Abstract
In one embodiment, a rail extension comprises: an energy absorber comprising a polymer body, and vehicle attachment tabs extending from one end of the energy absorber and configured to attach to a vehicle rail, and an attachment tab extending from another end of the energy absorber and configured to attach to a bumper beam. The energy absorber can comprise cells formed by cell walls extending a length of the energy absorber and forming cavities therethrough; and open channels formed on each side of the energy absorber, wherein the channels are defined by walls of adjacent cells. A vehicle can comprise: a bumper beam; a vehicle rail; and the rail extensions.
