An impact absorbing bumper apparatus for motor vehicles in which the bumper is supported on telescoping legs extending from the vehicle, the legs retracting in response to the application of an impact load to the bumper. The retracting movement of the legs is resisted by an energy absorbing means comprising a replaceable cartridge made of a crushable material. A shiftable plate assembly is positioned in the legs. After impact forces have crushed the cartridge, the legs are disassembled to provide access to the shiftable plate assembly for removal of the crushed cartridge and replacement with a new cartridge.
