Abstract

L'invention concerne un fourreau (103) d’une colonne de direction comportant un tube extérieur (101) et un tube intérieur (102) mobiles l’un par rapport à l’autre et un système de réglage (10) comprenant une vis de réglage (200) de la position axiale s’étendant suivant un axe de réglage (X’) solidaire en translation d’un premier (101) des deux éléments (101, 102) au moyen d’au moins deux paliers de guidage (211, 212) pour guider la vis de réglage (200) en rotation autour de l’axe de réglage (X’), le fourreau de la colonne de direction (103) étant caractérisé en ce qu’au moins un des paliers (211, 212) supportant la vis de réglage (200) est un palier de guidage à reprise d’effort axial pour bloquer en translation la vis de réglage (200), le moteur (11) étant déporté desdits paliers (211, 212). (Fig. 1)The invention relates to a sleeve (103) of a steering column comprising an outer tube (101) and an inner tube (102) movable relative to each other and an adjustment system (10) comprising a screw adjustment (200) of the axial position extending along an adjustment axis (X') integral in translation with a first (101) of the two elements (101, 102) by means of at least two guide bearings ( 211, 212) to guide the adjustment screw (200) in rotation around the adjustment axis (X'), the sleeve of the steering column (103) being characterized in that at least one of the bearings (211 , 212) supporting the adjusting screw (200) is a guide bearing with axial force absorption to lock the adjusting screw (200) in translation, the motor (11) being remote from said bearings (211, 212). (Fig.1)
