- Published : 2000.11.02
Abstract
All chairs are uncomfortable in the long run, but some chairs become uncomfortable more rapidly than others, and in any particular chair, some people will be more uncomfortable than others. Comfort will depend upon the interaction of chair characteristics, user characteristics, and task characteristics. In this study, we intend to design the comfortable office chair by investigating the anthropometric and biomechanical aspects for Korean. Therefore, we determine the design dimensions using the analysis of anthropometric data. With these dimensions, we design the chair mechanism of which backrest reclines with increasing chair pan declination. This mechanism allows the back to get adequate support at the correct level for any backrest declination. Also, the lumbar support in the backrest descends with increasing backrest reclining. By using this chair, a considerably better sitting posture can be obtained, and uncomfortable feeling and back pain may be prevented.
