A bumper having crash-boxes accommodated at least in part by space in a hollow cross beam section. As a result, when impact due to collision occurs, deformation of the crash-box takes place early, so that for the same outer dimensions of the bumper longer crash-boxes can be employed. This is of advantage as the energy absorbed by the compression of the cross beam is small in relation to the mass employed and the distance traversed compared with the that achieved with crash-boxes. The capacity to absorb energy exhibited by the proposed bumper is therefore greater than that achieved by conventional bumpers.
