Thermal insulation padding for protective garment

Abstract

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.

1 . A protective garment, comprising: 
 at least one layer of material forming an outer shell of the protective garment so as to protect a wearer of the garment from heat exposure;    a thermal insulation padding attached to the at least one layer so as to be concealed from direct exposure to the environment by the outer shell, the thermal insulation padding having 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.    
   
   
       2 . The protective garment according to  claim 1 , wherein the panel generally forms a plane, with the pleats being positioned such that the bumps protrude from the plane, stitches being provided at an intersection between the plane and the bumps.  
   
   
       3 . The protective garment according to  claim 1 , wherein the thermal insulation padding is solely secured to the at least one layer by stitches superposed on seams in the at least one layer.  
   
   
       4 . The protective garment according to  claim 1 , wherein the protective garment has three of the at least one layer, with a first one of the layers being an outer shell, a second one of the layers being a moisture barrier liner, and a third one of the layers being a thermal barrier liner.  
   
   
       5 . The protective garment according to  claim 4 , wherein the thermal insulation padding is positioned between the wearer and the thermal barrier liner.  
   
   
       6 . The protective garment according to  claim 4 , wherein the thermal insulation padding is positioned between moisture barrier liner and the thermal barrier liner.  
   
   
       7 . The protective garment according to  claim 4 , wherein the thermal insulation padding is positioned between outer shell and the moisture barrier liner.  
   
   
       8 . The protective garment according to  claim 1 , wherein the protective garment has a jacket and trousers, with the thermal insulation padding being positioned in at least one of a shoulder area, a forearm area and an elbow area in the jacket, and a knee area in the trousers.  
   
   
       9 . The protective garment according to  claim 1 , wherein the bumps are spaced apart in the padding so as to form channels therebetween.  
   
   
       10 . A method for securing a thermal insulation padding on a liner of a protective garment, comprising the steps of: 
 positioning the thermal insulation padding against the liner such that the thermal insulation padding is superposed with a seam of the liner;    performing at least a first stitch line between the thermal insulation padding and the liner such that the stitch line is on the seam;    whereby the thermal insulation padding is secured to the liner.    
   
   
       11 . The method according to  claim 10 , wherein the first stitch line is performed along a first edge of the thermal insulation padding.  
   
   
       12 . The method according to  claim 11 , wherein a second one of the stitch line is performed along a second edge of the thermal insulation padding along a seam of the liner, with the first edge and the second edge being on opposed sides of the thermal insulation padding.  
   
   
       13 . A protective garment, comprising: 
 at least one layer of material forming an outer shell of the protective garment so as to protect a wearer of the garment from heat exposure;    a thermal insulation padding attached to the at least one layer so as to be concealed from direct exposure to the environment by the outer shell, the thermal insulation padding having a pair of superposed panels with spaced apart longitudinal seam lines interconnecting the panels so as to form air channels between the superposed panels;    whereby the thermal insulation padding provides additional insulation to the wearer below the outer shell.    
   
   
       14 . The protective garment according to  claim 13 , wherein inserts are provided in the air channels.  
   
   
       15 . The protective garment according to  claim 13 , wherein the thermal insulation padding is solely secured to the at least one layer by stitches superposed on seams in the at least one layer.  
   
   
       16 . The protective garment according to  claim 13 , wherein the protective garment has three of the at least one layer, with a first one of the layers being an outer shell, a second one of the layers being a moisture barrier liner, and a third one of the layers being a thermal barrier liner.  
   
   
       17 . The protective garment according to  claim 16 , wherein the thermal insulation padding is positioned between the wearer and the thermal barrier liner.  
   
   
       18 . The protective garment according to  claim 16 , wherein the thermal insulation padding is positioned between moisture barrier liner and the thermal barrier liner.  
   
   
       19 . The protective garment according to  claim 16 , wherein the thermal insulation padding is positioned between outer shell and the moisture barrier liner.  
   
   
       20 . The protective garment according to  claim 13 , wherein the protective garment has a jacket and trousers, with the thermal insulation padding being positioned in at least one of a shoulder area, a forearm area and an elbow area in the jacket, and a knee area in the trousers.
