1. A compressible cell for attenuating impact forces imparted thereto in three stages, the cell comprising:

  • a hollow enclosure comprising(a) a top wall having (i) a raised central portion and (ii) at least one corrugation around a periphery of the raised central portion,(b) a bottom wall, and(c) a side wall extending between the top and bottom walls, the at least one corrugation descending to a depth below half a height of the side wall,whereby impact forces imparted on the cell are attenuated in a first stage by resistive yielding of part of the at least one corrugation to allow for depression of the central portion, in a second stage by resistive yielding of the side wall, and in a third stage, upon contact of the at least one corrugation with the bottom wall, by resistive yielding of the at least one corrugation.
