Abstract

An energy absorbing countermeasure for motor vehicle doors comprises a body having at least a first zone and a second zone. Each zone has at least one surface with recesses in the surface and portions between recesses. The portions are broken upon impact and enter into the recess to exhibit energy absorbing efficiency. The recesses in the first zone are arranged or configured to absorb a first desired peak load during impact and the recesses in the second zone are arranged or configured to absorb a second desired peak load during impact. The first desired peak load is different from the second desired peak load.
