Abstract
An energy-absorbing system includes a tube made of a continuous polymeric material. The tube has first and second tube sections connected by an intermediate tube section. By this arrangement, upon the bumper system receiving a longitudinal impact, the first and second tube sections telescopingly collapse with a predictable and consistent rolling collapse.
