초등학교 저학년용 스포츠 보호대의 제품 특성 분석 및 착용감 평가

In this study, we investigated the overall characteristics of protective gear for children by obtaining data on commodities distributed in domestic and overseas online markets. Based on the information, a commercial product with popular design was purchased, evaluated for fit, and analyzed based on the 3D structure of the hard shell. Currently, the commercial products are free size or follow the S-M size system. Majority of the products that are sold are comparatively cheap and are distributed without presenting product certification and evaluation results. In domestic as well as overseas markets, PVC is the most widely used material for the hard shell and air mesh, sponge, or EVA is frequently used for the inner foam. In terms of design features, fastening is mainly accomplished by a stretchable knit inserted within an elastic strap or the use of an elastic strap alone; in addition, some products have a pull-on style. The hard shell shapes mostly comprise the O and X types, and products without holes to upgrade the air permeability outnumbered the perforated products. Also, the study results indicated that none of the products have a segmented hard shell design. Evaluation of wearing sensation showed that children most prefer a pull-on style type made of knit textile without a hard shell because it facilitates easier movement, and provides comfort to the knees. In addition, the hard shell is rated as comfortable for products with large curvature in the longitudinal section and the wearing method is affected by the comfort in wear.
