A bumper for a vehicle is disclosed. The bumper includes a housing that has a pair of interlocking supporting frames. One of the supporting frames is fixed to the vehicle body. The bumper includes a plurality of rebounding elements and a plurality of biasing elements, each that are fixed within one of the supporting frames of the housing. Each of the rebounding elements has a predetermined rebounding elements spring coefficient. The plurality of biasing elements has a biasing elements spring coefficient that is not equal to, and is preferably less than, the spring coefficient of each rebounding element. Further, each of the biasing elements abuts one of the rebounding elements. As such, as the interlocking supporting frames of the housing are compressed in a vehicle collision, the plurality of rebounding elements together with the plurality of biasing elements absorb the collision energy and are each compressed at different rates.
