This paper introduce an analytic method to estimate the proper space and stiffness of the vehicle's pillar trim to meet FMVSS 201 head injury criteria. A practical guideline curve, which is used in determining the adequate space and stiffness of pillar trim, is derived assuming haversine function for the head impact pulse. Rib structure of pillar trim, which has a required stiffness, is designed by the case study using finite element analysis. The analytic method showed good correlated results compared with the test results.
