Hohenstein to research on hygienic properties of helmets

In addition to the known head measurements from the ergonomics standard, the scientists at the Hohenstein Institute will be taking additional measurements and evaluate these to derive characteristic head morphologies. In addition to head shape, the project will also research facial measurements and provide dimensional descriptions, meaning possible dimensional correlations between the eye, nose, mouth and ear areas.

The categorising of these morphologies into representative head shapes for men, women and children will be an important step. In the end, interested manufacturers will have access to specific sizing systems describing the current head and face dimensions to be used as a basis for the design of head protection systems. There will also be standardised, realistic virtual average 3D head shapes.

In addition to fit-specific criteria, physiological aspects of moisture wicking have a substantial influence on wearing comfort. The materials used influence the climatic conditions inside a helmet. It is therefore important to optimise the textile interiors of helmets with regard to clothing physiology and hygiene. Ski helmets for example are meant to protect against the cold as well as ensure moisture wicking.

The hygienic properties in turn have been completely disregarded until now, even though they play an important role, for example for rental helmets. Increased sweating inside the head protection generates a warm and humid climate which diminishes wearing comfort while also creating ideal conditions for the growth of microorganisms. This results in unwanted odours and can trigger the development of scalp infections.
