A vehicle seat support frame includes inboard and outboard support assemblies each having a longitudinal base member providing an upstanding strut supporting an elevated front pivot pin. The base member aft end is formed with a downwardly and rearwardly angled brace having a foot pivotally connected to the lower end of a rear link. The link upper end is pivoted to an aft end of a longitudinal carriage having an elongated side slot receiving the elevated front pivot pin, wherein with the link inclined rearwardly the elevated pin is positioned at a front slot limit. A lower rail, fixed on the carriage, slidably supports an upper track member fixed to a seat cushion frame, for seat assembly adjustment. An easy entry dump arrangement allows a seat back to be pivoted from a normal use position to a forward dump position rotating a track cam plate, thereby unlatching the track members for travel to their full forward position, wherein a cam plate finger contacts a latch am forward end follower to pivot the arm out of latched retention of the rear links. The released links are free to rotate forwardly and slide the carriages on their elevated pins to their rear slot limit positions, whereby the seat cushion travels forwardly along a circular arc, about the link lower pivots, inclining the seat cushion forwardly and downwardly to pass under the instrument panel to its easy entry dump position.

An improved asymmetric wire-hook for a closure one-piece latch wire retainer pivotally mounted to a hinged member wherein the hook is latched upon rotation through an elongated slot of an anchor member. The retainer includes axially aligned wire-lengths terminating in spaced apart opposed bend portions interconnected by the wire-hook. The wire-hook includes one end of a long finger connected to one bend portion and sloped downwardly at a predetermined obtuse-angle relative to one wire length and a short finger connected to the other bend portion and extending downwardly at a right angle relative to the remaining wire length. The long finger lower end terminates in a first acute-angled bend juncture connected to a proximate end of a single lead-in wire segment upwardly sloped at a relatively steep incline while the short finger lower end terminates in a second acute-angle bend juncture connected to a proximate end of a single lead-out wire segment upwardly sloped at a relatively flat incline. The single lead-in and lead-out segments minimizing frictional drag thereby reducing operator effort during closure latching and unlatching with the anchor member slot while the lead-out segment obviates hang-up with a downturned lip defining the slot upper edge.
