Usage of Adult Belts in Conjunction with Child Safety Systems as a Means to Optimize Convenience

The paper describes the positive effect on the convenience of child safety systems by using adult seat belts. It shows how manufacturers of child safety systems in West Germany have gradually switched from supplying specially fitted belt systems to using rear seat adult seat belts.

On the basis of accident reports collected over a period of 10 years, the overall performance of an impact shield design, which is using adult seat belts, is investigated and asked, whether additional ease of use or convenience compromises safety.

Among other parameters, the head excursion criteria of the specific impact shield system is highlighted. Finally, dynamic sled testing, simulating the effect of additional belt slack and various lower anchor point locations is described.
