Abstract A protective suit is provided in order to protect the wearer from skin abrasions as he slides along or otherwise comes in contact with a rough surface. The protective suit includes an outer material as well as a lining. Intermediate these are a plurality of layers of a material having a surface with a low coefficient of friction. Each of the layers of material has a high breaking elongation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
115 words
A protective suit comprising, in combination, an outer material; a lining; and a plurality of layers of protective material intermediate said outer material and said lining and lying upon each other with a low coefficient of friction between each of the layers, each of said layers having edges, said layers being connected only at their edges to each other and to said lining, said layers each having a high breaking elongation whereby when an individual layer of protective material is stretched after directly contacting a rough surface, another individual layer directly beneath it remains at least substantially unstressed due to the low coefficient of friction at least until the first-mentioned individual layer is worn away.
Claim 2
Dependent Claim
115 words
A protective suit comprising, in combination, an outer material; a lining; and a plurality of layers of protective material intermediate said outer material and said lining and lying upon each other with a low coefficient of friction between each of the layers, each of said layers having edges, said layers being connected only at their edges to each other and to said lining, said layers each having a high breaking elongation whereby when an individual layer of protective material is stretched after directly contacting a rough surface, another individual layer directly beneath it remains at least substantially unstressed due to the low coefficient of friction at least until the first-mentioned individual layer is worn away.
Claim 3
Dependent Claim
21 words
The suit defined in claim 1, at least some of said layers consisting of fibers which are interlaced with each other.
Claim 4
Dependent Claim
16 words
The suit defined in claim 2, at least some of said layers being a spun-bonded fabric.
Claim 5
Dependent Claim
16 words
The suit defined in claim 2, at least some of said layers consisting of polyester fibers.
Claim 6
Dependent Claim
16 words
The suit defined in claim 1, at least some of said layers being a spun-laced fabric.
Claim 7
Dependent Claim
24 words
The suit defined in claim 1, said outer material being likewise a material having a high breaking elongation and a low coefficient of friction.
Claim 8
Dependent Claim
15 words
The suit defined in claim 1, said plurality of layers comprising eight of said layers.
