referring now to the drawings , and more particularly , to fig1 , a protective garment is generally shown at 10 . the protective garment 10 consists in the illustrated embodiment of a jacket 12 and trousers 14 , as worn by a firefighter . referring to fig2 , the jacket 12 is shown partly fragmented to illustrate its layer configuration . more specifically , the layer configuration has an outer shell 16 , a moisture barrier liner 17 , and a thermal barrier liner 18 . this layer configuration is used for both the jacket 12 and the trousers 14 . the outer shell 16 is made of heavy duty material that is flame -/ heat - resistant and tear -/ abrasion - resistant . for instance , the outer shell 16 is typically made of mixtures of kevlar ™ and nomex ™, or any other suitable material . the moisture barrier liner 17 is often found below the outer shell 16 . the moisture barrier liner 17 protects the wearer from high - temperature liquids , such as steam . as an example , the moisture barrier liner 17 is typically made of materials such as goretex ™ or any other similar materials in accordance with industry standards . the thermal barrier liner 18 is within the moisture barrier liner 17 . the thermal barrier liner 18 is an insulating layer that protects the wearer from the excessive heat , thereby reducing the risks of skin burns . for instance , the thermal barrier liner 18 is for instance made of different weights of nomex ™ or any other similar materials in accordance with industry standards . it is pointed out that , although three different layers have been described in a specific configuration , other layers ( such as strips of reflective material 19 ) or other configurations could be used with the protective garment 10 . as an example , the outer shell and the moisture barrier liner 17 may be integrally made of a single layer . similarly , the moisture barrier liner 17 and the thermal barrier liner 18 are typically peripherally sewn to one another . referring concurrently to fig1 and 2 , the jacket 12 has a torso portion 20 and arm portions 21 . thermal insulation pads are provided in the jacket 12 in order to provide additional thermal insulation in portions of the jacket 12 that are pressured into contact with the upper body of the wearer . for instance , when the jacket 12 is worn by a firefighter , the shoulder surface of the torso portion 20 benefits from the additional thermal insulation , as the shoulders often bear weights ( e . g ., oxygen tank with strapping , ax or similar tool also with strapping ). accordingly , as shown concurrently in fig1 and 2 , thermal insulation padding is provided at location 23 along the shoulder area of the torso portion 20 . also , when the arms are bent , the elbows of the wearer are pressed against the elbow areas of the arm portions 21 of the jacket 12 . accordingly , thermal insulation padding is provided at location 24 in both the arm portions 21 . although no other padding is illustrated for the jacket 12 , it is considered to position other padding as a function of the contemplated use of the protective garment 10 . referring to fig1 , the trousers 14 are illustrated as having a crotch portion 30 and leg portions 31 . thermal insulation padding is provided at locations 33 in both knee areas , considering that the knees are often pressed against the material of the trousers 14 , when the wearer bends the knees while walking , running , kneeling or while making other like movements . although no other padding is illustrated for the trousers 14 , it is considered to position other padding as a function of the contemplated use of the protective garment 10 . referring to fig3 a to 3 f , a thermal insulation padding , to be used at any one of the aforementioned locations ( e . g ., locations 23 , 24 , 33 ) is illustrated at 40 a to 40 f respectively ( the affixed letter matching the figure identification ), with respect to the material layers of the outer shell 16 , of the moisture barrier liner 17 , and of the thermal barrier liner 18 . more specifically , the thermal insulation padding 40 ( i . e ., any one of the padding 40 a to 40 f ) is positioned between the moisture barrier liner 17 and the thermal barrier liner 18 . the thermal insulation padding 40 a illustrated in fig3 a is made of a sewn fabric , felt or like materials . the padding 40 a has a panel 41 a folded into forming longitudinal pleats 42 a . the pleats 42 a are stitched along their intersection with a plane of the panel 41 a ( i . e ., stitches / seaming 44 a ), and form longitudinal material bumps with air channels 43 a therebetween . therefore , when the padding 40 a is sandwiched between