Abstract
Each restraint has advantages which would make it suited for the particular need of a particular consumer in a particular car, including cost savings, convenience, and weight saving capability. A restraint standard should recognize this diversity, and be written in such a manner that the manufacturer can equip the vehicle with a restraint suitable to the car and customer purchasing it. Passive interiors, passive belts, active belts, and air cushions all have particular advantages, and minimum safety standards should be written in such a form as to encourage further development of these systems, as well as new concepts.
