| Abstract: | High frictional force between the skin and the air bag greatly influences the scratch damage to human skin when an air bag inflates and rubs against the skin. The coefficient of friction should therefore be reduced. In this study, we propose a new method to reduce frictional force by producing air lubrication between an air bag made of a non‐coated fabric and the human skin. Air was generated, and an experimental device that could measure frictional force was produced. The frictional force of the air bag with air was measured, and the effectiveness and efficiency were confirmed. In the presence of air, the friction disk materials, fabric materials, and fabric structure do not influence the frictional force and coefficient of friction. Instead, the coefficient of friction is influenced by air mass flow passing through the fabric. |
