ABSTRACT:
A head protector for a helmet, in which at least one groove is provided in a predetermined inner surface of an impact-on-the head absorbing liner, the predetermined inner surface including at least a top portion to face the vertex of a person with a helmet on, but not substantially including at least a front portion to face the person's sinciput and a plurality of projections at least partially surrounded by the groove are provided in the predetermined inner surface. Owing to this head protector, the rigidity of the whole of the impact-on-the-head absorbing liner is not worthlessly reduced and, nevertheless, both the maximum acceleration and HIC due to an impact are effectively reduced.
