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.

Abstract:
A structural body of a vehicle can comprises: a hollow metal component comprising walls that define a channel, wherein the metal component has a metal component length, and wherein the metal component is selected from the group consisting of beam, rail, pillar, chassis, floor rocker, and cross-bar, combinations comprising at least one of the foregoing; and a plastic-metal hybrid reinforcement having a cavities therethrough, and a metal support having greater than or equal to 3 walls forming a support channel. The plastic element is located in the support channel wherein the reinforcement is located in the component channel.
