<p>This is a description of a longitudinal regulating device for vehicle seats comprising a pair of fixed guides (12), fixedly connected to the understructure of the vehicle, and a pair of mobile guides (1), fixedly connected to the vehicle seat and able to slide along said fixed guides, where the fixed guide (12) presents a transverse section substantially in the shape of a U with edges (14) folded outwardly downwards to form surfaces (12b) for the rolling action of a number of rollers (8) interposed between the fixed guide and the mobile guide and a longitudinal recess (12c) suitable for longitudinally guiding and laterally containing vertically folded edges (13) of the mobile guide (1); on each of said edges (13) of the mobile guide are fixed a number of slide blocks (2), longitudinally spaced from each other and comprising: first elastically yieldable means (2a) which are suitable for remaining elastically compressed in a vertical direction against a first surface (12c) of the fixed guide to eliminate vertical clearance between the guides; and second elastically yieldable means (2b) which are suitable for remaining elastically compressed against a second surface (15) of the fixed guide (12) to eliminate transverse clearance between the guides (1, 12). <IMAGE></p> |
