Anthropometric helmet design
conference paper
A good understanding of the dimensions of the head is necessary to design a helmet sizing system that accommodates the user population. Traditionally most helmet sizes are proportionally scaled versions of the basic design, based on the distribution of head circumference of the user population. These sizing systems do not take the low correlation into account between head length (fore head to back of head) and head breadth. Consequence is that a lot of users are forced to wear a helmet that is needlessly too large and too heavy for them. A method has been developed to create a sizing system that takes these head dimensions into account and that provides the dimensions of the different helmet sizes which are optimal for the intended user population.
In addition to the head breadth and length, the 3 D-shape of the head is important for optimal helmet design. The aim is to minimise the distance between the skull and helmet shell as much as possible, taking into account a certain safety margin for indenture. Ideal is to make a 3D-copy of a person's head and make an individual helmet shell. Unfortunately, this method is too expensive. For production reasons it is best to strive for easy forms. U sing a shape analysis of the human head an optimal 3 D-helmet shape is proposed.

Hoofden kunnen beschreven worden als een kaas met kleine platte zijden en dus gekarakteriseerd worden met 2 parameters. Een algoritme voor misfit van helmen vertaalt dit in het benodigde aantal maten.
