Abstract

La présente invention concerne un dispositif de glissières de siège qui empêche les défauts de fonctionnement des organes de mise en oevre. En l'occurrence, on utilise un élément de verrouillage (50) pour maintenir (verrouiller) un rail supérieur (20) solidaire du siège d'automobile et un rail inférieur (30) solidaire du plancher de l'automobile par l'intermédiaire d'un sabot antérieur et d'un sabot postérieur, de façon à les rendre fixes l'un par rapport à l'autre. L'élément de verrouillage (50) pivote autour d'un centre de pivotement (L) sur lequel prend naissance un taquet de verrouillage (55) d'un élément pivotant (50b), lequel taquet se présente dans l'axe du coulissement. Le pivotement se produit en réaction à l'actionnement d'un levier de manoevre. Le centre de pivotement (L) se situe à distance du taquet de verrouillage (55).
