Abstract: A seat rail pair for a vehicle seat is disclosed. The seat rail pair may have a lower rail and an upper rail. The upper rail may be moved relative to the lower rail via mutually engaged profiles. The lower rail may have a substantially C-shaped profile and the upper rail may have a substantially U-shaped profile. Roller members may be arranged between the upper rail and the lower rail to facilitate relative movement.

Abstract: A seat rail pair (1) for a vehicle seat, in particular for a motor vehicle seat, includes a lower rail (2) and an upper rail (4). The upper rail (4) is guided displaceably in the longitudinal direction relative to the lower rail (2). Profiles of the rails are mutually in engagement. The lower rail (2) has a substantially C-shaped profile (20, 22) with portions (24) bent downwards at the ends. The upper rail (4) has a substantially U-shaped profile (40, 42) with end portions (44) bent upwards. Rolling bodies (8a, 8b) are arranged in two lower rolling-body raceways (10a) and two upper rolling-body raceways (10b) between the lower rail (2) and the upper rail (4). A part of the end portions (44) making contact with the rolling bodies (8a) arranged in the lower rolling-body raceways (10a) has a flat supporting surface (46).
