Full memory seat track mechanism

A seat track assembly providing forward and rearward movement of a seat assembly along a floor in an automotive vehicle, said seat track assembly comprising:

• a fixed track adapted to be fixedly secured to the floor;
• a movable track adapted to be fixedly secured to the seat assembly and slidably coupled to said fixed track;
• a latch mechanism operatively coupled between said fixed and movable tracks, wherein said latch mechanism prevents sliding movement of said movable track and is selectively disengaged from said fixed track to allow sliding movement of said movable track between a plurality of positions;
• and
• a memory mechanism operable between a home position, wherein said memory mechanism is coupled with said movable track and moves therewith during sliding movement of said movable track, and a memory position, wherein said memory mechanism is coupled with said fixed track and defines a previously selected one of said plurality of positions, wherein said memory mechanism includes a memory plate operatively coupled to said movable track and biased towards said home position, said memory plate is disengaged from said fixed track when said memory mechanism is in said home position and said memory plate is engaged with said fixed track when said memory mechanism is in said memory position;
• wherein actuation of said memory mechanism to said memory position disengages said latch mechanism from said fixed track, thereby allowing sliding movement of said movable track in a first direction away from said previously selected one of said plurality of positions to an easy-entry position, and in response to sliding movement of said movable track in a second direction from said easy-entry position said memory mechanism blocks said movable track at said previously selected one of said plurality of positions, thereby allowing said latch mechanism to engage with said fixed track and said memory mechanism to return to said home position;
• wherein said movable track includes an elongated slot extending between first and second ends, said elongated slot having a recess at said first end and said memory plate having a memory tab extending laterally from a first end of said memory plate, said memory plate is slidably coupled to said elongated slot and said memory tab is disposed in said recess when said memory mechanism is in said home position and said memory tab is withdrawn from said recess when said memory mechanism is in said memory position;
• wherein said first end of said elongated slot contacts said memory tab to block said movable track at said previously selected one of said plurality of positions in response to sliding movement of said movable track in said second direction and wherein said fixed track includes an elongated tooth rack and said memory plate includes at least one memory tooth, said at least one memory tooth engaged with said tooth rack when said memory mechanism is in said memory position;
• and wherein said latch mechanism is independently operable to disengage said latch mechanism from said fixed track when said memory mechanism is in said home position.
