Abstract
This paper aims to analyze how child restraint systems (CRS) in cars should be positioned to protect children at the ages 1 to 5. The study is preformed in co-operation with the Swedish insurance company Folksam. Data from Folksam´s database on car crashes in the years 1999-2004 is being used in this study. Every child in the ages 1 to 5 was searched for in the database, which resulted in 184 observations. To perform the analysis, categorical data analysis is suitable. The model used, is logistic regression. The model consists of three dichotomous variables; the explanatory variables being Type of CRS (rearward or forward) and Direction of collision (one direction affecting driver and child equally, or one direction affecting them...

This paper aims to analyze how child restraint systems (CRS) in cars should be positioned to protect children at the ages 1 to 5. The study is preformed in co-operation with the Swedish insurance company Folksam. Data from Folksam´s database on car crashes in the years 1999-2004 is being used in this study. Every child in the ages 1 to 5 was searched for in the database, which resulted in 184 observations. To perform the analysis, categorical data analysis is suitable. The model used, is logistic regression. The model consists of three dichotomous variables; the explanatory variables being Type of CRS (rearward or forward) and Direction of collision (one direction affecting driver and child equally, or one direction affecting them differently). The response variable is Relative injury (the child was less injured than the driver or the child was equally or more injured than the driver). Putting the child’s injury in comparison to the injury of the driver enables comparisons between different children, even though circumstances vary from case to case. It turns out that both the explanatory variables have significant impact on the Relative injury of the child. Children positioned in rearward facing CRS are less injured in comparison to their drivers than children positioned in forward facing CRS. Consequently, it can be recommended that children between 1 and 5 should be put in a rearward facing CRS when seated in cars. (Less)
