摘要：An energy absorbing structure including an injection molded base plate (24) hasa plurality of hollow cylindrical tubes (26) formed integrally therewith and projectinggenerally normal therefrom in spaced relation from each other. Each cylindrical tube (26)has a base integrally molded with the base plate (24) and a distal end spaced from the

base so that the tube obtains a preselected length which collapses under load to absorbenergy. The tubes preferably have a greater wall thickness at the base than at the distalend and the wall thickness preferably tapers uniformly from the greater thickness at thebase to the thinner thickness at the distal end. The tubes may be interconnected at thebase by a web structure (32,34) integrally molded between the base wall and the tubesto stiffen the tubes against bending. The energy absorbing characteristics of thestructure can be varied in a preselected manner by varying the length of the tubes, thenumber of the tubes, the spacing of the tubes, the thickness of the tubes and the plasticmaterial used to mold the tubes.
