<p>A head protector for a safety helmet, in which at least one groove (31.34,62) is provided in a predetermined area of the inner surface of an impact-on-the-head absorbing liner (15), the predetermined area including at least a top portion to be faced the vertex of a person with a helmet on, but not substantially including at least a front portion to be faced the person's sinciput and, thereby, a plurality of projections (35.40,51.53,61) at least partially surrounded by the groove (31.34,62) are provided in the predetermined area. Owing to this head protector, the rigidity of the whole of the impact-on-the-head absorbing liner (15) is worthlessly reduced and, nevertheless, both the maximum acceleration and HIC due to an impact are effectively reduced. <IMAGE></p> |
