Abstract

A bicycle seat for a bicycle having a frame with a seat post. A seat base plate is mounted at the upper end of the seat post. Passenger supporting extensions are mounted pivotally on the base plate for limited angular displacement relative to a fore-and-aft centerline of the seat. A cushion member is supported on the base plate, a cushion with a rounded peripheral surface is secured to each extension, the cushion for the base plate having a rounded periphery that registers with the rounded surface of each cushion on the extensions. The cushion for the base plate has a rearward margin defining a shoulder providing a reaction location that accommodates rearward force reaction to forces applied by the right ilium and the left ilium of the pelvis of a bicycle rider. Each cushion for the extensions cooperates with the rounded periphery of the base plate cushion to form a crease that is positioned to receive an ischium extremity of the pelvis of a bicycle rider. The forces distributed to each ischium of the pelvis of a bicycle rider having a fore-and-aft component and a lateral component, thereby providing fore-and-aft stability and lateral stability for the bicycle rider.

Claims8

Dependent claims

A bicycle seat assembly for a bicycle frame to support a rider, the seat assembly being adapted for adjustable compatibility with anatomical characteristics of most riders whereby a rider is supported at left and right rearward support locations and left and right forward support locations;

the seat assembly comprising:
a mounting post;
a base plate secured to the top of the mounting post;
a first cushion attached to an upper surface of the base plate, the periphery of the first cushion being rounded;
a pair of extension plates mounted for pivotal adjustment movement about adjustment axes of on the base plate;
and
a pair of second cushions attached to upper surfaces of the extension plates;
each of the pair of second cushions being rounded;
each of the second cushions and the first cushion having a contoured surface whereby a crease between adjacent contoured surfaces is defined on each lateral side of the base plate;
the spacing of the creases being variable upon pivotal adjustment of the extension plates;
the creases thereby being generally vertically aligned with the left and right forward support locations and the first cushion being generally in alignment with the left and right rearward support locations whereby the rider has support with both lateral stability and fore-and-aft stability.
