Abstract
Abstract A padding device is provided comprising a flowable material and/or low compression set foam. The flowable material comprises discrete particles dispersed in a wax and oil base. The padding device is particularly suitable for use in seating cushions, including bicycle seat cushions. A method for securing the padding device to a bicycle seat is also disclosed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
125 words
A padding device comprising: (1) a bicycle seat cover; (2) a low compression set foam located within said cover and having an ASTM constant deflection compression set for a 50% deflection, of greater than 10%, expressed as a percentage of original thickness, and (3) flowable material located at selected positions within said cover and overlapping at least portions of said low compression set foam, wherein said flowable material is resistant to flow in response to instantaneously applied pressure and flows in response to continuously applied pressure, said flowable material being further characterized in that it is capable of deforming into an irregular shape in response to said continuously applied pressure and is capable of substantially retaining said irregular shape after all applied pressure is removed.
Claim 2
Dependent Claim
125 words
A padding device comprising: (1) a bicycle seat cover; (2) a low compression set foam located within said cover and having an ASTM constant deflection compression set for a 50% deflection, of greater than 10%, expressed as a percentage of original thickness, and (3) flowable material located at selected positions within said cover and overlapping at least portions of said low compression set foam, wherein said flowable material is resistant to flow in response to instantaneously applied pressure and flows in response to continuously applied pressure, said flowable material being further characterized in that it is capable of deforming into an irregular shape in response to said continuously applied pressure and is capable of substantially retaining said irregular shape after all applied pressure is removed.
Claim 3
Dependent Claim
154 words
A padding device comprising: (1) a low compression set foam located at selected first positions within the padding device, said foam having an ASTM constant deflection compression set for a 50% deflection, of greater than 10%, expressed as a percentage of original thickness, and (2) flowable material located at selected second positions within said padding device wherein said flowable material overlaps at least portions of said low compression set foam, said flowable material comprising a first layer of flowable material and a second layer of flowable material, at least partially overlapping said first layer, said flowable material being resistant to flow in response to instantaneously applied pressure and flows in response to continuously applied pressure, said flowable material being further characterized in that it is capable of deforming into an irregular shape in response to said continuously applied pressure and is capable of substantially retaining said irregular shape after all applied pressure is removed.
Claim 4
Dependent Claim
