Abstract (en)
[origin: EP2929813A1] The present utility model refers to a layer (1) for the formation of a mattress. The layer foresees a plurality of incisions (10) passing through its entire thickness and arranged in succession one after the other along the direction of development of the incision and at intervals between them of a distance (dx) in such a way as to form at least a line (20, 30) of incisions, preferably two or more lines of incisions parallel between them and spaced between them of a pitch (dy). In such a manner, in correspondence of the application of a traction (T) to the layer (1) substantially orthogonal to said line (20, 30) of incisions, the incisions open to form, each one, a passing opening. Each incision has, besides, a pre-determined length (L). In accordance with the invention, the length (L) of each incision is comprised within a range between 8 cm and 20 cm, preferably between 10 cm and 20 cm and better still between 15 cm and 20 cm, for example 18 cm, the distance (dx) being comprised within a range between 4 cm and 10 cm, preferably between 5 cm and 8 cm, for example 6 cm.
