Ergonomic Analysis of a Firearm According to the Anthropometric Dimension

The paper summarizes the results of an ergonomic analysis of firearms with regard to anthropometric dimensions of selected populations. For evaluation 3D digital human models, which represent currently the best technology, have been used. Analyses are performed for three major population groups (Americans, Europeans and Asians). Ranges to controls (e.g. lock, trigger, etc.) are critically evaluated. The grip of the firearm according to the position of shooters wrist is also a subject to critical analysis. At the end of the paper the deficiencies found are discussed as well as a bad situation regarding the availability and timeliness of anthropometric dimensions of Czech population. Further work that is described will be focused on the creation of national anthropometric database. The database shall include the dimensions of the hand and will be created according to the rules of EN ISO 15535. The data will be suitable for the design of other hand tools from various sectors.
