Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 268 words
A bicycle seat of the type having a flexible shell portion including a narrow leading edge portion with a downwardly turned tip, a wider trailing end portion with a centermost portion, a first relatively thinned and flexible pelvic zone lying along one side of said centermost portion for flexibly supporting one portion of the pelvic region of a cyclist, a second relatively thinned and flexible pelvic zone lying along the other side of said centermost portion for flexibly supporting another portion of the cyclist's pelvic region, said seat further has downwardly turned side portions located on each side of said seat adjacent each of said thinned pelvic regions and with said centermost portion of said trailing end and said side portions located along said trailing end each having a larger transverse cross-sectional dimension than each of said thinned pelvic zones, the improvement wherein an amount of padding material is distributed over said flexible shell including each of said thinned pelvic zones, said centermost portion and said downwardly turned side portions, with a larger amount of said padding being distributed over said thinned pelvic zones than is distributed over the remaining portions of said shell to form bumps of padding over each of said thinned pelvic zones such that when a cyclist's pelvic region contacts said bumps over said thinned zones, said padding bumps are depressed as the padding under said bumps is distributed over said thinned zones in a downwardly direction, said padding under said bumps over said thinned zones being further distributed over said centermost and said side portions of said seat to provide for cyclist comfort.
