초록

폴리우레탄 발포체는 쿠션성이 뛰어나기 때문에 자동차 시트 쿠션으로 다양하게 사용이 되고 있다. 그 동안 시트 쿠션 발포체의 연구에 있서서 발포체 밀도를 낮추고자 하는 요구가 있어 왔으나, 최근에는 승차 안락감을 증대시키는 것이 더욱 중요시되고 있다. 승차 안락감과 관련하여 본 연구에서는 반발 탄성률 특성 및 히스테리시스 특성과 같은 정적물성을 조절하는 것에 관하여 연구하였다. 또한 승차 운전시 안락감 성능에 영향을 주는 매우 중요한 인자로 알려져 있는 진동 특성에 관하여 고찰하였다.

Polyurethane flexible foams have been widely used for automotive seat cushions because of their excellent performance. It has been required so far to reduce the density of seat cushion foam. However, recently, improving the riding comfort of seat cushions becomes more important. With regard to riding comfort, we investigated the improvement of static properties such as the ball rebound property and the hysteresis loss. We also studied the vibration characteristics, which are well known as an important factor to affect the comfort performance during driving.
