<p>The vehicle seat runner, which allows longitudinal adjustment, has an internal U section (1) extended by curved zones (5,6). The external section (10) has an upper plane (11) edged symmetrically relative to a vertical axis (X-X1), by first guide tracks (14,15). The section is extended by zones (18,19) connecting these tracks to second guide tracks (21,22). Rollers (17,23) are inserted between the first guide tracks and the curved zones and also between curved zones and the second guide tracks. The curved zones enable a slight rotational movement of one section relative to the other. The external section has between each end of the upper plane and the first guide tracks a groove (12,13) which increases the envelope enclosing the rollers installed between the first guide tracks and the curved zones.</p> |
