Claim Text:
1. An adjustable memory track assembly for a vehicle seat including: at least one lower rail fixedly attached to a vehicle support structure; at least one upper rail fixedly attached to the vehicle seat bottom, and slidably mounted in one of the at least one lower seat rails, whereby movement of the at least one upper seat rail with respect to the at least one lower seat rail facilitates longitudinal movement of the vehicle seat; a track locking system including at least one locking assembly fixedly attached to one of the at least one pair of upper and lower rails, disposed within the other of the pair of rails, and configured to lock the first rail of the pair in a variety of longitudinal positions with respect to the other rail of the pair, wherein the longitudinal positions vary by a first incremental distance, x; a first actuator operably connected to the seat track locking system and movable between a non-activated position and an activated position whereby the actuator disengages the seat track locking system to allow slidable longitudinal movement of the seat to a first desired location; a memory system for recording the longitudinal seat displacement under certain pre-defined seat positioning conditions, to the extent that such recorded longitudinal seat displacement is equal to an integer multiple of a second incremental distance, y, which second incremental distance, y, is greater than the first incremental distance, x, the memory system including, a memory module mounted on one of the at least one pair of rails and engageable with the other of the pair of rails upon displacement of the seat at a position within the incremental distance y upon activation, to record the displacement, and a second actuator operable to initiate activation of the memory system, the second actuator including an adjustment increment compensator which, in response to the existence of such pre-defined seat positioning conditions, maintains a controlled force sufficient to activate the memory module as soon as the module is engageable, to thereby allow movement of the seat from the first desired location to another location, and thereafter allow movement of the seat back to within the second incremental distance, y, from the first desired location.
