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

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.
