The recent past shows enormous efforts of some CRS-manufacturers to improve the protective properties of Child Restraint Systems (CRS). Several tests performed by different associations forced these manufacturers to improve the safety qualities of their products. In addition, activities, like the ISOFIX working group, help to increase the child safety in the future. Examining the car manufacturer activities in passive safety, the development is only partially considering the child safety. At least two trends of upcoming small and micro cars may cause negative effects: lack of space in the rear compartment; higher deceleration pulse due to increasing car stiffness. These trends seem to be contradictory to the general requirements given in Figure 1. Regarding the actual ECE-regulation, it is obvious that commonly certified and used CRS are not designed for those changed requirements. This paper contains the analysis of both these effects on the child and the investigation of three different, actually discussed, CTS attachments. (A)
