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.

Abstract: A seat position changing apparatus, controllable by a riding bicycle rider or operating cycle type machine operator, comprising a movable supporting structure (33), a releasable locking mechanism (37), and a handlebar (109) mounted actuating control (106), enabling multi-directional combined movement of the seat (72) within a plurality of detent-type intermittently lockable positions, by, an identically repeatable triggering-type activating action by the rider or operator of the actuating control (106), which is connected by a cable (46) to the releasable locking mechanism (37).
