Abstract
This paper presents an objective method to evaluate the emotional feeling of the pulling force of a seat belt. Physical quantification is required to objectively evaluate the emotional feeling of the pulling force. This quantification is called the “Force metric.” The force metric is correlated with the subjective rating of the pulling force. In this paper, the force metric is extracted from the pulling force measured by using a specific robot. A subjective evaluation is performed on the pulling force of the seat belt of 18 vehicles. A pulling force index is developed by the linear regression of the force metric and subjective rating. The pulling force index is used for the objective evaluation of the emotional feeling of the pulling force of a seat belt throughout the modification of seat belt components.
