Abstract
The importance of comfort is increasing, both socially and economically. Especially professional drivers often have comfort-related physical complaints., such as lower back pain. Literature shows relations of the personal subjective feeling of comfort with vibrations and pressure distributions. In addition, car manufacturers can use comfort to distinguish their cars from their competitors. However, the development and design of a new, more comfortable car seat is very time consuming and costly. The use of computer models of human and seat could facilitate this process. MADYMO human and seat models offer the possibilities of the multibody 50th percentile human model for vertical vibrations. Further, the inclusion of a finite element pelvis is described, allowing the model to predict pressure distributions. Preliminary results of a static pressure validation are presented.
