Stock Car Racing Driver Restraint – Development and Implementation of Seat Performance Specification

Over the last decade large safety improvements have been made in crash protection for stock car racing drivers. It has been well established that in side and rear impacts the driver seat provides the primary source for occupant retention and restraint. With the implementation of NASCAR ® 's (National Association for Stock Car Auto Racing, Inc) newest generation of stock car, the Car of Tomorrow (COT), into the racing schedule, the opportunity to develop and implement a universal stock car driver seat performance specification was accomplished. This paper describes the development of the Seat Performance Specification including the goals of the specification, the methodology used to develop it, a census of the existing driver seat population used in on-track competition, review of developmental dynamic specification sled tests and quasi-static tests as well as summation of the Seat Performance Specification requirements.Cross Reference:
