Abstract

This study investigates the plastic suspension assembly which is installed on inside of vehicle seat and support passenger's back to supply the comfortable ride performance. It aims to develop the structural design in order to support driver's back uniformly and assemble seat back frame with plastic suspension effectively. The part of suspension is designed by considering the body pressure distribution of driver and it has the same size as the practical model on simulation analysis. It is confirmed that the analysis result of plastic suspension approaches the practical measured values and the better body pressure distribution can be obtained as compared with the existing wire type.

본 연구는 자동차용 시트 Back frame 내부에 설치하여 탑승자의 등부분을 지지하며 편안한 승차감을 제공하는 시트용 서스펜션 시스템에 대한 연구이다. 운전자의 등 전체를 고르게 지지하는 구조로 설계하고 시트 백 프레임과 플라스틱 서스펜션의 조립을 효과적으로 할 수 있는 구조로 개발 하고자 한다. 서스펜션 단품은 운전자의 체압 분포를 고려하여 설계하고 시뮬레이션 해석에 있어서는 실제 모델과 같은 크기를 가지고 하였다. 플라스틱 서스펜션의 해석결과가 실제 측정값에 근접함을 확인하였으며 기존 Wire Type에 비해 양호한 체압분포를 얻을 수 있었다.
