Abstract

A vehicle seat longitudinal adjuster (106) includes a seat track pair (1) with a lower seat track (2) and an upper seat track (4) that mutually engage one another for guided relative and longitudinal direction (x) movement. The lower seat track (2) has a substantially C-shaped profile (20, 22) with sections (24) that are bent downward at the ends. The upper seat track (4) has a substantially U-shaped profile (40, 42) with end sections (44) that are bent upward; the relative displaceability of the two seat tracks (2, 4) with respect to one another is limited by means of an interaction of an end stop (30) disposed on the lower seat track (2) with a stop element (48) disposed on the upper seat track (4), and wherein the end stop (30) is designed in the form of an extension of part of the downward bent sections (24) and the lower seat track (2) comprises a slotted hole (32) in the region of the end stop (30).
