<p>The fixing for a visor (4) to a crash helmet (2) comprises elastically deformable brackets (1), that can be deformed perpendicularly to their surface. The brackets are fixed at one extremity to each side of the helmet. The free extremity of each strap (6) has a cylindrical stud (7), on the inside, which fits into a groove (8) in each lateral branch (9) of the visor. The strap can be made in synthetic material or in metal. In the lowered position the visor fits into a depression (5) in the helmet. In the raised position the strap is put under tension after moving forwards and upwards.</p> |
