Back disorders in trock drivers are a direct result of the poor quality of vehicle seats and suspension systems. A new type of seating system designed by a private company may help prevent back disorders in truck drivers. The system uses inflatable air-bags to provide support and suspension, and appears to avoid the pitfalls, noted by ergonomists and designers in previous attempts in this direction. Prototypes were produced and their compliance with Canadian automobile safety regulations, the U.S.A.’s National Highway Traffic Safety Administration (Department of Transport) regulations, and accepted principles of mechanical and industrial engineering, ergonomics and design. Marketing factors were also studied. In specific, the prototypes’ ability to reduce vibration to levels recommended by ISO 2631 was tested in trials on Québec roads and in laboratory simulations using an electromagnetic vibrator. The results of the computer simulations and the field trials indicated the need for further product development.
