Abstract
Advanced integrated modeling and simulation are becoming increasingly popular in developing different individual components, ranging from main structural frames to restraint systems, in order to enhance the value of design. The objective of this research was to study the strength required of an advanced structurally integrated belt-seat restraint system that meets the current FMVSS requirements. Conceptualization, detailed design development and evaluation were carried out with the help of detailed finite element models and subsequently verified through a number of experiments. A method of designing the lower portion of the rail structure below the recliner and the back frame above the reclining device was developed to reduce the total design cycle time for a complete seat structure by minimizing the computational time through a cost-effective substructuring approach.
