are made in composite mode, or by applying a molding casing shaped in conjugation to the bottom and consolidating it by a joint bonding.

7. The multifunctional seating system of claim 1, wherein joints between the cruises through their ends and the crossbars are partially decoupled by conferring one or two degrees of freedom to rotation of the zenith by setting up, during definition of pieces forming geometries, a controlled play of slight entity in the dovetail.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The invention is also illustrated purely by way of non-limiting example in the accompanying figures, wherein:

[0014] FIG. 1 shows a side view of an exemplary seating made according to the present invention, with partially sectioned backrest and support foot rear.

[0015] FIG. 2 shows three different measures of soft elements and the structural elements in a single overall axonometric view.

[0016] FIG. 3 shows a detail of the intersection between cross-shaped elements and crossbars, where the crossbars appear in longitudinal section.

DETAILED DESCRIPTION

[0017] With reference to the aforementioned figures, a seat 1 of an exemplary sofa configuration consists of a structural platform 2 on which a plurality of soft puff 3 is housed. The platform 2 is made up of a combination of crossbars 4 and cruises 5, and can be distanced from the ground by means of feet 6. The crossbars 4 are preferably produced with aluminum alloy extrusions having a profile conjugated with ends 7 of the cruises 5. The ends 7 are also provided with reliefs 7a for their elastic engagement within corresponding holes 4a provided in the crossbars 4.

[0018] Each crosspiece 5 is shaped so as to fit in close conjugation with a female cross-shaped bottoms 8 integral with the soft puff 3.

[0019] The platform 2 is therefore formed according to free measurements flanked by an appropriate number of crossbars 4 joined together by means of cruises 5. Above the platform 2 a plurality of cruciform supports (5) will thus be obtained, on which an equal number of finishing elements, for example soft blades 3, is fitted by means of their female cross-shaped bottoms 8.

[0020] The soft blades 3 are preferably made by injection molding of expansive rubber-like polymer mixes, able to give the desired degree of softness according to the type of seat. In the case of external realizations, the foams used must have a closed cell structure, i.e. without absorbing power.

[0021] The constructive geometry of the soft blades 3 is preferably of a parallelepiped type, in order to reduce the spaces between them when side by side. It is likewise possible to make soft blades 3a intended to rest on two or more crosses 5, in order to produce small overhangs or particular shapes.

[0022] In addition to the soft blades 3, the present invention provides for the possibility of accompanying the seat with different additional special elements, including support surfaces, backs, partitions, objects, arm rests, etc.

[0023] Soft blades 3 may also be made in composite mode, i.e. with advanced molding techniques with two or more different mix densities. The hardness of the base 8 is in fact decisive in conferring rigidity to the finished combination, i.e. solidity between the soft blades 3 or the special elements (9) and the bottoms 8. The bottoms 8 may be functionally replaced by monolithic blocks 10 to be glued to the soft blades 3. Likewise, the aesthetics of the lower part of the soft blades 3 can be harmonized by applying, again for general gluing, a molding casing 11 shaped in conjugation to the bottom 8.

[0024] The presence of the monolithic blocks 10, forming part of the present illustrative example, constitutes the solution which allows the maximum structural strength of the finished seat.

[0025] In order to avoid incidental unthreading of the bottoms 8 or of the monolithic blocks 10 from the cruises 5, it is envisaged to provide elastic tabs 12 provided with teeth 12a with a harrowing undercut profile; the teeth 12a are designed to embrace the crossbars 4 and to latch onto them thus preventing accidental removal of the soft blades 3.

[0026] Another equivalent solution, always suitable as the previous one to any circumstances that require an irreversible assembly, such as urban furnishings subject to public degradation, is to adopt bonding glues of suitable tenacity.

[0027] On the other hand, if the furnishings and seats are susceptible to subsequent modifications or partial removal of one or more soft blades 3 or other additional elements (9), the present invention envisages conforming the tabs 12 so as to provide a release grip 12b consisting of an extension of the tab 12 reachable manually.

[0028] The joints between the cruises 5 through their ends 7 and the crossbars 4 can be partially released by conferring one or two degrees of freedom to the zenith rotation (upward or downward rotation or both) in order to make platforms 2 able to flex slightly in concavity or convexity so as to satisfy particular aesthetic or ergonomic needs. If the special elements 9 have a considerable height such as, for example, the necessary height to form backrests (3a, FIG. 1), they may be implemented with reinforcing bars 13 embedded in said elements 9.

[0029] The cruises 5 also have a central hole 14 for receiving pins 15, possibly threaded, to support the feet 6.

[0030] The system of the present disclosure makes it possible to realize any complementary element 9, such as holders, arm rests, elements with orthopedic purposes, etc., keeping the lower functional part 5, 8, 10 constant of said element.
