Effects of vehicle features on CRS installation errors
This report documents a study of how vehicle features contribute to CRS installation errors. Thirty-two subjects were recruited based on their education level (low or high) and experience with installing CRS (none or experienced). Each subject was asked to perform four child restraint installations...
Labels, instructions and features of convertible Child Restraint Systems (CRS) evaluating their effects on CRS installation errors.
This report documents a study of how CRS features, labels, and instructions contribute to CRS installation errors. Task 1A focused on assessing different physical features of 16 convertible CRS, while Task 1B evaluated baseline and modified versions of labels and instructions for two CRS models....
Driver report of improper seat belt position among 4- to 9-year-old children
OBJECTIVE: To determine the frequency with which drivers report improper seat belt positions among children 4-9 years of age and the frequency with which reported problems were attributable to the lap belt, shoulder belt, or both. SUBJECTS AND METHODS: Analysis of driver responses to 5 questions...
LATCH usability in vehicles
This project investigated the usability of Lower Anchors and Tethers for CHildren (LATCH) hardware by measuring LATCH implementations in 98 2011 or 2010 model-year vehicles. ISO and SAE LATCH usability rating systems were used to assess all vehicles using data from the second row left position....
Vehicle LATCH system features associated with correct child restraint installations
Objective: Lower Anchors and Tethers for Children (LATCH) was intended to standardize the attachment between child restraints and vehicle seats. However, LATCH implementations vary, resulting in different ease-of-attachment of child restraint connectors. Identifying vehicle characteristics...
Effects of vehicle seat and belt geometry on belt fit for children with and without belt positioning booster seats
A laboratory study was conducted to quantify the effects of belt-positioning boosters on lap and shoulder belt fit. Postures and belt fit were measured for forty-four boys and girls ages 5–12 in four highback boosters, one backless booster, and on a vehicle seat without a booster. Belt anchorage...
Effects of vehicle seat and belt geometry on belt fit for children with and without belt positioning booster seats.
A laboratory study was conducted to quantify the effects of belt-positioning boosters on lap and shoulder belt fit. Postures and belt fit were measured for forty-four boys and girls ages 5–12 in four highback boosters, one backless booster, and on a vehicle seat without a booster. Belt anchorage...
Child passenger restraints in relation to other second-row passengers : an analysis of the 2007-2009 National Survey of the Use of Booster Seats.
Objective: Child restraint systems (CRS) are increasingly being designed to accommodate larger children and to mitigate side impact injuries. Little is known about the impact of CRS on the safety of other vehicle passengers due to limitations of existing crash databases. This study provides the...
