ABSTRACT:
A slide for a vehicle seat comprises a first bar having a narrow channel section with vertical flanges that are extended outwardly by rims, and a second bar having a wide upside-down channel section enveloping the first bar with the ends of the vertical flanges being extended inwardly by reentrant troughs, the two bars being shaped to form four ball tracks between them. Each outer vertical flange has an outwardly directed ridge, and each rim has an extension suitable for hooking against the inside face of a ridge when a vertical force is exerted tending to pull the two bars apart.
