A longitudinal adjuster () for a vehicle seat () includes at least one rail pair () with a longitudinal direction (x) relatively sliding and engaging first seat rail (), for connecting to a seat frame side part (), and a second seat rail (), for connecting to a vehicle structure. A first clamping element (), fastened to the first seat rail and a second clamping element (), fastened to the second seat rail are usually spaced apart from each other and engage with each other, in response to a defined application of force, for example in the event of a crash. The first clamping element has a connection section (), which can be connected to a surface () of a seat frame side part () directed toward the rear. The vehicle seat includes the longitudinal adjuster and a seat frame side part, which is connected to a first seat rail.
