Abstract—This project deals with the analysis of seat backrest of car. Computer aided design and finite element analysis are essential in order to predict accurately for the safety performance of automotive seat in an event of crash. In this work, finite element analysis is used to evaluate the strength, deflection and maximum stress characteristics of a reference automotive seat in an event of vehicle rear impact. The safety function is measured based on a backrest moment test in accordance with (ECE R-17) regulations and FMVSS 2O7 regulations which is particularly for rear impact. In first stage, the bending moment test of the reference seat backrest frame is done by using a complete model formed on CATIA V5R17 by integrating the major structural components including the connector, vertical side flange, top cross member and supporting plates and the maximum pressure to be apply on top cross member of the seat back frame of seat as per regulation of bending moment test. In order to confirm the strength requirements, bending moment deflection characteristics of the seat are studied in accordance with ECE R-17. In second stage, as per the regulation of FMVSS 207 for rear impact condition, the maximum pressure to be apply on the all part of the seat back frame including seat backrest and to evaluate the various stresses and deflection on various part of the seat backrest of seat. Further finite element analysis of seat backrest, on the basis of result obtained in stage second, the free- optimization is done to reduce the stresses and deformation on backrest.
