Safety slide with rollers for vehicle seats

Claim 1

A safety slide for vehicle seats comprising a lower fixed profile and an upper mobile profile, wherein the upper mobile profile has stiffening longitudinal corrugations, and the lower fixed profile is of a U-shaped section and is formed with vertical wings, said vertical wings being extended by horizontally bent portions and then vertically bent portions for forming, with the stiffening longitudinal corrugations of the upper mobile profile, an upper guiding path for balls and forming a lower rolling path for rollers placed between: (i) said vertically bent portions of the vertical wings of said lower fixed profile, (ii) corresponding vertically bent wing portions formed on the upper mobile profile, and (iii) guiding elements placed in bottom of the upper mobile profile, whereby said rollers are guided, on a one hand, by said vertically bent wing portions of the upper mobile profile and said guiding elements and, on an other hand, by the lower rolling path formed by the wings of the lower fixed profile so as to ensure a considerable transverse strength and a considerable tearing strength of the upper mobile profile with respect to the lower fixed profile.
