This information report encompasses the significant factors which determine the effectiveness of the total occupant restraint system in all commonly encountered collision configurations. The total system includes all components which affect occupant injury by influencing the manner in which the collision energy exchange is performed. In addition to the elements that contribute to impact attenuation@ consideration must be given to factors that encourage maximum use@ such as comfort@ reliability@ appearance@ and convenience. Hence@ system evaluation necessarily involves consideration of the complete vehicle. PURPOSE - The purpose of this SAE Information Report is to facilitate the development of restraint systems used in passenger cars to minimize occupant injury during collisions by: (a) standardizing restraint system testing methods so that results from various facilities can be compared. (b) serving as a guide in the design and development of effective restraint systems and in the preparation of detailed procedures for testing and evaluating specific types of restraint systems. (c) providing an orientation for research in human tolerance to impact and for the development of improved human simulators. The evaluation procedures discussed are lacking in some details at this time due to limitations in such areas as measurement systems@ collision simulation@ and data on human tolerance to impact; they will necessarily be subject to continuing review and improvement. Nevertheless@ they are intended to form the basis for overall evaluation of any means by which a collision energy exchange between an occupant and his vehicle can be accomplished. Where present knowledge does not allow sound procedures and rigorous specifications consistent with this broad outlook@ an attempt has been made to avoid arbitrary or restrictive statements. At the present state-of-the-art@ judgment and experience must provide major guidance in restraint system testing.
