Influence of Various Types of Office Desk Chair for Dynamizing the Operation Assessed by Raster Stereography

Abstract

The current development trend of the operational activities indicates an increase in occupations which last for a few generations and whose primary position is the activity in the sitting position. This trend is directly connected with the technological progress and development of the society within Industry 4.0. However, the workplaces intended for sitting occupations that are designed according to the current standards are unsuitable from several perspectives. The long-term sitting activities at most actual workplaces cause an accumulation of the static load. For this reason, the article deals with dynamizing the activities in the sitting position. The presented research is based on utilizing the knowledge of the sitting posture dynamics and on the information acquired through diagnostics based on the Raster Stereography as an innovative method based on modelling a natural human spin. The article brings the first research results, which points out the fact that probably not all types of dynamic sitting that are nowadays preferred are suitable for long-term working.
