Samenvatting
The value of the three point safety belt has been evaluated by a statistical analysis of more than 28.000 accident cases. The safety harness concerned is the Volvo three-point combined lap and upper torso harness with a so called slip-joint. The average injury-reducing effect of the harness proved to vary between 40% and 90% depending on the speed at which the accident occurred or the type of injury. The frequency of use increased with age of the occupants.
