Easy entry seat adjuster assembly with position memory and improved seat return hold open means

In combination with a seat adjuster for a vehicle seat selectively movable between a plurality of fore and aft positions and also having an easy entry mode wherein a releasable memory marker remains fixed, thereby allowing said seat to slide freely forward and return to its original position, said seat adjuster having at least one track with a lower, stationary channel and an upper, slideable channel releasably locked to said lower channel by a spring biased lock bar that rotates freely about a central axis, and in which a manually operated lock bar actuator journaled to said upper channel about said axis rotates said lock bar to an open position against its spring bias while simultaneously disconnecting said memory marker from said lower channel to move with said lock bar actuator to a new adjusted position, and in which a crank freely rotatable about said central axis is activated in easy entry mode as said seat is initially pushed forward to also rotate said lock bar to an open position independently of said manually operated lock bar actuator, and in which said crank is deactivated when said seat is returned to its original position, an improved hold open means to hold said lock bar open as said seat returns to its original position, comprising,

• a housing fixed to said upper channel and having an arcuate slot therein arrayed about said central axis,
• a latch fixed to said housing and having a keeper and a stop extending in one axial direction therefrom, said latch being axially flexible,
• a generally arcuate carrier arm slidably received in said housing slot side by side to said latch and attached to said lock bar so as to rotate therewith through said housing slot and about said central axis, said carrier arm having a window therethrough that circumferentially aligns with said latch keeper as said lock bar is initially rotated open by said crank, and
• a stop member on said memory marker located so as to abut said latch stop member and flex said latch axially away from said carrier arm far enough to move said latch keeper out of said carrier arm window whenever said memory maker maintains its same axial position relative to said lock bar, but which moves axially away from said latch stop to allow said latch to flex back toward said carrier arm to move said latch keeper axially within said carrier arm window when said lock bar moves axially away from said memory marker as said seat slides forward in easy entry mode
• whereby said latch blocking keeper holds said carrier arm stationary to said latch and thereby holds said lock bar open during the return motion of said seat until said latch stop reengages said memory marker stop member to flex said latch away from said carrier arm and push said latch keeper out of said carrier arm window and thereby allow said look bar to relock to said lower channel.
