Abstract: A longitudinal adjuster for a vehicle seat may have at least one seat rail pair, which is formed from a lower seat rail and an upper seat rail, which is guided for sliding in the longitudinal direction relative to the lower seat rail. The two seat rails of the seat rail pair may engage around one another. The lower seat rail or the upper seat rail may have at least one opening. The at least one opening may have an opening cross-section, the two upper corner regions of which each have a curvature portion may have a radius which continuously changes of the course of the curvature portion. A vehicle seat with the adjuster is described.

Abstract: A longitudinal adjuster may have a first transverse locking bar accommodated in a slot of a first seat rail. A spindle may be guided through an opening of the first transverse bar in a contact-free manner. At a distance from the first transverse locking bar toward the front, a shoulder of the spindle is arranged. In reaction to a specified action of force, the first transverse locking bar is clamped between the first seat rail and the shoulder. As a result, a force from the first seat rail via the first transverse locking bar, the shoulder, the spindle, and the spindle nut can be diverted to the second seat rail.
