Study on Pressure and Movement Restriction of Stab-resistant Vests
In this study,factors for movement restriction of stab-resistant vests were investigated.The contact area and pressure between the vest and a dummy were measured,and sensory tests were performed for movement restriction in the wearers upper body.We used four vests of different sizes,weight and types of stab-proof material.The pressure distribution of the vests on a dummy was measured and cross-sections of dummy-worn vests were obtained by 3D scan.For these measurements,we controlled the tightness value,the ratio between vest waist circumference and dummy.In order to check the influence of vests on the movement of upper body,a sensory test for the movement restriction of jackets was confirmed.We discovered that vests tend to hang on the neck point,shoulder,chest and back.The pressure on the chest increased with increasing tightness value,while the abdomen was under pressured to a forward bending position.Thus,shorter stab-resistant materials at the vest front have less movement restriction.Therefore,we discovered that contact area and pressure should be considered in the design of stab-resistant vests to improve the comfort of the wearer.
