Abstract: A slide rail for a vehicle seat, comprising two fixed steel sections of U-shaped cross section fitted without play into an identical fixed outer section made by extrusion from a light alloy.

Abstract: An automobile vehicle seat slide includes a generally U-shaped female section having two substantially parallel flanges. The slide also has a generally U-shaped male section with two substantially parallel flanges that slide longitudinally between the flanges of the female section. A lock longitudinally locks the male section to the female section, the lock including an elastically flexible strip located inside the slide and having a first end portion that bears crenelations extending laterally beyond the flanges of the male section and passing through cutouts located in the male section flanges, the crenelations also engaging notches made in the flanges of the female section. The strip includes an attachment end portion located at a second end of the strip, opposite the first end. There is at least one pincer formation stamped in each male section flange for gripping a confronting surface of the attachment end portion thereby maintaining the 87strip against a base of the male section.
