Abstract
A protective helmet has a helmet cap and a shock-absorbing inner fitment in the form of a grille-like basket. The basket includes bosses pointing to the inner wall of the helmet cap exercising a shock-absorbing function based on their plastic deformation under an impact. The basket may be fastened to the helmet cap with a shock-absorbing effect directly at the fastening point, by providing a fastening boss for the fastening of the basket to the helmet cap. The fastening boss includes an end face having a through opening for firm contact against the helmet cap. The helmet cap has a through opening aligned with the through opening in the end face. Correspondingly, bolt-shaped fastener abut against the outer side of the helmet cap and the inner side of the end face, and are connected such that the end face pressed against the inner wall of the helmet cap.
