Abstract In a fireman's helmet of the type having an outer shell and an impact resistent inner shell and a liner which has an upper band portion and an apron portion extending a substantial distance below the upper portion, the improvement wherein the upper band portion of the liner is arranged to extend around a lower marginal portion of the inner shell and is clamped between the lower marginal edge portion and an opposing face of the outer shell to be retained therebetween. A suspension anchor is provided for securing the head mounting harness to the impact resistant inner shell which comprises a short strasp of a substantially rigid material having a sufficient length to extend through a mounting loop formed at the end of a web of the mounting harness. The short strap has a pair of anchoring legs projecting therefrom at opposite ends thereof which have sufficient length to project into the body of the inner shell to anchor the harness which is supported by the short strap in use. The anchoring legs which project from the short strap have a greater length than the gap which is formed between the inner and outer shells of the helmet thereby to prevent the removal of the suspension anchors while the inner shell is nested in the outer shell.
In a fireman's helmet of the type having an inner shell which consists of a skin member and a foamed plastic member which is secured to and extends over the skin member, and a plurality of head band mounting tabs, the improvement of; tab mounting slots opening through the skin member at spaced intervals about a perimeter of the head receiving recess of the skin, said slots being elongated and having a predetermined length in the direction of said perimeter, said head band mounting tabs each having a proximal end portion which is proportioned to pass through the tab mounting slot in which it is to be mounted in use, said proximal end portion having lugs projecting from opposite ends thereof, said lugs being foldable with respect to the distal portion of the tab between an inner position overlying the proximal end portion to permit the proximal end portion to pass through a mounting slot and an extended position projecting laterally from the proximal end in which the lugs form locking shoulders which prevent removal of the tabs from the mounting slots and means for sealing the slots after the tabs have been mounted therein to prevent passage of plastic foam therethrough during the manufacture of the inner shell.
