<p>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 itermittently 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). The movable supporting structure (33) is spring (104) biased to move the seat (72), after unweighting by the rider or operator, in a generally forward and upward direction upon activation of the actuating control (106), which releases the releasable locking mechanism (37), which, itself, is lockably biased enabling it to find and relock into another detent-type intermittently lockable position, after which, the movable supporting structure (33), upon being freed to move again by release of the releasable locking mechanism (37) by activation of the actuating control (106) by the rider or operator, can enable the seat (72) to move in a generally rearward and downward direction from a rearward weighting by the rider or operator, when, again, the lockably biased releasable locking mechanism (37) will find and relock into another detent-type intermittently lockable position.</p> |
