THE PRODUCTION HELP BUMPER: EVOLUTION, TESTING AND EVALUATION

A High Energy Level Pneumatic (HELP) bumper system, designed to fit all transit coaches presently made by prime bus manufacturers is presented. It is adaptable for retrofit to older coaches. Vehicle tests have demonstrated 6 mph barrier crash capability and 10 mph collisions into pre-1973 passenger cars with no damage to bus or HELP bumper. Collisions with a 1974 passenger car at speeds to 8.5 mph resulted in no damage to either vehicle.
