Abstract
A releasing device for enabling rotation of a chin guard hinged to the sides of the cap of a crash helmet, in particular a helmet for motor-cyclists, which comprises at least one mechanism for engagement/release of the chin guard with respect to the cap, first means for actuation of the engagement/release mechanism and second means for inhibition of release, in which said first and second means can be actuated by the user. The aforesaid second means for inhibition of release prevent, when not actuated by the user, operation of the first actuation means and/or of the engagement/release mechanism.
Claims20
A releasing device for enabling rotation of a chin guard, hinged to the sides of the cap of a crash helmet, in particular for motor-cyclists, of the type which comprises at least one engagement/release mechanism for engagement/release of the chin guard with respect to the cap, first actuation means of said at least one engagement/release mechanism, and second inhibition means for inhibiting release, said first and second means being actuatable by a user, said device being characterized in that said second means prevent, when not actuated by the user, operation of said first actuation means and/or of said at least one engagement/release mechanism.
A method for releasing and enabling rotation of a chin guard hinged to the sides of the cap of a crash helmet, in particular a helmet for motor-cyclists, and constrained thereto by means of at least one mechanism for engagement/release for disabling/enabling rotation of the chin guard with respect to the cap, said helmet comprising first means for actuation of said engagement/release mechanism and second means for inhibition of release, said first and second means being actuatable by a user and said second means preventing, when not actuated by the user, operation of said first actuation means and/or of said at least one engagement/release mechanism, said method being characterized by the steps of:
- actuating first said second inhibition means for enabling the operation of said first actuation means and/or of said at least one engagement/release mechanism;
- and
- then actuating said first means for actuation of the engagement/release mechanism.