the liners 17 and 18 , air pockets are formed ( i . e ., at the air channels 43 a ). moreover , an increased thickness of padding is provided by the pleats 42 a , to enhance thermal insulation in view of heat conduction . the thermal insulation padding 40 b illustrated in fig3 b is made of a foam , fabric , felt , non - woven fabric that is perforated . the padding 40 b has a panel 41 b provided with a plurality of holes 42 b . therefore , when the padding 40 b is sandwiched between the liners 17 and 18 , air pockets are formed ( i . e ., at the holes 42 b ). the thermal insulation padding 40 c illustrated in fig3 c is made of foam or a non - woven fabric . the padding 40 c has a panel 41 c that is corrugated . accordingly , air channels 42 c and 43 c are formed on opposed sides of the panel 41 c . therefore , when the padding 40 c is sandwiched between the liners 17 and 18 , air pockets are formed ( i . e ., at the air channels 42 c and 43 c ). the thermal insulation padding 40 d illustrated in fig3 d is a mesh pattern made of woven or non - woven fabric , foam tubing or webbing , or the like . the padding 40 d has strips 41 d and 42 d related into an intercrossed configuration . gaps 43 d are defined between the strips 41 d and 42 d . therefore , when the padding 40 d is sandwiched between the liners 17 and 18 , air pockets are formed ( i . e ., by the gaps 43 d ). the thermal insulation padding 40 e illustrated in fig3 e is made of a molded or a sewn material . the padding 40 e has a pair of panels 41 e superposed into forming longitudinal air channels 42 e . in one embodiment , webs are formed by longitudinal stitch lines 43 e that are between the air channels 42 e , but the lines 43 e may also be molded or welded . therefore , when the padding 40 e is sandwiched between the liners 17 and 18 , air pockets are formed ( i . e ., at the air channels 42 e ). inserts 44 e may be provided to ensure that air channels 42 e keep an air content . the thermal insulation padding 40 f illustrated in fig3 f is made of a molded material , or a sewn fabric . the padding 40 f has a pair of panels 41 f superposed into forming air pockets 42 f . therefore , when the padding 40 f is sandwiched between the liners 17 and 18 , air pockets are formed ( i . e ., at the air channels 42 f ). although the thermal insulating padding 40 a to 40 f is respectively illustrated in fig3 a to 3 f between the liners 17 and 18 , it is considered to position the thermal insulation padding 40 a to 40 f between the shell 16 and the liner 17 , or directly between the body and the liner 18 . referring to fig4 , the jacket 12 is shown partly fragmented to illustrate the thermal barrier liner 16 , with respect to the outer shell 16 and the moisture barrier liner 17 . the jacket 12 is fragmented at location 23 to expose the thermal insulation padding at the shoulder area of the jacket 12 . for illustrative purposes , the thermal insulation padding is shown as the thermal insulation padding 40 a of fig3 a , but all other thermal insulation padding described previously could be used . in order to avoid altering the integrity of the layer of material to which it is connected , the thermal insulation padding 40 a is stitched to the seams of the liner . however , the padding 40 a may also in other embodiments be stitched or adhered directly to the various liners . as seen in fig4 , the arm portion 21 has a pair of longitudinal seams 51 ( only one of which is visible ) along the material of the thermal barrier liner 18 . accordingly , in the embodiment of fig4 , the padding 40 a is secured directly on the seam 51 , as illustrated by stitches 50 . therefore , the padding 40 a is fully retained to the arm portion 21 by superposing stitches 50 thereof on seams 51 . opposed edges of the padding 40 a are therefore stitched to the two longitudinal seams 51 of the arm portion 21 . similarly , the padding 40 a used in the shoulder area of the torso portion 20 is secured to the liner 18 by stitching 53 atop the seam 52 .
a protective garment comprises layers of material forming an outer shell so as to protect a wearer of the garment from heat exposure . a thermal insulation padding is attached to the layers so as to be concealed from direct exposure to the environment by the outer shell . the thermal insulation padding has a panel with a longitudinal dimension and bumps of material along the longitudinal dimension formed by pleats in the panel , whereby the thermal insulation padding provides additional insulation to the wearer below the outer shell . a method for securing a thermal insulation padding on a liner of a protective garment is also provided .
