ENERGY ABSORBING CELLULAR MATRIX FOR VEHICLES WITH PLURAL WORKING ZONES Abstract of the Disclosure Soft face bumper for vehicles incorporating a resil- ient energy absorbing cellular matrix molded from plastic material in which the walls of longitudinally extending cells taper from minimum thicknesses at opposite ends thereof to a maximum thickness at a parting line intermediate the ends. With double tapered walls, each cell has at least two sepa- rate working zones which preferably deflect simultaneously to optimize energy absorption. With draft angle of the cell walls effectively reduced by this construction a savings in weight, material and molding cycle time is provided.
