Abstract
A vehicle seat slideway has a male channel member whose two flanges are outwardly extended by flaps extending at an angle outwards and towards the web of the male channel member to a vertical end portion, and a female channel member having flanges extended by reentrant troughs penetrating between the flanges and the flaps of the male channel member. Same-diameter balls are disposed firstly between each flap and the corresponding reentrant trough, bearing against at least the vertical end portion of the flap and against a sloping flat portion which extends an initial horizontal portion of the reentrant trough, and secondly against the flap and a corner zone situated at the junction between the web and the corresponding flange of the female channel member.
