DETAILED DESCRIPTION

(3) With reference to FIG. 1, a protective hood 10 is provided for use by firefighters, emergency responders, and others who need protection from a hazardous environment that may include extreme heat, fire, dangerous chemicals, water, biohazards, and the like. The protective hood 10 uses both woven and knit textile materials to form a single hood, with each of the materials being utilized in the hood 10 at locations where their respective positive qualities are most needed and desirable, based upon the particular desired use of the protective hood 10. In this regard, for example, if the hood is intended to be worn with a face mask/face piece, it may desirable to utilize woven materials (coated/laminated or uncoated) in certain locations that would not be desirable in hoods that are not intended to be worn with a face mask or face piece. As another example, some protective garments worn in combination with the hood may be best suited for a woven material to be utilized in the drape, while other garments may be bested suited for a knit material to be utilized in the drape.

(4) The hood 10 includes a crown portion 12 to cover the top of a wearer's head, and a lower or head portion 14 extending downward from the crown portion 12 to cover the back, sides and front of the wearer's head and, in the illustrated embodiment, part of the wearer's neck, with a face opening 16 for at least the eyes of a wearer. The face opening 16 is defined (surrounded) by a peripheral seam or edge 18 that surrounds the face opening 16. The hood 10 further includes a front drape 20 and a rear drape 22 that extend downward from the head portion 14 to cover at least a portion of the front and back, respectively, of the neck and shoulders of the wearer. The crown portion 12, head portion 14, peripheral edge 18, front drape 20 and rear drape 22 will be permanently connected to each other by seams 24 using a suitable seam connection, such as by sewing a stitched connection (as shown by the stitch lines at 30, 32 and 34 in FIG. 1) or by bonding, to provide two suitable examples.

(5) As seen in FIG. 1, the crown portion 12 covers a minimum of 10% of wearer's head in the illustrated embodiment. In terms of human anatomy, the crown portion 12 of the typical hood 10 will extend from at or adjacent the brow ridge, over the frontal skull bone, over the coronal suture, and to the parietal bone, stopping short of or extending no further than the lambdoid suture of a wearer's head. Laterally, the crown portion 12 of the typical hood 10 will stop short of the sphenoid and temporal bones on each side of a wearer's head.

(6) In the illustrated embodiment, at least one of the crown portion 12, the peripheral edge 18, the front drape 20, and the rear drape 22 is formed from at least one layer of knit material, and all or part of the head portion 14 includes, or is formed from, at least one layer of a woven material. In one form of this embodiment, each of the crown portion 12, the peripheral edge 18, the front drape 20 and the rear drape 22 will include, or is formed from, at least one layer of woven textile if the respective part 12, 18, 20 or 22 is not formed from at least one layer of knit material. In this regard, in most embodiments the at least one layer of woven textile will extend over the entirety of any of the crown portion 12, the front drape 20, and the rear drape 22 that includes the at least one layer of woven material. Similarly, in most embodiments the at least one layer of knit material will extend over the entirety of any of the crown portions 12, the front drape 20, and the rear drape 22 that includes the at least one layer of knit material.

(7) In one embodiment of the hood 10 that will be highly desired in applications where a wearer must also don a face mask and a helmet, the peripheral edge 18 is formed from a combination of one or more layers of knit material and one or more layers of woven material. As best seen in FIG. 1, in this embodiment, the peripheral edge 18 includes an innermost band 36 located between the line of stitching 30 and the inner most lip or edge 38 (often referred to as the leading edge) of the peripheral edge 18 and encircling the face opening 16. This innermost band 36 is formed from one or more layers of knit material, with an elastic member (not illustrated) encircling the face opening 16 and encased within the layers of knit material to allow the face opening 16 to be adapted to the particular configuration and size of each wearer's face. The peripheral edge 18 of this embodiment also includes a brow band 40 at the top of the face opening 16 that extends space longitudinally between stitch lines 30 and 34 and laterally between seam lines 24A and 24B which extend downward from the seams 24 to the face opening 16. The brow band 40 is also formed from one or more layers of knit material and also aids in allowing the face opening 16 to be adapted to the particular configuration of each wearer's face. Last, the peripheral edge 18 of this embodiment includes a woven band 42 that extends over the remainder of the peripheral edge 18 between the stitch lines 30 and 34 and between the stitch lines 24A and 24B to define the sides and bottom of the peripheral edge 18. The woven band at 42 is formed from one or more layers of woven material. This allows for woven material to extend below and from the seal of the facemask that is exposed below the helmet of a wearer, while the brow band 40 allows the sweatband of a helmet to engage a knit material at the face opening 16.

(8) In one embodiment, the crown portion 12 is formed from a knit material and the remaining parts 14, 18, 20 and 22 of the hood 10 include, or are formed from at least one layer of woven material.

(9) In another embodiment of the hood 10, the crown portion 12 and peripheral edge 18 are formed from knit material, and the head portion 14, or at least part of the head portion 14, and the front and rear drapes 20 and 22 include, or are formed from, at least one layer of woven material.

(10) In another embodiment of the hood 10, the crown portion 12 and at least one of the front and rear drapes 20 and 22 are formed from a knit material and the remaining parts of the hood 10 include, or are formed from, at least one layer of woven textiles.

(11) In another embodiment of the hood 10, the crown portion 12, the peripheral edge 18 and at least one of the front and rear drapes 20 and 22 are formed from a knit material, and the remaining parts of the hood 10 include, or are formed from, at least one layer of woven textiles.

(12) In yet another embodiment of the hood 10, the crown portion 12, the peripheral edge 18, the head portion 14, or at least part of the head portion 14, all include, or are formed from, at least one layer of woven textile, and at least one of the front and rear drapes 20 and 22 is formed from a knit material.

(13) In another embodiment of the protective hood 10, the crown portion 12, the head portion 14, or at least part of the head portion 14, include, or are formed from, at least one layer of woven textile, and the peripheral edge 18 and at least one of the front and rear drapes 20 and 22 are formed from a knit material.

(14) The knit materials and the woven materials can be of any suitable type for a protective gear, many of which are known. In many applications it will be desirable for the materials to be fire resistant and/or thermal insulative to protect the wearer.

(15) As disclosed herein, the protective hood 10 combines both woven and knit textile materials into a single hood 10 wherein the respective positive qualities of the knit material and the woven material are located in those areas of the hood 10 where they are most needed and desirable, and thereby provide advantages over protective hoods that are either all woven or all knit.

(16) It should be understood that the illustrated embodiment shows only one possible construction for the protective hood 10 as disclosed herein and that this disclosure anticipates modifications to that particular embodiment. For example, the size and extent of each of the crown portion 12, the head portion 14, the face opening 16, the peripheral edge 18, the front drape 20, and the rear drape 22 may vary depending upon the requirements of each particular application and the size and shape intended for the particular wearer's head. By way of further example, the location and shape of each of the seams 24, 30, 32 and 34 may vary, again depending upon the particular requirements of each application. As yet a further example, the hood 10 may be produced without one of the front drape 20 and the rear drape 22, or without both the front drape 20 and rear drape 22. In another example, the peripheral edge 18 may be produced without an elastic member, and/or entirely out of knit material and/or entirely out of woven material, again depending upon the requirements of each particular application.
