Abstract

Running rails for securing a motor vehicle seat to a motor vehicle and permitting fore and aft movement of the seat in the direction of the longitudinal axis of the vehicle, including cooperating upper and lower rails each consisting only one profiled member, the lower rail having a generally U-shaped cross section with upwardly extending limbs having upper ends which are bent over forming inwardly extending arcuate parts which define first portions of first and second ball bearing raceways, the upper rail having a wedge shaped portion defining second portions of the first and second ball bearing raceways, and bottom web portions of the upper and lower rails being spaced apart defining a track for roller bearings.
