Abstract
A firefighter protective garment includes an external material and at least one abrasion resistant hem assembly. The external material has an inner surface and the at least one abrasion resistant hem assembly includes a strip of reinforcing material affixed along an edge of the firefighter protective garment to the inner surface of the external material by a fastener. The fastener is embedded within the external material.
Claims23
A firefighter protective garment, comprising:
- an external material having an inner surface;
- and
- at least one abrasion resistant hem assembly comprising:
- a strip of reinforcing material positioned along an edge of the firefighter protective garment inwardly of the external material, the strip of reinforcing material having abrasion-resistance properties providing protection against mechanical forces encountered during firefighting activities, the strip of reinforcing material comprising:
- a first end portion affixed to the inner surface of the external material by a fastener, the fastener being embedded within the external material;
- a second end portion affixed to the first end portion, the first end portion being sandwiched between the inner surface of the external material and the second end portion;
- and
- a channeled cuff portion extending outwardly from the edge of the firefighter protective garment, the channeled cuff portion being formed by longitudinally folding the strip of reinforcing material and joining the second end portion with the first end portion;
- and
- a reinforcing cord inserted in the channeled cuff portion, the reinforcing cord having a substantially circular cross-section configured to reduce a concentration of frictional contacts near the edge of the firefighter protective garment by rounding an external edge of the strip of reinforcing material.

A firefighter protective coat having a pair of sleeves, comprising:
- an outer shell providing protection against mechanical attacks and heat, the outer shell having an inner surface;
- and
- a pair of abrasion resistant hem assemblies, each associated with a corresponding sleeve of said pair of sleeves, each abrasion resistant hem assembly comprising:
- a reinforcing strip made of a material having abrasion-resistance properties providing protection against mechanical forces encountered during firefighting activities, the reinforcing strip being positioned inwardly of the outer shell along an edge of the corresponding sleeve, the reinforcing strip comprising;
- a first end portion affixed to the inner surface of the outer shell by a fastener, the fastener comprising at least one row of stitching embedded within the outer shell;
- a second end portion affixed to the first end portion, the first end portion being sandwiched between the inner surface of the outer shell and the second end portion;
- and
- a channeled cuff portion extending outwardly of the edge of the corresponding sleeve, the channeled cuff portion being formed by longitudinally folding the reinforcing strip and joining the second end portion with the first end portion;
- and
- a reinforcing cord extending in the channeled cuff portion, the reinforcing cord having a substantially circular cross-section configured to reduce a concentration of frictional contacts near the edge of the corresponding sleeve by rounding an external edge of the reinforcing strip.

Firefighter protective pants having a pair of legs, comprising:
- an outer shell providing protection against mechanical attacks and heat, the outer shell having an inner surface;
- and
- a pair of abrasion resistant hem assemblies, each associated with a corresponding leg of said pair of legs, each abrasion resistant hem assembly comprising:
- a reinforcing strip made of a material having abrasion-resistance properties providing protection against mechanical forces encountered during firefighting activities, the reinforcing strip being positioned inwardly of the outer shell along an edge of the corresponding leg, the reinforcing strip comprising:
- a first end portion affixed to the inner surface of the outer shell by a fastener, the fastener comprising at least one row of stitching embedded within the outer shell;
- a second end portion affixed to the first end portion, the first end portion being sandwiched between the inner surface of the outer shell and the second end portion;
- and
- a channeled cuff portion extending outwardly of the edge of the corresponding leg, the channeled cuff portion being formed by longitudinally folding the reinforcing strip and joining the second end portion with the first end portion;
- and
- a reinforcing cord extending in the channeled cuff portion, the reinforcing cord having a substantially circular cross-section configured to reduce a concentration of frictional contacts near the edge of the corresponding leg by rounding an external edge of the reinforcing strip.
