Abstract

Abstract The helmet may be secured to the wearer's head by an armor the two ends (14-15) of the pair of "V" shaped branches of which are anchored to two opposite points on the rear lateral part of the helmet to form, substantially an arched element apt to engage with the user's nape, while the free end of the third branch is anchored substantially to a mid point (30) of the helmet's rear edge. Said armor can be obtained with a pair of straps (12-13) made of flexible deformable material located above or within the usual nape protecting pad (10). Alternatively, the armor may consist of a frame (40) made of plastic material secured to the edge of the helmet's opening and incorporated in the nape protecting pad itself.
