The Influence of Personal Motor Vehicle Design on Injury to Passengers During Traffic Accidents
Published January 01, 1972 by Institution of Mechanical Engineers in United Kingdom
A 1969 investigation of personal motor vehicle accidents was conducted on the basis of insurance reports. Of 45,000 accidents reported, 10,271 were incorporated into the report. Five comparison categories were used: vehicle type, persons involved, accident type, collision speed, and seating position in vehicle. Car damage was rated on a 1-5 scale, personal injury on a 1-7 scale. Injuries were designated by type and extent, head, knee, and neck being the worst. Design improvements are drawn from the report.
Injuries were worst and most frequent for front seat persons. Pictures relate types of injury to position in car. Paper concentrates on improvements other than well-known ones such as seat belts, head-rests, and air-bags, although these are discussed. Improvements include more sharply angled windshields, laminated glass for windows, the positioning of the dashboard, and knee-protection cushioning. Safety requirements for driver and front-seat passengers are compared. Many examples of current dashboard protection have not proven their effectiveness.
Difficulties are encountered in implementing fundamental design changes. It is recommended that changes be implemented as soon as possible.
