A longitudinal adjuster comprising:

• a rail profile comprising an upper rail and a lower rail;
• a rail lock for locking and unlocking the rails to each other;
• an actuating mechanism for actuating the rail lock, the actuating mechanism comprising:
• an actuating arm;
• a release lever;
• a positioning element arranged on the release lever and mounted pivotably at a free lever end of the release lever;
• and
• a connection region arranged on the release lever, with an opening fastening the actuating arm in a rotationally fixed manner, wherein the free lever end is configured for arrangement in an inner space of the rails and the connection region is configured so as to be able to pass through an upper side of the upper rail, wherein the free lever end projects into an inner space of the rail profile, and the connection region is guided through an upper side of the upper rail, wherein the connection region comprises a connection region portion located outside of the inner space of the rails, the connection region portion being located at a spaced location from the upper rail.

A longitudinal adjuster comprising:

• a rail profile comprising an upper rail and a lower rail, the upper rail comprising an upper rail opening;
• a rail lock for locking and unlocking the rails to each other;
• an actuating mechanism for actuating the rail lock, the actuating mechanism comprising:
• an actuating arm;
• a release lever;
• a positioning element arranged on the release lever and mounted pivotably at a free lever end of the release lever;
