Abstract
The invention uses a pair of curved opposed diagonal bars between the wad and cup. The bars (deformable resistance members) buckle in the radial direction and end up basically flat between the wad and cup to give surprisingly and unexpectedly high amounts of collapse (80% or more). This allows the space between wad and cup to be decreased significantly without sacrificing cushioning.
