An interlocking track arrangement for a seat slide device of the type used in manually-operable vehicle seat slide mechanisms is disclosed. The seat slide device also includes a latching arrangement having a lock plate fixed to a lower track and a latch plate supported from an upper track for rectilinear movement along a vertical plane. The latch plate has a plurality of locking teeth each having a segmented toothform defined by a first locking portion for facilitating initial receipt within a locking aperture formed in the lock plate, a second locking portion for facilitating complete interdigitated engagement therebetween, and a camming portion providing a ramped transition between the first and second locking portions. The rectilinear movement of the latch plate along the vertical plane provides improved operation and reliability.
