Rail and vehicle seat

A longitudinal adjuster comprising:

• at least one seat rail pair which is formed by a lower seat rail and an upper seat rail which is displaceably guided relative to the lower seat rail in a longitudinal direction,
• wherein the two seat rails of the seat rail pair mutually engage around each other,
• wherein the lower seat rail has a substantially C-shaped profile with end portions which are bent downward and the upper seat rail has a substantially U-shaped profile having end portions which are bent upward;
• an end stop;
• and
• a stop element,
• wherein a relative displaceability of the two seat rails with respect to each other is limited by a cooperation of the end stop, which is arranged on the lower seat rail, with the stop element, which is integrally formed from the upper seat rail, wherein a free cut is only located on three sides of the stop element in the upper rail,
• wherein the stop element is integrally formed from said upper seat rail first by two bridges extending transverse the longitudinal direction from said upper seat rail, wherein said bridges extend on either side of a stop element opening, and second by a web extending between the bridges and parallel the longitudinal direction, wherein said stop element opening extends from said web to a connection point between said bridges and said upper seat rail,
• wherein the end stop is integrally formed from the downwardly bent portions and the lower seat rail has an elongate hole adjacent to the end stop;
• wherein the end stop has two adjacent stop faces which are, viewed in a transverse direction, arranged at an obtuse angle relative to each other.
