Abstract

An adjustable cycle saddle seat assembly having an in situ operator controlled improved seat position changing apparatus integrally provided therein which comprises a saddle seat having rails assembly nose bumper engaging inside surfaces. A longitudinally extending rails assembly is provided within the saddle seat and has a nose pin engaging rail notch provided therein. The saddle seat is provided with a rail retainer member in .sliding engagement with the rails assembly. A rail assembly support rest member is affixed to the saddle seat and is threadably connected to the rails retainer member by use of a rail guide screw member so as to operatively slidably engage the rails assembly between the rest member and the rails retainer member. A transversely positioned saddle nose pin is fixedly provided in the saddle seat go as to selectively engage the rail notch when the saddle seat is moved to its rear position. A rails assembly nose bumper is fixedly provided in the rails assembly so as to selectively engage the nose bumper engaging inside surfaces of the saddle assembly so as to selectively center the rails assembly when the saddle seat is in its rearward position. An operator controlled actuator is provided in operative engagement with the rails assembly so as to selectively change the relative position of the saddle seat to its respective forward and rear positions on the rails assembly.
