Chin Strap Forces in Bicycle Helmets

摘要

The objective of this experimental investigation was to find out what dynamicforces bicycle helmet's retention system are subjected to when head impact accidents take place. The results were quantitative data of the retention system forces. Different helmet models were subjected to simulated accidents, of the type with the head first (with vertical and horizontal velocity) against a rigid asphalt surface. The chin strap forces developed in the accident simulations of the present study are low compared to the requirements of most of the existing standards for bicycle helmets.
