Abstract (en)
[origin: US4734940A] A device ensuring the adaptation of a removable respiratory mask onto a protection helmet includes two attachment arms, each one of the arms having first and second elements slidingly engaging one another. The first element is pivotally connected to one side of the mask whereas the second element is provided with a hook coacting with a catch located on the headpiece of the helmet. An interior spring is compressed between a support surface of the first element and a flange of a movable rod. The second element has a latching lever for latching the rod in any desired position to adjust or readjust the compression of the spring, and accordingly, the application force of the mask onto the face.
