Abstract
A protective garment, such as a protective coat or protective coveralls, for a firefighter or for an emergency worker is provided with a shoulder pad, which is worn between the protective coat and a shoulder of a wearer. The shoulder pad is attached detachably, as by a hook-and-loop fastener, to a shoulder strap of suspenders worn by the wearer or to the protective garment. The shoulder pad contains a bladder, which is adapted to be inflated with a suitable fluid, preferably air, so to increase an air space between the protective coat and the shoulder of the wearer. The air space provides thermal insulation between the protective garment and the shoulder of the wearer.
Description




TECHNICAL FIELD OF THE INVENTION




This invention pertains to an improvement in a protective garment, such as a protective coat or protective coveralls, for a firefighter or for an emergency worker. This invention contemplates that the protective garment is worn with a shoulder pad containing an inflatable bladder.




BACKGROUND OF THE INVENTION




Commonly, a firefighter or an emergency worker wears protective garments, such as a protective coat or protective coveralls having plural layers, which include an outer layer providing abrasion resistance, an intermediate layer providing a moisture barrier, and an inner layer providing thermal insulation, and such as protective trousers having similar layers and being worn with suspenders, which have shoulder straps.




As exemplified in U.S. Pat. Nos. 5,572,991, 5,274,849, and U.S. Re. Pat. No. 34,094, it is known that an air space in such a garment provides thermal insulation. U.S. Pat. No. 5,274,849 discloses a spacer element, which is interposed between two layers of such a garment so as to maintain an air space therebetween.




SUMMARY OF THE INVENTION




This invention provides, in a protective garment for a firefighter or for an emergency worker, an improvement wherein the protective garment is provided with a shoulder pad, which is to be worn between the protective coat and a shoulder of a wearer. The shoulder pad is attached detachably, as by a hook-and-loop fastener, to a shoulder strap of suspenders worn by the wearer or to the protective coat. The shoulder pad contains a bladder, which is adapted to be inflated with a suitable fluid, such as a gas, liquid, or gel, so to increase an air space between the protective coat and the shoulder of the wearer. The air space provides thermal insulation between the protective coat and the shoulder of the wearer.











BRIEF DESCRIPTION OF THE DRAWINGS





FIGS. 1 and 2

are fragmentary, perspective views of a protective coat, as provided with two shoulder pads, each of which is worn between the protective coat and a shoulder of a wearer and each of which is attached detachably to a shoulder strap of suspenders worn by the wearer, in a preferred embodiment of this invention.




In

FIG. 1

, the shoulder pad and the shoulder strap are shown in broken lines, as concealed by the protective coat. In

FIG. 2

, the protective coat is broken away and is shown in two positions, which correspond respectively to an inflatable bladder in the shoulder pad being inflated and being deflated.





FIGS. 3

,


4


, and


5


show the shoulder pad, apart from the protective coat.

FIG. 3

is a plan view.

FIG. 4

is a side view.

FIG. 5

, which shows the shoulder strap, is a fragmentary, sectional view taken along line

FIG. 2

, in a direction indicated by arrows.





FIGS. 6

,


7


, and


8


are fragmentary, sectional views showing alternative embodiments of a shoulder pad containing an inflatable bladder and attached detachably within and to a protective coat. In

FIG. 6

, the shoulder pad is sewn to the protective coat. In

FIG. 7

, a hook-and-loop fastener is used to attach the shoulder pad detachably within and to the protective coat. In

FIG. 8

, two hook-and-loop fasteners are used to attach the shoulder pad detachably within and to the protective coat.











DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS




As illustrated in

FIGS. 1 and 2

, a protective coat


10


worn by a firefighter is provided with two shoulder pads


20


, each of which is worn between the protective coat


10


and a shoulder of the firefighter. Each shoulder pad


20


is attached detachably, in a manner described below, to a shoulder strap


22


of suspenders worn by the firefighter.




As illustrated in

FIGS. 2 through 5

, each shoulder pad


20


has a pouch


24


and a flap


26


, which extends from the pouch


24


, which is wrapped around the shoulder strap


20


, and which is attached detachably to the pouch


24


, via a hook-and-loop fastener


30


. The hook-and-loop fastener


30


comprises a hook-faced strip


32


, which is sewn to the pouch


22


, and a loop-faced strip


34


, which is sewn to the flap


24


.




As illustrated in

FIG. 5

, the pouch


24


contains a bladder


40


, which is made of a synthetic rubber and which is inflatable with a suitable gas, such as air, or with a suitable liquid, such as water, or with a suitable gel, air being a preferred fluid to inflate the bladder


40


. As illustrated in

FIG. 3

, the bladder


40


has a valve


42


, which extends outwardly though a hole


44


in the pouch


24


and through which the bladder


40


is inflatable. Any suitable means for providing a pressurized fluid, such as an air pump or an air-pressurized canister, may be used for inflating the bladder


40


.




Each shoulder pad


20


is similar to shoulder pads available commercially heretofore from Dielectrics Industries of Chicopee, Mass., as shoulder-cushioning pads for postal workers who are required to carry heavy bags, via shoulder straps. Moreover, the inflating means may be similar to any of the inflating means available commercially heretofore from Dielectrics Industries, supra.




In each of the alternative embodiments illustrated in

FIGS. 6

,


7


, and


8


, a shoulder pad is attached within and to the protective coat


10


. In the embodiment illustrated in

FIG. 6

, the shoulder pad comprises a fabric panel


50


, which is sewn to the protective coat


10


so as to confine an inflatable bladder


40


between the fabric panel


52


and the protective coat


10


. In the embodiment illustrated in

FIG. 7

, the shoulder pad comprises a pouch


60


, which confines an inflatable bladder


40


and which is attached detachably to the protective coat


10


, via a hook-and-loop fastener


30


. In the embodiment illustrated in

FIG. 8

, the shoulder pad comprises a fabric strip


70


, which is wrapped around an inflatable bladder


40


, which is attached detachably to itself, via a hook-and-loop fastener


80


similar to the hook-and-loop fastener


30


, and which is attached detachably to the protective coat, via a hook-and-loop fastener


90


similar to the hook-and-loop fastener


30


.




In each embodiment illustrated and described herein, whenever the firefighter perceives a need for further insulation, the firefighter can operate the inflating means so as to inflate the inflatable bladders of the shoulder pads, whereby to increase air spaces providing thermal insulation between the protective coat and the shoulders of the firefighter.




Although the protective garment is a protective coat in each embodiment illustrated and described herein, this invention may be embodied in another protective garment, such as protective coveralls.
