Buckle up, fixing and rapid adjustment, espe cially for bevor-hull protection

摘要

Safety buckle, fastening and quick adjustment, especially for bevor of protective helmets, characterized by the fact that it is essentially constituted by a stirrup of synthetic rigid molded integral with the outer wall of the hull forming cap, by means a horizontal axis that allows limited rotational movement, comprising a body whose inner face has a trapezoidal cavity whose sides converge toward the horizontal axis that allows limited rotational movement, comprising a body whose inner face has a trapezoidal cavity whose sides converge toward the horizontal axis and whose outer face is pierced up to the point of said convergence of an opening through the entire thickness of the stirrup, and a hook of rigid synthetic material molded, one end of which is attached the bevor and the other has a complementary trapezoidal shape of the cavi ity of the stirrup, ending the top of the hook end in a protrusion engagable in the opening through the stirrup.
