Electroacoustic communication device for use on protective headgear

A protective helmet of the type that includes a device for attaching a respiratory mask. This arrangement includes an arrangement for adjusting the position of the attachment device, enabling the positioning thereof in at least two positions and the attachment device is in one piece with an attachment part adjustably affixed to the shell of the helmet to enable modifying the position thereof.

Protective helmet with an anchoring device for a respiratory mask

A protective helmet partially formed by a main outer shell having a longitudinal plane of symmetry, and of the type having a holding and positioning arrangement adapted to allow its fastening to the user's head, the arrangement a set of flexible straps, wherein the holding and positioning arrangement has a mechanism for adjusting the length of the straps, at least one element of which is constituted by a pulley.
