ABSTRACT:
An installation 10 for the longitudinal adjustment of a seat, especially of a motor vehicle seat which includes a top rail 30 supporting the seat, which is form-lockingly longitudinally displaceably guided on a coordinated bottom rail 44. A drive mechanism 12 with drive pinion 24 is connected with one of the two rails; the drive pinion 24 engages into a toothed rack 56 mounted at the other rail 44 and extending along the same. In order to establish with a simple structure an always reliable mutual engagement of the pinion and toothed rack, also in case of high loads caused by accidents, the other rail 44 is provided with a guide groove 98 for at least one guide bolt 92 mounted at the drive mechanism 14 or at the rail 30 within the area of the pinion 24.
