Abstract
Abstract A compression-type cushioning pad provides load-travel characteristics to meet specific shock cushioning requirements. The pad comprises a metal plate having a cushion of elastomer bonded to at least one side thereof, the cushion having a corrugated surface configuration contoured to provide the desired load-deflection characteristics.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
148 words
A compression-type cushioning pad comprising a plate member having an elastomeric cushion bonded to a side of said member, said cushion having alernate ridges and valleys extending across the pad, each of said ridges being of maximum cross-sectional area at its midpoint and the opposing sides of said ridges diverging from their midpoint to the outer ends of the ridges, the opposing sides of said ridges being so contoured that upon the application of a predetermined compressive load to said pad, the opposing side of said ridges flow towards each other in such a manner that filling of said valleys occurs at the bottom thereof at point midway between the longitudinal ends thereof and said filling continuing until the opposing sides of said ridges come into contact at the midpoint thereof and under increasing compressive load engagement between said opposing sides progresses toward the ends of said ridges.
