Ambulance patients are subjected to high vibration levels because of the lack of coordination of damping characteristics of vehicle and stretcher in modern ambulances. A parameter study optimized the dynamic characteristics of the stretcher support in relation to the vehicle by drawing on data of a previous investigation. By these means a new stretcher support was designed and constructed. The following features were incorporated:- vibrational characteristics tuned to vehicle suspension, regardless of loading- feet-first positioning of patient in driving direction- arbitrary height level of patient- vibrational characteristics independent of position- free space under stretcher- ease of loading and unloading- attachment of mechanical components (stretcher guidance and vibration-damping systems) to driver cab wallDriving tests with a prototype model showed that the driving comfort values which were computer optimized were indeed realized. As noted, vibrational-characteristics were also greatly improved.
