Publication number: 20240140274Abstract: A longitudinal adjuster may have one pair of rails and a drive device for the pair of rails. The pair of rails has a first rail and a second rail, on which the first rail is guided displaceably. The drive device has a geared motor with an output shaft, a motor, a gear unit, a spindle, and a coupling arrangement for coupling the spindle and the output shaft. The spindle is mounted rotatably about a spindle axis. The coupling arrangement may have a flexible coupling which is connected in a form-fitting and/or force-fitting manner on the one hand to a spindle end and on the other hand to a shaft end of the output shaft and is designed to damp vibrations and/or to compensate for an offset between the spindle end and the shaft end.
