Comparative Analysis of Child Restraint Systems Safety Parameters in Relation to the New Regulation No. 129 of the Economic Commission for Europe of the United Nations (UN/ECE)

This study presents a comparison of the common Child Restraint Systems (CRS) which reduces the value of dynamic loads affecting the child’s body during car accidents. The analyzed systems were: child seats, booster seats, and straps—adjustable vehicle seat belts adapted to children’s stature. The effectiveness of the analyzed devices was assessed on the basis of experimental tests carried out in the accredited laboratory approving the Child Restraint Systems. The tests were carried out in accordance with the new Regulation No. 129 UN/ECE. The authors examined whether the tested devices meet the guidelines of the new Regulations No. 129 despite approval in accordance with Regulation No. 44. Based on the research results, better safety parameters of some new solutions dedicated to children’s safety could be observed. Almost all the selected CRS met requirements stated in Regulation No. 129. The only exception was for abdominal pressure in one of the tested devices. Head Resultant Acceleration in tested devices was 14.7–39.0% less than the limit determined in Regulation No. 129 whereas Chest Resultant Acceleration was 17.4–37.6% less. Abdominal pressure was 46.4–81.4% beneath the limit (apart from one case which did not meet the requirements). The HPC parameter (Head Performance Criterion) was 45.4–74.5% less. The final results show that there are still some possibilities for improving the safety of young vehicle passengers.

The study presents a comparison of the common Child Restraint Systems (CRS) which reduces the value of dynamic loads affecting the child's body during car accidents. The analyzed systems were: child seats, Combi Booster Seats, and straps adjusting vehicle seat belts to children's sizes. The effectiveness of the analyzed devices was assessed on the basis of experimental tests carried out in the accredited laboratory approving the Child Restraint Systems. The tests were carried out accordingly to the new Regulation No. 129 UN / ECE. Whether the tested devices meet the guidelines of the new Regulations No. 129 despite approval in accordance with Regulation No. 44. Based on the research result, better safety parameters of some new solutions dedicated to children’s safety could be observed. The final results show that there is still space for improving the safety of young vehicle passengers.

A Comprehensive Review on the Development of Car Booster Seats for Children

Over the past decade there has been a deeply troubling increase in the number of vehicle traffic fatalities involving children. Owing to this, many researchers have contributed to research and development on car booster seats for children. In view of this, the current work encompasses a compilation of articles reviewed on car booster seats for children ranging from the years 1988 to 2018. Further than that, this work also provides information relating to the varying designs and specifications of car booster seats. Concurrently, the writers also propose potential future research that could be undertaken in relation to the developments in child car booster seats, which in turn may allow for new research pathways in this area of interest. Finally, taking into consideration the design and safety factors of the current market trend car booster seats for children, the writers also propose possible state of the art car booster seats for various applications.

Situational Use of Child Restraint Systems and Carpooling Behaviors in Parents and Caregivers

Suboptimal compliance with child restraint system (CRS) recommendations can increase risk for injury or death in a motor vehicle crash. The purpose of this study was to examine scenarios associated with incomplete CRS use and non-use in children ages 4–10 years. We used a cross-sectional online survey with a convenience sample of parent/caregivers from the United States, age ≥18 years, with a child age 4–10 years in their home, who could read and spoke English, and drove child ≥6 times in previous three months. We used descriptive statistics and Mann-Whitney U to describe and compare the distribution of responses to situational use of CRSs among car seat users and booster seat users. We also used descriptive statistics and the Mann-Whitney U to describe and compare the distribution of responses to carpooling items among booster seat users and non-booster seat users. There were significant differences among those who reported most often using booster seats (n = 282) and car seats (n = 127) in situations involving rental cars, driving just around the corner, car too crowded to fit the CRS, not enough CRSs in the vehicle, the CRS is missing from the car, or the child is in someone else’s car without a CRS (p < 0.05). Among those who reported most often using booster seats and who carpooled other children (n = 159), 71.7% (n = 114) always used a booster seat for their own child. When carpooling other children, booster seat users were significantly more likely to use booster seats for other children ages 4–10 than the non-booster seat users (p < 0.01). Continued education and programs surrounding CRS use is critical, particularly for children who should be in booster seats.
