  • Patent number: 5219367
    Abstract: A firefighter's turnout apparel comprises a pair of pants wherein knee joint areas of lower leg sections are formed to include bellows at the bend of the knee joints for increased protection, flexion range, and comfort. The bellows interconnect material above and below the joint sections to reduce tightness at the outside of the joint areas and material bunching at the inside of the joint areas, permitting freer flexibility and reduced compression of thermal material. Added material in the bellows which extends around the outer joint area, produces a slight bend in the material at these points results in the turnout apparel having a more natural and comfortable shape through the knee joint region, improving the thermal protection due to the reduced compression. Additional thermal protection is provided by inclusion of an additional thermal layer in the bellows. In addition to improved thermal protection, the bellows reduce cuff travel of the pants to provide better protection of the ankle areas.

  • Patent number: 5031242
    Abstract: A firefighter's turnout apparel comprises a coat and a pair of pants, wherein the elbow joint and the knee joint sections are formed to include bellows at the bend of the joints for increased protection, flexion range, and comfort. The bellows interconnect material above and below the joint sections to reduce tightness at the outside of the joint areas and material bunching at the inside of the joint areas, permitting freer flexibility and reduced compression of thermal material. Added material in the bellows which extends around the outer joint area, produces a slight bend in the material at these points results in the tunrout apparel having a more natural and comfortable shape through the joint regions, improving the thermal protection due to the reduced compression. In addition to improved thermal protection, the bellows reduce movement of the cuffs of the apparel to provide better protection of wrist and ankle areas.

  • Patent number: 5027437
    Abstract: A suite for the support of the body in respect of acceleration forces has ducts running therethrough forming pressure bodies which are distributed among different suit areas and are filled with a pressure-generating medium, which serves at the same time as the thermal conditioning agent, which is supplied from a pressure supply unit which does not hinder the heat exchange between the body and the cooling medium so as to function as a heat suit. The comfort of wear is improved with simultaneous protection against acceleration forces and a tempering of the body by circulating a heat carrier medium which can flow through at least individual areas of the suit. The areas are connected to a heat exchanger.

  • Patent number: 5007112
    Abstract: An improved one-piece protective coveralls of the type affording a barrier and thermal protection against hot and/or corrosive liquids. The coveralls include a generally continuous outer shell of woven aramid fabric covered by a liquid impervious layer and a corresponding inner multilayer thermally insulating liner inside of the outer shell. The inner liner is fabricated from at least one layer of low density nonwoven fabric fastened to a woven fabric. The improved coveralls include an elongate underarm opening under each arm of the liner extending downwardly from the position of the wearer's armpit into and along the underside of the sleeve and downwardly into and along the side of the torso portion. An elongated leg inseam opening is provided on the underside of the torso portion of said liner fabric and which extends from position of the wearer's crotch downwardly into and along the inside of each leg.

  • Patent number: 5001781
    Abstract: A firefighter's garment having enhanced thermal insulation qualities while also having minimum weight and maximum flexibility. The firefighter's garment has an outer shell of abrasion resistant and flame resistant material, within the outer shell is a layer of moisture resistant material, the layer of moisture resistant material covers a layer of thermal insulation which has given thermal insulation qualities. Attached to the layer of thermal insulation material which has given thermal insulation qualities is a layer of thermal insulation material which has greater thermal insulation qualities. The layer of thermal insulation material which has greater thermal insulation qualities is positioned within the firefighter's garment in the regions of the firefighter's garment which are subjected to the highest heat loads.

  • Patent number: 5001783
    Abstract: A firefighter's garment as disclosed herein may be a coat or trousers or a vest. The garment has an outer layer, an intermediate layer, and an inner layer. A spacer element or elements are positioned between two of the layers of the garment. The spacer element or elements in the firefighter's garment establish and maintain an air space or air spaces between the layers of the garment, even when localized pressure or weight is applied to portions of the garment. Thus, the firefighter's garment has excellent heat insulation qualities without being heavy and/or bulky. Thus, a firefighter wearing the garment is continually protected and is subject to minimum stress and is able to work more effectively than a firefighter wearing a firefighter's conventional garment.

  • Patent number: 4959876
    Abstract: A fireman's coat of the type which has an outer shell and a detachable liner for the outer shell and side pockets formed in opposite sides of the outer shell also has visible indicator patches on each side in close proximity to the open end of each pocket. The indicator patches have a sufficient extent to be clearly visible from the front, back and sides of the outer coat when the coat is worn by a fireman in use. A narrow opening is formed in each side of the outer shell in close proximity to the open end of each pocket. A pocket flap is attached to each side of the liner so that it can extend through one of the narrow openings formed in the sides of the outer shell. Velcro fasteners are provided for securing each pocket flap in an outwardly overlying relationship with respect to the outer shell to close the open end of its associated pocket and to overlie and obscure the visible indicator patches associated therewith to clearly indicate that the liner is located in the outer shell in use.

  • 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.
