A new integrated child safety seat is presented in this paper. The seat is a two-mode seat for a motor vehicle cooperable with an adult seat belt assembly to provide two modes operation including an adult seat mode and a child seat mode. The seat locates in the center of the rear seat. The structure of the seat was designed in detail. The height of the booster of the seat can be adjusted continuously according to the seated shoulder height of the child passenger. The depth of booster cushion also can be changed according to the size of the passenger. The sled test with the seat was conducted. The seat simulation models with different booster heights were developed using MADYMO software and validated. Then, these models were used to study the performance of the seat in frontal impact. Some key parameters of the seat were studied in simulation test. The results of the test and simulation show that the seat can provide effective protection for the children aged from 3 to 10 years in frontal impact.

Systematic observations of 231 children (infancy to 5 years) and the 231 adults accompanying them were made in 29 supermarkets in Edmonton, Alberta, Canada. The objective of the study was to describe the influence of two indices of adult supervision in supermarkets on children's activities in shopping carts. Adult supervision was measured by whether the adult ever lost sight of the child and whether the adult was 10 feet or more from the child at any time during a shopping trip. 23% of the children stood on the ends or sides of carts; 49% climbed or tried to climb out of carts. Adults lost sight of a child, whether in or outside the cart, a mean of 3.3 times and were 10 feet away 2.7 times during an average shopping trip. Logistic regression showed that a child rather than an adult pushing a shopping cart through the store was the strongest factor related to standing on ends or sides of carts. Pushing by a child was more likely to occur when adult monitoring was low and when children were older. Climbing out was predicted by the number of times an adult was > 10 feet away, older children, and a child being in the cart basket as opposed to outside the cart or in the child safety seat.

Objective. To determine if hands-on instruction in child safety seat (CSS) installation decreases the number of errors in installation. Design. Cross-sectional study. Setting. Primary care offices, emergency department, CSS checkpoint. Participants. Parents of children <2 years old receiving medical care or attending a CSS check. Main Outcome Measure. Errors in CSS use. Results. Only 6.4% of parents had a correctly installed CSS. Hands-on instruction was associated with fewer errors in seat installation. Increased parent age, completion of college, and having private insurance were also associated with fewer errors in CSS placement. The majority of parents learned to install seats from reading the manual, from friends and relatives, and from figuring it out on their own. Conclusions. Errors in CSS installation are a significant problem. Hands-on instruction decreases the numbers of errors in CSS installation. However, few parents receive hands-on instruction from experts in CSS installation. Increases in correct CSS use could result from hands-on education by trained professionals.
