Bicycle seat

Claim 2

In a bicycle having a longitudinal axis extending generally from the front to the rear thereof, and a mounting attachment for a seat, wherein the improvement comprises an improved seat mounted on said attachment, comprising: an elongated, U-shaped seat frame having a pair of generally parallel upwardly extending legs interconnected by an elongated base portion having a longitudinal axis generally perpendicular to the bicycle longitudinal axis; an elongated, relatively narrow, flexible seating strip formed of a relatively stretch resistant material, extending between said legs above and generally longitudinally centered relative to said seat frame base to define a seat supporting surface extending generally perpendicular to the bicycle longitudinal axis to cradle a rider''s hips or legs; and fastening means securing the opposed ends of said seating strip to a respective seat frame leg, each of said fastening means being independently pivotally interconnected with respect to each respective seat frame leg about an axis generally perpendicular to the bicycle longitudinal axis for independent or simultaneous pivoting of said fastening means to enable pivotal twisting of the seating strip during pedaling or simultaneous pivoting to accomodate different rider positions, said fastening means including cross bar members supporting respective opposed ends of said seating strip, a pin attached to each of said legs, and a member supported by each of said pins and being releasably and swivelly interconnected with each respective cross bar.

Claim 3

For a bicycle having a longitudinal axis extending generally from the front to the rear thereof, and a mounting attachment for a seat; an improved seat mounted on said attachment, comprising: an elongated, U-shaped seat frame having a pair of generally parallel upwardly extending legs interconnected by an elongated base portion having a longitudinal axis generally perpendicular to the bicycle longitudinal axis; an elongated, relatively narrow, flexible seating strip formed of a relatively stretch resistant material, extending between said legs above and generally longitudinally centered relative to said seat frame base to define a seat supporting surface extending generally perpendicular to the bicycle longitudinal axis to cradle a rider''s hips or legs; and fastening means securing the opposed ends of said seating strip to a respective seat frame leg, each of said fastening means being independently pivotally interconnected with respect to each respective seat frame leg about an axis generally perpendicular to the bicycle longitudinal axis for independent or simultaneous pivoting of said fastening means to enable pivotal twisting of the seating strip during pedaling or simultaneous pivoting to accomodate different rider positions, said fastening means including transverse members supporting the respective opposed ends of said seating strip, a support member carried by each of said legs, and interconnecting members supported by respective support members and pivotally interconnecting each support member to a respective transverse member.

Claim 4

For a bicycle having a longitudinal axis extending generally from the front to the rear thereof, and a mounting attachment for a seat; an improved seat mounted on said attachment, comprising: an elongated, U-shaped seat frame having a pair of generally parallel upwardly extending legs interconnected by an elongated base portion having a longitudinal axis generally perpendicular to the bicycle longitudinal axis; an elongated, relatively narrow, flexible seating strip formed of a relatively stretch resistant material, extending between said legs above and generally longitudinally centered relative to said seat frame base to define a seat supporting surface extending generally perpendicular to the bicycle longitudinal axis to cradle a rider''s hips or legs; and fastening means securing the opposed ends of said seating strip to a respective seat frame leg, each of said fastening means being independently pivotally interconnected with respect to each respective seat frame leg about an axis generally perpendicular to the bicycle longitudinal axis for independent or simultaneous pivoting of said fastening means to enable pivotal twisting of the seating strip during pedaling or simultaneous pivoting to accomodate different rider positions, said fastening means including transverse members supporting the respective opposed ends of said seating strip, a support member carried by each of said legs, and interconnecting members supported by respective support members and pivotally interconnecting each support member to a respective transverse member.

Claim 5

The combination as defined in claim 1 and said seating strip being formed of a pair of narrow belt-like strip members, arranged side by side and in a generally common plane.

Claim 6

A bicycle seat as defined in claim 2, and said seating strip comprising a pair of narrow, belt-like strip members arranged side by side in a common plane and on the opposite sides of each of the transverse members.

Claim 7

A bicycle seat as defined in claim 4, characterized by said interconnecting members each extending toWards the opposite leg and being generally axially aligned.

Claim 8

A bicycle seat as defined in claim 4 and said seat frame being formed of an elongated, generally straight, rigid tube having its opposite ends bent upwardly to form said legs, and with a short stub shaft secured to the center of the tube and extending generally downwardly of the seat for securement to the bicycle frame, for thereby fastening the seat to said bicycle frame.
