Abstract
Abstract A bicycle seat cover with which friction on the bicyclist is minimized. This end result is achieved by providing the cover with a compliant central portion which may be fabricated of a polyurethan foam, this central portion having a middle layer thereover of a low friction material, such as a polyethylene, and finally an outer layer over the polyethylene layer which is of soft material and which has an inner surface of low friction material, such as an acrylic resin coating, and an outer surface of a soft material, such as a suitable nylon. The outer cover fits over the bicycle seat and has an elastic ring-shaped band on the bottom portions thereof which grips the cover to the bicycle seat.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
97 words
A bicycle seat cover comprising an inner central portion of a compliant material, a middle layer covering at least the top surface of said central portion, said middle layer being of a material having a low friction outer surface, and an outer layer covering at least the top surface of said middle layer having an outer surface of substantially higher friction than the inner surface thereof such that the clothing and body portions contacting said outer layer will tend to frictionally engage the outer surface thereof with slidable motion being permitted between the outer and middle layers.
Claim 2
Dependent Claim
97 words
A bicycle seat cover comprising an inner central portion of a compliant material, a middle layer covering at least the top surface of said central portion, said middle layer being of a material having a low friction outer surface, and an outer layer covering at least the top surface of said middle layer having an outer surface of substantially higher friction than the inner surface thereof such that the clothing and body portions contacting said outer layer will tend to frictionally engage the outer surface thereof with slidable motion being permitted between the outer and middle layers.
Claim 3
Dependent Claim
25 words
The bicycle seat cover of claim 1 wherein the middle layer completely surrounds the central portion and has low friction inner and outer surfaces throughout.
