This seat adjuster is useful interchangeably as either a right or left-hand unit, thus eliminating the necessity for providing two slightly different units to form a pair. The latch in each unit is of elongated form and slidably guided at opposite ends in registering holes in the opposite side walls of an inverted channel bracket carried on the upper movable slide so as to operate crosswise relative to a lower fixed track channel in slots provided in registering relation in the opposite side walls thereof. A channel portion intermediate the ends of the latch has the edge portions of its side walls engaging in neighboring notches provided in evenly spaced relation along one side of the aforesaid slots, thus providing four points of interlocking engagement as against only two in previous constructions. The latch has compression springs caged under preload on its opposite ends on extensions of the web portion of the channel between attaching brackets staked onto the ends of the extensions and washers slidably guided on the extensions and abutting the opposite side walls of the fixed lower track channel, so the latch is normally held in locked position under balanced spring pressure but can be pulled endwise in either direction to unlocked position in which elongated notches in the upper edges of the side walls of the channel register with the one set of notches in one of the slotted side walls of the fixed lower track while the one end of the channel also comes clear of the other set of notches in the other side wall of the fixed lower track.
