ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a collar system incorporated into a firefighter's coat. This invention represents an improvement over the construction disclosed in U.S. Pat. No. 5,638,547, the disclosure of which is incorporated herein by reference.
The above patent explains the importance of maintaining water-tight integrity at the juncture of the outer shell and the collar portion of the coat. This is a particular problem when the thermal liners employed with such coats are removable from the shell and collar portion of the coat to enable cleaning protocols to be carried out.
The above patent also discusses the prior art and the problems associated therewith. The objective of the present invention is to provide water-tight integrity at the juncture of the body portion of the shell and the collar portion of the coat, while providing an arrangement which permits a separate thermal liner to be removed from the body portion and the collar portion to be washed and dried when desired. The present invention incorporates a construction which provides superior results when used in firefighting operations.
SUMMARY OF THE INVENTION
An outer shell is stitched to an outer collar part which in turn is stitched to an inner collar part. A first moisture barrier is disposed adjacent to the inner collar part and is stitched thereto. A second moisture barrier is disposed between the inner collar part and the outer collar part and is stitched to the outer collar part. A third moisture barrier is disposed between the second moisture barrier and the outer collar part and is stitched to the outer collar part. A conventional liner has an upper edge portion with hook and loop fastening portions supported on opposite sides thereof. In referring hereinafter to the inwardly and outwardly facing sides of various components of the invention, the collar is assumed to be in an upright operative position so that the collar extends vertically upwardly from the outer shell to protect a firefighter's neck during firefighting activities. A hook and loop fastening portion is supported on the outwardly facing side of the inner collar part for engaging the hook and loop fastening portion on the inwardly facing side of the liner. A further hook and loop fastening portion is supported on the inwardly facing side of the second moisture barrier for engaging the hook and loop fastening portion on the outwardly facing side of the liner. With this arrangement, the liner can be completely removed from the shell and collar portion of the coat and subsequently reattached to the coat in proper operative position.
The liner includes a thermal barrier and a liner moisture barrier which are stitched to one another. The fastening portion on the outwardly facing side of the inner collar part is stitched to the inner collar part and the first moisture barrier, while the cooperating fastening portion on the inwardly facing side of the liner is stitched to the thermal barrier of the liner. The fastening portion on the outwardly facing side of the liner is stitched to the liner moisture barrier, while the cooperating fastening portion on the inwardly facing side of the second moisture barrier is stitched to the second moisture barrier. Conventional seam seal tape is disposed on the inner facing side of the liner moisture barrier adjacent to the fastening portion thereon, and seam seal tape is disposed on the outwardly facing side of the second moisture barrier adjacent to the fastening portion thereon, thereby preventing moisture from passing through the second moisture barrier and the liner moisture barrier at the stitching holding the fastening portions thereon.
The third moisture barrier is stitched to the outer collar part by a plurality of spaced lines of stitching to form air pockets between the third moisture barrier and the outer collar part. These air pockets provide thermal insulation at the inner side of the outer collar part.
