Foam material - pad with a single-phase compression behavior

摘要

Padding, which a homogeneous cushion layer consisting of open-cell foam material, which in the unloaded state in the direction of loading has the height h and in which at each point 0 ≦ x ≦ h the cross-sectional area of the padding layer (f)_x and the pressure voltage value cv₄₀ the padding layer (s)_x , characterized in that the product (p)_x = (F)_x·(S)_x between the imaginary value x = h and the value x = 0 changes linearly with x, i.e. (P)x = (F)x·(S)x = a · (h, x)with the two limiting cases (P)x = h = 0 or small in relation to a · hand (P)x = 0 = a · hwherein a is a constant.
