Easy entry seat assembly system

An adjuster arrangement for adjusting the position of a vehicle seat assembly, said seat assembly having a seat back that is rotatable about a seat cushion from a generally upright use position to a forward easy entry position, said adjuster arrangement comprising:

• inboard and outboard support assemblies adapted for mounting to a vehicle floor, each said support assembly having a longitudinal base adapted to be fixed to the floor providing an upstanding strut at its front end supporting an elevated front pivot, a rear link having a lower end pivoted to an aft end of said base and an upper end pivoted to an aft end of a longitudinal carriage, a guide slot in said carriage receiving said elevated pivot therein allowing carriage slidable travel between front and rear slot limits, a lower rail, fixed on said carriage, slidably supporting an upper track member, fixed to the seat cushion, for longitudinal seat assembly adjustment, whereby with said seat cushion in one of a plurality of adjusted use positions said rear link is inclined rearwardly at a predetermined acute angle with the horizontal, inclining said carriage rearwardly and downwardly from said elevated front pivot;
• a recliner hinge assembly, comprising a seat cushion lower-half hinge pivoted to a seat back upper-half hinge, a release lever pivotable on said hinge upper-half adapted for unlocking said hinge assembly for predetermined forward rotational movement of said seat back, whereby first cable means, interconnecting said seat back with a cam plate pivotally mounted on the inboard track member about an upstanding axis of rotation, rotates said plate in a first direction from an inactive position to an active position thereby unlatching inboard and outboard track latches, supported on respective track members, and allowing forward travel of said seat cushion to a full forward use position, spring means operative for biasing said cam plate in a second rotational direction to said inactive position upon the return of said seat back to its use position;
• said cam plate including a downstanding finger, operative in said cam plate active position, to engage a forward end follower on a longitudinally extending latch arm, said laugh arm having its aft end pivoted on the rear link of said inboard support assembly for biased arm rotation about a transverse axis, extending orthogonal to said cam plate axis, for latched engagement with its associated base, whereby upon said cam plate finger engaging said follower, pivoting said arm out of latched engagement and freeing each said rear link to rotate about its lower end pivot to a forwardly inclined position defining a predetermined acute angle with the horizontal, each said front pivot slides in its associated carriage slot from said front slot limit to said rear slot limit thereby causing each said carriage and seat cushion to be inclined forwardly and downwardly to a seat assembly easy-entry dump position.
