Summary/Abstract: Very often while working or playing sports a person is exposed to a many hazards. One of the most dangerous threats is head injuries. We are not able to eliminate them completely. To minimize them, various types of head protection are used. Their design and construction are constantly changing and evolving, and the protective parameters are closely matched to the anticipated threats. New materials and technical solutions are used in the construction of helmets, which are aimed at increasing human safety and comfort of use, as well as reducing weight and increasing its functionality. Such goals can be achieved mainly thanks to the use of modern design software and simulation of behavior e.g. during shock absorption or by using shock absorbing materials with specially selected damping characteristics. This article contains information on modern design methods and computer simulation of the behavior of developed models of protective helmets during shock absorption. Shock absorbing materials with specially selected strength-deformation characteristics were also presented. These materials also provide high protective and functional properties.
