Cushioning member having a wavy outline

1. A cushioning member having a wavy conformation, comprising:

elastically deformable bands provided in a juxtaposed arrangement relative to each other according to a substantially longitudinal orientation, each of said bands having undulations which are inclined relative to a resting plane; and

joining strips between at least two of said bands and arranged roughly transversely relative to said bands,

wherein said bands are integral with said strips and are assigned a final and definitive shape, as required for use for which the cushioning member is intended, by virtue of the cushioning member being produced as a single-piece molding.

2. The cushioning member according to claim 1 , further comprising:

at least one zone exhibiting differentiated elasticity.

3. The cushioning member according to claim 2 , wherein said at least one zone exhibits differentiated elasticity by virtue of differing cross-sections

of said undulations.

4. The cushioning member according to claim 3 , wherein

at least one of said joining strips extends across an entire transversal extension of said bands so as to interconnect all of said bands.

5. The cushioning member according to claim 4 , wherein

at least one of said joining strips extends partially across a transversal extension of said bands so as to interconnect at least two of said bands.

6. The cushioning member according to claim 3 , wherein

at least one of said joining strips extends partially across a transversal extension of said bands so as to interconnect at least two of said bands.

7. The cushioning member according to claim 2 , wherein

said at least one zone includes at least one of said undulations, with said at least one of said undulations being reinforced by at least one fin, that is obtained integrally with production of the cushioning member, at a portion where said at least one of said undulations undergoes elastic deformation.

8. The cushioning member according to claim 7 , wherein

at least one of said joining strips extends across an entire transversal extension of said bands so as to interconnect all of said bands.

9. The cushioning member according to claim 8 , wherein

at least one of said joining strips extends partially across a transversal extension of said bands so as to interconnect at least two of said bands.

10. The cushioning member according to claim 7 , wherein

at least one of said joining strips extends partially across a transversal extension of said bands so as to interconnect at least two of said bands.

11. The cushioning member according to claim 2 , wherein

at least one of said joining strips extends across an entire transversal extension of said bands so as to interconnect all of said bands.

12. The cushioning member according to claim 11 , wherein

at least one of said joining strips extends partially across a transversal extension of said bands so as to interconnect at least two of said bands.

13. The cushioning member according to claim 2 , wherein

at least one of said joining strips extends partially across a transversal extension of said bands so as to interconnect at least two of said bands.

14. A footwear item having a sole comprising the cushioning member according to claim 2 ,

wherein said cushioning member is obtained directly in a shape of said sole by virtue of said cushioning member being produced as the single-piece molding, and

wherein said at least one zone exhibiting differentiated elasticity corresponds to a heel portion of the footwear item.

15. The cushioning member according to claim 1 , wherein

at least one of said joining strips extends across an entire transversal extension of said bands so as to interconnect all of said bands.

16. The cushioning member according to claim 15 , wherein

at least one of said joining strips extends partially across a transversal extension of said bands so as to interconnect at least two of said bands.

17. The cushioning member according to claim 16 , wherein

said joining strips are offset relative to one another.

18. The cushioning member according to claim 17 , further comprising:

a protective or covering layer.

19. The cushioning member according to claim 18 , wherein

said bands and said strips are formed by over-injection molding on said protective or covering layer.

20. The cushioning member according to claim 1 , wherein

at least one of said joining strips extends partially across a transversal extension of said bands so as to interconnect at least two of said bands.

21. A footwear item having a sole comprising the cushioning member according to claim 1 ,

wherein said cushioning member is obtained directly in a shape of said sole by virtue of said cushioning member being produced as the single-piece molding.

22. An insole insert comprising the cushioning member according to claim 1 , wherein

said cushioning member is obtained directly in a shape of the insole insert by virtue of said cushioning member being produced as the single-piece molding.

23. A seat for a two-wheeled or three-wheeled vehicle, comprising the cushioning member according to claim 1 ,

wherein said cushioning member is obtained essentially in a shape of the seat by virtue of said cushioning member being produced as the single-piece molding.

24. A protective member comprising the cushioning member according to claim 1 ,

wherein said cushioning member is obtained directly in a shape of the protective member by virtue of said cushioning member being produced as the single-piece molding.

25. A chair or seat including the cushioning member according to claim 1 ,

wherein said cushioning member is obtained directly in a shape of a component, of the chair or seat, adapted to support a part of a human body by virtue of said cushioning member being produced as the single-piece molding.

26. A mattress including the cushioning member according to claim 1 .

27. A pillow including the cushioning member according to claim 1 .

28. An inflatable mattress or pillow including the cushioning member according to claim 1 .
