Abstract
A system constituted of a retractable bumper coupled with a hydraulic shock absorber the shock absorption characteristic of which is governed by a pressurized gas, a weight sensor for sensing the vehicle gross weight, a pressure regulator for the pressurized gas, a carriage mechanism which supports the shock absorber and can move it in the longitudinal direction of the vehicle, and an electrical control unit for controlling both the pressure regulator and the carriage mechanism in response to the signal from the weight sensor, so that the energy absorption capacity of the system in a collision of the vehicle represented by the product of the resistance offered against a retracting movement of the bumper by the shock absorber and the distance travelled by the bumper until coming into contact with the vehicle body can be varied depending on the weight of the vehicle payload.
