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.

1. A method for producing a locking device of a longitudinal adjustment device of a vehicle seat, comprising: producing a locking device comprising several round locking pins that can be latched in independently of one another and unlatched together, at least one guide part and a notched strip, wherein the guide part is allocated to a seat rail and has guide bores for the locking pins, the notched strip is allocated to a floor rail, and the locking pins have an upper actuating end and a lower engagement region cooperating with the notched strip, and greasing the locking pins during the production step or subsequent thereto, wherein each individual locking pin is rotationally driven by a rotary drive unit one of during the greasing step, subsequent to the greasing step, or during and subsequent to the greasing step and wherein each individual locking pin is rotated within a respective one of the guide bores. 2. The method according to claim 1, wherein the rotary drive unit in each case carries out at least one complete turn of the locking pin. 3. The method according to claim 1, wherein the rotary drive unit comprises a rotating tool, and a non-circular portion cooperating with the rotating tool is provided in the actuating end of the locking pin. 4. The method according to claim 1, wherein the greasing step is carried out prior to the assembly of the floor rail. 5. The method according to claim 1, wherein the greasing step is carried out by spraying on a grease with a spraying device. 6. The method according to claim 1, wherein, in addition to the rotation of the locking pin by the rotary drive unit, an axial movement of the locking pin by a lift drive unit also takes place. 7. A device for carrying out the method according to claim 1, wherein the device comprises a rotary drive unit that comes into contact with the locking pin and sets the locking pin into rotation. 8. The device according to claim 7, wherein the rotary drive unit comprises a rotating tool, at least one locking pin comprises a non-circular portion, and the rotating tool and the non-circular portion cooperate positively. 9. The device according to claim 1, wherein the device further comprises a lifting device which moves at least one locking pin in the axial direction. 10. A locking device of a longitudinal adjustment device of a vehicle seat, comprising several round locking pins that can be latched in independently of one another and unlatched together, a guide part and a notched strip, wherein the guide part is allocated to a seat rail and has several guide bores for the locking pins, the notched strip is allocated to a floor rail, and the locking pins have an upper actuating end and a lower engagement region cooperating with the notched strip, wherein each locking pin comprises a non-circular portion cooperating with a rotating tool of a rotary drive unit, and the non-circular portion is preferably provided at an end of the locking pin. 11. The method of claim 1, further comprising inserting the locking pins into a respective one of the guide bores prior to greasing the locking pins.
