Patent ID: 8408631

Claim:
An adjustable memory track assembly, the track assembly having a first rail adapted to be secured relative to a frame, and a second rail adapted for fore/aft sliding movement relative to the first rail; a track lock assembly operable via a first actuator between a locked, engaged state wherein relative movement between the first and second rails is resisted, and an unlocked, disengaged state wherein the second rail can be slid to and then locked in a user-selected position; a memory module operable via a second actuator to record the user-selected position, the memory module including a memory wheel mounted relative to one of the second rail and first rail, the memory wheel including a plurality of teeth, the teeth adapted to engage openings in a track mounted relative to the other of the second rail and first rail when the memory module is operated; the second actuator operatively connected to disengage the track lock assembly to allow forward movement of the second rail from the user-selected location to a forward location, and thereafter allow rearward movement of the second rail back to, but not past, the user-selected location; characterized in that the memory module is provided with a blocking mechanism adapted to prevent rotation of the memory wheel to prevent rearward movement of the second rail past the user-selected position independent of the locking state of the track lock assembly.
