Abstract:
A seat track assembly comprising:an inboard track assembly spaced parallel to an outboard track assembly, each of said inboard and outboard track assemblies including elongated upper and lower tracks extending between forward and rearward ends with said upper tracks slidably coupled to said lower tracks; a locking mechanism operatively coupled between said upper track member and said lower track member for interlocking said upper and lower tracks in a locked position to prevent fore and aft movement therebetween and for unlocking said upper and lower tracks in an unlocked position to provide sliding movement of said upper track along said lower track between a full forward position and a full rearward position; a dumping mechanism operatively coupled between said upper track member and said locking mechanism for retaining said locking mechanism in said unlocked position during said fore and aft sliding movement between said upper and lower tracks and releasing said locking mechanism to said locked position when said upper track reaches a predetermined memory position defined between said full forward and full rearward positions relative to said lower track, said dumping mechanism including a cam plate pivotally connected to said upper track for movement between a non-actuated position spaced from said locking mechanism and an actuated position engaging and retaining said locking mechanism into said unlocked position and a trigger arm pivotally connected to said upper track adjacent said cam plate for selectively engaging and retaining said cam plate in said actuated position and selectively releasing said cam plate to said non-actuated position, said cam plate includes a first end pivotally coupled to one of said upper tracks by a pivot nut, an opposite second distal end, a leading edge extending between said first and second end and an opposite trailing edge extending between said first and second end for engaging said locking mechanism; and a trigger tab projecting from said lower track for engaging and releasing said trigger arm from said cam plate when said upper track reaches said predetermined memory position whereby said cam plate is automatically returned to said non-actuated position and said locking mechanism to said locked position for interlocking said upper and lower track members in said predetermined memory position.
