SOURCES AND REMEDIES FOR RESTRAINT SYSTEM DISCOMFORT AND INCONVENIENCES
This study examines possible causes of failure of autombile occupants to wear restraint systems provided by the manufacturers. Attention is directed primarily to confusion, incovenience and discomfort factors in seat belt usage. Study phases consisted of: (a) literature survey to determine state-of-the-art in restraint system design and reasons why people avoid using seat belts; (b) preliminary user survey aimed at identifying in greater detail why people find seat belt systems inconvenient and uncomfortable; (c) new car survey to learn more about how current seat belt systems are designed and installed and if there are new developments that can improve the state-of-the-art; and (d) a series of laboratory studies designed to determine if it is possible to create a more suitable seat belt system. Based on laboratory results an optimized system was designed and tested in two vehicles. These optimized seat belt systems were then compared to four other 1974 vehicle systems to determine their acceptability by users from the standpoints of convenience and comfort. Results showed that the optimized system was significantly favored by test subjects.
