Abstract
The disclosure is a helmet, for example a pilot's helmet, including a shell and an attachable structure carrying optronic equipment. To facilitate manual fitting and removal of the structure on the shell by the wearer, the structure is equipped with mobile linkage parts that can take two stable positions, with a mechanism for locking the linkage parts in these positions, an open position used during the initial positioning of the structure on the shell, and a closed position in which the linkage parts lock the structure on the shell. Fitting and removal of the structure is further facilitated by the fact that the linkage parts can be opened or closed simply by pressing manually on two parts mounted symmetrically, one on each side of the shell, and that each position of the linkage parts is maintained by the mechanism for locking.
