ABSTRACT:
An energy absorbing bumper system for protection of moving vehicles. The system comprises a flexible section and a rigid section, each containing compressed air, and an orifice passage or valve for controlling the flow of air between the flexible section and the rigid section. The flexible section is contoured for a generally flat impact surface to provide efficient operation and compact size, and to yield an aesthetically pleasing shape, and is held in shape by dividing the flexible section or bag into a large number of compartments lying adjacent to each other along the direction of the surface to be protected, and by introducing compressed air into each compartment. Each one of the compartments of the bag is connected to the rigid section by means of an orifice, or by a relief valve.
