<p>The visor (2) is for a crash helmet for motorcyclists, extremity having a fixing strap (2a) with a longitudinal slot (3). This is widened at two places (8) so that a stud (4) can engage in them, thus locking the visor in two positions. The straps are covered by two identical hollow shells (7) which are traversed near their open extremities (6) by the axle of the stud. The strap is introduced through the opening so that, due to the elasticity of its constitutive material, the slot can clip on to the stud and the visor can be easily removed in case of accident.</p> |
