CHIN STRAP CONNECTOR WITH VARIABLE BREAKING

摘要

A connector including: first part designed to be connected to crown of protective helmet, second part designed to be connected to crown of protective helmet and fitted in removable manner on first part, connecting part mechanically connecting first part and second part so as to form first mechanical connection, movable part moving between first and second positions and configured: to prevent first and second parts from coming detached from one another when the parts are subjected to first threshold tensile force, when movable part is in first position, to enable first and second parts to be detached from one another when the parts are subjected to second threshold tensile force lower than that of first threshold tensile force, when movable part is in second position. The invention also relates to protective helmet provided with one such connector, as well as to an assembly method of such connector.
