Abstract

A method for producing a locking device of a longitudinal adjustment mechanism of a vehicle seat, includes producing a locking device having a plurality of round locking pins which can be latched into position independently of one another and can be unlatched together, at least one guide part and a notched strip, wherein the guide part is assigned to a seat rail and has guide bores for the locking pins. The notched strip is assigned to a floor rail. The locking pins have an upper actuating end and a lower engagement region interacting with the notched strip. The locking pins are lubricated during the production step or subsequently thereto. During and/or after the lubrication step, each individual locking pin is rotationally driven by a rotary drive unit.
