Abstract
A protective helmet with a crown made of synthetic material comprises a fixing device with a strap and means for adjusting the head-band size. The wall of the crown is drilled in the direction of the thickness with a plurality of orifices for housing positioning knobs adjustable between a first adjustment position corresponding to a large head-band size, in which said knobs are inserted inside the orifices, and a second adjustment position corresponding to a small head-band size, in which said knobs are salient towards the inside of the crown, each positioning knob having gripping means accessible from outside the crown to press the internal bearing face of the knob directly against the user's head.
