  • Patent number: 4972520
    Abstract: A firefighter's hood which covers the upper portion of a firefighter. The hood normally has a shoulder section and a neck section and a head section, to cover those portions of the firefighter. The head section covers the head of the firefighter and has an opening to expose the face of the firefighter. The major part of the head section is made of thermal barrier material having given heat insulation qualities. However, the head section has an upper part which is adapted to be positioned at the upper portion of the head of the firefighter who wears the hood. The upper part of the head section of the hood has significantly less heat insulation qualities, so that heat can escape from the head of the firefighter and thus stress upon the firefighter which results from heat is reduced.

  • Patent number: 4922552
    Abstract: A firefighter's garment which includes a layer of protective material in which the layer of protective material is provided with a major portion which has a high degree of thermal protective properties. The layer of protective material also has sections which have a lesser degree of thermal protective properties. The protions of the layer of protective material which have a high degree of thermal protective properties are positioned at locations which require maximum thermal protection. The portions of the layer of protective material which have a lesser degree of thermal protective properties are located at positions which require less thermal protection. The portions of the layer of protective material which have a lesser degree of thermal protective properties also have greater flexibility and less bulk and less weight. Thus, the possibility of stress upon the firefighter is not effectively decreased when firefighter body posture during firefighting and the role of the protective equipment is considered.

  • Patent number: 4768233
    Abstract: A firefighter's garments include a coat and trousers. Each of these garments has an outer shell and an inner liner. The inner liner has a section secured thereto which is attached to the outer shell and which serves as an important part of the outer shell. Therefore, when the inner liner is removed from the garment, the garment is not readily usable by a firefighter. In one embodiment of the invention the section which is secured to the inner liner serves as an element for attaching together two separable parts of the front portion of the coat or trousers. Therefore, when the inner liner is removed from the outer shell, the front parts of the garment cannot be attached together and the garment cannot be used by a firefighter. In another embodiment of the invention, the inner liner is attached to the cuff portions of the trousers and to the cuff portions of the coat. The cuff portions may be significant parts of the garment.
