A seat track assembly for an adjustable seat with positive engagement is disclosed and has a lower track assembly with at least one lower track having a plurality of spaced slots and an upper track assembly with at least one lower track. The upper track is slidable over the lower track. A latch is movable from a latching position securing the upper track with respect to the lower track to an unlatching position where the upper track is free to slide over the lower track. The latch comprises a plurality of locking pawls mounted on the upper track, with each locking pawl having a first tooth and a second tooth and each tooth has a front face and a rear face. In the latching position the first tooth of a first one of the locking pawls is received within a first slot and the second tooth of the first one of the locking pawls is received within a second slot. In accordance with certain preferred embodiments the width of each slot is twice the slot width, the pawls are separated from one another by a distance equivalent to the width of each tooth, the slots are separated by a distance generally equal to the width of each tooth.
