Abstract
An electro-mechanical dual linear drive system for adjustably power moving a watercraft seat along a linear travel path. A pair of elongate extruded hollow aluminum rails are mounted in parallelism to a fixed seat support structure. An elongate extruded aluminum hollow slide is non-rotatably and slidably mounted within each rail and driven in a linear travel path for moving the seat load. A lead screw is rotatably mounted within each slide and rail and a traveling nut on each lead screw moves the associated slide. A gear reduction drive mounted on each rail is driving coupled for rotating the associated lead screw. A single electric motor is rotationally drivingly coupled to both gear drive units for synchronously rotating the lead screws in response to motor rotation. Each rail and slide are non-circular and complementary for restraining relative rotation therebetween. A laterally protruding flange along one side edge of the rail bottom wall provides an exteriorly accessible mounting flange on the rail. Likewise, each slide has a planar mounting platform protruding laterally in offset relation to the associated rail to provide seat load fastening access clearance. At least two gli…
