This report discusses the development of a standard bench seat for the testing of child restraint systems based on the configuration and performance parameters of the 1974 Chevrolet Impala production bench seat. Both static and dynamic characteristics of the production seat were modeled into the frame deformation and foam stiffness of the standard seat, and impact sled tests were conducted on each using a representative sample of child restraint systems to provide direct comparison between the two seats. The standard seat was shown to be a durable, repeatable test platform for child restraints that provided reasonable simulation of the production seat. Its economic breakeven point occurs when more than four new production bench seats are required for testing. Child restraint tests on the standard seat tend to give slightly lower head and chest peak resultant acceleration, HIC and Severity Index values and, in some cases larger head excursion values than comparable tests with the production seat. /HSRI/
