The invention relates to improvements to a skull protection cell formed by an outer helmet (11, 20) internally lined with an absorptive material (12, 12') which comprises a first, rigid or semi-rigid layer (21) of closed-cell foam immediately under the helmet and in contact with a second layer (22) of open-cell viscoelastic foam, the interface between the first and second layers intelocking via recesses (24) in the first layer into which complementary and cooperating projections (23) provided in the second layer extend. Supports made of an absorptive material are further provided in the region of the mandible (32) and in the maxillary regions (33, 34) and mastoid regions (35). When closed, the visor (37) fits into the corresponding opening of the skull protection cell, and the visor is opened in two steps, a first step in which it is moved forward and a second step in which it is rotated upwards. The skull protection cell (CPC) further comprises a detachable chin guard (54) with an unlocking mechanism actuated by means of buttons (51) located on either side of the helmet. |
