Abstract and keywords

An increased number of technological interfaces with the customers such as rear‐seat‐ entertainment displays increase the weight that has to be carried by the front seat. Understanding and quantification of the influence of seat‐design parameters in a rear‐end impact enable design engineers to develop seats fulfilling requirements of test procedures with the aim to reduce the risk of an injury. The research objective is to verify the causality of influencing seat‐design parameters of a seat identified by the use of multivariate‐analysis‐methods by reference to a front seat. The kinematic behavior of three seat‐design parameters foam thickness and kx distance between the head restraint and the upper cross member of the seat‐ back were analyzed. It was shown that the results of multivariate‐analysis‐methods for the looked at seat‐design parameters give a valid prediction of the influence on the kinematic behavior of a BioRID‐II anthropometric test device due to a change in a seat‐design parameter. It was concluded that these results help design engineers in an early stage of the development to improve the seat‐design to reduce the risk of sustaining a whiplash associated disorder.
