Road vehicles � Sled test method to enable the evaluation of side impact protection of child restraint systems � Essential parameters

Although accident analysis shows that side impact accidents continue to be dangerous for children in cars, the majority technical regulations of Child Restraint Systems (CRS) are focused on the crash performance under the frontal and rear impacts and do not include a side impact test, the main reason is that no good method to test side impact performance of CRS has been agreed on yet in the world. In this paper one side impact test method based on double sled concept is presented and realized. And several CRS models are tested; injury response values are measured from child dummy. It is observed that the sled buck concept is repeatable and able to distinguish preliminarily between CRS models.

Frontal sled test is an important platform that widely employed to predict and assess changes in overall safety performance as vehicle structural and occupant restraint parameters are varied. In this paper, a characteristic door intrusion velocity pulse in side impact was analyzed and a set of side test jig was designed, which realized one kind of simplified side impact sled test method. Then we compared the injury values of the side impact dummy, the result showed that there existed good correlation between sled test and full-vehicle test.

Child Restraint System

Side impact is the second most frequent collision compared with frontal impact, accounting for about 30% of the total number of accidents. Indicating from the statistics, there is at least one child among 10 people died in the accident. It is noticed that children have a higher risk of suffering serious and fatal injuries in side impact than in other impact directions. Therefore, it is great important to protect children in side impact. However, procedure to test side impact performance of child restraint system (CRS) has not been agreed on yet in the world. This paper focuses on analyzing the difference between NHTSA and ISO 29062 side impact test procedures. It will help us perfect our automobile safety standards system and constitute our relevant laws as a valued reference through researching lateral impact dynamic test of CRS in other advanced countries.
