Abstract: Crown pad of flexible material including a central body portion and a plurality of radially disposed members for flexing inwardly to conform to the crown of a person's head. The crown pad is for being connected to the central portions of head straps residing interiorly of a head-protective helmet. The flexible crown pad may be compressible causing the crown pad to attenuate or absorb some force or energy upon an object striking the helmet. A head-protective helmet in combination with such crown pad.

Abstract: Combination head and eye-protective apparatus including a head-protective helmet provided with a brim including a rearward brim portion, and goggles including an elastic member and a mounting member mounted to the elastic member and for wedgedly engaging the rearward brim portion to mount the goggles to the helmet. Goggles including a frame having outer portions, eye-protective lens mounted in the frame, an elastic member having outer ends and a rearward central portion and a mounting member mounted to the rearward central portion of the elastic member, the outer ends of the elastic member mounted to the outer end portions of the frame.

Abstract: Head-protective helmet including a single mounting means, e.g. a plurality of anchor clips, which at least assist in mounting an inner impact shell to the outer shell, mount a head band to the outer shell, mount a plurality of head straps to the outer shell, and depending upon the material of which the mounting means is made may absorb energy created upon a downwardly acting force being applied to the outer shell. A head band including pivotally interconnected forehead member and nape device. A mounting member particularly useful for mounting head-protective helmet components together.

Abstract: Combination head and eye protective apparatus including a head-protective helmet having a nape device for fitting the helmet to the head of a wearer of the helmet, and goggles including a mounting member for mounting the goggles to the nape device. Goggles including a goggle frame, eye protective lens mounted in the frame, and mounting member for mounting the goggles to the nape device of a head-protective helmet.

Abstract: A protective thermal overjacket for being worn over an outer protective shell and/or inner thermal liner of a person such as a firefighter, and for providing additional flame and thermal protection to the upper torso of the firefighter particularly the upper chest, upper back, and upper arms of the firefighter's body. Fasteners may be provided for interconnecting the collars of the protective thermal overjacket, the inner thermal liner and the outer protective garment; alternatively, the collar of the protective thermal overjacket may be provided with a fastener for fastening the collar of the overjacket around the collar of the outer protective garment.

Abstract: A generally hands-free, voice communication system in combination with a head-protective helmet. The helmet protects the wearer's head and the communications system permits voice communications between journeyman personnel, e.g. firefighters, police, military, industrial, hazardous material handling personnel, in relatively close proximity with each other and between journeymen and a group leader; and the group leader's communication system to also permit relatively long-range communication between the group leader and a relatively distant communications center such as a fire engine or distant fire company, base station or repeater.

Abstract: In combination, a protective helmet including an outer shell and an inner impact shell, a protective facepiece, and interconnecting members for mounting the facepiece to the inner impact shell and for placing the facepiece into sealing engagement with the face of a wearer of the helmet.

Abstract: A self-contained breathing assembly of the positive pressure type including a remotely positioned improved pressure demand regulator for substantially instantaneous response for breathing air having reduced operating parts substantially reducing potential breakdown and wherein there is provided a gas flow disconnect assembly between the user facepiece and gas conduits.

Abstract: An assembly is disposed on a helmet for monitoring predetermined thresholds of ambient thermal condition of the helmet. Such assembly includes at least one thermistor for sensing the status of an ambient thermal condition and a signal comparator for detecting each predetermined threshold. Individual LED's visually indicate when each predetermined threshold is reached, while an audible alarm indicates when a hazardous predetermined threshold is reached. The audible alarm is further utilized to indicate if the battery voltage is under a predetermined threshold which is predicated on the breakdown voltage of a reference diode when a test switch is closed. A temperature responsive switch is also included to conserve the life of the battery by activating and deactivating the assembly about a predetermined temperature level.

Abstract: There is disclosed a pressure monitoring device for self-containing breathing apparatus including visual indicators disposed in the field of view from the headpiece to monitor when predetermine pressure levels are reached in the tank which supplies gas to that headpiece. The predetermined pressure levels are referenced to the residual tank pressure at which the required breathing gas flow is not sustained and visual alarm provisions anticipate those predetermined pressure levels which are critical, in some embodiments of the invention. A cost effective transducer of reduced pressure range senses the tank pressure and noise is eliminated from the transducer signal by common mode rejection in still other embodiments.

Abstract: A protective helmet assembly including an outer impact shell and an inner impact attenuation liner assembly wherein the inner liner assembly includes an adjustable headband assembly comprised of a front headband member and a rear spring-loaded headband member under the control of a chinstrap into a fitted configuration about the head of the user by a clip assembly. The inner impact attenuation liner assembly is mounted within the outer impact shell to separate therefrom under predetermined load conditions.

Abstract: As improved protective helmet assembly including an outer shell and an inner impact attenuation liner assembly wherein a chinstrap assembly is mounted to the inner impact attenuation liner assembly and the inner impact attenuation liner assembly is mounted within the outer impact shell to detach under predetermined load conditions from the outer impact shell.

Abstract: There is diclosed a self-contained breathing assembly of the positive pressure type including a remotely positioned improved pressure demand regulator for substantially instantaneous response for breathing air having reduced operating parts substantially reducing potential breakdown and wherein there is provided a gas flow disconnect assembly between the user face mask and gas flow conduits.

Abstract: There is disclosed a protective garment having an outer protective shell, a moisture barrier, and an inner thermal liner wherein the inner thermal liner is formed of a non-woven web of a wool blend and another fiber mounted to a woven web of a wool blend and another fiber wherein the wool content of the layer of woven material is greater than the wool content of the non-woven layer.

Abstract: There is disclosed a self-contained breathing apparatus of the positive pressure type wherein there is provided a pneumatic servo mechanism responsive to a pressure sensor to drive a breathing storage chamber by expansion of an oxygen containing gas from a storage tank therefor.

Abstract: There is disclosed a protective garment having an outer protective shell, a moisture barrier, and an inner thermal liner wherein the inner thermal liner is formed of a non-woven web of a wool blend and another fiber mounted to a woven web of a wool blend and another fiber wherein the wool content of the layer of woven material is greater than the wool content of the non-woven layer.
