SHOCK ABSORBING BUFFER ASSEMBLY Abstract of the Disclosure: This buffer assembly forms a shock absorbing system that has a rigid horizontally-extending channeled support beam disposed in the vehicle body which is coupled to the vehicle frame. An elongated one-piece plastic grid of longitudinally extending cells provides a resilient primary energy-absorbing medium which is seated in the support beam and which extends forwardly to an exterior location with respect to the vehicle body for absorbing impact forces. A central portion of the plastic grid provides a yieldable backing for a centralized rubber-covered metal plate that distributes localized impact forces to a large number of cells of the grid to reduce impact penetration. A thin walled flexible plastic facia, fitted over the spreader plate and over horizontally extending wing portions of the cellular grid, is peripherally fastened to the vehicle body to provide a streamlined appearance and to simulate vehicle body work.
